Arctic Sea Ice Reaches All-Time Low

Climate scientists have more bad news about global warming. The extent of Arctic sea ice shrank to its smallest on record since satellite observation began in 1979, according to data from the National Snow and Ice Data Center. The ice sprawled to a maximum extent of 5.61 million square miles this past winter, which is 50,000 square miles less than the previous lowest maximum, which was recorded in 2011. Unless the Northern Hemisphere endures a cold spike, the maximum marks one of the earliest on record—15 days earlier than the average.
