Greenland Lurching Higher As Ice Melts

Image and caption courtesy NOAA’s Climate.gov Website.Southern Greenland saw an accelerated loss of ice amounting to a staggering 100 billion tons in 2010. As the weight of all that ice lifted, large portions of the island’s bedrock also rose a quarter of an inch or more higher.

That’s the finding of the Greenland GPS Network, a string of nearly 50 GPS stations on the Greenland coast designed to measure the bedrock’s response to accelerating loss of ice above.

Some GPS stations around Greenland routinely detect uplift of 0.59 inches/15 mm or more during the melt portion of the year. But the extremely warm temperatures of 2010 triggered a melting spike that lifted the bedrock as much as 0.79 inches/20 mm higher than usual in places.

Up to a point, this rebound might prove a useful counterpoint to sea-level rise.

SIX TRUTHS

Reclaiming power from those who abuse it often starts with telling the truth. And in "This Is How Authoritarians Get Defeated," MoJo's Monika Bauerlein unpacks six truths to remember during the homestretch of an election where democracy, truth, and decency are on the line.

Truth #1: The chaos is the point.

Truth #2: Team Reality is bigger than it seems.

Truth #3: Facebook owns this.

Truth #4: When we go to work, we're in the fight.

Truth #5: It's about minority rule.

Truth #6: The only thing that can save us is…us.

Please take a moment to see how all these truths add up, because what happens in the weeks and months ahead will reverberate for at least a generation and we better be prepared.

And if you think journalism like Mother Jones'—that calls it like it is, that will never acquiesce to power, that looks where others don't—can help guide us through this historic, high-stakes moment, and you're able to right now, please help us reach our $350,000 goal by October 31 with a donation today. It's all hands on deck for democracy.
