No Cause for Alarm Over Sea Level or Ice Sheets
Professor Cliff Ollier
John Le Mesurier’s recent article in On Line Opinion, ”The Creeping Menace” , re-hashes the alarmism about rising sea levels. Much has happened, however, since Al Gore scared the world with visions of metre high seas flooding New York.
First, there is still no proof the Earth is experiencing “dangerous” warming. Temperatures have levelled off since 1998. Many measuring locations are also located in unsuitable areas. Furthermore, the methodologies of averaging temperature are inconsistent and full of problems. This is why “Global Warming” was replaced as a slogan by “Climate Change” (nobody denies that climate changes), and more recently by “Climate Disruption” (which is impossible define or prove).
Second, the increased temperature is supposed to increase sea level mainly by melting the ice-caps, which is impossible. Thermal expansion of the oceans seems to be of little consequence at present because the satellite measurements show the oceans are cooling. Le Mesurier gilds his picture with a few asides on “extreme climatic events” in general and hurricanes in particular. Recent studies, however, show no increase in hurricane activity in the last 40 years.
With regard to sea level, I have come to the view the IPCC and Australian Bureau of Meteorology, run by CSIRO, are unreliable sources of data after critically assessing their statements on this subject for some time. Direct studies of sea level are showing only small rises. You can see the sea level data for yourself for the United States and a few other countries here. Most stations show a rise of sea level of about 2mm per year, but note the considerable variation even within a single state.
Models depend on what is put into them. For example, a 2009 report by the CSIRO for the Victorian Government’s Future Coasts Program on The Effect of Climate Change on Extreme Sea Levels in Port Phillip Bay based its model on temperature projections to 2100 of up to 6.4 degrees. That is the most extreme, fuel intensive, scenario of the IPCC and implies unbelievable CO2 concentration levels in 2100 of approximately 1550 parts per million (expressed in CO2 equivalent). Usage of all known fossil fuel reserves would only achieve half of this and continuation of the current rate of increase in concentration levels would result in only 550ppm by 2100.
In terms of sea levels, the result is a CSIRO predicted rise for Port Phillip Bay by 2100 of 82cm and, with the help of the Bureau of Meteorology, an increase due to wind to 98cm. That is not only well above even the top level projected by the latest IPCC report but is also well above any projections from the last 20 to 100 years.
Two favourites of sea level alarmists are Tuvalu and the Maldives. Sea level measurements for Tuvalu (and 10 other stations) between 1992 and 2006 are available on Fig. 13 on the Australian Bureau of Meteorology website (PDF 1.97MB). For about the past eight years the sea level seems to be virtually constant. Vincent Gray has reviewed the evidence and finds virtually stable sea levels in the South West Pacific, and he also discusses how the data have been manipulated to suggest rising sea level.
Sea level in the Maldives was studied in enormous detail by the doyen of sea level scientists, Niklas Axel-Mörner. His team determined the sea level curve over the past 5,000 years based on evidence of morphology, stratigraphy, biology and archaeology supported by extensive C14 dating, and found that “All over the Maldives there is evidence of a sub-recent sea level some 20cm higher than the present one. In the 1970s, sea level fell to its present position.”
Incidentally a recent study of coral islands in the Pacific by Webb and Kench showed the islands are actually growing larger despite any possible sea level rise.
Holland is very low and would be particularly vulnerable to any large rise of sea level. It is also a world leader in coastal study and engineering, and the Dutch are not alarmed. In the December 11, 2008, issue of NRC/Handelsblad (Rotterdam’s counterpart to The Australian or The Age) Wilco Hazeleger, a senior scientist in the global climate research group at the Royal Netherlands Meteorological Institute wrote:
In the past century the sea level has risen twenty centimetres. There is no evidence for accelerated sea-level rise. It is my opinion that there is no need for drastic measures. Fortunately, the time rate of climate change is slow compared to the life span of the defense structures along our coast. There is enough time for adaptation.
What about the alleged cause of most of the scary sea level rise - the melting of ice-caps? This idea of rapid loss of ice is based on the concept of an ice sheet sliding down an inclined plane on a base lubricated by meltwater, which is itself increasing because of global warming.
In reality the Greenland and Antarctic ice sheets occupy kilometre-deep basins. If sliding were operative they could only slide into the basin. Virtually all the studies on which alarmist conclusions are based are on the outflowing glaciers around the edges of Greenland where glaciers can flow downhill, and where there is some melting. There is no melting in the interior of ice sheets - it is far too cold.
