1 00:00:00,000 --> 00:00:17,000 When people say we don't believe in global warming, I say no, I believe in global warming. 2 00:00:17,000 --> 00:00:20,360 I don't believe that human CO2 is causing that warming. 3 00:00:20,360 --> 00:00:23,320 A few years ago, if you would ask me, I would tell you it's CO2. 4 00:00:23,320 --> 00:00:24,320 Why? 5 00:00:24,320 --> 00:00:29,560 Because just like everyone else in the public, I listened to what the media had to say. 6 00:00:30,200 --> 00:00:35,280 Each day, the news reports grow more fantastically apocalyptic. 7 00:00:35,280 --> 00:00:39,280 Politicians no longer dare to express any doubt about climate change. 8 00:00:39,280 --> 00:00:44,160 There is such intolerance of any dissenting voice. 9 00:00:44,160 --> 00:00:47,960 Some of the worst climate criminals on the planet. 10 00:00:47,960 --> 00:00:55,640 This is the most politically incorrect thing possible, is to doubt this climate change orthodoxy. 11 00:00:55,720 --> 00:00:58,400 Global warming has gone beyond politics. 12 00:00:58,400 --> 00:01:00,600 It is a new kind of morality. 13 00:01:00,600 --> 00:01:07,080 The Prime Minister is back from his holidays, unrepentant and unembarrassed about yet another long haul destination. 14 00:01:09,480 --> 00:01:13,640 Yet, as the frenzy of a man-made global warming grows shriller, 15 00:01:13,640 --> 00:01:20,080 many senior climate scientists say the actual scientific basis for the theory is crumbling. 16 00:01:20,080 --> 00:01:24,600 There were periods, for example, in Earth's history when we had three times as much CO2 as we have today, 17 00:01:24,600 --> 00:01:27,560 or periods when we had ten times as much CO2 as we have today. 18 00:01:27,560 --> 00:01:33,040 And if CO2 has a large effect on climate, then you should see it in the temperature reconstruction. 19 00:01:34,040 --> 00:01:40,120 If we look at climate through the geological time frame, we would never suspect CO2 as a major climate driver. 20 00:01:40,120 --> 00:01:47,360 None of the major climate changes in the last thousand years can be explained by CO2. 21 00:01:47,360 --> 00:01:51,720 We can't say that CO2 will drive climate. It certainly never did in the past. 22 00:01:51,840 --> 00:01:58,600 I've often heard it said that there is a consensus of thousands of scientists on the global warming issue, 23 00:01:58,600 --> 00:02:01,880 and that humans are causing a catastrophic change to the climate system. 24 00:02:01,880 --> 00:02:06,560 Well, I am one scientist, and there are many that simply think that is not true. 25 00:02:06,560 --> 00:02:10,280 Man-made global warming is no ordinary scientific theory. 26 00:02:10,280 --> 00:02:13,200 This morning, the Intergovernmental Panel on Climate Change made up of... 27 00:02:13,200 --> 00:02:18,880 It is presented in the media as having the stamp of authority of an impressive international organisation. 28 00:02:18,880 --> 00:02:20,320 ...from the IPCC... 29 00:02:20,560 --> 00:02:26,160 The United Nations Intergovernmental Panel on Climate Change, or IPCC. 30 00:02:26,160 --> 00:02:33,360 The IPCC, like any UN body, is political. The final conclusions are politically driven. 31 00:02:33,360 --> 00:02:42,280 This claim that the IPCC is the world's top 1,500 or 2,500 scientists, 32 00:02:42,280 --> 00:02:45,360 you look at the bibliographies of the people and it's simply not true. 33 00:02:45,360 --> 00:02:48,040 There are quite a number of non-scientists. 34 00:02:48,080 --> 00:02:54,640 And to build the number up to 2,500, they have to start taking reviewers and government people and so on, 35 00:02:54,640 --> 00:03:02,000 anyone who ever came close to them. And none of them are asked to agree. Many of them disagree. 36 00:03:02,000 --> 00:03:07,800 Those people who are specialists but don't agree with the polemic and resign, 37 00:03:07,800 --> 00:03:12,840 and there have been a number that I know of, they are simply put on the author list 38 00:03:12,840 --> 00:03:16,400 and become part of this 2,500 of the world's top scientists. 39 00:03:16,440 --> 00:03:21,840 Some people have decided you have to convince other people that since no scientist disagrees, 40 00:03:21,840 --> 00:03:28,040 you shouldn't disagree either. But whenever you hear that in science, that's pure propaganda. 41 00:03:30,400 --> 00:03:35,400 This is the story of how a theory about climate turned into a political ideology. 42 00:03:36,800 --> 00:03:39,200 See, I don't even like to call it the environmental movement anymore, 43 00:03:39,200 --> 00:03:45,800 because really it is a political activist movement, and they have become hugely influential at a global level. 44 00:03:47,400 --> 00:03:51,400 It is the story of the distortion of a whole area of science. 45 00:03:51,400 --> 00:03:56,400 Climate scientists need there to be a problem in order to get funding. 46 00:03:56,400 --> 00:04:03,400 We have a vested interest in creating panic, because then money will flow to climate science. 47 00:04:03,400 --> 00:04:09,400 There's one thing you shouldn't say, and that is, this might not be a problem. 48 00:04:10,400 --> 00:04:16,400 It is the story of how a political campaign turned into a bureaucratic bandwagon. 49 00:04:16,400 --> 00:04:21,400 The fact of the matter is that tens of thousands of jobs depend upon global warming right now. 50 00:04:23,400 --> 00:04:25,400 It's a big business. 51 00:04:25,400 --> 00:04:30,400 It's become a great industry in itself. 52 00:04:30,400 --> 00:04:38,400 And if the whole global warming farago collapsed, there'd be an awful lot of people out of jobs and looking for work. 53 00:04:39,400 --> 00:04:43,400 This is a story of censorship and intimidation. 54 00:04:43,400 --> 00:04:54,400 I have seen and heard their spitting fury at anybody who might disagree with them, which is not the scientific way. 55 00:04:54,400 --> 00:05:03,400 It is a story about Westerners invoking the threat of climatic disaster to hinder vital industrial progress in the developing world. 56 00:05:03,400 --> 00:05:16,400 One clear thing that emerges from the whole environmental debate is the point that there's somebody keen to kill the African dream, and the African dream is to develop. 57 00:05:16,400 --> 00:05:26,400 The environmental movement has evolved into the strongest force there is for preventing development in the developing countries. 58 00:05:27,400 --> 00:05:36,400 The global warming story is a cautionary tale of how a media scare became the defining idea of a generation. 59 00:05:36,400 --> 00:05:40,400 The whole global warming business has become like a religion. 60 00:05:40,400 --> 00:05:46,400 And people who disagree are called heretics. 61 00:05:46,400 --> 00:05:48,400 I'm a heretic. 62 00:05:48,400 --> 00:05:52,400 The makers of this program are all heretics. 63 00:05:56,400 --> 00:06:06,400 In 2005, a House of Lords inquiry was set up to examine the scientific evidence of man-made global warming. 64 00:06:06,400 --> 00:06:18,400 A leading figure in that inquiry was Lord Lawson of Blaby, who, as Chancellor of the Exchequer in the 1980s, was the first politician to commit government money to global warming research. 65 00:06:19,400 --> 00:06:28,400 We had a very, very thorough inquiry, took evidence from a whole lot of people, experts in this area, and produced a report. 66 00:06:28,400 --> 00:06:34,400 What surprised me was to discover how weak and uncertain the science was. 67 00:06:34,400 --> 00:06:47,400 In fact, there are more and more thoughtful people, some of them a little bit frightened to come out in the open, but who quietly, privately, and some of them publicly are saying, hang on, wait a minute, this simply doesn't work. 68 00:06:47,400 --> 00:06:49,400 This simply doesn't add up. 69 00:06:51,400 --> 00:06:55,400 We are told that the Earth's climate is changing. 70 00:06:57,400 --> 00:07:00,400 But the Earth's climate is always changing. 71 00:07:00,400 --> 00:07:12,400 In Earth's long history, there have been countless periods when it was much warmer and much cooler than it is today, when much of the world was covered by tropical forests or else vast ice sheets. 72 00:07:12,400 --> 00:07:17,400 The climate has always changed, and changed without any help from us humans. 73 00:07:18,400 --> 00:07:26,400 We can trace the present warming trend back at least 200 years, to the end of a very cold period in Earth's history. 74 00:07:26,400 --> 00:07:31,400 This cold spell is known to climatologists as the Little Ice Age. 75 00:07:31,400 --> 00:07:34,400 Let it snow, let it snow, let it snow. 76 00:07:34,400 --> 00:07:37,400 It doesn't show signs to stop... 77 00:07:37,400 --> 00:07:41,400 In the 14th century, Europe plunged into the Little Ice Age. 78 00:07:41,400 --> 00:07:50,400 And where we would look for evidence of this are the old illustrations and prints and pictures of Old Father Thames. 79 00:07:50,400 --> 00:07:57,400 Because during the hardest and toughest winters of that Little Ice Age, the Thames would freeze over. 80 00:07:58,400 --> 00:08:06,400 And there were wonderful ice fairs held on the Thames, skating and people actually selling things on the ice. 81 00:08:09,400 --> 00:08:20,400 If we look back further in time, before the Little Ice Age, we find a balmy golden era, when temperatures were higher than they are today, a time known to climatologists as the medieval warm period. 82 00:08:27,400 --> 00:08:35,400 It's important that people know that climate enabled a quite different lifestyle in the medieval period. 83 00:08:35,400 --> 00:08:41,400 We have this view today that warming is going to have apocalyptic outcomes. 84 00:08:41,400 --> 00:08:47,400 In fact, wherever you describe this warm period, it appears to be associated with riches. 85 00:08:48,400 --> 00:08:57,400 In Europe, this was the great age of the cathedral builders, a time when, according to Chaucer, vineyards flourished even in the north of England. 86 00:08:57,400 --> 00:09:05,400 All over the city of London, there are little memories of the vineyards that grew in the medieval warm period. 