• How much Arctic sea ice are you melting? Scientists have an answer

  

  Climate change may sometimes seem so big and abstract that it can be difficult to grasp the scope of the problem. But now, scientists have found a way to bring the numbers down to Earth: For every metric ton of carbon dioxide released into the air, three square meters of Arctic sea ice disappear. If you do the math, this means the average American is melting roughly 50 square meters of those frozen reserves every year.The findings, published in the journal Science, highlight the direct effect t..

• Maps can't accurately depict the earth's curved surface. But this one comes close

  

  It can be easy to forget, when looking at maps of the world, that the earth looks completely different. In flattening the curved surface of the earth, cartographers often sacrifice scale for size: Antarctica doesn’t stretch endlessly across the bottom of the earth, and China equals the size of the United States — including Alaska and Hawaii.But the AuthaGraph has tried to get closer to the earth’s curved reality: by angling the continents themselves.Hajime Narukawa at Keio University's Graduate..