Glaciers have a budget, with accumulation of snow, conversion to ice, flow of ice, and eventual destruction by melting, ablation or collapse. The centres of the ice sheets, occupying basins, flow only at the base, warmed by geothermal heat and driven by the weight of the overlying ice. There is no direct flow of the near-surface ice in the centre of an ice sheet to the outflow glaciers.
The accumulation of kilometres of undisturbed ice in cores in Greenland and Antarctica show hundreds of thousands of years of accumulation with no gaps in the record caused by melting. The existence of such layers, youngest at the top and oldest at the bottom, enables the glacial ice to be studied through time, a basic source of data on temperature and carbon dioxide in the past.
In the Greenland ice sheet several cores have more than 3km of undisturbed ice which go back in time for over 105,000 years (much less than the Antarctic equivalent). The Vostok cores in Antarctica provide data for the past 414,000 years before the ice starts to be deformed by flow (induced by the weight of the overlying ice and geothermal heat). The Epica core in Antarctica goes back to 760,000 years. The cores show there have been many times when the climate was much warmer than today (e.g. Mediaeval Warm Period). It is fanciful to conclude kilometres of ice can suddenly melt when the records show no melting whatsoever in the ice sheet accumulation areas. After considering the evidence of three quarters of a million years of documented continuous accumulation, how can we rationally accept that right now the world’s ice sheets are collapsing?
The idea of a glacier sliding downhill on a base lubricated by meltwater seemed a good idea when first presented by de Saussure in 1779, but a lot has been learned since then. Not even alpine valley glaciers or the outflow glaciers of Greenland move this way, but by a process called creep, best known from metallurgy. This process explains why the crystals of ice in the snout of a glacier are about a thousand times bigger than the first crystals in the snowfall. Sliding cannot account for this.
Collapse of ice sheets is commonly shown to stir fears of rising sea levels. Yet wherever ice sheets or glaciers reach the sea, the ice floats and eventually breaks off to form icebergs. It is part of the glacial budget: the glaciers never did flow on to the equator. Icebergs have always been with us. Captain Cook saw them on his search for the Great South Land.
Observers frequently seem surprised by the size and suddenness of what they see. In 2007, when a piece of the Greenland ice shelf broke away, the scientists who were interviewed said they were surprised at how suddenly it happened. How else but suddenly would a piece of ice shelf break off? The actual break is inevitably a sudden event - but one that can easily be built into a global warming horror scenario. The point to remember is that the release of icebergs at the edge of an ice cap does not in any way reflect present-day temperature. It takes thousands of years for the ice to move from accumulation area to ice front.
The Hubbard Glacier in Alaska has long been a favourite place for tourists to witness the collapse of an ice front, 10km long and 27m high, sometimes producing icebergs the size of ten-storey buildings. One tourist wrote “Hubbard Glacier is very active and we didn’t have long to wait for it to calve”. Yet the Hubbard Glacier is advancing at 25 metres per year, and has been doing so at least since its discovery in 1895.
Variations in melting or calving around the edges of ice sheets are no indication that they are collapsing, but reflect past rates of snow and ice accumulation in their interior.
Despite alarmist propaganda there is much evidence to suggest that the ice sheets are in good health.
For example, one recent paper is entitled “A doubling in snow accumulation in the western Antarctic Peninsula since 1850” (Thomas et al. 2008).
Another reports that “The East Antarctic ice-sheet north of 81.60S increased in mass by 45 plus/minus 7 billion metric tons per year from 1992 to 2003… enough to slow sea-level rise by 0.12 plus/minus 0.002 millimetres per year” (Davis et al. 2005).
Wingham et al. (2006) wrote: “We show that 72 per cent of the Antarctic ice sheet is gaining 27 ± 29 Gt yr-1, a sink of ocean mass sufficient to lower global sea levels by 0.08 mm yr-1.”
Johannessen and colleagues analysed satellite data on the Greenland Ice Sheet from 1992 to 2003. They found an increase of 6.4 plus/minus 0.2 centimetres per year in the vast interior areas above 1500 metres, in contrast to previous reports of high-elevation balance. Below 1500 metres, the elevation-change rate is -2.0 plus/minus 0.9 cm/year.
Of course even if we believe global sea level is rising, it takes another leap of faith to accept that it is caused by minuscule increases in atmospheric carbon dioxide caused by human activity.

