Global warming has reached a level such that we can ascribe with a high degree of confidence a cause and effect relationship between the greenhouse effect and observed warming.'It is already happening now.--James Hansen, 23 June 1988, Senate Testimony.

So, how has his claim held up?

He got it right according to climate scientists. If you are interested in the technical response of climate scientists see RealClimate. Definitely worth scanning because of the insights it provides into their thinking.
