Whitehouse is not making a radical claim. He's just not putting the same spin on the facts that you'll find in most media reports about temperature trends. A recent BBC report (not by Whitehouse) has a chart showing 1998 was warmer than any year since and 6 years in that period were slightly warmer than 2007. Their spin is that the 2007 temperature shows that global warming is a confirmed trend. Um, well, on one hand 2007 didn't return the world to cooler temperature levels from earlier decades. But on the other hand the amount of carbon dioxide in the atmosphere has gone up a lot since 1998. So why hasn't the average global temperature for 2007 easily beat the 1998 number? (not trying to imply an answer btw - I'm just full of questions)

So maybe atmospheric carbon dioxide (CO2) buildup really has a warming effect. But that warming effect is getting offset by a cooling effect caused by less solar radiation.
