hondo77 writes: On Tuesday, the National Oceanic and Atmospheric Administration released its official assessment of December, January, and February's temperatures across the United States, and the results are striking: Not a single state in the U.S. had a cooler than average winter. (NOAA treats Alaska and Hawaii separately, due to shorter weather data records there -- though both states were significantly warmer than normal this winter. Weather records for the contiguous United States go back to 1895.) NOAA blames the recent warm weather on a record-strength El Nino "and other climate patterns," most notably, global warming. As a whole, this winter in the lower 48 was about 4.6 degrees Fahrenheit warmer than the 20th century average: a sharp contrast to the previous back-to-back frigid polar vortex winters, especially in the Northeast.
