Ipcc Quotes

The manufactured consensus of the IPCC has had the unintended consequences of distorting the science, elevating the voices of scientists that dispute the consensus, and motivating actions by the consensus scientists and their supporters that have diminished the public's trust in the IPCC. ~ Judith Curry

The IPCC summary for policymakers is used to scare politicians and goad the public into action. The UN is all about politics. ~ Marc Morano

Not only is the Kyoto approach to global warming wrong-headed, the climate change establishment's suppression of dissent and criticism is little short of a scandal. The IPCC should be shut down. ~ Nigel Lawson

Under true peer-review ... a panel of reviewers must accept a study before it can be published in a scientific journal. If the reviewers have objections the author must answer them or change the article to take reviewers' objections into account. Under the IPCC review process, the authors are at liberty to ignore criticisms. ~ Richard Lindzen

At a recent conference, a colleague told one of us that in IPCC discussions, some scientists have been reluctant to make strong claims about the scientific evidence, lest contrarians "attack us". Another said that she'd rather err on the side of conservatism in her estimates, because then she feels more "secure." ~ Naomi Oreskes

It is quite obvious that the temperature change during the last 100 years or so includes significant natural changes, both the linear change and fluctuations. It is very puzzling that the IPCC reports state that it is mostly due to the greenhouse effect. ~ Syun-Ichi Akasofu

The world still awaits a proper inquiry into climategate: one that is not stacked with global warming advocates and one that is prepared to cross-examine evidence, interview critics as well as supporters of the CRU and other IPCC players, and follow the evidence where it clearly leads. ~ Ross McKitrick

You might want to check with the IPCC Bureau. I've been told that IPCC is above national FOI Acts. One way to cover yourself and all those working in AR5 [the upcoming IPCC Fifth Assessment Report] would be to delete all e-mails at the end of the process. Hard to do, as not everybody will remember it. ~ Phil Jones

The IPCC explicitly addressed - and rejected - the Marshall Institute argument for blaming the Sun. The upper limits on solar variability, they explained, are "small compared with greenhouse forcing and even if such a change occurred over the next few decades, it would be swamped by the enhanced greenhouse effect."75 ~ Naomi Oreskes

Perhaps the greatest scientific deception of the IPCC is the abuse and misuse of computer climate models. They allow them to make their reports and deliberations appear credible. They allow them to bamboozle the public because computer models are a complete mystery to most people. ~ Timothy Ball

All handling by IPCC of the Sea Level questions have been done in a way that cannot be accepted and that certainly not concur with modern knowledge of the mode and mechanism of sea level changes. ~ Nils-Axel Morner

The climatically inefficient and economically disastrous Kyoto Protocol, based on IPCC projections, was correctly defined by President George W. Bush as "fatally flawed". This criticism was recently followed by the President of Russia Vladimir V. Putin. I hope that their rational views might save the world from enormous damage that could be induced by implementing recommendations based on distorted science. ~ Zbigniew Jaworowski

The Intergovernmental Panel on Climate Change's (IPCC) new Summary for Policymakers is a political document that downplays assessments of uncertainty from the scientific reports. It omits much contrary evidence. In several cases, it even disagrees with the reports on which it is based. ~ Steven F. Hayward

I find the Doomsday picture Al Gore is painting - a six-meter sea level rise, fifteen times the IPCC number - entirely without merit ... I protest vigorously the idea that the climate reacts like a home heating system to a changed setting of the thermostat: just turn the dial, and the desired temperature will soon be reached. ~ Hendrik Tennekes

We have to be aware that the scientific community throws up tons of different hypotheses and at a certain point we'll find out who was right and who was wrong. But we have to go with the best information right now, which I would claim to be the IPCC reports. ~ Bjorn Lomborg

If you have a temperature rise, if it's a problem in one area, it's beneficial in another area. But sea level is the real 'bad guy,' and therefore they [The IPCC] have talked very much about it. But the real thing is, that [sea level rise] doesn't exist in observational data, only in computer modeling. ~ Nils-Axel Morner

The IPCC doesn't do any research itself. We only develop our assessments on the basis of peer-reviewed literature. ~ Rajendra K. Pachauri

The difference between the long-term average of the graph and the ice age, 12,000 years ago, is just over 3°C. The IPCC 2001 report suggests that the line of the hockey stick graph might rise a further 5°C during this century. This is about twice as much as the temperature change from the ice age to pre-industrial times. ~ James E. Lovelock

How could two teams of scientists come to such obviously contradictory conclusions on seemingly every point that matters in the debate over global warming? There are many reasons why scientists disagree, the subject, by the way, of an excellent book a couple years ago titled Wrong by David H. Freedman. A big reason is IPCC is producing what academics call "post-normal science" while NIPCC is producing old-fashioned "real science. ~ Joseph L. Bast

