"SOOT CAUSES 20% OF GLOBAL WARMING"

This is the latest pronouncement from the global warming scientists as can be seen from this article. The extraordinary thing is that in the 2007 IPCC report this was not mentioned. At that time they attributed all the warming to greenhouse gases. This suggests to me that these computer climate models may prove to be a tad inaccurate, which is what sceptices have been saying for some time.
