Shocking New Stats Show ‘Arctic is Screaming’

The latest numbers suggest we’re approaching the point of no return on global warming. This according to a new piece at the Indianapolis Times.

In the arctic this summer, we lost 552 billion tons of ice. That’s 15 percent more than normal, the worst ever recorded and 12 percent more than the previous record. Enough water melted in Antarctica to cover Washington DC in water a half-mile deep.

The rapid melting has prompted some scientists to darken their predictions for an ice-free arctic. One group suggests ice-free summers by 2012. Another says ice will be gone entirely by 2040.

So what?

For one, an ice-free arctic will probably weaken Arctic blasts that bring moisture to the United States. Also, sea ice reflects 80 percent of the sun’s heat, thereby cooling the arctic. Water on the other hand absorbs 90 percent of the heat. “Warmer oceans then lead to more melting.”

Another way climate change eventually starts driving itself is when the permafrost just beyond the arctic (especially in Russia and Canada) starts to melt. “As the Earth warms, greenhouse gases once stuck in the long-frozen soil are bubbling into the atmosphere,”
reported USA Today last year.

About Me

My photo
I started pound360 to channel my obsession with vitamins, running and the five senses. Eventually, I got bored focusing on all that stuff, so I came back from a one month hiatus in May of 2007 (one year after launching Pound360) and broadened my mumblings here to include all science.
