Uhm, About That Forecast

Jeff Jacoby points out that forecasts for a hot year in 2007 were off -- substantially. "In fact, 2007's global temperature was essentially the same as that in 2006 - and 2005, and 2004, and every year back to 2001. The record set in 1998 has not been surpassed. For nearly a decade now, there has been no global warming. Even though atmospheric carbon dioxide continues to accumulate - it's up about 4 percent since 1998 - the global mean temperature has remained flat. That raises some obvious questions about the theory that CO2 is the cause of climate change."

I'm open to suggestions on how to vet this data. The global mean of so many measurement locations may not be as significant as some regionalized values.
