Titus Andronicus writes "Angela Fritz and Jeff Masters of Weather Underground analyze this year's record ongoing Arctic ice melt. Arctic sea ice extent, area, and volume are all at record lows for the post-1979 satellite era. The ice is expected to continue melting for perhaps another couple of weeks. Extreme sea ice melting might help cause greater numbers of more powerful Arctic storms, help to accelerate the melting of the Greenland ice sheet, and help to accelerate global warming itself, due to the increased absorption of solar energy into the ocean."
We warn the reader in advance that the proof presented here depends on a
clever but highly unmotivated trick.
