So Is It Spring Yet?

Many things are happening all around the world, but on the East Coast of the United States, it’s currently very warm. Very warm. Half-the-country-is-asking-whether-you-can-wear-shorts-to-work-in-February warm. This trend will continue as the century wears on, according to the Climate Impact Lab, a team of economists and climatologists from UC Berkeley, Rutgers University, the University of Chicago, and the Rhodium Group. They calculate that, between 1981 and 2010, Pennsylvania experienced an average of 105 days below freezing every year. But by the end of the 21st century, if greenhouse-gas emissions continue to grow, it will see only 50 days below freezing.