So is the world predictable or not? The environmentalists’ contradiction
Dan Gardner
It’s a soggy Monday night but the pews in one of Ottawa’s most spacious churches are overflowing with believers. “We have tried to assume the position of the gods,” the angry man at the lectern thunders, “without the knowledge to manage our ecological footprint.”
No, the speaker is not a preacher, at least not a preacher of the conventional sort. He is David Suzuki, scientist, environmentalist, icon.
The natural systems that sustain us are infinitely complex, he tells the worshipful audience. We are only beginning to understand them and we cannot possibly predict what effect the actions and technologies of almost seven billion people will have on them. We must be humble. We must be cautious and reverent. “We don’t know enough to take the place of the gods,” he proclaims.
It’s a familiar theme, which is appropriate because Suzuki, at 74, is summing up his life’s work—his “legacy,” as he puts it in the title of his new book.
Suzuki delivers another familiar theme this night. He illustrates it with a thought experiment.
Imagine a test tube filled with food. That’s the Earth, he says. Now introduce a single bacterium to that test tube and let it grow exponentially. In the first minute, one bacterium becomes two bacteria. In the second minute, two become four. Four become eight. Eight become 16. If it takes one hour for the bacteria to multiply until they fill the entire test tube and there’s no more food—and the bacteria all die—when will the test tube be exactly half full of food and half full of bacteria?
In the 59th minute. Which is strange because at that moment things look fine. But the very next minute, catastrophe strikes.
“Every scientist I talk to agrees with me,” Suzuki declares, “that we’re already past the 59th minute.” We must drastically change the way we live, immediately, or we are doomed.
Neither of these themes is unique to Suzuki. Indeed, they are standard fare among environmentalists. And therein lies a little-recognized paradox.
I recently wrote a book called Future Babble (to be released Oct. 12), which is about expert predictions, why they fail, and why we believe them anyway. The experience of sifting through heaps and heaps of failed predictions has made me quite sympathetic to Suzuki’s first theme of humility. We truly are awful at foreseeing what is to come. And there’s little reason to think we’ll get much better. Indeed, key properties of complex systems make prediction inherently impractical or even impossible. We really should be humble. And cautious.
But how can a humble and cautious man say we are “past the 59th minute”? To know that, one must fully understand all those complex natural systems—to say nothing of social systems—and be able to see how they will develop in the future. Monday night, Suzuki said this is now possible thanks to “scientists and supercomputers”—the same scientists with supercomputers who “don’t know enough to take the place of the gods.”
This stunning contradiction shows up most clearly when environmentalists talk about climate change. On the one hand, greens oppose geo-engineering schemes—deliberate attempts to alter the atmosphere to counteract the effects of climate change—on the grounds that we cannot possibly predict the consequences of our actions. But they also treat forecasts of what will happen if humanity doesn’t curtail carbon dioxide emissions as perfectly reliable glimpses of the future. That makes no sense. Either we can reliably predict the effect human actions have on climate and the natural world or we cannot. Which is it?
Environmental activism is steeped in this contradiction. A 1992 statement by leading scientists warned of “unpredictable collapses of critical biological systems” and insisted—rightly, I believe --that this uncertainty strengthens the case for action. But then the statement declared humanity had “no more than one or a few decades” to make the necessary changes. If the collapses are unpredictable, how could they possibly know how much time we have to avert them?
This isn’t humility. It’s hubris. To see how foolish it is, consider the history of similar forecasts.
The famous and revered 1972 report “Limits to Growth”—the first to dazzle the world with “scientists and supercomputers”—opened with a statement from UN secretary general U Thant that the world has “perhaps 10 years left” to stave off calamity. The report itself offered computer-generated forecasts that supported this claim: Radical changes implemented in the 1970s would avert disaster, the forecasts showed, but it would be too late if the same changes were not implemented until the year 2000. Either that report was wrong then, or Suzuki is wrong now. There’s no way around it.
But Suzuki seems not to care for historical references like this. He even lionizes the ecologist Paul Ehrlich, the author of 1968 smash The Population Bomb, who made a long list of predictions that failed, using essentially the same analysis as Suzuki. In 1974, for example, Ehrlich argued that growing resource shortages would make Americans and others drastically poorer in the years ahead, putting an end to consumerism and the conventional economics of growth. “We are facing, within the next three decades, the disintegration of nation-states infected with growthmania,” Ehrlich wrote. Thus, it was a little odd to listen on Monday as David Suzuki railed against the consumerism and economic growth which Ehrlich said would be swept away long ago.
