Climate change will 'make Britain cooler'
For the first time, the UN Intergovernmental Panel on Climate Change (IPCC) is due to give a clear prediction of how global warming will affect currents in the Atlantic Ocean.
It will say that the circulation of warm and cold water in the Atlantic, which includes the Gulf Stream, will weaken by 20 to 44 per cent by the end of the century.
Scientists claim that such a slow-down in the Gulf Stream will have a big impact on Britain, causing cooling of about 1.8F (1C) and disrupting weather patterns.
The Gulf Stream carries warm water from the equator to the west coast of Britain, making the country’s climate warmer than it otherwise would be.
Scientists warn that the resulting cooling would mask the impacts of global warming on the country, but play havoc with the weather.
The panel is due to publish the predictions in its fifth major assessment of global warming on Friday. Compiled by more than 2,000 scientists over three years, it is intended to be the most comprehensive analysis of climate change and its underlying causes.
The report will say that the warming of the oceans will interfere with the currents in the Atlantic, also known as the Atlantic Meridional Overturning Circulation (AMOC). It will state: “It is very likely that the Atlantic Meridional Overturning Circulation will weaken over the 21st century. It is likely that there will be some decline in the AMOC by 2050, but there will be some decades when the AMOC increases.”
The report provides a basis for governments to draw up policies aimed at tackling climate change and reducing carbon dioxide emissions.
But tense discussions this week between officials from several governments over the final wording of the report have fallen a long way behind schedule.
Prof Corinne Le Quéré, the director of the Tyndall Centre for Climate Change Research at the University of East Anglia and one of the report’s authors, said: “The policymakers see the information from quite a different angle as they have to make a relationship with policy.
“They go through it line by line, paragraph by paragraph and suggest changes which the scientists then respond to.”
Delegates stayed up until 3am on Thursday morning as they deliberated over controversial points, such as the current “pause” in the global temperature rise.
Negotiations were expected to drag into the early hours of this morning as officials attempt to finalise the report.
Delegates have agreed the wording of the report’s summary on topics such as historic temperatures, sea level rise and the melting of glaciers. Debate on some sections including “attribution”, the extent to which humans are responsible for global warming, started on Thursday.
At one stage, officials from Britain, the USA, Brazil and other leading powers stepped in to alter the wording of a section addressing the comparatively slow rise in global temperatures over the past 15 years; the so-called warming “pause”.
They demanded that the wording be changed to explain the slowdown and wanted to insert clauses emphasising that global warming has not stopped.
A source at the meeting said the officials had “spent hours trying to make the language as clear as possible”.
Sceptics have pointed at the pause in global temperature increase as a sign that predictions of catastrophic global warming do not reflect the reality.
They have argued that the way the climate responds to increasing carbon dioxide levels in the atmosphere is not fully understood, so major decisions by governments should be delayed.
Dr Benny Peiser, the director of the Global Warming Policy Foundation, warned that no previous climate change models had “predicted the warming pause”. He said the “IPCC is a highly political process and it often fails to reflect that the models do not accurately reflect what is going on”.
Lord Stern, who conducted a review into the economics of climate change for the Labour government, said the “kind of temperatures we risk” would “probably involve a recasting of where many people could live”. He said those opposing action on climate change would have to “argue that they are confident that the risks are small, which would be an astonishing statement to make”.
Warming Plateau? Climatologists Face Inconvenient Truth
From Germany's "Spiegel"
Data shows global temperatures aren't rising the way climate scientists have predicted. Now the Intergovernmental Panel on Climate Change faces a problem: publicize these findings and encourage skeptics -- or hush up the figures.
For a quarter of a century now, environmental activists have been issuing predictions in the vein of the Catholic Church, warning people of the coming greenhouse effect armageddon. Environmentalists bleakly predict global warming will usher in plagues of biblical dimensions -- perpetual droughts, deluge-like floods and hurricanes of unprecedented force.
The number of people who believe in such a coming apocalypse, however, has considerably decreased. A survey conducted on behalf of SPIEGEL found a dramatic shift in public opinion -- Germans are losing their fear of climate change. While in 2006 a sizeable majority of 62 percent expressed a fear of global warning, that number has now become a minority of just 39 percent.
One cause of this shift, presumably, is the fact that global warming seems to be taking a break. The average global temperature hasn't risen in 15 years, a deviation from climatologists' computer-simulated predictions.
