North Pole: Temperatures climb above zero degrees CLIMATE meteorological measurements reveal temperatures of twenty degrees above seasonal averages North Pole ..

Un ours polaire sur la banquise.
Hot shot on the North Pole. Temperatures between 0 and 2 degrees Celsius were measured there Wednesday. It's twenty degrees above seasonal norms. These exceptionally mild temperatures are due to a "powerful and violent" depression that affects the North Atlantic under Canadian weather services.

This depression has informed eastern Canada a Christmas unusually hot (15.9 degrees Celsius on December 24 in Montreal for close to seasonal averages -10 degrees), before winning the North Atlantic Ocean.
Currently focused on Iceland, this weather phenomenon has reduced the pressure of air at 928 hectopascals and winds led to 140 km / h and waves of 15 meters high. "This deep depression advancing warm air to the North Pole, where temperatures are at least greater than 20 degrees C compared to the normal" lying "around the freezing point 0, 1 and 2 degrees "said Natalie Hasell, meteorologist at the Canadian Ministry of the Environment.

US scientists from the North Pole Environmental Observatory (NPEO) found that the mercury had climbed sharply the past two days, from -37 ° C Monday at -8 ° C Wednesday on a tag located in the Arctic about 300 km from the North Pole, said James Morison, a researcher at NPEO.
Capital of Inuit territory of Nunavut, northeast of Canada under the Arctic Circle, Iqaluit recorded at Christmas temperatures of -4.6 ° C and -4.9 ° C, -21 ° C against average of never seen again. Baffin Island, on which is Iqaluit, even experienced rains in December, said David Phillips, meteorologist at the Canadian Ministry of the Environment. "This is probably El Niño who ventures to the North," said he has about this weather phenomenon that occurs every four to seven years on average.
The Arctic is the region most affected by global warming globe, now with higher temperatures of three degrees minimum compared to pre-industrial times, according to international institutes. Resulting more frequent snowfalls, stronger winds and a steady decline in ice for over 30 years.
One consequence of global warming?
It would be too early to link the mild temperatures observed at the end 2015 at the North Pole global warming, warned Natalie Hasell, noting that meteorologists based their conclusions did not "a single fault". Especially since the Canadian National Meteorology has no records of temperatures on the roof of the Earth, she said.
However, "it's really weird to have temperatures around zero late December at the North Pole," she noted, stressing that depression, with warmer temperatures would move in the coming days to the Siberia in northern Russia.
