Global Warming in a Few Slides

Dr. John Christy participated in a conference on global warming last month, and presented some power points that make several points with respect to the ongoing climate debate. All of these observations will be familiar to Power Line readers, but Dr. Christy’s visuals are effective. You can view the power point slides here, and the accompanying text here. The following are some of Christy’s slides.

Tornadoes are not becoming more frequent. On the contrary:

Snow cover in the northern hemisphere, where the most plausible claims of warming have been made, is not diminishing:

In the U.S., the climate is getting neither wetter nor dryer:

High temperature records are not being set with unusual frequency:

The climate models that are the only basis for warming alarmism are refuted by observation, and therefore are simply wrong:

And, finally, even if the U.S. were to adopt unrealistically harsh measures to restrict carbon output by impoverishing Americans, the effect on the Earth’s climate–assuming the models are right–would be close to zero:

Global warming alarmism is, in my opinion, the worst scientific fraud in world history.
