> Here is a thought to keep in mind: the more extreme the weather anomaly, the less likely it is to be caused by human-induced (anthropogenic) global warming. The current situation is mega extreme in terms of our temperatures. The reason this aphorism makes sense is that global warming due to increased greenhouse gases should warm the earth in a progressive, slow way---not in huge jumps. Here in the Northwest, temperature increases have been particularly slow (about 1F over the past century) because of the huge thermal inertia of the Pacific Ocean.

> And there is something else: the warming influencing our region is localized and does not have the characteristics of the global warming signal seen in climate models. While the Northwest has been hot and dry, much of the eastern U.S. has been much cooler and wetter than normal. Even the Rockies have been wetter than normal. Global warming would warm them as well. This week I was at a weather conference in Chicago....it was quite chilly there at times.

I think this section, particularly the second paragraph, shows the writer has a very poor understanding of what global warming is and how it can and will have different localized effects across different timeframes.