This is a difficult state of affairs for the Intergovernmental Panel on Climate Change (IPCC), which will release its next assessment report on global warming on Friday, Sept. 27.
None of the authors involved in the report are allowed to comment publicly on the report's contents before its official release. Only after days of closed-door negotiations -- which begin in Stockholm this Monday, Sept. 23 -- will the international forecasting body release its findings.
This much, though, is certain -- the new predictions will be essentially the same as the old ones, albeit a little more precise. The only adjustment the IPCC is expected to make is an increase in the predicted rise of sea levels. The new report is expected to forecast that coastal waters may rise by between 29 and 82 centimeters (11 and 32 inches) by the end of the century.
The crucial question, however, is: How will the IPCC address the pause in global warming? And how reliable are the computer models on which the predictions are based, if they failed to foresee the current temperature plateau?
In the lead-up to this week's conference, tensions have been high between the IPCC's climate researchers and the IPCC's government representatives, with Germany's governmental delegates playing a particularly questionable role.
The conference's participants will negotiate the creation of a 30-page summary for policymakers from the 1,000-page full report. Governments send representatives from their relevant ministries in order to have a hand in what message that summary will contain. In Germany's case, this means delegates from the Federal Ministries for the Environment and Research.
"If you are offering the choice between 'alarmist' and 'sceptic' then the German delegation is certainly more in the direction of 'alarmist'. But this is too simple a distinction," says British climatologist Mike Hulme from King's College London, who has many years of experience with IPCC bureaucracy.
German Green Party politician Hermann Ott, on the other hand, is satisfied with Germany's conduct in the negotiations. Since Helmut Kohl's government, Ott says, there has generally been consensus on the significance of climate protection, making it possible for "a great deal of continuity and a high level of expertise" to develop within Germany's Federal Ministry for the Environment.
Despite resistance from many researchers, the German ministries insist that it is important not to detract from the effectiveness of climate change warnings by discussing the past 15 years' lack of global warming. Doing so, they say, would result in a loss of the support necessary for pursuing rigorous climate policies. "Climate policy needs the element of fear," Ott openly admits. "Otherwise, no politician would take on this topic."
Science vs. Climate Politics
Germany's Federal Ministry of Research would prefer to leave any discussion of the global warming hiatus entirely out of the new IPCC report summary. "In climate research, changes don't count until they've been observed on a timescale of 30 years," claims one delegate participating in the negotiations on behalf of German Research Minister Johanna Wanka of the Christian Democratic Union (CDU). The Ministry for the Environment's identical stance: "Climate fluctuations that don't last very long are not scientifically relevant."
At most, German delegates at the conference would be willing to include an admission that "the pace of temperature change has slowed" -- a reinterpretation that doesn't correspond to the latest research findings.
Germany's highest-ranking climate researcher, physicist Jochem Marotzke, director of the Max Planck Institute for Meteorology, in Hamburg, is fighting back against this refusal to face facts. Marotzke, who is also president of the German Climate Consortium and Germany's top scientific representative in Stockholm, promises, "We will address this subject head-on." The IPCC, he says, must engage in discussion about the standstill in temperature rise.
Marotzke calls the claim that a temperature plateau isn't significant until it has lasted for over 30 years unscientific. "Thirty years is an arbitrarily selected number," he says. "Some climate phenomena occur on a shorter timescale, some on a longer one." Climate researchers, Marotzke adds, have an obligation not to environmental policy but to the truth. "That obligates us to clearly state the uncertainties in our predictions as well," he says.
The researchers' problem: Their climate models should have been able to predict the sudden flattening in the temperature curve. Offering explanations after the fact for why temperatures haven't increased in so long only serves to raise doubts as to how reliable the forecasts really are.
Despite this, most Germans have not yet lost their faith in climate research. According to the SPIEGEL survey, 67 percent of Germans still consider the predictions reliable.
Possible Explanations for the Pause
In any case, scientists have discovered some possible indications as to why temperatures are not currently rising. One explanation involves the Pacific Ocean, which, calculations indicate, has absorbed an unusually large amount of heat from the Earth's atmosphere in recent years. "If this proves to be true, then the warnings are still in effect," Marotzke says. He explains that it would mean the greenhouse effect is adding more and more energy into the climate system, exactly as the simulations predict, just with a larger portion of that energy than expected disappearing temporarily into the ocean.