87 00:09:05,400 --> 00:09:09,400 So this was a wonderfully rich time. 88 00:09:09,400 --> 00:09:15,400 And this little church, in a sense, symbolises it, because it comes from a period of great wealth. 89 00:09:16,400 --> 00:09:34,400 Going back in time further still, before the medieval warm period, we find more warm spells, including a very prolonged period during the Bronze Age, known to geologists as the Holocene Maximum, when temperatures were significantly higher than they are now for more than three millennia. 90 00:09:34,400 --> 00:09:41,400 If we go back 8,000 years in the Holocene period, our current inner glacial, it was much warmer than it is today. 91 00:09:41,400 --> 00:09:45,400 Now the polar bears obviously survived that period. They're with us today. 92 00:09:45,400 --> 00:09:53,400 They are very adaptable, and these warm periods in the past, what we call hypsothermals, pose no problem for them. 93 00:09:54,400 --> 00:10:01,400 Climate variation in the past is clearly natural. So why do we think it's any different today? 94 00:10:03,400 --> 00:10:08,400 In the current alarm about global warming, the culprit is industrial society. 95 00:10:08,400 --> 00:10:15,400 Thanks to modern industry, luxuries once enjoyed exclusively by the rich are now available in abundance to ordinary people. 96 00:10:15,400 --> 00:10:24,400 Novel technologies have made life easier and richer. Modern transport and communications have made the world seem less foreign and distant. 97 00:10:24,400 --> 00:10:30,400 Industrial progress has changed our lives. But has it also changed the climate? 98 00:10:31,400 --> 00:10:38,400 According to the theory of man-made global warming, industrial growth should cause the temperature to rise. But does it? 99 00:10:39,400 --> 00:10:50,400 Anyone who goes around and says that carbon dioxide is responsible for most of the warming of the 20th century hasn't looked at the basic numbers. 100 00:10:50,400 --> 00:11:03,400 Industrial production in the early decades of the 20th century was still in its infancy, restricted to only a few countries, handicapped by war and economic depression. 101 00:11:04,400 --> 00:11:15,400 After the Second World War, things changed. Consumer goods like refrigerators and washing machines and TVs and cars began to be mass-produced for an international market. 102 00:11:15,400 --> 00:11:21,400 Historians call this global explosion of industrial activity the post-war economic boom. 103 00:11:22,400 --> 00:11:26,400 So how does the industrial story compare with the temperature record? 104 00:11:27,400 --> 00:11:33,400 Since the mid-19th century, the Earth's temperature has risen by just over half a degree Celsius. 105 00:11:34,400 --> 00:11:38,400 But this warming began long before cars and planes were even invented. 106 00:11:39,400 --> 00:11:48,400 What's more, most of the rise in temperature occurred before 1940, during a period when industrial production was relatively insignificant. 107 00:11:49,400 --> 00:11:56,400 After the Second World War, during the post-war economic boom, temperatures, in theory, should have shot up. 108 00:11:57,400 --> 00:12:02,400 But they didn't. They fell. Not for one or two years, but for four decades. 109 00:12:02,400 --> 00:12:09,400 In fact, paradoxically, it wasn't until the world economic recession in the 1970s that they stopped falling. 110 00:12:32,400 --> 00:12:39,400 If we can't say that the temperature is rapidly, but yet the temperature is decreasing, then we cannot say that CO2 and the temperature go together. 111 00:12:40,400 --> 00:12:46,400 Temperature went up significantly up to 1940, when human production of CO2 was relatively low. 112 00:12:47,400 --> 00:12:57,400 And then in the post-war years, when industry and the whole economies of the world really got going, and human production of CO2 just soared, the global temperature was going down. 113 00:12:58,400 --> 00:13:00,400 In other words, the facts didn't fit the theory. 114 00:13:02,400 --> 00:13:20,400 Just at a time when, after the Second World War, industry was booming, carbon dioxide was increasing, and yet the earth was getting cooler and starting off scares over coming ice age, it made absolutely no sense. It still doesn't make sense. 115 00:13:21,400 --> 00:13:25,400 Why do we suppose that carbon dioxide is responsible for our changing climate? 116 00:13:26,400 --> 00:13:37,400 CO2 forms only a very small part of the earth's atmosphere. In fact, we measure changes in the level of atmospheric CO2 in tens of parts per million. 117 00:13:38,400 --> 00:13:50,400 If you take CO2 as a percentage of all the gases in the atmosphere, the oxygen, the nitrogen, and argon, and so on, it's 0.054%. It's an incredibly small portion. 118 00:13:51,400 --> 00:13:58,400 And then, of course, you've got to take that portion that supposedly humans are adding, which is the focus of all the concern, and it gets even smaller. 119 00:13:59,400 --> 00:14:09,400 Although CO2 is a greenhouse gas, greenhouse gases themselves only form a small part of the atmosphere. What's more, CO2 is a relatively minor greenhouse gas. 120 00:14:10,400 --> 00:14:24,400 The atmosphere is made up of a multitude of gases, a small percentage of them we call greenhouse gases, and of that very small percentage of greenhouse gases, 95% of it is water vapor. It's the most important greenhouse gas. 121 00:14:24,400 --> 00:14:28,400 Water vapor is a greenhouse gas, by far the most important greenhouse gas. 122 00:14:29,400 --> 00:14:34,400 So is there any way of checking whether the recent warming was due to an increase in greenhouse gas? 123 00:14:35,400 --> 00:14:44,400 There is only one way to tell, and that is to look up in the sky, or a part of the sky known to scientists as the troposphere. 124 00:14:45,400 --> 00:14:56,400 If it's greenhouse warming, you get more warming in the middle of the troposphere, the first 10, 12 kilometers of the atmosphere, than you do at the surface. 125 00:14:57,400 --> 00:15:02,400 There are good theoretical reasons for that, having to do with how the greenhouse works. 126 00:15:03,400 --> 00:15:07,400 The greenhouse effect works like this. The sun sends its heat down to Earth. 127 00:15:07,400 --> 00:15:14,400 If it weren't for greenhouse gases, this solar radiation would bounce back into space, leaving the planet cold and uninhabitable. 128 00:15:15,400 --> 00:15:20,400 Greenhouse gas traps the escaping heat in the Earth's troposphere, a few miles above the surface. 129 00:15:21,400 --> 00:15:28,400 And it's here, according to the climate models, that the rate of warming should be highest, if it's greenhouse gas that's causing it. 130 00:15:29,400 --> 00:15:38,400 All the models, every one of them, calculates that the warming should be faster as you go up from the surface into the atmosphere. 131 00:15:41,400 --> 00:15:48,400 And in fact, the maximum warming over the equator should take place at an altitude of about 10 kilometers. 132 00:15:49,400 --> 00:15:55,400 A scientist largely responsible for measuring the temperature in the Earth's atmosphere is Professor John Christie. 133 00:15:56,400 --> 00:16:00,400 In 1991, he was awarded NASA's Medal for Exceptional Scientific Achievement. 134 00:16:01,400 --> 00:16:09,400 And in 1996, received a special award from the American Meteorological Society for fundamentally advancing our ability to monitor climate. 135 00:16:09,400 --> 00:16:14,400 He was a lead author on the UN's Intergovernmental Panel on Climate Change, or IPCC. 136 00:16:19,400 --> 00:16:25,400 There are two ways to take the temperature in the Earth's atmosphere, satellites and weather balloons. 137 00:16:28,400 --> 00:16:32,400 What we found consistently is that in a... 138 00:16:32,400 --> 00:16:39,400 Great part of the planet, that the bulk of the atmosphere is not warming as much as we see at the surface in this region. 139 00:16:39,400 --> 00:16:44,400 And that's a real head-scratcher for us, because the theory is pretty straightforward. 140 00:16:45,400 --> 00:16:50,400 And the theory says that if the surface warms, the upper atmosphere should warm rapidly. 141 00:16:51,400 --> 00:16:58,400 The rise in temperature of that part of the atmosphere is not very dry, and that's why we're not seeing any warming. 142 00:16:58,400 --> 00:17:09,400 The rise in temperature of that part of the atmosphere is not very dramatic at all, and really does not match the theory that climate models are expressing at this point. 143 00:17:10,400 --> 00:17:19,400 One of the problems that is plaguing the models is that they predict that as you go up through the atmosphere, except in the polar regions, that the rate of warming increases. 144 00:17:19,400 --> 00:17:29,400 And it's quite clear from two datasets, not just satellite data, which everybody talks about, but from weather balloon data, that you don't see that effect. 145 00:17:30,400 --> 00:17:37,400 In fact, it looks like the surface temperatures are warming slightly more than the upper air temperatures. That's a big difference. 146 00:17:38,400 --> 00:17:46,400 That data gives you a handle on the fact that what you're seeing is warming that probably is not due to greenhouse gases. 147 00:17:46,400 --> 00:17:56,400 That is, the observations do not show an increase with altitude. In fact, most observations show a slight decrease in the rate of warming with altitude. 148 00:17:57,400 --> 00:18:06,400 So in a sense, you can say that the hypothesis of man-made global warming is falsified by the evidence. 149 00:18:08,400 --> 00:18:13,400 So the recent warming of the Earth happened in the wrong place and at the wrong time. 150 00:18:13,400 --> 00:18:24,400 Most of the warming took place in the early part of the 20th century and occurred mostly at the Earth's surface, the very opposite of what should have happened according to the theory of man-made global warming. 151 00:18:26,400 --> 00:18:30,400 I am Al Gore. I used to be the next president of the United States of America. 