A rapid and dangerous warming is underway in the Arctic.
This chart, based on results of work by Kaufman et al. (Science, 2009), shows how a long term cooling with low-level volatility has come to an abrupt end.
The years on the graph after 1915 are highlighted orange instead of blue. The dashed red line is a hundred year running average.
Data runs to 1995 and includes areas north of 60°N.
In the decade or so since the end of this reconstruction, temperatures have climbed higher still, and at an accelerating rate.
As many of you know, time is running out to prevent a runaway warming.
Below: 2 videos:
- One of the first videos I ever took (and without planning to): 2013 Washington Climate Rally; about 2 minutes.
- Jennifer Francis whose research on the connection between Arctic changes and global weather changes has been exceptionally useful and interesting; 40 minutes (with good audio quality).
