"There’s finally no longer any debate about it. Yup, climate really does change, we humans almost certainly have some influence, Planet Earth has indeed experienced a continuing upward temperature trend for some time. And, oh yes, more than 97 percent of all scientists clearly agree with both of these statements. In fact, every single skeptical scientist that I know does.  Besides, all good scientists are supposed to be skeptical people." -  Larry Bell, writitng in *Forbes* magazine.
