We continue to be bombarded with scare stories about 'global warming' melting the arctic ice.
However, July, 2010, temperatures were among the coldest recorded. As I have pointed out numerous times, the problem in the arctic isn't temperatures. It is soot, largely from China, darkening the ice making it easier to convert sunlight to heat, thus accelerating melting.
Here is a very good article on the subject.
We can cut all the greenhouse gas we wish but it will have no effect if the problem is soot. It is vital to get cause and effect correct.
