Plenty of Greenhouse Gas but No Warming

James M. Taylor is senior fellow for environment policy at The Heartland Institute and managing editor of Environment & Climate News. He has a column in Forbes in which he makes an interesting claim and poses a tough question to global warming "alarmists":
Global greenhouse gas emissions have risen even faster during the past decade than predicted by the United Nations Intergovernmental Panel on Climate Change (IPCC) and other international agencies. According to alarmist groups, this proves global warming is much worse than previously feared. The increase in emissions “should shock even the most jaded negotiators” at international climate talks currently taking place in Bonn, Germany, the UK Guardian reports. But there’s only one problem with this storyline; global temperatures have not increased at all during the past decade.

The evidence is powerful, straightforward, and damning. NASA satellite instruments precisely measuring global temperatures show absolutely no warming during the past the past 10 years. This is the case for the Northern Hemisphere mid-latitudes, including the United States. This is the case for the Arctic, where the signs of human-caused global warming are supposed to be first and most powerfully felt. This is the case for global sea surface temperatures, which alarmists claim should be sucking up much of the predicted human-induced warming. This is the case for the planet as a whole.

If atmospheric carbon dioxide emissions are the sole or primary driver of global temperatures, then where is all the global warming? We’re talking 10 years of higher-than-expected increases in greenhouse gases, yet 10 years of absolutely no warming.
Taylor does not object to what he calls global warming theory, but he does think the alarmists have gone too far with their extrapolations and concerns. His brief column offers some helpful data on this issue.
