Sea ice in Arctic shrinks to second lowest level on record
WASHINGTON- Arctic sea ice this summer shrank to its second lowest level since scientists started to monitor it by satellite, with scientists saying it is another ominous signal of global warming.
The National Snow and Ice Data Center in Colorado said the sea ice reached its summer low point on Saturday, extending 1.6 million square miles (4.14 million square kilometers). That's behind only the mark set in 2012, 1.31 million square miles (3.39 million square kilometers).
Center director Mark Serreze said this year's level technically was 3,800 square miles (10,000 square kilometers) less than 2007, but that's so close the two years are essentially tied.
