Tornadoes are not increasing. Storms and droughts do not show any pattern of increasing or decreasing. . . . Variations of climate have always occurred, even when humans could not have had any impact. We don't know whether temperatures will continue to rise, whether human intervention has anything to do with the increase, and whether cutting greenhouse emissions will significantly cut temperatures. It has done both, and that doesn't say that it's due to carbon dioxide.
Sensitivity is fine, but getting the facts is even better.
Adopting Kyoto or branding carbon dioxide a pollutant would be disastrous to the world economy. Sorry, but sometimes Jane Fonda needs to be grossed out.