Another possible explanation is that the large quantity of soot emitted into the atmosphere by cars and factory smokestacks in Asia has had a cooling effect on the atmosphere. What will happen when China installs modern filtering systems on a massive scale in its vehicles and at its coal power plants? In this case, global warming would also then continue unchecked.
In other words, says glaciologist Heinz Miller at the Alfred Wegener Institute for Polar and Marine Research, "The stagnation in temperature does not negate the physical evidence of global warming." Still, he says, the IPCC needs to make clear to the public and politicians alike that "scientific study is not a guarantee for infallibility." Miller also believes, "There is still a considerable need for more research."
Environmental policymakers within the IPCC fear, though, that climate skeptics and industry lobbyists could exploit these scientific uncertainties for their own purposes. The IPCC's response has been to circle the wagons. To ensure it remains the sole authority on climate predictions, the panel plans not to publish the complete report for some time after the release of the summary and not even release transcripts from the negotiations in Stockholm.
This despite the IPCC's promise for more transparency after hair-raising mistakes in the last assessment report -- from 2007 -- emerged three years ago and tarnished the panel's credibility. One result of that scandal was a commitment to avoiding future conflicts of interest. Yet scientists who previously worked for environmental organizations still hold leading roles in the creation of the IPCC report. This includes at least two "coordinating lead authors" who are responsible for individual chapters of the report.
This week, the United Nations‘ Intergovernmental Panel on Climate Change is slated to release its fourth report since 1990. Leaked copies indicate an admission that there has been no global warming for the past 16 years, but the report will also increase its probability from 90 percent to 95 percent that global warming — if it does occur — is caused by man. Not one of the major climate models on which the panel bases its predictions forecast the lack of warming over the past 16 years, even though the models do vary widely as to how much warming they predicted.
Not to be outdone, President Obama again is warning us that if the Republicans do not vote for more government spending in the budget battles that are now upon us, we will go back into a recession. You may have not noticed we had left the recession, since employment levels are still below where they were five years ago. The president, of course, does not make such statements off the top of his head, but on the basis of his economic-forecast models. You might ask: “How accurate have these models been in forecasting?” Please note the accompanying table for the answer.
The Obama administration’s Office of Management and Budget makes five-year economic forecasts each year, but to spare it some pain, I took only its two-year forecasts. As you can see, the administration’s average error was well over 100 percent — making its projections almost useless. However, many private-sector economic forecasters managed to get much closer to the mark. The relevant question is this: “Why are both the climate-forecast models and some of the government economic-forecast models prone to not only gross error, but also consistent overestimates?”
Many years ago, when I was chief economist for the U.S. Chamber of Commerce, one of my jobs was to produce a quarterly forecast of the U.S. economy, so I do have some sympathy for those whose job it is to produce forecasts. When constructing a forecast model, it is necessary to identify the key variables that will likely determine the future and then to specify those variables correctly. Good forecasters are constantly modifying their models to correct for past mistakes and take in new data. A consistent overestimate or underestimate often indicates a mistaken specification of some key variable.
The major long-range climate-change models appear to have over-weighted the effect of increased carbon dioxide, and under-weighted some other key variables, which caused almost all of them to forecast far more warming than actually occurred. It is hard enough to build a reasonably accurate economic-forecast model, let alone a climate-change model, which is far more complex with even less reliable data. Too many climate-change scientists appear have been affected with an unwarranted hubris about what they knew. Many in the political and media classes accepted their doomsday predictions with insufficient skepticism, in part, because it sold newspapers and appeared to justify higher government spending. There is also the inconvenient truth that climate scientists who produce papers and models showing a coming catastrophe are much more likely to receive government grants than those who say there is no big problem.
The Obama administration’s economic forecasts have been consistently wide of the mark in grossly overstating what is likely to occur. Its models use a Keynesian framework, which leads to overstatement of the benefits of government spending and an understatement of the costs of that spending. The models also have consistently underestimated the disincentives of higher taxes on labor and capital and the amount of regulatory-cost drag. If the model-builders corrected these persistent mistakes, they would produce results at odds with the president’s economic ideology — of which they are keenly aware. The president has a political agenda that includes a belief that global warming is a much bigger problem than it is likely to be, and that full employment and more rapid economic growth can only occur with a larger, more activist government.
