‘Devastating’ Arctic warming of 9-16°F now ‘locked in,’ UN researchers warn

“As the report explains, warming in the Arctic is occurring at least twice as fast as warming across the planet as a whole, thanks to Arctic amplification. One reason for this amplification is that  when highly reflective snow and ice melts due to higher temperatures, it is replaced by the dark blue sea or darker land, both of which absorb more solar energy than they reflect, leading to more melting.”
