humans are responsible for climate change

The U.S. Climate Change Science Program says that there are NOT discrepancies in rates of warming. As the Post noted, "the observed patterns of change over the past 50 years cannot be explained by natural processes alone, nor by the effects of short-lived atmospheric constituents such as aerosols and tropospheric ozone alone."

In other words, climate change IS being pushed by human actions. But no doubt Cheney-Bush, Exxon and others will still argue that the science isn't conclusive and will resist meaningful action, maybe only agreeing that climate change is a problem when St Louis is on the much-enlarged Gulf of Mexico. Oklahoma Senator Inhofe, who has called climate change the "biggest hoax in history," has already disputed the idea that this study confirms humanity's role in global warming.
