Climate Change Prediction: A Robust or Flawed Process?

By the Institute of Physics, September 2007

A key element in assessing climate change is the powerful computer simulations used to demonstrate how complex, interacting forcing agents influence the evolution of the climate system. Although the models are built around a long-accumulated understanding of the underlying physical processes and dynamics - and are compared with historical and contemporary observations - there are still many aspects that are less well understood. There is, therefore, a range of views about the reliability of using these models to make credible projections of our future climate.

At the seminar, two leading climate physicists, Prof. Richard S Lindzen, Alfred P Sloan Professor of Meteorology at the Massachusetts Institute of Technology (MIT), and Prof. Alan J Thorpe, chief executive of the Natural Environment Research Council (NERC), described the current status of climate-model prediction from rather different viewpoints. Prof. Lindzen explained the limitations of climate models and outlined why attempts to attribute global temperature rise to an increase in carbon dioxide (CO2) emissions were flawed. He maintained that there was no sound evidence that temperatures would rise substantially in the future. Prof. Thorpe based his presentation on the huge weight of evidence in the scientific literature, showing that current and future warming of the climate is caused by the human input of greenhouse gases. He presented a variety of evidence supporting the validity of current global models on which current concerns about global warming are based. He also stressed that more research was being done and needed to refine the details further. Read more here.

Controversial Virginia State Climatologist Pat Michaels Steps Down

By the Associated Press in the Daily Press

CHARLOTTESVILLE, Va. - Virginia’s state climatologist, whose doubts about global warming and utility-industry funding made him a lightning rod on climate change issues, quietly left his position over the summer.

Patrick J. Michaels, who had held the position since 1980, will remain as a part-time research professor on leave at the University of Virginia, Joseph C. Zieman, chairman of the school’s Department of Environmental Sciences, told The Daily Progress of Charlottesville. Michaels has been a leading skeptic of global-warming theories. While he believes global warming is real and influenced by humans, he contends it primarily is caused by natural forces. That view caused Gov. Timothy M. Kaine’s office to ask Michaels last year to refrain from using his title when conducting non-state business because of fears his views would be perceived as an official state position.

Michaels said he will continue to work at the libertarian-conservative Cato Institute in Washington, where he works while on leave from U.Va. “I feel I can speak more freely,” he said. Read full story here.


Icecap note: Icecap looks forward to Pat being free to express his opinion more openly. He has been an excellent spokesman for a more balanced view of climate change which has made him a target of those wishing to silence all opposing views.

Scientists Counter AP Article Promoting Computer Model Climate Fears

By Marc Marano, EPW Blog

Nearly two dozen prominent scientists from around the world have denounced a recent Associated Press article promoting sea level fears in the year 2100 and beyond based on unproven computer models predictions. The AP article also has been accused of mischaracterizing the views of a leading skeptic of man-made global warming fears. The scientists are dismissing the AP article, entitled “Rising Seas Likely to Flood U.S. History” as a “scare tactic,” “sheer speculation,” and “hype of the worst order.”

Prominent scientist Professor Nils-Axel Morner, declared “the rapid rise in sea levels predicted by computer models simply cannot happen.” Morner, a leading world authority on sea levels and coastal erosion who headed the Department of Paleogeophysics & Geodynamics at Stockholm University, noted on August 6, 2007: “When we were coming out of the last ice age, huge ice sheets were melting rapidly and the sea level rose at an average of one meter per century. If the Greenland ice sheet stated to melt at the same rate - which is unlikely - sea level would rise by less than 100 mm - 4 inches per century.” Morner, who was president of the INQUA Commission on Sea Level Changes and Coastal Evolution from 1999 to 2003, has published a new booklet entitled ”The Greatest Lie Ever Told,” to refute claims of catastrophic sea level rise.

