Global Warming

It seems to be quite fashionable to say that human-caused rises in greenhouse gases is causing global warming. (obviously there is global warming. The only question is the causes.) Take a look at this link. It is not so certain that we did it. It explains the science very thoroughly, and the conclusions are not too bad.

The total warming since measurements have been attempted is thought to be about 0.6 degrees Centigrade. At least half of the estimated temperature increment occurred before 1950, prior to significant change in atmospheric carbon dioxide levels. Assuming the unlikely case that all the natural drivers of planetary temperature change ceased to operate at the time of measured atmospheric change then a 30% increment in atmospheric carbon dioxide caused about one-third of one degree temperature increment since and thus provides empirical support for less than one degree increment due to a doubling of atmospheric carbon dioxide.

I am confused by the supposed consensus of scientists who agree with the pessimistic view. But then before Einstein, the Ether was a "scientific fact." (It had to be real, because light was a wave, and a wave had to be waving in some medium. The ether was the medium, but it was massless and undetectable.)

PS: I found out that Junkscience .com is a deceptive, politically conservative site. Read this criticism:

It seems like the future is never as bad or good as the predictions. (Where is my flying car?) I bet we will get by.