There is also a long history of mathematical model-builders — whether their field is financial models, economic models or climate models — having much more faith in the results than are objectively warranted. Note the unusual frequency of so-called “Black Swan” events, which keep surprising model-builders with unforeseen events. Defenders of the government-funded models are always quick to point out the potential bias of models funded by private companies with a vested interest, which is fair. However, private-sector forecasters, whether independent or special-interest, compete with each other for accuracy, and those who prove to be the least accurate are quickly disregarded. Both history and an understanding of economic incentives ought to raise many more flags when models funded by taxpayers produce results that are in the perceived self-interest of the political class responsible for their funding. The safe bet is that the Intergovernmental Panel on Climate Change and the Obama administration will continue to produce greatly overstated climate and economic forecasts, and then attack those who voice a healthy skepticism as know-nothings.
EPA’s McCarthy admits regs are for show, not results
The Obama administration and its dutiful EPA have an ambitious plan to end millions of years of natural “climate change.” Meanwhile, as they determinedly demonstrate heroic world leadership to avert a looming non-disaster, the UN’s IPCC faces a different epic damage control challenge. As their political operatives meet in Stockholm this week to finalize their latest Summary for Policymakers report, they’ve got to figure out how to spin unsettling evidence of a 17-year “pause” in global temperature rise despite what they love to trumpet as “record high” atmospheric CO2 concentrations,
There are some other inconveniently non-alarming circumstances that the President, his agencies, and the UN are conveniently overlooking as well. For example, there’s that perplexing rapidly expanding Arctic sea ice; the lack of increase in the strength or frequency of landfall hurricanes in the world’s five main hurricane basins during the past 50-70 years; the lack of increase in the strength or frequency in tropical Atlantic hurricane development during the past 370 years; the longest U.S. period ever recorded without intense Category 3-5 hurricane landfall; and no trend since 1950 evidencing any increased frequency of strong (F3-F-5) U.S. tornadoes.
To discuss such matters, 13 federal agencies were invited to provide testimony about the Administration’s climate policy before the House Energy Committee on September 18. Only two accepted, providing EPA Administrator Gina McCarthy and Energy Secretary Ernest Moniz as witnesses.
A notable exchange occurred about 2 hours and 16 minutes into the hearing between McCarthy and Rep. Mike Pompeo (R-Kan.). My friend Marlo Lewis at the Competitive Enterprise Institute provided an unofficial transcribed version of this segment, which can also be viewed directly on Youtube.
Pompeo: Ms. McCarthy I want to ask a couple of questions of you. So one of the objectives today is to identify the greenhouse gas regulations that already existed and those in the future — how they actually impact the climate change, right? So you’d agree we want to have a successful climate policy as a result of those sets of rules and regulations that you promulgate? Fair base line statement?
McCarthy: In the context of a larger international effort, yes.
Pompeo: You bet. And on your website you have 26 indicators used for tracking climate change. They identify various impacts of climate change. So you would believe that the purpose of these rules is to impact those 26 indicators, right? So you put a good greenhouse gas regulation in place, you’ll get a good outcome on at least some or all of those 26 indicators.
McCarthy: I actually . . . I think that the better way to think about it, if I might, is that it is part of an overall strategy that is positioning the U.S. for leadership in an international discussion. Because climate change requires a global effort. So this is one piece and it’s one step. But I think it’s a significant one to show the commitment of the United States.
Pompeo: Do you think it would be reasonable to take the regulations you promulgated and link them to those 26 indicators that you have on your website? That this is how they impacted us?
McCarthy: It is unlikely that any specific one step is going to be seen as having a visible impact on any of those impacts — a visible change in any of those impacts. What I’m suggesting is that climate change [policy] has to be a broader array of actions that the U.S. and other folks in the international community take that make significant effort towards reducing greenhouse gases and mitigating the impacts of climate change.
Pompeo: But these are your indicators, Ms. McCarthy. So . . .
McCarthy: They are indicators of climate change, they are not directly applicable to performance impacts of any one action.
Pompeo: How about the cumulative impact of your actions? Certainly you’re acting in a way . . . you say these are indicators of climate change. Certainly it can’t be the case that your testimony today is that your cumulative impact of the current set of regulations and those you’re proposing isn’t going to have any impact at all on any of those indicators?
McCarthy: I think the President was very clear. What we’re attempting to do is put together a comprehensive climate plan, across the Administration, that positions the U.S. for leadership on this issue and that will prompt and leverage international discussions and action.
