The Arctic is warming REALLY fast


"... already this year, fires in the spring arrived earlier and with more ferocity, government officials have said. In the territory where Deyev lives, fires were three times as large this April as the year before. And the hot, dry summer lies ahead... 
“We always expected the Arctic to change faster than the rest of the globe,” said Walt Meier, a senior research scientist at the National Snow and Ice Data Center at the University of Colorado at Boulder. “But I don’t think anyone expected the changes to happen as fast as we are seeing them happen.”.. The temperatures occurring in the High Arctic during the past 15 years were not predicted to occur for 70 more years... 
Neither Dallas nor Houston has hit 100 degrees yet this year, but in one of the coldest regions of the world, Siberia’s “Pole of Cold,” the mercury climbed to 100.4 degrees Fahrenheit (38 Celsius) on June 20. 
Scientists have long maintained that the Arctic is warming twice as fast as the rest of the world. But in reality, the region is now warming at nearly three times the global average. Data from NASA shows that since 1970, the Arctic has warmed by an average of 5.3 degrees (2.94 Celsius), compared with the global average of 1.71 degrees (0.95 Celsius) during the same period. Scientists refer to the phenomenon as “Arctic amplification."
The melting of snow and ice earlier in the spring exposes darker land surfaces and ocean waters. This switches these areas from being net reflectors of incoming solar radiation to heat absorbers, which further increases land and sea temperatures."