152 00:18:32,400 --> 00:18:42,400 Former Vice President Al Gore's emotional film, An Inconvenient Truth, is regarded by many as the definitive popular presentation of the theory of man-made global warming. 153 00:18:43,400 --> 00:18:55,400 His argument rests on one all-important piece of evidence taken from ice core surveys in which scientists drill deep into the ice to look back into Earth's climate history hundreds of thousands of years. 154 00:18:56,400 --> 00:19:07,400 The first ice core survey took place in Vostok in the Antarctic. What it found, as Al Gore correctly points out, was a clear correlation between carbon dioxide and temperature. 155 00:19:08,400 --> 00:19:15,400 We're going back in time now, 650,000 years. Here's what the temperature has been on our Earth. 156 00:19:17,400 --> 00:19:22,400 Now one thing that kind of jumps out at you is, did they ever fit together? 157 00:19:23,400 --> 00:19:25,400 Most ridiculous thing I've ever heard. 158 00:19:26,400 --> 00:19:34,400 The relationship is actually very complicated, but there is one relationship that is far more powerful than all the others, and it is this. 159 00:19:34,400 --> 00:19:38,400 When there is more carbon dioxide, the temperature gets warmer. 160 00:19:39,400 --> 00:19:46,400 Al Gore says the relationship between temperature and CO2 is complicated, but he doesn't say what those complications are. 161 00:19:47,400 --> 00:19:51,400 In fact, there was something very important in the ice core data that he failed to mention. 162 00:19:52,400 --> 00:20:00,400 Professor Ian Clark is a leading Arctic paleoclimatologist who looks back into the Earth's temperature record tens of millions of years. 163 00:20:01,400 --> 00:20:07,400 When we look at climate on long scales, we're looking for geological material that actually records climate. 164 00:20:08,400 --> 00:20:17,400 If we were to take an ice sample, for example, we use isotopes to reconstruct temperature, but the atmosphere that's imprisoned in that ice, we liberate, and then we look at the CO2 content. 165 00:20:19,400 --> 00:20:25,400 Professor Clark and others have indeed discovered, as Al Gore says, a link between carbon dioxide and temperature. 166 00:20:25,400 --> 00:20:29,400 But what Al Gore doesn't say is that the link is the wrong way round. 167 00:20:30,400 --> 00:20:42,400 So here we're looking at the ice core record from Vostok, and in the red we see temperature going up from early time to later time at a very key interval when we came out of a glaciation. 168 00:20:43,400 --> 00:20:48,400 And we see the temperature going up, and then we see the CO2 coming up. 169 00:20:48,400 --> 00:20:58,400 We see the CO2 coming up. CO2 lags behind that increase. It's got an 800-year lag, so temperature is leading CO2 by 800 years. 170 00:21:00,400 --> 00:21:05,400 There have now been several major ice core surveys. Every one of them shows the same thing. 171 00:21:06,400 --> 00:21:11,400 The temperature rises or falls, and then, after a few hundred years, carbon dioxide follows. 172 00:21:12,400 --> 00:21:22,400 So obviously, carbon dioxide is not the cause of that warming. In fact, we can say that the warming produced the increase in carbon dioxide. 173 00:21:23,400 --> 00:21:30,400 CO2 clearly cannot be causing temperature changes. It's a product of temperature. It's following temperature changes. 174 00:21:31,400 --> 00:21:36,400 The ice core record goes to the very heart of the problem we have here. 175 00:21:37,400 --> 00:21:43,400 They said, if the CO2 increases in the atmosphere as a greenhouse gas, then the temperature will go up. 176 00:21:44,400 --> 00:21:56,400 But the ice core record shows exactly the opposite. So the fundamental assumption, the most fundamental assumption of the whole theory of climate change, due to humans, is shown to be wrong. 177 00:21:57,400 --> 00:22:02,400 But how can it be that higher temperatures lead to more CO2 in the atmosphere? 178 00:22:03,400 --> 00:22:11,400 To understand this, we must first restate the obvious point that carbon dioxide is a natural gas produced by all living things. 179 00:22:12,400 --> 00:22:19,400 Few things annoy me more than to hear people talking about carbon dioxide as being a pollutant. 180 00:22:20,400 --> 00:22:26,400 You're made of carbon dioxide. I'm made of carbon dioxide. Carbon dioxide is how living things grow. 181 00:22:27,400 --> 00:22:31,400 What's more, humans are not the main source of carbon dioxide. 182 00:22:32,400 --> 00:22:39,400 Humans produce a small fraction in the single digits, percentage-wise, of the CO2 that is produced in the atmosphere. 183 00:22:40,400 --> 00:22:49,400 Volcanoes produce more CO2 each year than all the factories and cars and planes and other sources of man-made carbon dioxide put together. 184 00:22:50,400 --> 00:22:59,400 More still comes from animals and bacteria, which produce about 150 gigatons of CO2 each year compared to a mere 6.5 gigatons from humans. 185 00:23:00,400 --> 00:23:06,400 An even larger source of CO2 is dying vegetation, from falling leaves, for example, in the autumn. 186 00:23:06,400 --> 00:23:10,400 But the biggest source of CO2, by far, is the oceans. 187 00:23:15,400 --> 00:23:29,400 Carl Wunsch is Professor of Oceanography at MIT. He was also Visiting Professor in Oceanography at Harvard University and University College London, and a Senior Visiting Fellow in Mathematics and Physics at the University of Cambridge. 188 00:23:30,400 --> 00:23:34,400 He is the author of four major textbooks on oceanography. 189 00:23:34,400 --> 00:23:43,400 The ocean is the major reservoir into which carbon dioxide goes when it comes out of the atmosphere or from which it is re-emitted to the atmosphere. 190 00:23:44,400 --> 00:23:49,400 If you heat the surface of the ocean, it tends to emit carbon dioxide. 191 00:23:50,400 --> 00:23:57,400 So similarly, if you cool the ocean surface, the ocean can dissolve more carbon dioxide. 192 00:24:04,400 --> 00:24:10,400 So the warmer the oceans, the more carbon dioxide they produce, and the cooler they are, the more they suck in. 193 00:24:11,400 --> 00:24:19,400 But why is there a time lag of hundreds of years between a change in temperature and a change in the amount of carbon dioxide going into or out of the sea? 194 00:24:20,400 --> 00:24:28,400 The reason is that oceans are so big and so deep, they take literally hundreds of years to warm up and cool down. 195 00:24:28,400 --> 00:24:34,400 This time lag means the oceans have what scientists call a memory of temperature changes. 196 00:24:35,400 --> 00:24:42,400 The ocean has a memory of past events running out as far as 10,000 years. 197 00:24:43,400 --> 00:24:52,400 So, for example, if somebody says, oh, I'm seeing changes in the North Atlantic, this must mean that the climate system is changing. 198 00:24:52,400 --> 00:25:02,400 It may only mean that something happened in a remote part of the ocean decades or hundreds of years ago whose effects are now beginning to show up in the North Atlantic. 199 00:25:03,400 --> 00:25:07,400 The current warming began long before people had cars or electric lights. 200 00:25:08,400 --> 00:25:12,400 In the past 150 years, the temperature has risen just over half a degree Celsius. 201 00:25:13,400 --> 00:25:16,400 But most of that rise occurred before 1940. 202 00:25:17,400 --> 00:25:22,400 Since that time, the temperature has fallen for four decades and risen for three. 203 00:25:23,400 --> 00:25:30,400 There is no evidence at all from Earth's long climate history that carbon dioxide has ever determined global temperatures. 204 00:25:31,400 --> 00:25:35,400 But if CO2 doesn't drive Earth's climate, what does? 205 00:25:35,400 --> 00:25:42,400 The common belief that carbon dioxide is driving climate change is at odds with much of the available scientific data. 206 00:25:43,400 --> 00:25:49,400 Data from weather balloons and satellites, from ice core surveys and from the historical temperature records. 207 00:25:51,400 --> 00:25:55,400 But if CO2 isn't driving climate, what is? 208 00:25:55,400 --> 00:26:03,400 Isn't it bizarre to think that it's humans, you know, when we're filling up our car, turning on our lights, that we're the ones controlling climate? 209 00:26:04,400 --> 00:26:08,400 Just look in the sky. Look at that massive thing, the sun. 210 00:26:10,400 --> 00:26:15,400 Even humans at our present six and a half billion are minute relative to that. 211 00:26:15,400 --> 00:26:21,400 In the late 1980s, solar physicist Piers Corbin decided to try a radically new way of forecasting the weather. 212 00:26:22,400 --> 00:26:29,400 Despite the huge resources of the official Met Office, Corbin's new technique consistently produced more accurate results. 213 00:26:30,400 --> 00:26:40,920 He was hailed in the national press as a super weather expert, but he was also a very good 214 00:26:40,920 --> 00:26:43,920 The secret of his success was the sun. 215 00:26:44,920 --> 00:26:52,920 The origin of our solar weather technique of long range forecasting came originally from study of sunspots and a desire to predict those. 216 00:26:53,920 --> 00:26:59,920 And then I realised it was actually much more interesting to use the sun to predict the weather. 217 00:27:10,920 --> 00:27:17,920 Sunspots, we now know, are intense magnetic fields which appear at times of higher solar activity. 218 00:27:18,920 --> 00:27:30,920 But for many hundreds of years, long before this was properly understood, astronomers around the world used to count the number of sunspots in the belief that more spots heralded warmer weather. 219 00:27:31,920 --> 00:27:39,920 In 1893, the British astronomer Edward Maunder observed that during the Little Ice Age, there were barely any spots visible on the sun. 220 00:27:40,920 --> 00:27:44,920 A period of solar inactivity which became known as the Maunder minimum. 221 00:27:45,920 --> 00:27:49,920 But how reliable are sunspots as an indicator of the weather? 222 00:27:49,920 --> 00:27:56,920 I decided to test it by gambling on the weather through William Hill against what the Met Office said was a normal expectation. 