And then there were the two books which introduced a young Paul Ehrlich to ecology. Both William Vogt’s Road to Survival and Fairfield Osborn’s Our Plundered Planet were published in 1948. Both were influential best-sellers. Both made arguments similar to Ehrlich’s and Suzuki’s. And both were stuffed with predictions that flopped: “The most critical danger is that we shall not realize how short we are of that one unrenewable resource—time,” wrote Vogt. “If we wait until next year, or the next decade, to push our search for a solution, then our fate may well be sealed.”
We never learn. Earlier this year, scientists delivered the startling news that despite increases in sea level caused by climate change, only four out of 27 small Pacific islands surveyed were smaller than they had been in the 1950s. The remaining 23 had either stayed the same size or grown, thanks to offsetting accumulations of coral debris.
Water rises; islands get smaller. It seems like the simplest thing in the world to predict.
Nature constantly surprises us, Suzuki said Monday night. “I hope we can learn some humility.” Indeed.

Climate ‘Fraudster’ Michael Mann Speaks Out - Science News; AGU denies climate response team
Tom Nelson
Reality denier: After polar bear numbers have greatly increased since the cooling scare of the 1970s, he now suggests that CO2 may kill them all by the time his daughter grows up
Climate [Fraudster Michael Mann] Speaks Out - Science News
Late the morning of November 7, Mann stepped in front of a crowd of reporters just off the campus of Yale University, as part of a plenary panel at the annual Council for the Advancement of Science Writing meeting. It was a friendly crowd, most of whom had spent years covering the overwhelming scientific evidence that greenhouse gases put into the atmosphere by human activities are causing global temperatures to heat up.
...
Mann concluded that “there’s not just a hockey stick - there’s a hockey league.” Some scientific uncertainties do remain about climate change, such as the precise effects of clouds in a changing climate. “There are legitimate uncertainties,” Mann said, “but unfortunately the public discourse right now is so far from scientific discourse.”
...
I’ve seen Mann in this frame of mind before; several years ago he testified in front of some of his staunchest critics at a National Academy of Sciences panel set up to review the hockey stick work. The jaw I saw clenched back then seemed not to have loosened, even when the audience was a group of friendly journalists rather than aggressive panel questioners. (The final NAS report reaffirmed the basic science underlying the hockey stick reconstruction.)
Yet Mann remains keenly aware of the political import of every word. He ended his talk with an impassioned plea to action, complete with a picture of his daughter marveling at swimming polar bears at the local zoo. “I can’t imagine having to tell her when she’s grown up that the polar bears became extinct,” he said, “because we didn’t act soon enough to combat a problem that we knew was real but that we couldn’t convince the public of.”
See post here. See Steve McIntyre on Mann’s where he comments “...one sees someone who purports to be a “scientist” making unsupportable statements” here.

Inaccurate news reports misrepresent a climate-science initiative of the American Geophysical Union
WASHINGTON-An article appearing in the Los Angeles Times, and then picked up by media outlets far and wide, misrepresents the American Geophysical Union (AGU) and a climate science project the AGU is about to relaunch. The project, called Climate Q&A Service, aims simply to provide accurate scientific answers to questions from journalists about climate science.
“In contrast to what has been reported in the LA Times and elsewhere, there is no campaign by AGU against climate skeptics or congressional conservatives,” says Christine McEntee, Executive Director and CEO of the American Geophysical Union. “AGU will continue to provide accurate scientific information on Earth and space topics to inform the general public and to support sound public policy development.”
AGU is the world’s largest, not-for-profit, professional society of Earth and space scientists, with more than 58,000 members in over 135 countries.
“AGU is a scientific society, not an advocacy organization,” says climate scientist and AGU President Michael J. McPhaden. “The organization is committed to promoting scientific discovery and to disseminating to the scientific community, policy makers, the media, and the public, peer-reviewed scientific findings across a broad range of Earth and space sciences.”
AGU initiated a climate science Q&A service for the first time in 2009 to provide accurate scientific information for journalists covering the United Nations Climate Change Conference in Copenhagen. AGU has been working over the past year on how to provide this service once again in association with the upcoming UN Climate Change Conference in Cancun, Mexico.
