Climate Study

A mathematical study of climate variability was done at the University of Wisconsin - Milwaukee and reported on the website of WISN.com. The researchers find that much if not all of the climate variability in the last 100 years can be explained by natural phenomena. They conclude:

If we don't understand what is natural, I don't think we can say much about what the humans are doing. We were very excited when we realized a lot of changes in the past century from warmer to cooler and then back to warmer were all natural.

Explain to me again why the President has appointed science advisers who are global warming true believers?
