It’s Cold All Over

Earth Observatory: Arctic Oscillation It’s not just Europe: NASA’s Earth Observatory provides the same data mapped to a polar projection of the entire northern hemisphere: “This image illustrates how cold December was compared to the average of temperatures recorded in December between 2000 and 2008. Blue points to colder than average land surface temperatures, while red indicates warmer temperatures.” It all has something to do with something called the Arctic Oscillation. (Before you start making cracks about global warming — i.e., what global warming? — take a good look at Greenland’s temperatures. Things will get very interesting if that ice cap melts.)
