I believe this testimony and its associated links is the best aggregation of data suggesting that that it is very premature of the world to decide that it needs to jump on Al Gore's bandwagon and make massive efforts to attempt to lower the earth's temperature.
Numerous peer-reviewed studies, analyses and prominent scientists continue to speak out to refute many conclusions of the IPCC. I have documented in the past how the consensus on the “science is settled” debate has been challenged, and in many cases, completely refuted, from the hockey stick, to the Stern Review, to the IPCC backtracking on conclusive physical links between global warming and observed hurricane frequency and intensity. Just this past week, a major new study was published in the peer-reviewed journal Climate Dynamics that finds worldwide land warming has occurred largely in response' to oceans, and not carbon dioxide. There have also been recent challenges by Russian scientists to the very idea that carbon dioxide is driving Earth’s temperature and a report from India challenging the so-called “consensus.” The Physics and Society Forum, a unit within the American Physical Society, published a new paper refuting the IPCC conclusions where the editor conceded there is a ‘considerable presence' of global warming skeptics within the scientific community. More and more prominent scientists continue to speak out and dissent from man made global warming. In June, the Nobel Prize Winner for Physics, Ivar Giaever, declared himself a “skeptic” and said “global warming has become a new religion.” Atmospheric Scientist Dr. Joanna Simpson, the first woman in the world to receive a PhD in meteorology also dissented in 2008. “As a scientist I remain skeptical” of climate fears, Dr. Simpson said in February of this year. In June, a top UN IPCC Japanese Scientist, Dr. Kiminori Itoh, turned on the IPCC and called man-made global warming fears the “worst scientific scandal in the history.” In addition, more evidence of challenges to global warming occurred when two top hurricane scientists announced they were reconsidering their views on global warming and hurricanes. As the normal scientific process continues to evolve and models continue to improve, there have many more instances documented that are positive developments, which should be embraced, rather than ridiculed or immediately attacked by the media or policymakers. It is my hope that as more and more of these researchers speak out, scientific objectivity and integrity can be restored to the field of global warming research.
Here is an excerpt from Senate testimony today by former NASA scientist Dr. Roy Spencer, Principal Research Scientist, Earth System Science Center University of Alabama in Huntsville
"On the subject of the Administration’s involvement in policy-relevant scientific work performed by government employees in the EPA, NASA, and other agencies, I can provide some perspective based upon my previous experiences as a NASA employee. For example, during the Clinton-Gore Administration I was told what I could and could not say during congressional testimony. Since it was well known that I am skeptical of the view that mankind’s greenhouse gas emissions are mostly responsible for global warming, I assumed that this advice was to help protect Vice President Gore’s agenda on the subject. […] Regarding the currently popular theory that mankind is responsible for global warming, I am very pleased to deliver good news from the front lines of climate change research. Our latest research results, which I am about to describe, could have an enormous impact on policy decisions regarding greenhouse gas emissions. Despite decades of persistent uncertainty over how sensitive the climate system is to increasing concentrations of carbon dioxide from the burning of fossil fuels, we now have new satellite evidence which strongly suggests that the climate system is much less sensitive than is claimed by the U.N.’s Intergovernmental Panel on Climate Change. […] If true, an insensitive climate system would mean that we have little to worry about in the way of manmade global warming and associated climate change. And, as we will see, it would also mean that the warming we have experienced in the last 100 years is mostly natural. Of course, if climate change is mostly natural then it is largely out of our control, and is likely to end -- if it has not ended already, since satellite-measured global temperatures have not warmed for at least seven years now. […] Based upon global oceanic climate variations measured by a variety of NASA and NOAA satellites during the period 2000 through 2005 we have found a signature of climate sensitivity so low that it would reduce future global warming projections to below 1 deg. C by the year 2100. […] Obviously, what I am claiming today is of great importance to the global warming debate and related policy decisions, and it will surely be controversial. These results are not totally unprecedented, though, as other recently published research6 has also led to the conclusion that the real climate system does not exhibit net positive feedback. […] I hope that the Committee realizes that, if true, these new results mean that humanity will be largely spared the negative consequences of human-induced climate change. This would be good news that should be celebrated -- not attacked and maligned. And given that virtually no research into possible natural explanations for global warming has been performed, it is time for scientific objectivity and integrity to be restored to the field of global warming research. This Committee could, at a minimum, make a statement that encourages that goal."
