Economist - The pause in climate change

The Economist has an article this week that talks about how the mystery of the pause in global warming may have been solved. The answer seems to lie at the bottom of the sea. The article talks about how over the past few years one of the biggest questions in climate science has been why, since the turn of the century, average surface-air temperatures on Earth have not risen, even though the concentration in the atmosphere of heat-trapping carbon dioxide has continued to go up. This “pause” in global warming has been seized on by those sceptical that humanity needs to act to curb greenhouse-gas emissions or even (in the case of some extreme sceptics) who think that man-made global warming itself is a fantasy. People with a grasp of the law of conservation of energy are, however, sceptical in their turn of these positions and doubt that the pause is such good news. They would rather understand where the missing heat has gone, and why—and thus whether the pause can be expected to continue.  A great article.