223 00:27:57,920 --> 00:28:01,920 And I won money month after month after month after month. 224 00:28:02,920 --> 00:28:07,920 Last winter the Met Office said it could be or would be an exceptionally cold winter. 225 00:28:08,920 --> 00:28:11,920 We said no, that is nonsense, it's going to be very close to normal. 226 00:28:12,920 --> 00:28:16,920 And we specifically said when it would be cold, i.e. after winter. 227 00:28:16,920 --> 00:28:20,920 And we specifically said when it would be cold, i.e. after Christmas and February. 228 00:28:21,920 --> 00:28:22,920 We were right, they were wrong. 229 00:28:23,920 --> 00:28:33,920 In 1991, senior scientists at the Danish Meteorological Institute decided to compile a record of sunspots in the 20th century and compare it with the temperature record. 230 00:28:34,920 --> 00:28:42,920 What they found was an incredibly close correlation between what the sun was doing and changes in temperature on Earth. 231 00:28:43,920 --> 00:28:53,920 Solar activity they found rose sharply to 1940, fell back for four decades until the 1970s and then rose again after that. 232 00:28:57,920 --> 00:29:08,920 When we saw this correlation between the temperature and solar activity or sunspot cyclings, then people said to us, okay, it can be just a coincidence. 233 00:29:08,920 --> 00:29:12,920 So how can we prove that it's not just a coincidence? 234 00:29:13,920 --> 00:29:17,920 Well, one obvious thing is to have a longer time series or different time series. 235 00:29:18,920 --> 00:29:19,920 Then we went back in time. 236 00:29:20,920 --> 00:29:30,920 So Professor Fries Christensen and his colleagues examined 400 years of astronomical records to compare sunspot activity against temperature variation. 237 00:29:31,920 --> 00:29:38,920 Once again, they found that variations in solar activity were intimately linked to temperature variation on Earth. 238 00:29:39,920 --> 00:29:45,920 It was the sun, it seemed, not carbon dioxide or anything else that was driving changes in the climate. 239 00:29:47,920 --> 00:29:48,920 In a way, it's not surprising. 240 00:29:49,920 --> 00:29:52,920 The sun affects us directly, of course, when it sends down its heat. 241 00:29:53,920 --> 00:29:58,920 But we now know the sun also affects us indirectly through clouds. 242 00:30:00,920 --> 00:30:02,920 Clouds have a powerful cooling effect. 243 00:30:03,920 --> 00:30:04,920 But how are they formed? 244 00:30:05,920 --> 00:30:11,920 In the early 20th century, scientists discovered that the Earth was constantly being bombarded by subatomic particles. 245 00:30:12,920 --> 00:30:20,920 These particles, which they called cosmic rays, originated, it was believed, from exploding supernovae far beyond our solar system. 246 00:30:21,920 --> 00:30:29,920 When the particles coming down meet water vapour rising up from the sea, they form water droplets and make clouds. 247 00:30:30,920 --> 00:30:37,920 But when the sun is more active and the solar wind is strong, fewer particles get through and fewer clouds are formed. 248 00:30:41,920 --> 00:30:58,920 Just how powerful this effect was became clear only recently when an astrophysicist, Professor Neher Shaviv, decided to compare his own record of cloud forming cosmic rays with the temperature record created by a geologist, Professor Jan Weitzer, going back 600 million years. 249 00:31:00,920 --> 00:31:07,920 What they found was that when cosmic rays went up, the temperature went down. When cosmic rays went down, the temperature went up. 250 00:31:08,920 --> 00:31:14,920 Clouds and the Earth's climate were very closely linked, to see how close you just flip the lines. 251 00:31:15,920 --> 00:31:20,920 We just compared the graphs, just put them one upon the other, and it was just amazing. 252 00:31:21,920 --> 00:31:25,920 Jan Weiser looked at me and said, you know, we have very explosive data here. 253 00:31:25,920 --> 00:31:34,920 I've never seen such vastly different records coming together so beautifully to show really what was happening over that long period of time. 254 00:31:35,920 --> 00:31:48,920 The climate was controlled by the clouds. The clouds were controlled by cosmic rays. And the cosmic rays were controlled by the sun. It all came down to the sun. 255 00:31:48,920 --> 00:32:01,920 If you had X-ray eyes, what appears as a nice friendly yellow ball would appear like a raging tiger. 256 00:32:01,920 --> 00:32:10,920 The sun is an incredibly violent beast. And it's throwing out great explosions and puffs of gas. 257 00:32:10,920 --> 00:32:21,920 The sun is an incredibly violent beast. And it's throwing out great explosions and puffs of gas. 258 00:32:21,920 --> 00:32:27,920 An endless solar wind that's forever rushing past the Earth. 259 00:32:28,920 --> 00:32:33,920 We're in a certain sense inside the atmosphere of the sun. 260 00:32:34,920 --> 00:32:40,920 The intensity of its magnetic field more than doubled during the 20th century. 261 00:32:40,920 --> 00:32:50,920 In 2005, astrophysicists from Harvard University published the following graph in the official Journal of the American Geophysical Union. 262 00:32:51,920 --> 00:32:56,920 The blue line represents temperature change in the Arctic over the past hundred years. 263 00:32:57,920 --> 00:33:01,920 And here is the rise in carbon dioxide over the same period. 264 00:33:02,920 --> 00:33:07,920 The two are not obviously connected. But now look again at the temperature record. 265 00:33:07,920 --> 00:33:20,920 And at this red line, which depicts variations in solar activity over the past century as recorded independently by scientists from NASA and America's National Oceanic and Atmospheric Administration. 266 00:33:21,920 --> 00:33:31,920 Solar activity over the last hundred years, over the last several hundred years, correlates very nicely on a decadal basis with sea ice and Arctic temperatures. 267 00:33:32,920 --> 00:33:38,920 To the Harvard astrophysicists and many other scientists, the conclusion is inescapable. 268 00:33:39,920 --> 00:33:43,920 The sun is driving climate change. CO2 is irrelevant. 269 00:33:44,920 --> 00:33:51,920 But why, if this is so, are we bombarded day after day with news items about man-made global warming? 270 00:33:52,920 --> 00:33:57,920 Why do so many people in the media and elsewhere regard it as an undisputed fact? 271 00:33:58,920 --> 00:34:04,920 To understand the power of global warming theory, we must tell the story of how it came about. 272 00:34:11,920 --> 00:34:15,920 The weather satellite depicts a planet that grieves for its lost harvests. 273 00:34:16,920 --> 00:34:20,920 Doom-laden predictions about climate change are not new. 274 00:34:21,920 --> 00:34:26,920 In 1974, the BBC warned us of impending disasters, which might seem strangely familiar. 275 00:34:38,920 --> 00:34:40,920 And what was going to be the cause of these disasters? 276 00:34:41,920 --> 00:34:45,920 The man behind the series was former New Scientist editor Nigel Calder. 277 00:34:50,920 --> 00:34:55,920 He had the opinion of the time which was global cooling and the threat of a new ice age. 278 00:34:56,920 --> 00:34:58,920 Nature's ice dwarfs us. 279 00:34:59,920 --> 00:35:05,920 After four decades of falling temperatures, experts warned that a cooler world would have catastrophic consequences. 280 00:35:06,920 --> 00:35:13,920 There's the ever-present threat of a big freeze. Will a new ice age claim our lands and bury our northern cities? 281 00:35:14,920 --> 00:35:18,920 But amid the doom and gloom, there was one voice of hope. 282 00:35:19,920 --> 00:35:27,920 A Swedish scientist called Bert Bollin tentatively suggested that man-made carbon dioxide might help to warm the world, although he wasn't sure. 283 00:35:28,920 --> 00:35:31,920 And there's a lot of oil and there are vast amounts of coal left. 284 00:35:32,920 --> 00:35:34,920 We seem to be burning it with an ever-increasing rate. 285 00:35:35,920 --> 00:35:41,920 And if we go on doing this, in about 50 years' time, the climate may be a few degrees warmer than today. 286 00:35:41,920 --> 00:35:43,920 We just don't know. 287 00:35:44,920 --> 00:35:53,920 We were also the first to put Bert Bollin of Sweden on international television talking about the dangers of carbon dioxide. 288 00:35:54,920 --> 00:36:01,920 And I remember being bitterly criticised by top experts for indulging him in his fantasy. 289 00:36:02,920 --> 00:36:09,920 At the height of the cooling scare in the 70s, Bert Bollin's eccentric theory of man-made global warming seemed absurd. 290 00:36:09,920 --> 00:36:11,920 Two things happened to change that. 291 00:36:12,920 --> 00:36:18,920 First, temperatures started to rise. And second, the miners went on strike. 292 00:36:24,920 --> 00:36:27,920 To Margaret Thatcher, energy was a political problem. 293 00:36:28,920 --> 00:36:35,920 In the early 70s, the oil crisis had plunged the world into recession and the miners had brought down Ted Heath's Conservative government. 294 00:36:36,920 --> 00:36:42,920 Mrs Thatcher was determined the same would not happen to her. She set out to break their power. 295 00:36:43,920 --> 00:36:54,920 What we have seen in this country is the emergence of an organised revolutionary minority who are prepared to exploit industrial disputes, 296 00:36:55,920 --> 00:37:02,920 but whose real aim is the breakdown of law and order and the destruction of democratic parliamentary government. 297 00:37:03,920 --> 00:37:09,920 The politicisation of the subject started with Margaret Thatcher. 298 00:37:10,920 --> 00:37:16,920 She was very concerned always, I remember when I was Secretary of State for Energy, to promote nuclear power, 299 00:37:17,920 --> 00:37:24,920 long before the issue of climate change came up, because she was concerned about energy security. 300 00:37:25,920 --> 00:37:28,920 And she didn't trust the Middle East and she didn't trust the National Union of Mineworkers. 301 00:37:29,920 --> 00:37:36,920 So she didn't trust oil and she didn't trust coal. So therefore she felt we really had to push ahead with nuclear power. 