AGU’s Climate Q&A service addresses scientific questions only. It does not involve any commentary on policy. Journalists are able to submit questions via email, and AGU member-volunteers with Ph.D.s in climate science-related fields provide answers via email.
The relaunch of the Climate Q&A service is pending. When AGU is ready to announce the service, we will notify journalists on our distribution list via a media advisory that the service is once again available for their use.
For additional information about the Q&A service please see a 2 March 2010 article about the 2009 Q&A service that was published in AGU’s weekly newspaper Eos, and a blog post about the service on AGU’s science communication blog The Plainspoken Scientist.
The American Geophysical Union was established in 1919, and is headquartered in Washington, D.C. AGU advances the Earth and space sciences through its scholarly publications, meetings and conferences, and outreach programs. For more information, please visit the AGU web site.

Climate Scientists Plan Campaign Against Global Warming Skeptics
By Dr. Roy Spencer
"The American Geophysical Union plans to announce that 700 researchers have agreed to speak out on the issue. Other scientists plan a pushback against congressional conservatives who have vowed to kill regulations on greenhouse gas emissions.”
A new article in the LA Times says that the American Geophysical Union (AGU) is enlisting the help of 700 scientists to fight back against a new congress that is viewed as a bunch of backwoods global warming deniers who are standing in the way of greenhouse gas regulations and laws required to same humanity from itself.
Scientific truth, after all, must prevail. And these scientists apparently believe they have been endowed with the truth of what has caused recent warming.
The message just hasn’t gotten across.
We skeptics are not smart enough to understand the science. We and the citizens of America, and the representatives we have just elected to go to Washington, just need to listen to them and let them tell us how we should be allowed to live.
OK, so, let me see if I understand this.
After 20 years, billions of dollars in scientific research and advertising campaigns, cooperation from the public schools, TV specials and concerts by a gaggle of entertainers, end-of-the-world movies, our ‘best’ politicians, heads of state, presidents, the United Nations, and complicity by most of the news media, it has been decided that the American public is not getting the message on global warming!?
Are they serious!?
Americans - hell, most of humanity - have already heard the 20 different ways we will all die miserable deaths from our emissions of that life giving - er, I mean poisonous - gas, carbon dioxide, that we are adding to the atmosphere every day.
So, NOW it no more mister nice guy? Give me a break.
Finally Time for a REAL Debate?
Actually, this announcement is a good thing. There has been a persistent refusal on the part of the elitist, group-think, left-leaning class of climate scientists to even debate the global warming issue in public. Maybe they have considered it beneath themselves to debate those of us who are clearly wrong on the global warming issue.
A complaint many of us skeptics have had for years is that those who constitute the “scientific consensus” (whatever that means) will not engage in public debates on global warming. Al Gore won’t even answer questions from the press.
This is why you will mostly hear only politicians and U.N. bureaucrats give pronouncements on the science. They are already adept at weaving a good story with carefully selected facts and figures.
Why has the global warming message been presented mostly by politicians and bureaucrats up until now? Probably because it is too dangerous to put their scientists out there.
Scientists might admit to something counterproductive - like uncertainty - which would jeopardize what the politicians have been trying to accomplish for decades - control over energy, which is necessary for everything that humans do.
Scientists Ready to Enter the Lion’s Den
The LA Times articles goes on to explain how there will be “scientists prepared to go before what they consider potentially hostile audiences on conservative talk radio and television shows.”
Gee, how brave of them.
Kind of like when I went up against Henry Waxman? Or Barbara Boxer?
I can sympathize with Republican’s desire to have hearings to investigate how your tax dollars have been spent on this issue. But I will guarantee that if such hearings are held, the news media will make it sound like Galileo is being tried all over again.
As if climate scientists are objective seekers of the truth. I hate to break it to you, but scientists are human. Well...most of us are, anyway.
Most have strong personal, quasi-religious views of the role of humans in the natural world, and this inevitably guides how they interpret measurements of the climate system. Especially the young ones who have been indoctrinated on the subject.
Those few of us who are publishing climate researchers and who are willing to take the risk of speaking out on the biased science on this issue are now late in our careers, and we have seen the climate research field be transformed from one where “climate change” used to necessarily imply natural climate change, to one where nature does not have the power to cause its own change - only mankind does.
I have repeatedly pointed out how virtually all global warming research funds either (1) build the case for humanity as the primary cause of recent warming, or (2) simply assume humans are the cause.
