NASA doesn’t just search for life on other planets, its satellites also search the Earth for evidence of melting glaciers. Their "IceSat," which uses lasers to measure the thickness of ice, has discovered that Arctic ice is vanishing 50% faster than expected–at a rate of almost 500 cubic miles per year, since 2004.The Arctic is warming much faster than the rest of the planet.
On BBC News, Roger Harrabin quotes climate researcher Seymour Laxon as saying, "We have to be cautious until our data has been properly analyzed as part of a climate model, but this does suggest that the Arctic might be ice-free in summer for a day at least by the end of the decade.
Greenland isn’t the only place where glaciers are in trouble: While the TOP of the Earth is melting, the BOTTOM of the Earth–the Antarctic–is in trouble too. The polar regions are the most sensitive places on Earth to climate change, so what happens in Antarctica affects the entire Earth, in ways that we have yet to completely understand.
Is the horror of the "Creature From the Black Lagoon" in our future? As our planet warms and our glaciers melt, the world that is now locked away in permafrost will come alive. They’ll be tiny, so they won’t be obviously menacing, but they WILL start churning out greenhouse gases, making global warming worse.
