WASHINGTON (AP) 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).
"The trend is clear and ominous," National Center for Atmospheric Research senior scientist Kevin Trenberth said in an email.
Melting sea ice in the Arctic may change the jet stream and weather further south, especially in winter.