302 00:37:37,920 --> 00:37:43,920 And then when the climate change, global warming thing came up, she felt, well this is great, this is another argument, 303 00:37:44,920 --> 00:37:48,920 because it doesn't have any carbon dioxide emissions, this is another argument why you should go for nuclear. 304 00:37:49,920 --> 00:37:52,920 And that is what she was really largely saying. It's been misrepresented since then. 305 00:37:53,920 --> 00:37:57,920 And so she said to the scientists, she went to the Royal Society and she said, 306 00:37:58,920 --> 00:38:05,920 there's money on the table for you to prove this stuff. So of course they went away and did that. 307 00:38:06,920 --> 00:38:12,920 Inevitably, the moment politicians put their weight behind something and attach their name to it in some ways, 308 00:38:13,920 --> 00:38:15,920 of course, money will flow, that's the way it goes. 309 00:38:15,920 --> 00:38:22,920 And inevitably research, development institutions started to bubble up, put it that way, 310 00:38:23,920 --> 00:38:30,920 which were going to be researching climate, but with a particular emphasis on the relationship between carbon dioxide and temperature. 311 00:38:32,920 --> 00:38:37,920 At the request of Mrs Thatcher, the UK Met Office set up a climate modelling unit, 312 00:38:37,920 --> 00:38:45,920 which provided the basis for a new international committee called the Intergovernmental Panel on Climate Change, or IPCC. 313 00:38:46,920 --> 00:38:54,920 They came out with the first big report, which predicted climatic disaster as a result of global warming. 314 00:38:55,920 --> 00:39:01,920 I remember going to the scientific press conference and being amazed by two things. 315 00:39:02,920 --> 00:39:08,920 First, the simplicity and eloquence of the message and the vigor with which it was delivered. 316 00:39:09,920 --> 00:39:17,920 And secondly, the total disregard of all climate science up till that time, 317 00:39:18,920 --> 00:39:29,920 including, incidentally, the role of the sun, which had been the subject of a major meeting at the Royal Society just a few months earlier. 318 00:39:30,920 --> 00:39:37,920 But the new emphasis on man-made carbon dioxide as a possible environmental problem didn't just appeal to Mrs Thatcher. 319 00:39:39,920 --> 00:39:45,920 It was certainly something very favourable to the environmental idea, 320 00:39:46,920 --> 00:39:52,920 what I call the medieval environmentalism of let's get back to the way things were in medieval times 321 00:39:53,920 --> 00:39:55,920 and get rid of all these dreadful cars and machines. 322 00:39:55,920 --> 00:40:02,920 They loved it because carbon dioxide was for them an emblem of industrialisation. 323 00:40:03,920 --> 00:40:11,920 Well, carbon dioxide clearly is an industrial gas and tried and sort of tied in with economic growth, 324 00:40:12,920 --> 00:40:18,920 with transportation in cars, with what we call civilisation. 325 00:40:18,920 --> 00:40:25,920 And there are forces in the environmental movement that are simply against economic growth. They think that's bad. 326 00:40:26,920 --> 00:40:32,920 It could be used to legitimise a whole suite of myths that already existed. 327 00:40:33,920 --> 00:40:41,920 Anti-car, anti-growth, anti-development and above all, anti-that great Satan, the US. 328 00:40:42,920 --> 00:40:49,920 Patrick Moore is considered one of the foremost environmentalists of his generation. He is co-founder of Greenpeace. 329 00:40:50,920 --> 00:40:56,920 The shift to climate being a major focal point came about for two very distinct reasons. 330 00:40:57,920 --> 00:41:04,920 The first reason was because by the mid-80s a majority of people now agreed with all of the reasonable things 331 00:41:05,920 --> 00:41:08,920 we in the environmental movement were saying they should do. 332 00:41:08,920 --> 00:41:13,920 Now when a majority of people agree with you, it's pretty hard to remain confrontational with them. 333 00:41:14,920 --> 00:41:20,920 And so the only way to remain anti-establishment was to adopt ever more extreme positions. 334 00:41:21,920 --> 00:41:26,920 When I left Greenpeace it was in the midst of them adopting a campaign to ban chlorine worldwide. 335 00:41:27,920 --> 00:41:31,920 Like I said, you guys, this is one of the elements in the periodic table, you know. 336 00:41:32,920 --> 00:41:35,920 I mean, I'm not sure if that's in our jurisdiction to be banning a whole element. 337 00:41:35,920 --> 00:41:42,920 The other reason that environmental extremism emerged was because world communism failed, the wall came down 338 00:41:43,920 --> 00:41:49,920 and a lot of peaceniks and political activists moved into the environmental movement bringing their neo-Marxism with them 339 00:41:50,920 --> 00:41:55,920 and learned to use green language in a very clever way to cloak agendas that actually have more to do with 340 00:41:56,920 --> 00:42:00,920 anti-capitalism and anti-globalization than they do anything with ecology or science. 341 00:42:00,920 --> 00:42:07,920 The left have been slightly disoriented by the manifest failure of socialism and indeed more so of communism 342 00:42:08,920 --> 00:42:13,920 as it was tried out and therefore they still remain as anti-capitalists as they were, 343 00:42:14,920 --> 00:42:17,920 but they have to find a new guise for their anti-capitalism. 344 00:42:18,920 --> 00:42:26,920 And it was a kind of amazing alliance from Margaret Thatcher on the right, 345 00:42:26,920 --> 00:42:39,920 through to very left-wing anti-capitalist environmentalists that created this kind of momentum behind a loony idea. 346 00:42:40,920 --> 00:42:46,920 By the early 1990s, man-made global warming was no longer a slightly eccentric theory about climate. 347 00:42:47,920 --> 00:42:51,920 It was a full-blown political campaign. It was attracting media attention. 348 00:42:51,920 --> 00:42:58,920 Prior to Bush the Elder, I think the level of funding for climate and climate-related sciences was somewhere around the order of $170 million a year, 349 00:42:59,920 --> 00:43:05,920 which was reasonable for the size of the field. It jumped to $2 billion a year, 350 00:43:06,920 --> 00:43:08,920 more than a factor of $10 billion. 351 00:43:08,920 --> 00:43:13,920 And yeah, that changed a lot. I mean, that's a lot of jobs. 352 00:43:14,920 --> 00:43:19,920 A lot of jobs. It brought a lot of new people into it who otherwise were not interested. 353 00:43:20,920 --> 00:43:25,920 So you developed whole cadres of people who's only interested in the science of climate. 354 00:43:26,920 --> 00:43:28,920 And that's what we're doing now. 355 00:43:29,920 --> 00:43:32,920 We're doing a lot of research. We're doing a lot of research. 356 00:43:32,920 --> 00:43:42,920 So you developed whole cadres of people who's only interested in the field was that there was global warming. 357 00:43:43,920 --> 00:43:47,920 If I wanted to do research on, shall we say, the squirrels of Sussex, 358 00:43:48,920 --> 00:43:53,920 what I would do, and this is any time from 1990 onwards, 359 00:43:54,920 --> 00:44:03,920 I would write my grant application saying I want to investigate the nut-gathering behavior of squirrels 360 00:44:04,920 --> 00:44:07,920 with special reference to the effects of global warming. 361 00:44:08,920 --> 00:44:13,920 And that way I get my money. If I forget to mention global warming, I might not get the money. 362 00:44:14,920 --> 00:44:22,920 There's only no question in my mind that the large amounts of money that have been fed into this particular rather small area of science 363 00:44:23,920 --> 00:44:25,920 have distorted the overall scientific effort. 364 00:44:26,920 --> 00:44:34,920 We're all competing for funds. And if your field is the focus of concern, 365 00:44:35,920 --> 00:44:39,920 you have that much less work rationalizing why your field should be funded. 366 00:44:45,920 --> 00:44:51,920 By the 1990s, tens of billions of dollars of government funding in the US, UK and elsewhere 367 00:44:51,920 --> 00:44:54,920 were being diverted into research relating to global warming. 368 00:44:55,920 --> 00:45:01,920 A large portion of those funds went into building computer models to forecast what the climate will be in the future. 369 00:45:02,920 --> 00:45:04,920 But how accurate are those models? 370 00:45:05,920 --> 00:45:10,920 Dr. Roy Spencer was senior scientist for climate studies at NASA's Marshall Space Flight Center. 371 00:45:11,920 --> 00:45:17,920 He has been awarded medals for exceptional scientific achievement from both NASA and the American Meteorological Society. 372 00:45:18,920 --> 00:45:23,920 Climate models are only as good as the assumptions that go into them, and they have hundreds of assumptions. 373 00:45:24,920 --> 00:45:27,920 All it takes is one assumption to be wrong for the forecast to be way off. 374 00:45:28,920 --> 00:45:34,920 Climate forecasts are not new, but in the past scientists were more modest about their ability to predict the weather. 375 00:45:35,920 --> 00:45:40,920 Any attempt at forecasting changes of climate meets skepticism from the men who model the weather by computer. 376 00:45:41,920 --> 00:45:49,920 In making decisions which affect people, a bad prediction as to what the climate of the future will be can be far worse than none at all. 377 00:45:50,920 --> 00:45:56,920 I'm afraid that our understanding of the complex weather machine is not yet good enough to make a reliable statement of the future. 378 00:46:01,920 --> 00:46:08,920 All models assume that man-made CO2 is the main cause of climate change, rather than the sun or the clouds. 379 00:46:10,920 --> 00:46:16,920 The analogy I use is like my car is not running very well, so I'm going to ignore the engine, which is the sun, 380 00:46:17,920 --> 00:46:23,920 and I'm going to ignore the transmission, which is the water vapor, and I'm going to look at one nut on the right rear wheel, which is the human-produced CO2. 