Pompeo: So you’re putting regulations in place for the purpose of leadership but not to impact the indicators that you, the EPA, says are the indicators of climate change? I’m puzzled by that.
McCarthy: Congressman we work within the authority that Congress gave us to do what we can. But all I’m pointing out is that much more needs to be done and it needs to be looked at in that larger context.
Pompeo: In 2010 with NHTSA [National Highway Traffic Safety Administration], in your opening statement you said you’ve gotten rid of about 6 billion metric tons [of greenhouse gases]. One of your indicators, for example, is heat-related deaths. How many heat-related deaths have been eliminated as a result of the 2010 NHTSA rules?
McCarthy: You can’t make those direct connections Congressman. Neither can I.
Pompeo: There’s literally no connection between the activities you’re undertaking and . . .
McCarthy: I didn’t say that.
Pompeo: Well, you said you can’t make the connections, so tell me what I’m not understanding. Can you draw a connection between the rules you’re providing, the regulations you’re promulgating, and your indicators? Or is it just . . .
McCarthy: I think what you’re asking is can EPA in and of itself solve the problems of climate change. No we cannot. But the authority you gave us was to use the Clean Air Act to regulate pollution, carbon pollution is one of those regulated pollutants, and we’re going to move forward with what we can do that’s reasonable and appropriate.
Pompeo: I’m actually not asking that question that you suppose that I’m asking. I’m not asking whether you have the power to solve greenhouse gases. What I asked was: Is anything you’re doing, doing any good? As measured by the indicators that you’ve provided. Is your testimony that you just have no capacity to identify whether the actions EPA has undertaken has any impact on those indicators? Literally, this is about science — cause and effect. Is there any causal relationship between the regulations you promulgated and the 26 indicators of climate change that you have on your website?
McCarthy: The indicators on the website are broad global indicators. . .
Pompeo: They’re not broad, they’re very specific.
McCarthy: . . .of impacts associated with climate change. They are not performance requirements or impacts related to any particular act.
Pompeo: I actually like the indicators — they’re quantifiable, right? Heat-related death, change in ocean heat, sea-level rises, snow cover — those are very quantifiable things. But now you’re telling me . . .
McCarthy: They indicate the public health associated with climate change.
Pompeo: Exactly, but you’re telling me you can’t link up your actions at EPA to any benefit associated with those quantifiable indicators that the EPA itself has proposed as indicative of climate change.
McCarthy: I think what we’re able to do is to show — and I hope we will show this in the package that we put out for comment — is what kind of reductions are going be associated with our rules, what we believe they will have in terms of an economic and a public health benefit. But it is again part of a very large strategy.
Pompeo: My time has expired.
So there you have it. Regardless of the countless billions of taxpayer and consumer dollars being spent to wage war on natural and inevitable climate change, the EPA head is unable to identify any discernible health and welfare benefits of her agency’s draconian regulatory policies. Instead, the apparent goal of the EPA’s current and proposed greenhouse gas regulations is to persuade the international community, particularly China, India, and other developing nations, to follow the Obama administration’s U.S. leadership over an economic precipice.
Let’s finally get it straight. Carbon dioxide isn’t a dangerous “pollutant”… it’s a natural and essential plant food. The real dangers to public health and welfare are the economic destruction, job elimination, and escalating costs of food, energy, and other essentials resulting from scientifically unwarranted policies. The greatest burdens of such sophistry fall upon those who can least afford them.
Gullible Green sailors trapped in the Arctic
The naïve advice of ardent activists can kill. Last spring, Paul Beckwith of Sierra Club Canada predicted that the Arctic seas would be ice-free ice this summer. (So did Britain’s BBC network.) This exciting adventure opportunity attracted a variety of yachts, sailboats, rowboats, and kayaks owners to try sailing the fabled Northwest Passage.
As a former sailboat owner I can understand their excitement, but my heart aches for the agonies they now face. The Arctic sea ice suddenly expanded 60 percent this fall, after the coldest summer in the modern Alaska temperature record. The passage is now impassable. More than a dozen of the boats are trapped, apparently even including a group of tiny American jet-ski “personal watercraft” that were attempting to cross from the east coast of Russia to the North Atlantic. Arctic observers are now warning that even Canadian icebreakers might not be able to rescue them.
