Global Warming on Dobbs now...

John Christy is the 'scientist' who says it's not real.

Anybody know anything about this guy?

Dr. John Christy is a climate scientist whose chief interests are Global Climate Change, Satellite Sensing of Global Climate, and Paleoclimate. He is best known, jointly with Dr. Roy Spencer, for his version of the satellite temperature record. He is a professor of atmospheric science and director of the Earth System Science Center at the University of Alabama in Huntsville (UAH). He was a key contributor to several IPCC reports, participating with lead authors in the drafting sessions, and in the detailed review of the scientific text. He was appointed Alabama's State Climatologist in 2000.

Christy is generally considered a contrarian on some global warming and related issues, although he helped draft and signed the American Geophysical Union statement on climate change <1>.


More recently, in an interview with National Public Radio about the new AGU statement, he said:

"It is scientifically inconceivable that after changing forests into cities, turning millions of acres into farmland, putting massive quantities of soot and dust into the atmosphere and sending quantities of greenhouse gases into the air, that the natural course of climate change hasn't been increased in the past century." <2>
Christy has also said that while he supports the AGU declaration, and is convinced that human activities are a cause of the global warming that has been measured, he is "still a strong critic of scientists who make catastrophic predictions of huge increases in global temperatures and tremendous rises in sea levels."

In May 2003 he was quoted as saying: "Will increases in CO2 affect the climate significantly? Are significant changes occurring now? Climate models suggest the answer is yes, real data suggests otherwise." <3>. Note that subsequent to this the "real data" has had to be revised, when Wentz et al. discovered errors in Christy's dataset: see satellite temperature record for details.


In December 2005, Christy was still arguing against the possibility that the increase in global temperature is man-made because his data showed the northern hemisphere was warming much faster than the southern hemisphere, eventhough carbon dioxide is spred evenly. "The most likely suspect for that is a natural climate change or cycle that we didn't expect or just don't understand."

in the northern hemisphere, and it's probably more than just the co2 causing the warming.

He pissed me off last week with what's-her-name.

spent a whole 7 minutes on it.

He does have a great poll asking if we should ditch electronic voting machines altogether.

currently - 85% yes

I just can't stand the "MSM" anymore.

Kevin Trenberth has been prominent in all aspects of climate variability and climate change research and is a leader in the Intergovernmental Panel on Climate Change assessments and in the World Climate Research Programme. Trenberth has published on many topics. Trenberth has evaluated many datasets and been the primary promoter of the need to reanalyze global data into fields in ways that meet climate requirements for continuity and consistency. He has determined the mass of the atmosphere as a fundamental physical quantity and how it varies as water vapor varies, and utilized the conservation constraint to evaluate datasets. One area of greatest impact has been in resolving outstanding issues concerning the global heat and energy budget of planet Earth. He has improved estimates of heat, energy and water transports within the atmosphere to a point where, when combined with top-of-atmosphere observed radiation, they now provide estimates of ocean heat transports as a residual that agree well with directly observed values. The work has proven vital for validating coupled atmosphere-ocean climate models and understanding heat flows that is so important in climate change. It has also provided a paradigm for the role of El Niño in the climate system, as heat is redistributed throughout the atmosphere and ocean system during the course of El Niño events. Trenberth recognized the importance of and was involved in El Niño research long before it became popular. Seminal contributions include identification of major decadal changes in El Niño and the 1976-77 "climate shift", and he correctly attributed tropical sea surface temperature changes and the 1988 La Niña as a cause of the 1998 North American drought. He has played a major role in determining the global water cycle and how it changes as climate changes, with particular foci on changes in precipitation frequency, intensity and amount, and thus on how droughts and floods change. He has been a leader of the development of the global climate observing system and the Global Earth Observations initiative.
