Meanwhile, as illustrated by above image, temperatures have been more than 1.5°C above pre-industrial levels for nine out of the past twelve months. For the months February and March 2016, the anomaly was actually quite close to the 2°C guardrail, while for station-only measurements, warming for February and March 2016 was well over the 2°C guardrail from pre-industrial levels.
The monthly warming in above image was calculated by using the NASA Global Monthly Mean Surface Temperature Change data (Land+Ocean) from 1880 through to September 2016, while adding 0.28°C to cater for the rise from 1900 to 1951-1980, and additionally adding 0.3°C to cater for the rise from pre-industrial to 1900.

As said, the top image has a further 0.3°C added to cater for the rise from pre-industrial to 1900, as discussed in an earlier post.
Above image shows sea surface temperature anomalies on the Northern Hemisphere, with a polynomial trend pointing at a doubling of ocean warming within one decade. Warming of the sea surface on the Northern Hemisphere threatens to speed up Arctic sea ice loss, as the Gulf Stream pushes ever warmer water toward the Arctic Ocean.
This further speeds up the demise of the snow and ice cover, which further accelerates warming of the Arctic Ocean and threatens to trigger huge eruptions of methane from its seafloor.
This could result in mass extinctions and destruction within a decade from now, as discussed at the extinction page.
The situation is dire and calls for comprehensive and effective action as described in the Climate Plan.