Virtually NO funding has supported research into the possibility that warming might be mostly part of a natural climate cycle. And if you give scientists enough money to find something, they will do their best to find it.
Politicians have orchestrated and guided this effort from the outset, and scientists like to believe they are helping to Save the Earth when they participate in global warming research.
Anthropogenic Global Warming is a Hypothesis, Nothing More
What the big-government funded climate science community has come up with is a plausible hypothesis which is being passed off as a proven explanation.
Science advances primarily by searching for new and better explanations (hypotheses) for how nature works. Unfortunately, this basic task of science has been abandoned when it comes to explaining climate change.
About the only alternative explanation they have mostly ruled out is an increase in the total output of the sun.
The possibility that small changes in ocean circulation have caused clouds to let in more sunlight is just one of many alternative explanations which are being ignored.
Not only have natural, internal climate cycles been ignored as a potential explanation, some researchers have done their best to revise climate history to do away with events such as the Medieval Warm Period and Little Ice Age. This is how the ‘hockey stick’ controversy got started.
If you can get rid of all evidence for natural climate change in Earth’s history, you can make it look like no climate changes happened until humans (and cows) came on the scene.
Bring It On
I look forward to the opportunity to debate a scientist from the other side who actually knows what they are talking about. I’ve gone one-on-one with some speakers who so mangled the consensus explanation of global warming that I had to use up half my speaking time cleaning up the mess they made.
Those few I have debated in a public forum who know what they are talking about are actually much more reserved in their judgment on the subject than those who the pop culture presents to us.
But for those newbie’s who want to enter the fray, I have a couple of pieces of advice on preparation.
First, we skeptics already know your arguments...it would do you well to study up a little on ours.
And second, those of us who have been at this a long time actually knew Galileo. Galileo was a good friend of ours. And you are no Galileo.

Consensus: Climate Votes Caused Bloody Mess
By Paul Chesser
Is there any aspect of the Democrats’ actions that didn’t take them down on Tuesday? Obamacare took down the Democrats, spending took down the Democrats, the economy took down the Democrats...and now Politico adds the climate agenda:
Democrats who voted for the controversial House climate bill were slaughtered at the ballot box, including Rep. Rick Boucher, the 14-term Virginian who helped broker some of the key deals instrumental to its June 2009 passage. In the Senate, several reliable green advocates also went down to opponents who derided tough new environmental policies.
Come January, Obama will be working with a Congress that will have little appetite for the types of sweeping energy reform he sought over the last two years. With the House in Republican hands, some of the climate issue’s most vocal advocates have been dislodged from their powerful perches, including Speaker Nancy Pelosi and Energy and Commerce Committee Chairman Henry Waxman.
There’s no hiding the House Democrats’ bloodbath, with more than two dozen members who voted for the Pelosi-led climate bill losing their seats, and more likely to fall as the final tallies come in. The outcome sends a strong signal to moderate lawmakers as they consider any risky votes in future Congress’ on energy and environmental issues.
Turns out the scientific consensus on global warming produced a forensic consensus that it caused a political mass murder of Democrats. Read more here.

What the Green Movement Got Wrong
A group of environmentalists across the world believe that, in order to save the planet, humanity must embrace the very science and technology they once so stridently opposed.
In this film, these life-long diehard greens advocate radical solutions to climate change, which include GM crops and nuclear energy. They argue that by clinging to an ideology formed more than 40 years ago, the traditional green lobby has failed in its aims and is ultimately harming its own environmental cause.
As author and environmentalist Mark Lynas says, ‘Being an environmentalist was part of my identity and most of my friends were environmentalists. We were involved in the whole movement together. It took me years to actually begin to question those core, cherished beliefs. It was so challenging it was almost like going over to the dark side. It was a like a horrible dark secret you couldn’t share with anyone.’
Directly following this programme, there will be a live studio debate chaired by Krishnan Guru-Murthy to discuss the issues raised.
Krishnan Guru-Murthy chairs a studio debate to discuss the issues raised in the documentary, What the Green Movement Got Wrong.
The film’s leading protagonists, former anti-GM activist and author Mark Lynas and Stewart Brand, a pioneer of the original green lobby, face critics from today’s green movement in front of an informed studio audience.
Leading policy makers, commentators, scientists, entrepreneurs and economists debate the impact the green movement has had on global climate change and whether embracing the very science and technology the greens once so stridently opposed, such as GM crops and nuclear energy, would be more successful in reducing the risks to the planet from global warming.
