A high pressure system over Alaska enabled NASA to capture a rare satellite image of the state almost completely devoid of cloud cover, but the odd and unusually hot weather has some climate scientists concerned. Most days, the state is awash in clouds, which obscure much of Alaska’s 6,640 miles (10,690 km) of coastline and 586,000 square miles (1,518,000 square km) of land…According to Rutgers University climate scientist Jennifer Francis, the heat wave can be blamed on fluctuations in the jet stream. The jet stream usually flows more or less in a straight stream from east to west. But lately the jet steam has been bobbing and weaving up and down, which is associated with the extremes in weather.
