Jman, that is an utterly naive statement. All scientific data shows that the earth has warmed over the past 100 years. Almost every major climatologist agrees that the world is warming and warming more rapidly than any time we have observed (based on atmospheric observations and ice cores from Greenland and Antarctica.) The ONLY thing up for debate, is that whether or not the change is anthropomorphic or not.
Here are a few linkshttp://www.koshland-science-museum.o...storical03.gifhttp://www.sustainablescale.org/imag...0AND%20CO2.JPG
Now based on these observations I, as a scientist cannot come to any other conclusion other than there is a direction correlation between human activities and atmospheric CO2 concentration and therefore global atmospheric temperatures.
NPR's Science Friday did a great story on this last week.http://www.npr.org/templates/story/s...toryId=5231582
The best part was when Eugene Linden pointed out that Naomi Oreskes 700 papers not 1 took issue with if humans were the cause of global warming. ( http://www.sciencemag.org/cgi/conten.../306/5702/1686
) The problem is the few scientists that don't believe that global warming in human influenced have wielded dis-proportional political influence in Washington. If you remove those scientists that have links to the fossil fuel industry, there are almost no scientists that disagree with the assertion that climate change is human caused.
|For example, while discussing a major U.S. Environmental Protection Agency report on the risks of climate change, then-EPA administrator Christine Whitman argued, "As [the report] went through review, there was less consensus on the science and conclusions on climate change" (1). Some corporations whose revenues might be adversely affected by controls on carbon dioxide emissions have also alleged major uncertainties in the science (2). Such statements suggest that there might be substantive disagreement in the scientific community about the reality of anthropogenic climate change. This is not the case.
So you can believe Michael Creighton, a science fiction writer, you can believe the lobbyists with ties to the fossil fuel industry or you can believe the hundreds of climatologists who have devoted their lives to this topic. I know who I trust....
