Br-r-r! Where did global warming go? - The Boston Globe

"Carbon dioxide is not to blame for global climate change," Sorokhtin writes in an essay for Novosti. "Solar activity is many times more powerful than the energy produced by the whole of humankind." In a recent paper for the Danish National Space Center, physicists Henrik Svensmark and Eigil Friis-Christensen concur: "The sun . . . appears to be the main forcing agent in global climate change," they write.

Given the number of worldwide cold events, it is no surprise that 2007 didn't turn out to be the warmest ever. 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.
