Miami (AFP) Dec 12, 2017
A rapidly warming Arctic, where temperatures are rising twice as fast as the rest of the planet, is the "new normal," and the melting ice is triggering environmental changes that will affect the whole world, warned a global scientific report Tuesday. The Arctic is going through "an unprecedented transition in human history," that will accelerate sea level rise and boost the frequency of extreme weather events, said the Arctic Report Card, released annually by the US National Oceanic and Atmospheric ... read more