Emmy Nominated Meteorologist Art Horn says AP loves ‘a scary story’ .“Fearless forecasts from people who likely have never made real time, real world predictions. We who have worked in the real world of everyday weather forecasting for decades understand what it’s like to be burned, even when you felt the forecast was a lock. I’m of the belief that most if not all of these predictions come from people who don’t know much about the nature of prediction,” Horn wrote to Inhofe EPW Press Blog the day after the AP article was published. “Working with computer models that don’t even start with a climate remotely similar to the real world can’t give you results that are in any way close to useful. But the AP and all news organizations love a scary story. I know, I worked as a TV meteorologist for 25 years. If it will generate a buzz they will run with it,” Horn explained. “Making predictions about how much sea level will rise helps to insure the money train will continue. There will be people in seats of power that will continue to feed money to universities, research facilities and people like [NASA’s] James Hansen.

Former Harvard physicist Dr. Lubos Motl writes: “There’s no good reason to expect more than 3 millimeters per year in average. It’s been really 1.5 mm in the last 50 years, and 2 mm per year in 1900-1950. The rate has actually slowed down according to some papers.” “Any model that predicts significant acceleration [of sea level] with growing CO2 is falsified or nearly falsified by the observed data. It’s crazy to think that this slow gradual rise is anything that would justify any actions besides the houses that have to be either moved or protected on the centennial scale,” he added. “Any calculation that wants to indicate that the effects of sea level rise are a significant portion of the life or the economy is simply a miscalculation,” he concluded.  Read what the other scientists have to say here.

Summary Conclusions of Climate Science

By Roger Pielke Sr. Climate Science Blog

In the final blog on Climate Science (we will miss your insightful blogs, Roger), Roger summarizes the conclusions he has formed on Climate Science.  Here are a few of them. See all of them here.

In terms of climate change and variability on the regional and local scale, the IPCC Reports, the CCSP Report on surface and tropospheric temperature trends, and the U.S. National Assessment have overstated the role of the radiative effect of the anthropogenic increase of CO2 relative to the role of the diversity of other human climate climate forcing on global warming, and more generally, on climate variability and change. Global and regional climate models have not demonstrated skill at predicting regional and local climate change and variability on multi-decadal time scales. Attempts to significantly influence regional and local-scale climate based on controlling CO2 emissions alone is an inadequate policy for this purpose.

Humans are significantly altering the global climate, but in a variety of diverse ways beyond the radiative effect of carbon dioxide. The IPCC assessments have been too conservative in recognizing the importance of these human climate forcings as they alter regional and global climate. These assessments have also not communicated the inability of the models to accurately forecast the spread of possibilities of future climate. The forecasts, therefore, do not provide any skill in quantifying the impact of different mitigation strategies on the actual climate response that would occur.

Climate Corrections

By Syun-ichi Akasofu Commentary in the Wall Street Journal

Climate change reared its head again last week at the Asia-Pacific Economic Cooperation summit in Sydney, where participating heads of state struggled to reach a consensus on how to reduce emissions of carbon dioxide (CO2). The political squabbling, global warming true believers will say, stands in stark contrast to the scientific consensus that the greenhouse effect, a product of increasing CO2 in the atmosphere, is causing dramatic climate change. There’s just one problem with this view: There’s a lot less to that “scientific consensus” than meets the eye.

Scientists have no clear knowledge of the cause of the Little Ice Age and of the subsequent rebound; or of the Big Ice Age; or of a warm period when the Arctic Ocean had no ice; or of the medieval warming period. In fact, IPCC scientists do not understand the causes of the rapid increase of temperature from 1910 to 1945; or the decrease from 1945 to 1975, when CO2 levels were rising. Without understanding these recent changes, it is premature for the IPCC to jump to the conclusion that CO2 is the main cause of the last 30 years of global warming.

Many people claim scientists proved the greenhouse effect with models run on supercomputers. But a supercomputer is not a crystal ball. Scientists merely enter observed (or expected) CO2 amounts into a computer and, using an algorithm, a projection emerges. No computer can accurately represent such a gigantic system as the Earth with all its unknown processes, such as the causes of the medieval warm period and the Little Ice Age. Therefore, no supercomputer, no matter how powerful, is able to prove definitively a simplistic hypothesis that says the greenhouse effect is responsible for warming.  Read full commentary here.  Read more on why supercomputers can’t be relied on here.

Climate Change is Nothing New!