381 00:46:24,920 --> 00:46:27,920 It's that, the science is that bad. 382 00:46:29,920 --> 00:46:38,920 If you haven't understood the climate system, if you haven't understood all the components, the cosmic rays, the solar, the CO2, 383 00:46:38,920 --> 00:46:46,920 the water vapor, the clouds, and put it all together, if you haven't got all that, then your model isn't worth anything. 384 00:46:47,920 --> 00:46:56,920 The range of climate forecasts varies greatly. These variations are produced by subtly altering the assumptions upon which the models are based. 385 00:46:57,920 --> 00:47:04,920 The models are so complicated you can often adjust them in such a way that they do something very exciting. 386 00:47:05,920 --> 00:47:12,920 I've worked with modelers, I've done modelling, and with a mathematical model and you tweak parameters, you can model anything. 387 00:47:13,920 --> 00:47:16,920 You can make it warmer, you can make it get colder by changing things. 388 00:47:19,920 --> 00:47:30,920 Since all the models assume that man-made CO2 causes warming, one obvious way to produce a more impressive forecast is to increase the amount of imagined man-made CO2 going into the atmosphere. 389 00:47:31,920 --> 00:47:43,920 We put an increase in carbon dioxide in them that is 1% per year. It's been 0.49% per year for the last 10 years, 0.42 for the 10 years before that, and 0.43 for the 10 years before that. 390 00:47:44,920 --> 00:47:51,920 So the models have twice as much greenhouse warming radiation going in them as is known to be happening. 391 00:47:52,920 --> 00:47:55,920 It shouldn't shock you that they predict more warming than is occurring. 392 00:48:00,920 --> 00:48:04,920 Models predict what the temperature might be in 50 or 100 years' time. 393 00:48:05,920 --> 00:48:12,920 It is one of their peculiar features that long-range climate forecasts are only proved wrong long after people have forgotten about them. 394 00:48:13,920 --> 00:48:23,920 As a result, there is a danger, according to Professor Carl Wunsch, that modelers will be less concerned in producing a forecast that is accurate than one that is interesting. 395 00:48:24,920 --> 00:48:27,920 Even within the scientific community, you see it's a problem. 396 00:48:28,920 --> 00:48:39,920 If I run a complicated model and I do something to it, like melt a lot of ice into the ocean, and nothing happens, it's not likely to get printed. 397 00:48:40,920 --> 00:48:51,920 But if I run the same model and I adjust it in such a way that something dramatic happens to the ocean circulation, like the heat transport turns off, it will be published. 398 00:48:51,920 --> 00:48:55,920 People say this is very exciting. It will even get picked up by the media. 399 00:48:56,920 --> 00:49:06,920 So there is a bias, there's a very powerful bias within the media and within the science community itself, toward results which are dramatizable. 400 00:49:08,920 --> 00:49:15,920 The Earth freezes over. That's a much more interesting story than saying, well, you know, it fluctuates around. 401 00:49:15,920 --> 00:49:22,920 Sometimes the mass flux goes up by 10 percent, sometimes it goes down by 20 percent, but eventually it comes back. 402 00:49:23,920 --> 00:49:27,920 Well, you know, which would you do a story on? I mean, that's what it's about. 403 00:49:29,920 --> 00:49:37,920 To the untrained eye, computer models look impressive, and they give often wild speculation about the climate the appearance of rigorous science. 404 00:49:38,920 --> 00:49:42,920 They also provide an endless source of spectacular stories for the media. 405 00:49:42,920 --> 00:49:53,920 The thing that has amazed me as a lifelong journalist is how the most elementary principles of journalism seem to have been abandoned on this subject. 406 00:49:54,920 --> 00:49:59,920 In fact, the theory of man-made global warming has spawned an entirely new branch of journalism. 407 00:50:00,920 --> 00:50:05,920 You've got a whole new generation of reporters, environmental journalists. 408 00:50:06,920 --> 00:50:15,920 Now, if you're an environmental journalist, and if the global warming story goes in the trash can, so does your job. 409 00:50:16,920 --> 00:50:32,920 It really is that crude. And the reporting has to get more and more hysterical because there are still, fortunately, a few hardened news editors around who will say, you know, this is what you were saying five years ago. 410 00:50:32,920 --> 00:50:39,920 Ah, but now it's much, much worse. You know, there's going to be 10 feet of sea level rise by next Tuesday or something. 411 00:50:40,920 --> 00:50:44,920 They have to keep on getting shriller and shriller and shriller. 412 00:50:46,920 --> 00:50:54,920 It is now common in the media to lay the blame for every storm or hurricane on global warming. But is there any scientific basis for this? 413 00:50:55,920 --> 00:51:09,920 This is purely propaganda. Every textbook in meteorology is telling you the main source of weather disturbances is the temperature difference between the tropics and the pole. 414 00:51:10,920 --> 00:51:20,920 And we're told in a warmer world, this difference will get less. Now, that would tell you, you will have less storminess, you'll have less variability. 415 00:51:21,920 --> 00:51:26,920 But for some reason, that isn't considered catastrophic. So you're told the opposite. 416 00:51:27,920 --> 00:51:38,920 News reports frequently argue that even a mild increase in global temperature could lead to a catastrophic melting of the polar ice caps. But what does Earth's climate history tell us? 417 00:51:39,920 --> 00:51:46,920 We happen to have temperature records of Greenland that go back thousands of years. Greenland has been much warmer. 418 00:51:47,920 --> 00:51:54,920 Just a thousand years ago, Greenland was warmer than it is today. Yet it didn't have a dramatic melting event. 419 00:51:55,920 --> 00:52:03,920 Even if we talk about something like permafrost, a great deal of the permafrost, that icy layer under the forests of Russia, for example, 420 00:52:03,920 --> 00:52:08,920 seven or eight thousand years ago, melted far more than we're having any evidence about it melting now. 421 00:52:09,920 --> 00:52:14,920 So in other words, this is a historical pattern again, but the world didn't come to a crunching halt because of it. 422 00:52:16,920 --> 00:52:22,920 Professor Sionishi Akasofu is head of the International Arctic Research Centre in Alaska. 423 00:52:23,920 --> 00:52:27,920 The IARC is the world's leading Arctic Research Institute. 424 00:52:27,920 --> 00:52:34,920 Professor Akasofu insists that over time the ice caps are always naturally expanding and contracting. 425 00:52:35,920 --> 00:52:42,920 There are reports from time to time of big chunk of ice break away from the Antarctic continent. 426 00:52:44,920 --> 00:52:56,920 Those must have been happening all the time. But because now we have a satellite that can detect those, that's why they become news. 427 00:52:57,920 --> 00:53:07,920 This data from NASA's meteorological satellites shows the huge natural expansion and contraction of the polar sea ice taking place in the 1990s. 428 00:53:08,920 --> 00:53:16,920 All the TV programmes that relate to global warming show a big chunk of ice falling from the edge of the glaciers. 429 00:53:17,920 --> 00:53:20,920 But people forget that ice is always moving. 430 00:53:21,920 --> 00:53:26,920 News reports frequently show images of ice breaking from the edge of the Arctic. 431 00:53:27,920 --> 00:53:33,920 What they don't say is that this is as ordinary an event in the Arctic as falling leaves on an English autumn day. 432 00:53:34,920 --> 00:53:40,920 They ask me, did you see ice falling from the edge of the glaciers? Yes. 433 00:53:41,920 --> 00:53:44,920 That's the spring break up. That's happened every year. 434 00:53:44,920 --> 00:53:54,920 Press come to us all the time, you know, I want to see something, the greenhouse disaster. I say there's none. 435 00:53:56,920 --> 00:54:01,920 Alarming television programmes raise the fearful prospect of vast tidal waves flooding Britain. 436 00:54:02,920 --> 00:54:05,920 But what causes the sea level to change and how fast does it happen? 437 00:54:06,920 --> 00:54:11,920 Sea level changes over the world in general are governed fundamentally by two factors. 438 00:54:11,920 --> 00:54:18,920 What we would call local factors, the relationship of the sea to the land, which often by the way is to do with the land rising or falling, 439 00:54:18,920 --> 00:54:20,920 than anything to do with the sea. 440 00:54:20,920 --> 00:54:29,920 But if you're talking about what we call eustatic changes of sea, worldwide changes of sea, that's through the thermal expansion of the oceans, 441 00:54:29,920 --> 00:54:34,920 nothing to do with melting ice. And that's an enormously slow and long process. 442 00:54:34,920 --> 00:54:38,920 People say, oh, I see the ocean doing this last year. 443 00:54:38,920 --> 00:54:43,920 That means that something changed in the atmosphere last year. 444 00:54:43,920 --> 00:54:45,920 And this is not necessarily true at all. 445 00:54:45,920 --> 00:54:57,920 In fact, it's actually quite unlikely because it can take hundreds to thousands of years for the deep ocean to respond to forces and changes that are taking place at the surface. 446 00:54:57,920 --> 00:55:07,920 It is also suggested that even a mild rise in temperature will lead to the spread northward of deadly insect borne tropical diseases like malaria. 447 00:55:07,920 --> 00:55:09,920 But is this true? 448 00:55:10,920 --> 00:55:18,920 Professor Paul Reiter of the Pasteur Institute in Paris is recognised as one of the world's leading experts on malaria and other insect borne diseases. 449 00:55:18,920 --> 00:55:22,920 He is a member of the World Health Organisation Expert Advisory Board. 450 00:55:23,920 --> 00:55:29,920 He was chairman of the American Committee of Medical Entomology of the American Society for Tropical Medicine 451 00:55:29,920 --> 00:55:36,920 and lead author on the health section of the US National Assessment of the Potential Consequences of Climate Variability. 