The same individuals who are doing primary research in the role of humans on the climate system are then permitted to lead the [IPCC] assessment! There should be an outcry on this obvious conflict of interest, but to date either few recognize this conflict, or see that since the recommendations of the IPCC fit their policy and political agenda, they chose to ignore this conflict. In either case, scientific rigor has been sacrificed and poor policy and political decisions will inevitably follow. ~ Roger A. Pielke

In my more than 60 years as a member of the American scientific community, including service as president of both the National Academy of Sciences and the American Physical Society, I have never witnessed a more disturbing corruption of the peer-review process than the events that led to this IPCC report. ~ Frederick Seitz

I can't see either of these papers being in the next IPCC report. Kevin [Trenberth] and I will keep them out somehow, even if we have to redefine what the peer-review literature is! ~ Phil Jones

Bring down Mike Mann and we can bring down the IPCC, they reckoned. It is a classic technique for the deniers' movement, I have discovered, and I don't mean only those who reject the idea of global warming but those who insist that smoking doesn't cause cancer or that industrial pollution isn't linked to acid rain. ~ Michael E. Mann

Every climate scientist has his or her own views on some issues that differ from the mainstream in detail. But the broad findings of the IPCC (Intergovernmental Panel on Climate Change) have general support amongst scientists with relevant specialist expertise. The broad wisdom of the IPCC is strongly contested by a small number, and a small minority, of reputed climate scientists. It is not contested by the large majority of specialists, and by the leaders of the relevant learned academies in the countries of great scientific accomplishment. ~ Ross Garnaut

The IPCC (Intergovernmental Panel on Climate Change, a group of more than 2,500 scientists) has provided the world community with first class assessments of the soaring temperatures the world is facing, the devastating impacts of these rises and the ways in which we can try and avoid the worst effects of global warming. We now know climate change is real and the hand of humankind in this warming is becoming clearer and clearer. ~ Klaus Topfer

The so-called scientific basis of the climate problem is within my professional competence as a meteorologist. It is my professional opinion that there is no evidence at all for catastrophic global warming. It is likely that global temperatures will rise a little, much as IPCC predicts, but there is a growing body of evidence that the errant behavior of the Sun may cause some cooling in the foreseeable future. ~ Hendrik Tennekes

I am withdrawing because I have come to view the part of the IPCC to which my expertise is relevant as having become politicized. In addition, when I have raised my concerns to the IPCC leadership, their response was simply to dismiss my concerns. ~ Christopher Landsea

We are now at the point in the age of global warming hysteria where the IPCC global warming theory has crashed into the hard reality of observations. ~ Roy Spencer

Keith's [Briffa] series ... differs in large part in exactly the opposite direction that Phil's [Jones] does from ours. This is the problem we all picked up on (everyone in the room at IPCC was in agreement that this was a problem and a potential distraction/detraction from the reasonably consensus viewpoint we'd like to show w/ the Jones et al and Mann et al series). ~ Michael E. Mann

A few weeks after the Climategate emails were released, Dr Sprigg spoke at the 13th Energy & Environment Expo in Phoenix177: Focusing closely on the Climategate scandal, in which leaked emails revealed IPCC gatekeepers hid, manipulated, and destroyed scientific data that contradicted claims of substantial human-induced global warming, Sprigg said the scandal has harmed the movement's scientific credibility. ~ Mark Steyn

Let me state what the official IPCC prediction is: Sea levels could go up as much as three-quarters of a meter in this century, but there is a reasonable probability it could be much higher than that. ~ Steven Chu

Although I am not a climatologist, it has been interesting to observe climatology from the point of view of an arctic scientist. In order for the field of climatology and IPCC to be healthy, I want to provide a few criticisms, which I hope are constructive. ~ Syun-Ichi Akasofu

The United States is strongly committed to the IPCC process of international cooperation on global climate change. We consider it vital that the community of nations be drawn together in an orderly, disciplined, rational way to review the history of our global environment, to assess the potential for future climate change, and to develop effective programs. The state of the science, the social and economic impacts, and the appropriate strategies all are crucial components to a global resolution. The stakes here are very high; the consequences, very significant. ~ George H. W. Bush

Earth has cooled since 1998 in defiance of the predictions by the UN-IPCC ... The global temperature for 2007 was the coldest in a decade and the coldest of the millennium ... which is why 'global warming' is now called 'climate change.' ~ Richard Keen

The many, many thousands of pages of the Assessment Reports of the UN's climate panel, the Intergovernmental Panel on Climate Change (IPCC), are the expression of the beliefs of a small circle of scientists and interested lobbyists who, against all evidence, have convinced themselves that humans are having a dramatic effect on the Earth's climate. ~ Alan Moran
