That Arctic Has Been Astonishingly Warm

This is an astonishing graph:

The Arctic is currently about 17°C (31°F) degrees above normal. The baseline (green line) is the 1958-2002 average. 

If that were happening where I live, today's high would have been 86°F. Normal high (1981-2010) for Salem, Oregon today is 53°F.

Reflecting this, Arctic sea ice has already reached a record low for the year, 2.5% below last year's record low.