452 00:55:36,920 --> 00:55:42,920 As Professor Reiter is eager to point out, mosquitoes thrive in very cold temperatures. 453 00:55:42,920 --> 00:55:46,920 Mosquitoes are not specifically tropical mosquitoes. 454 00:55:46,920 --> 00:55:49,920 Most people will realise that in temperate regions there are mosquitoes. 455 00:55:49,920 --> 00:55:54,920 In fact, mosquitoes are extremely abundant in the Arctic. 456 00:55:54,920 --> 00:56:00,920 The most devastating epidemic of malaria was in the Soviet Union in the 1920s. 457 00:56:00,920 --> 00:56:06,920 There were something like 13 million cases a year and something like 600,000 deaths. 458 00:56:06,920 --> 00:56:12,920 A tremendous catastrophe that reached up to the Arctic and the Arctic was the most devastating. 459 00:56:13,920 --> 00:56:17,920 A tremendous catastrophe that reached up to the Arctic Circle. 460 00:56:17,920 --> 00:56:21,920 Archangel had 30,000 cases and about 10,000 deaths. 461 00:56:21,920 --> 00:56:23,920 So it's not a tropical disease. 462 00:56:23,920 --> 00:56:31,920 Yet these people in the global warming fraternity invent the idea that malaria will move northwards. 463 00:56:32,920 --> 00:56:36,920 Climate scare stories cannot be blamed solely on sloppy or biased journalism. 464 00:56:37,920 --> 00:56:46,920 According to Professor Reiter, hysterical alarms have been encouraged by the reports of the United Nations Intergovernmental Panel on Climate Change or IPCC. 465 00:56:46,920 --> 00:56:50,920 On the spread of malaria, the IPCC warns us that... 466 00:56:58,920 --> 00:57:01,920 According to Professor Reiter, this is clearly untrue. 467 00:57:01,920 --> 00:57:09,920 I was horrified to read the second and the third assessment reports because there was so much misinformation 468 00:57:09,920 --> 00:57:18,920 without any kind of recourse or virtually without mention of the scientific literature, the truly scientific literature, 469 00:57:18,920 --> 00:57:21,920 the literature by specialists in those fields. 470 00:57:21,920 --> 00:57:28,920 In a letter to the Wall Street Journal, Professor Frederick Sites, former president of America's National Academy of Sciences, 471 00:57:28,920 --> 00:57:32,920 revealed that IPCC officials had censored the comments of scientists. 472 00:57:32,920 --> 00:57:34,920 He said that... 473 00:57:34,920 --> 00:57:38,920 This report is not the version that was approved by the contributing scientists. 474 00:57:38,920 --> 00:57:42,920 At least 15 key sections of the science chapter had been deleted. 475 00:57:42,920 --> 00:57:44,920 These included statements like... 476 00:57:59,920 --> 00:58:01,920 Professor Sites concluded... 477 00:58:10,920 --> 00:58:18,920 In its reply, the IPCC did not deny making these deletions, but it said there was no dishonesty or bias in the report 478 00:58:18,920 --> 00:58:22,920 and that uncertainties about the cause of global warming had been included. 479 00:58:23,920 --> 00:58:31,920 The changes had been made, it said, in response to comments from governments, individual scientists and non-governmental organisations. 480 00:58:31,920 --> 00:58:35,920 When I resigned from the IPCC, I thought that was the end of it. 481 00:58:35,920 --> 00:58:41,920 But when I saw the final draft, my name was still there, so I asked for it to be removed. 482 00:58:41,920 --> 00:58:45,920 Well, they told me that I had contributed, so it would remain there. 483 00:58:45,920 --> 00:58:49,920 So I said, no, I haven't contributed because they haven't listened to anything I've said. 484 00:58:49,920 --> 00:58:51,920 So in the end, it was quite a battle. 485 00:58:51,920 --> 00:58:55,920 But finally, I threatened legal action against them and they removed my name. 486 00:58:55,920 --> 00:58:57,920 And I think this happens a great deal. 487 00:58:57,920 --> 00:59:05,920 Those people who are specialists but don't agree with the polemic and resign, and there have been a number that I know of, 488 00:59:05,920 --> 00:59:12,920 they are simply put on the author list and become part of this 2,500 of the world's top scientists. 489 00:59:12,920 --> 00:59:17,920 Research relating to man-made global warming is now one of the best-funded areas of science. 490 00:59:17,920 --> 00:59:21,920 The US government alone spends more than $4 billion a year. 491 00:59:21,920 --> 00:59:28,920 According to NASA climatologist Roy Spencer, scientists who speak out against man-made global warming have a lot to lose. 492 00:59:28,920 --> 00:59:35,920 It's generally harder to get research proposals funded because of the stands that we've taken publicly. 493 00:59:35,920 --> 00:59:41,920 And you'll find very few of us that are willing to take a public stand because it does cut into their research funding. 494 00:59:42,920 --> 00:59:51,920 It is a common prejudice that scientists who do not agree with the theory of man-made global warming must be being paid by private industry to tell lies. 495 00:59:51,920 --> 00:59:55,920 I get it all the time. You must be in the pay of the multinationals. 496 00:59:55,920 --> 01:00:00:00,920 Sadly, like most of the scientists you'll talk to, I haven't seen a penny from the multinationals. 497 01:00:00,920 --> 01:00:02,920 I'm always accused of being paid by the oil and gas companies. 498 01:00:02,920 --> 01:00:05,920 I've never received a nickel from the oil and gas companies. 499 01:00:05,920 --> 01:00:08,920 I joke about it, I wish they would pay me, then I could afford their product. 500 01:00:08,920 --> 01:00:15,920 Whenever anybody says that I'm in the pay of an oil company, I say my bank manager would wish. 501 01:00:17,920 --> 01:00:21,920 There is almost no private sector investment in climatology. 502 01:00:21,920 --> 01:00:29,920 And yet, to be involved in any research project which involves an industry grant, no matter how small, can spell ruin to a scientist's reputation. 503 01:00:29,920 --> 01:00:32,920 Modern technology fuelled by greenhouse gases. 504 01:00:33,920 --> 01:00:38,920 Patrick Michaels is Professor of Environmental Sciences at the University of Virginia. 505 01:00:38,920 --> 01:00:43,920 He was Chair of the Committee on Applied Climatology at the American Meteorological Society, 506 01:00:43,920 --> 01:00:46,920 President of the American Association of State Climatologists, 507 01:00:46,920 --> 01:00:53,920 the author of three books on meteorology, and an author and reviewer on the UN's Intergovernmental Panel on Climate Change. 508 01:00:54,920 --> 01:00:58,920 But when he conducted research which was part-funded by the coal industry, 509 01:00:58,920 --> 01:01:02,920 he found himself among those under attack from climate campaigners. 510 01:01:02,920 --> 01:01:12,920 British-based corporations are some of the worst climate criminals on the planet. 511 01:01:12,920 --> 01:01:16,920 Shell is based in the UK, right here in London. 512 01:01:16,920 --> 01:01:24,920 We have the right and the duty to take it back into public ownership, dismantle it, break it up, and send its managers to rehabilitation training. 513 01:01:24,920 --> 01:01:29,920 But reasoned debate is not the only casualty in the global warming alarm, 514 01:01:29,920 --> 01:01:34,920 as international public policy bears down on industrial emissions of carbon dioxide, 515 01:01:34,920 --> 01:01:39,920 the developing world is coming under intense pressure not to develop. 516 01:01:42,920 --> 01:01:48,920 I'm no expert on climate change, I'm no scientist, and what I'm going to say next is a great big turn-off. 517 01:01:48,920 --> 01:01:51,920 It's just that. Turn it off! 518 01:01:51,920 --> 01:01:55,920 Anything you don't need, you're not using it. 519 01:01:55,920 --> 01:01:59,920 It's easier than you think to make a difference. 520 01:02:04,920 --> 01:02:11,920 Delegates from around the world are flying into Nairobi for a conference sponsored by the UN to talk about global warming. 521 01:02:13,920 --> 01:02:20,920 Civil servants, professional NGO campaigners, carbon offset fund managers, environmental journalists and others 522 01:02:20,920 --> 01:02:24,920 will discuss every aspect of man-made climate change, 523 01:02:24,920 --> 01:02:30,920 from how to promote solar panels in Africa to the relationship between global warming and sexism. 524 01:02:30,920 --> 01:02:36,920 The conference lasts 10 days, the number of delegates exceeds 6,000. 525 01:02:36,920 --> 01:02:43,920 The billions of dollars invested in climate science means there is a huge constituency of people dependent upon those dollars, 526 01:02:43,920 --> 01:02:47,920 and they will want to see that carry forward. It happens in any bureaucracy. 527 01:02:47,920 --> 01:02:54,920 Where I live, we have a local council global warming officer. 528 01:02:54,920 --> 01:03:07,920 There's a huge tail out there of people who have, in one way or another, been recruited to join this particular bandwagon. 529 01:03:07,920 --> 01:03:14,920 Anybody who then stands up and says, hey, wait a minute, let's look at this coolly and rationally and carefully 530 01:03:14,920 --> 01:03:21,920 and see actually how much merit, how much this stands up, they will be ostracised. 531 01:03:21,920 --> 01:03:29,920 Scientists accustomed to the relative civility and obscurity of academic life suddenly find themselves publicly attacked 532 01:03:29,920 --> 01:03:37,920 if they dare to challenge the theory of man-made global warming, vilified by campaign groups and even within their own universities. 533 01:03:37,920 --> 01:03:42,920 It's the old English saying, if you stand up in the coconut shy, they're going to throw at you. 534 01:03:42,920 --> 01:03:49,920 So I understand that there's going to be some of that, but it gets pretty difficult and pretty nasty and very personal. 535 01:03:49,920 --> 01:03:56,920 And there have been death threats and all sorts of things, so I'm not doing it for my health. 536 01:03:56,920 --> 01:04:05,920 These days, if you are sceptical about the litany around climate change, you're suddenly like as if you're a Holocaust denier. 