Nature is not static, but causes its own, internally-generated changes - both in climate and in biological systems.

Believe it or not, very little research has ever been funded to search for natural mechanisms of warming... it has simply been assumed that global warming is manmade. Climate change - it happens, with or without our help.

Man-made global warming was a potential serious threat, and NASA wanted Congress to fund new satellites to study the problem. It was a team effort to get that accomplished.

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.

Temperature measurements in the arctic suggest that it was just as warm there in the 1930's...before most greenhouse gas emissions. Don't you ever wonder whether sea ice concentrations back then were low, too?

Twice I have testified in congress that unbiased funding on the subject of the causes of warming would be much closer to a reality if 50% of that money was devoted to finding natural reasons for climate change.

It is well known that strong to violent tornado activity in the US has decreased markedly since statistics began in the 1950s, which has also been a period of average warming. So, if anything, global warming causes FEWER tornado outbreaks...not more. In other words, more violent tornados would, if anything, be a sign of 'global cooling,' not 'global warming.'
