Has Global Warming Stopped?

Whilst writing my review of Hot, Flat and Crowded, I had a quick look around for other reviews of the book. I managed to find this one from the right-wing Daily Telegraph.

Predictably it tows the paper's anti-green, climate sceptic line. But what really caught my attention was the reviewer claiming that "We have now experienced 10 years with no measurable 'global warming'". Oh really?!

It amazes me that people still repeat these sceptic claims parrot-fashion without giving any thought as to how easily they can be disproved.

This particular claim is based on 'cherry-picking' evidence i.e. chosing only data that fits the sceptic world-view and ignoring anything that undermines it. As the animated graph below demonstrates, sceptics simply select a small portion of the global temperature graph (in the above case: 2001 to 2010) that makes it appear that temperatures have not risen, completely ignoring not only the rest of the graph but the long-term trend.

Another case of sceptics trying to hide the incline.
