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 Roy Spencer, for his version of the satellite temperature record.

Christy is generally considered a contrarian on global warming and related issues, although he helped draft and signed up to the American Geophysical Union statement on climate change [1].

But for a sample of his contrarian views: May 2003: "Will increases in CO2 affect the climate significantly? Are significant changes occurring now? Climate models suggest the answer is yes, real data suggests otherwise." [2]

Some people think he should no longer be considered skeptical of the global warming hypothesis, because of an interview with National Public Radio about the new AGU statement:

• Christy 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." [3]
• Christy also said that while he supports the AGU declaration, and is convinced that human activities are the major 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."
