global temperature anomalies averaged from 2008 through 2012, NASA Goddard Institute for Space Studies |
The Arctic (red line above) clearly shows the strongest warming over time, while accelerating in recent years. The best fit for this warming in the Arctic is a fourth order polynomial trendline, as added to the data on the image below.
This accelerated warming in the Arctic is threatening to destabilize the methane in the seabed and trigger runaway global warming within a decade. Effective action needs to be taken before it's too late!