By Lance Endersbee

The Earth, the Sun, and indeed the Cosmos, comprise an inter-acting, dynamic, and evolving system.  It is all in a state of continuing change.  There is no steady state.  In contrast, the IPCC assumes that the Earth was in a steady state until 250 years ago, which was upset by Man through increasing use of carbon fuels, and that led to atmospheric changes and consequential global warming.


The Sun is the dominating influence on the climate of the Earth.  That simple fact is not recognised by IPCC.  The Sun is a churning, quivering body of hot plasma, generating intense electromagnetic fields in space that envelop the Earth.  The electromagnetic behaviour of the Sun dominates and determines the electromagnetic and geotectonic response of the Earth, and thereby climate.

A key part of the IPCC report is the presentation of evidence of parallel increases in both global temperatures and levels of carbon dioxide in the atmosphere.  It is claimed by IPCC that the increased carbon dioxide emitted by Man is causing global warming.  In my paper it is shown that the cause and effect relation is exactly the opposite; that natural global warming has caused an increase in the level of carbon dioxide in the atmosphere, simply because of the reduction in solubility of carbon dioxide in sea water with increasing sea temperatures.

It’s Cool in Here

National Review Online, September 4, 2007

Bjorn Lomborg is back, and his critics will not be happy. In 2001, the Danish statistician published The Skeptical Environmentalist, an optimistic assessment of global environmental trends that provoked intense controversy and debate. His data-driven challenge to the “Litany” of environmental pessimism incited vitriolic attacks from environmentalist doomsayers. Malthusian environmental activists sought to discount his message, accusing Lomborg of “scientific dishonesty” and, in one case, throwing a pie in his face. Such tactics failed to accomplish anything but increase Lomborg’s notoriety and boost book sales.

If The Skeptical Environmentalist gave eco-pessimists epileptic fits, Lomborg’s new book could provoke outright seizures. Cool It: The Skeptical Environmentalist’s Guide to Global Warming is Lomborg’s take on the number one environmental issue of the day. Lomborg remains stubbornly optimistic about humanity’s future as he argues we must “cool our conversation, rein in the exaggerations, and start focusing where we can do the most good.” For Lomborg, this also means cooling the push for binding limits on greenhouse-gas emissions.

At times Lomborg’s discussion seems a bit technocratic, and he understates the degree of uncertainty inherent in climate-change policy. Estimates of future emissions and energy use patterns decades hence are highly suspect. So too are climate projections that are based on such uncertain inputs. This does not mean that climate-change concerns should be dismissed, but it does counsel against pretending cost-benefit analyses can be conducted with any degree of precision. Despite these flaws, Cool It is a highly valuable contribution to the climate-policy literature. In clear and concise prose, Lomborg diagnoses the problems plaguing contemporary climate policy, injecting a needed tonic of realism and common sense into the climate debate. And for that very reason, it is sure to make Lomborg’s critics hot-under-the-collar.

Thoughts on the Arctic Passage

By Gary Sharp, Scientific Director, Center for Climate/Ocean Resources Study

Read in this blog, the thoughts from Gary Sharp on the Arctic passage. We posted a recent story about Wrong Way Flanagan getting trapped in the arctic ice during an effort to be the first yachtsman to traverse the arctic in modern times to illustrate global warming. Although there will be stories about the melting of ice in the western arctic in the news, Gary discusses why this is not unusual historically. You will find some of his links fascinating and his stories about Joseph Fletcher inspiring. We hope to link to some of the videos and lectures of Dr. Fletcher on Icecap. See also Gary’s website Its All About Time here.

About arctic passages Gary notes “Joe pointed out several times to me in his B/W movies that there were seasons of nearshore ice-free situations - and others when skis or overflights were the only way in or out. Unfortunately - not enough years of observations - or guys with the right questions out there. Between 1956 and 1989 there were 33 passages. They are listed in the book Northwest Passage by Edward Struzik published in 1991. One was by K. Horie aboard the Japanese sloop Mermaid, who made an east to west passage in 1981-83. Another was by W. De Roos in a 42 foot ketch named Williwaw, who made the first single handed Passage in 1977 when the Northern Hemisphere was rather cold. Then, of course, there were all those US and Russian submarines cruising under the polar ice in the late 1950-90 Cold War period – that would occasionally find a hole – and pop up for a look-see.”
