Scientist skeptical of global warming

In an article by CNN, recently published Oct 24, 2007, there is a reference to a scientist by the name of Dr. Patrick Michael's who is skeptical of the severity of global warming on Greenland's' ice sheet; indirectly this assumes that he is also skeptical of how damaging anthropogenic sources of carbon are on the global warming trend. Another researcher by the name of Willie Soon (Bio and selected works) is a climate change "skeptic" as well. He works for the Harvard Smithsonian Center in Astrophysics, and has for some years criticized the largely agreed upon anthropogenic origins of global warming. In an article by NewScienitst it is noted that Soon receives funding for his research from Exxon-Mobil, which is analogous to Professor Deese's comment on cancer research and the tobacco industry in the late twentieth century. I recommend any one who is interested in this topic of science, skeptics, and global warming see this website.
