Antarctica Is Melting, After All

A while back, I blogged about how global warming skeptics were all smug and glowy (and wrong) about how Antarctica’s not melting. If the sea ice in the South Pole is actually increasing, the reasoning went, then how could the planet be warming? Huh? Huh? Well, for a number of reasons, that logic is false, but guess what? It may be moot point anyway, since it turns out that the western part of Antarctica is melting—and fast: Ice loss in the region has increased by 75 percent over the past ten years.

A team of researchers led by scientists from UC Irvine discovered that the underlying cause for the melting was accelerated glacier flow, which is, in turn, caused by warming oceans. All that melting means higher sea levels:

They detected a sharp jump in Antarctica’s ice loss, from enough ice to raise global sea level by 0.3 millimeters (.01 inches) a year in 1996, to 0.5 millimeters (.02 inches) a year in 2006.

That level of melting puts western Antarctica almost on par with Greenland, a dubious distinction, to say the very least.

DEMOCRACY DOES NOT EXIST...

without free and fair elections, a vigorous free press, and engaged citizens to reclaim power from those who abuse it.

In this election year unlike any other—against a backdrop of a pandemic, an economic crisis, racial reckoning, and so much daily crazy—Mother Jones' journalism is driven by one simple question: Will America will move closer to, or further from, justice and equity in the years to come?

We can’t do it without the support of readers like you, and we need to give it everything we've got between now and November. Thank you.
