Arctic Winter Warming

An unusually warm winter in Canada this year has delayed the opening of a 400-kilometer ice road that is rebuilt every year as the main conduit for Rio Tinto, Burgundy Mines , and De Beers to access their diamond mines in the remote Arctic region.

Even if the world were to cut emissions in line with the 2015 Paris Climate Change Agreement, winter temperatures in the Arctic would rise three to five degrees Celsius by 2050 and five to nine degrees by 2080, devastating the region and unleashing sea level rises worldwide, a new report by the UN Environment warned on Thursday.

The sun won't rise at the North Pole until March 20, and it's normally close to the coldest time of year, but an extraordinary and possibly historic thaw swelled over the tip of the planet this weekend. Analyses show that the temperature warmed to the melting point as an enormous storm pumped an intense pulse of heat through the Greenland Sea.

Arctic winter warming events are becoming far more frequent and long-lasting than they were three decades ago, due to human-driven climate change, a NASA study warns.

An arctic blast eased its grip on much of the eastern U.S. on Wednesday, with winds calming and the weather warming slightly.

The bitter chill gripping North America is a result of Arctic air that has spilled southwards, and global warming may be a cause.
