Today’s frigid winds notwithstanding, 2012 was the hottest year on record for Washington, Capital Weather Gang’s Matt Rogers reports: “The record will be broken by a landslide. With only a few days left in the year, D.C. should finish 1.3 degrees F warmer than the previous warmest year on record, 1991.” What’s that, you say? The year’s not over yet? Well, Rogers calculates, temperatures between Thursday and Monday “would have to average about 80 degrees below zero not to break the record.” The reasons are varied: In the short term, you can blame a negative Pacific Decadal Oscillation. In the longer view, urbanization and climate change are playing a big role.
