Excellent post on global warming
This is a good post, blowing big holes in many of the arguments used by climate change deniers. It includes some very nice graphs. Post begins:
The Australian continues to display its contempt for science, scientists and the scientific method. They’ve published this piece of AGW denial by David Evans. Last time I looked at Evans he was saying that new evidence since 1999 had changed his mind about global warming, with this new evidence including the fact that the world had cooled from 1940 to 1975. Apparently this was too silly even for the Australian, so he now offers us four alleged facts.
1 The greenhouse signature is missing. We have been looking and measuring for years, and cannot find it.
Each possible cause of global warming has a different pattern of where in the planet the warming occurs first and the most. The signature of an increased greenhouse effect is a hot spot about 10km up in the atmosphere over the tropics.
This couldn’t be more wrong. Study the graphs below (from RealClimate). The left one shows the pattern predicted for doubling CO2, while the right one shows the pattern for a 2% increase in solar output.
Much more at the link. Read it all.