The Northwest Passage blog reminds us that fall super storms are a potentially deadly fact in Alaska. “It is only a matter time. . . . Give Mother Nature her due time and she will move billions of tons of sea ice and push it up against the Alaska Arctic coast—effectively closing the door to exit the Arctic ice from western Canada. . . . No icebreakers are going to be able to offer any assistance. Mother Nature is mightier than all the icebreakers put together.” Note that the Atlantic exit is already problematic.
Helicopter rescues on Arctic ice are incredibly expensive, involving hundreds of miles of flying by copters and crews expensively maintained in that icy and sparsely populated region. Additionally, all the lovely boats become write-offs.
The boaters ignored major warning signs. The planet has not warmed appreciably in at least 15 years. NASA told us in 2007 that the Pacific Ocean had shifted into the cool phase of its 60-year cycle and that fact predicted cooler winters until 2030.
Most concerning of all is that the costs of an Arctic sailing mistake are horrendous. Wonderfully preserved hulks of sunken explorers’ ships litter the sea-bottom around the Northwest Passage. Some of the vessels that survived the ice were trapped for as long as three winters. At least one sailboat recently froze into the ice near Svalbard. The captain and his boat were buried under the heavy snow, 100 miles from human habitation. (He actually survived to write a book.)
The risks run by the Arctic boaters are obvious. Modern society is running less obvious risks based on the same sort of naïve advice coming from the Sierra Club, Greenpeace, the Intergovernmental Panel on Climate Change, and a host of like-minded “saviors of the planet.” What about the poor and elderly Britons and Germans who have frozen to death in their homes because they couldn’t afford the higher costs of gas and electricity imposed by “renewable fuels”?
What about the millions of Third World mothers and children who die of lung diseases every year as it is politically incorrect to give them access to tiny amounts of kerosene for heating and cooking. The alternative is burning dung and charcoal in indoor, poorly ventilated fires.
Closer to home, what about the millions of young Americans who can’t get jobs in an economy stalled by overpriced “Green” energy and investor uncertainty over the War on Coal? Inevitably, being gullible carries a price tag. We are just beginning to realize how expensive the naïveté of the environmental movement has become.
David Suzuki Attacks Climate Science
David Suzuki, better known in Canada than in the U.S. and other parts of the world, is a former scientist and modern-day financier of the radical fringes of the environmental movement. In a widely circulated essay, he criticizes media outlets ranging from Canada’s Financial Post to the Washington Post in the U.S. for daring to cover the scientific debate over the causes and consequences of climate change.
He also singled out and attacked three scientists who led a team of nearly 50 scientists who wrote or contributed to a report, titled Climate Change Reconsidered II: Physical Science, released earlier this week by my organization, The Heartland Institute.
Why would a former scientist attack scientists for doing exactly what good scientists have always done, which is to question theories and predictions based on fear and ignorance rather than facts and reason? Why does Suzuki criticize the press for doing what good journalists ought to do, which is cover both sides of debates over issues with serious consequences for public policy?
Let me be clear: Suzuki is not speaking as a scientist. He spent so little time looking at the report he criticizes that he mis-identifies the organization that produced it: It is the Nongovernmental International Panel on Climate Change (NIPCC), not the International Climate Science Coalition. (The Heartland Institute published the report for NIPCC).
Suzuki mistakenly says the 1,000-page report was not peer-reviewed. In fact it was doubly peer-reviewed. Nearly all of the 4,000-plus sources it cites originally appeared in peer-reviewed journals, and the volume itself was put through peer review by the three lead authors. The reviewers are clearly identified in the report and in its Summary for Policymakers (SPM).
While Suzuki failed to read the report and SPM that are available for free online (at www.climatechangereconsidered.org), he’s happy to endorse without qualification a report that hasn’t yet been written: the United Nations Intergovernmental Panel on Climate Change’s fifth assessment report, which he says “is a review of all the available science on climate change.”
Of course he has not compared the sources cited in the yet-to-be-published IPCC report and those cited in the NIPCC report. So how does he know the IPCC report reviews “all of the available science”? He obviously does not.
David Suzuki epitomizes what is wrong with the environmental movement today. It embraces positions without critical thought and regardless of the actual scientific evidence, so long as those positions appear to advance its political agenda. It attacks and demonizes anyone, even scientists, who dare to point this out. Until environmentalists publicly rebuke and distance themselves from irresponsible demagogues like David Suzuki, the movement will continue to lose the public support it once had.
