It's all about peace and justice. Anti-war, yes, but more than that. It is about thinking for yourself, deinstutionalzing, taking the military out of the hands of corrupt leader. Together we can make it happen.

In Greenland, Ice and Instability

In Greenland, Ice and Instability

The changes seen in Greenland may turn out to be self-limiting in the short run; surging glaciers can flatten out and slow, for instance. Or they may be a sign that the island's ice - holding about the same volume of water as the Gulf of Mexico - is poised for a rapid discharge. Scientists are divided on that question, and on whether there is a near-term risk from a Texas-size portion of West Antarctica's ice sheet that is also showing signs of instability. This split divides those foreseeing a rise in the sea level of a couple of feet this century from water added by Greenland, West Antarctica and mountain glaciers, and a few experts who speak of a couple of yards in that time.