537 01:04:06,920 --> 01:04:15,920 The environmental movement, really it is a political activist movement, and they have become hugely influential at a global level. 538 01:04:15,920 --> 01:04:19,920 The people got the power. The people got the power. 539 01:04:19,920 --> 01:04:28,920 And every politician is aware of that today. Whether you're on the left, in the middle or the right, you have to pay homage to the environment. 540 01:04:28,920 --> 01:04:32,920 In the past month, the global warming campaign has won a great victory. 541 01:04:32,920 --> 01:04:37,920 The United States government, once a bastion of resistance, has succumbed. 542 01:04:37,920 --> 01:04:40,920 George Bush is now an ally. 543 01:04:40,920 --> 01:04:49,920 Western governments have now embraced the need for international agreements to restrain industrial production in the developed and developing world. 544 01:04:49,920 --> 01:04:54,920 But at what cost? Paul Driesen is a former environmental campaigner. 545 01:04:54,920 --> 01:05:08,920 My big concern with global warming is that the policies being pushed to supposedly prevent global warming are having a disastrous effect on the world's poorest people. 546 01:05:08,920 --> 01:05:12,920 Global warming campaigners say it does no harm to be on the safe side. 547 01:05:12,920 --> 01:05:20,920 Even if the theory of man-made climate change is wrong, we should impose draconian measures to cut carbon emissions just in case. 548 01:05:20,920 --> 01:05:23,920 They call this the precautionary principle. 549 01:05:23,920 --> 01:05:31,920 The precautionary principle is a very interesting beast. It's basically used to promote a particular agenda and ideology. 550 01:05:31,920 --> 01:05:43,920 It's always used in one direction only. It talks about the risks of using a particular technology, fossil fuels, for example, but never about the risks of not using it. 551 01:05:43,920 --> 01:05:47,920 It never talks about the benefits of having that technology. 552 01:05:47,920 --> 01:05:52,920 Anne Muegela is about to cook a meal for her children. 553 01:05:52,920 --> 01:05:58,920 She is one of the two billion people, a third of the world's population, who have no access to electricity. 554 01:05:58,920 --> 01:06:03,920 Instead, they must burn wood or dried animal dung in their homes. 555 01:06:03,920 --> 01:06:08,920 The indoor smoke this creates is the deadliest form of pollution in the world. 556 01:06:09,920 --> 01:06:18,920 According to the World Health Organization, four million children under the age of five die each year from respiratory diseases caused by indoor smoke. 557 01:06:18,920 --> 01:06:23,920 And many millions of women die early from cancer and lung disease for the same reason. 558 01:06:23,920 --> 01:06:33,920 If you were to ask a rural person to define development, they'll tell you, yes, I know I've moved to the next level when I have electricity. 559 01:06:33,920 --> 01:06:40,920 Actually, not having electricity creates such a long chain of problems because the first thing you miss is the light. 560 01:06:40,920 --> 01:06:49,920 So you get that they have to go to sleep earlier because there's no light. There's no reason to stay awake. I mean, you can't talk to each other in darkness. 561 01:06:49,920 --> 01:06:53,920 No refrigeration or modern packaging means that food cannot be kept. 562 01:06:53,920 --> 01:06:58,920 A fire in the hut is too smoky and consumes too much wood to be used as heating. 563 01:06:58,920 --> 01:07:05,920 There is no hot water. We in the West cannot begin to imagine how hard life is without electricity. 564 01:07:05,920 --> 01:07:13,920 The life expectancy of people who live like this is terrifyingly short, their existence impoverished in every way. 565 01:07:16,920 --> 01:07:22,920 A few miles away, the UN is hosting its conference on global warming in its plush gated headquarters. 566 01:07:23,920 --> 01:07:32,920 The gift shop is selling souvenirs of peasant tribal life, while delegates discuss how to promote what are described as sustainable forms of electrical generation. 567 01:07:34,920 --> 01:07:43,920 Africa has coal and Africa has oil, but environmental groups are campaigning against the use of these cheap sources of energy. 568 01:07:44,920 --> 01:07:50,920 Instead, they say Africa and the rest of the developing world should use solar and wind power. 569 01:07:53,920 --> 01:07:58,920 A short drive out of Nairobi, we find our first solar panel. 570 01:07:59,920 --> 01:08:05,920 A Kenyan public health official has brought us to a clinic which serves several villages. 571 01:08:05,920 --> 01:08:14,920 The only electrical implements in the clinic are the electric lights and a refrigerator in which to keep vaccines, medicine and blood samples. 572 01:08:14,920 --> 01:08:18,920 Electricity is provided by two solar panels. 573 01:08:18,920 --> 01:08:21,920 So what can it do successfully? 574 01:08:21,920 --> 01:08:22,920 Lighting. 575 01:08:22,920 --> 01:08:23,920 Lighting only? 576 01:08:23,920 --> 01:08:24,920 Yes. 577 01:08:24,920 --> 01:08:29,920 What happens when you put lighting plus the refrigerator and others? What happens? 578 01:08:29,920 --> 01:08:31,920 It sounds an alarm. 579 01:08:31,920 --> 01:08:33,920 It sounds an alarm? 580 01:08:33,920 --> 01:08:34,920 Yeah. 581 01:08:34,920 --> 01:08:36,920 Can we maybe see that? 582 01:08:36,920 --> 01:08:42,920 The solar panels allow Dr. Samuel Mwangi to use either the lights or the refrigerator, but not both at the same time. 583 01:08:42,920 --> 01:08:45,920 If he does, the electricity shuts down. 584 01:08:46,920 --> 01:08:55,920 Wind and solar power are notoriously unreliable as a source of electricity and are at least three times more expensive than conventional forms of electrical generation. 585 01:08:55,920 --> 01:09:04,920 The question would be how many people in Europe, how many people in the United States are already using that kind of energy and how cheap is it? 586 01:09:04,920 --> 01:09:12,920 You see, if it's expensive for the Europeans, if it's expensive for the Americans, and we are talking about poor Africans, 587 01:09:12,920 --> 01:09:16,920 then we have to think about the cost of electricity. 588 01:09:16,920 --> 01:09:25,920 The rich countries can afford to engage in some luxurious experimentation with other forms of energy, but for us we are still at the stage of survival. 589 01:09:25,920 --> 01:09:33,920 To former environmentalist Paul Driesen, the idea that the world's poorest people should be restricted to using the world's most expensive energy, 590 01:09:33,920 --> 01:09:36,920 is a very important one. 591 01:09:37,920 --> 01:09:48,920 To former environmentalist Paul Driesen, the idea that the world's poorest people should be restricted to using the world's most expensive and inefficient forms of electrical generation, 592 01:09:48,920 --> 01:09:53,920 is the most morally repugnant aspect of the global warming campaign. 593 01:09:54,920 --> 01:09:57,920 Let me make one thing perfectly clear. 594 01:09:57,920 --> 01:10:03,920 If we're telling the third world that they can only have wind and solar power, 595 01:10:03,920 --> 01:10:08,920 what we are really telling them is you cannot have electricity. 596 01:10:09,920 --> 01:10:19,920 The challenge we have when we meet Western environmentalists who say we must engage in use of solar panels and wind energy, 597 01:10:19,920 --> 01:10:23,920 is how we can have Africa industrialized. 598 01:10:24,920 --> 01:10:30,920 Because I don't see how a solar panel is going to power a steel industry. 599 01:10:30,920 --> 01:10:37,920 How a solar panel is going to power maybe some railway train network. 600 01:10:37,920 --> 01:10:41,920 It might work maybe to power a small transistor radio. 601 01:10:44,920 --> 01:10:51,920 I think one of the most pernicious aspects of the modern environmental movement is this romanticization of peasant life. 602 01:10:52,920 --> 01:10:57,920 And the idea that industrial societies are the destroyers of the world. 603 01:10:58,920 --> 01:11:09,920 One clear thing that emerges from the whole environmental debate is the point that there's somebody keen to kill the African dream. 604 01:11:09,920 --> 01:11:11,920 And the African dream is to develop. 605 01:11:12,920 --> 01:11:21,920 The environmental movement has evolved into the strongest force there is for preventing development in the developing countries. 606 01:11:21,920 --> 01:11:27,920 If you're being told don't touch your resource, don't touch your oil, don't touch your coal, that is suicide. 607 01:11:28,920 --> 01:11:30,920 I think it's legitimate for me to call them anti-human. 608 01:11:31,920 --> 01:11:41,920 Like, okay, you don't have to think humans are better than whales or better than owls or whatever if you don't want to. 609 01:11:41,920 --> 01:11:48,920 But surely it is not a good idea to think of humans as sort of being scum. 610 01:11:48,920 --> 01:11:53,920 You know, that it's okay to have hundreds of millions of them go blind or die or whatever. 611 01:11:53,920 --> 01:11:55,920 I just can't relate to that. 612 01:11:56,920 --> 01:12:05,920 The theory of man-made global warming is now so firmly entrenched, the voices of opposition so effectively silenced, it seems invincible. 613 01:12:05,920 --> 01:12:09,920 Untroubled by any contrary evidence, no matter how strong. 614 01:12:10,920 --> 01:12:14,920 The global warming alarm is now beyond reason. 615 01:12:15,920 --> 01:12:19,920 There will still be people who believe that this is the end of the world. 616 01:12:19,920 --> 01:12:32,920 Particularly when you have, for example, the chief scientist of the UK telling people that by the end of the century the only habitable place on the earth will be the Antarctic. 617 01:12:33,920 --> 01:12:40,920 And humanity may survive thanks to some breeding couples who moved to the Antarctic. 618 01:12:40,920 --> 01:12:42,920 I mean, this is hilarious. 619 01:12:42,920 --> 01:12:47,920 It would be hilarious, actually, if it weren't so sad.
