U.S. experiences cold and heat extremes but-----but only the cold temps are being reported by the MSM.
Just a couple of weeks ago - record high temperatures here in Phoenix -- a heat wave in AK?
Climate change?
Opposites attract: U.S. experiences cold and heat extremes

While the continental U.S. shivered through an abnormally cold spell in December 2013, Alaska experienced record-breaking heat. Both extremes were caused by an unusual kink in the northern hemispheres polar jet stream, which caused frigid Arctic air to move south and warm air to head north.

Areas with warmer than average temperatures are shown in red; near-normal temperatures are white; and areas that were cooler than the 2000-2011 base period are blue. Note that Land surface temperatures (LST) are distinct from the air temperatures that meteorological stations typically measure. LSTs indicate how hot the surface of the Earth would feel to the touch. From a satellite vantage point, the surface includes a number of materials that capture and retain heat, such as desert sand, the dark roof of a building, or the pavement of a road. As a result, daytime land surface temperatures are usually higher than air temperatures.
