Arctic Speed-Melt Record


Although 2008 did not set a record for minimum sea ice it did set a record for speed melting. Arctic sea ice declined at a rate of 32,700 square miles a day in August. That’s about the size of Maine. Every day. And that’s compared to 24,400 square miles a day lost in August 2007—the record holder for minimum sea ice.

The 2008 results were surprising, says NASA, because last winter had near-normal ice cover. “We saw a lot of cooling in the Arctic that we believe was associated with La Niña,” says Joey Comiso of NASA’s Goddard Space Flight Center in Maryland. “Sea ice in Canada had recovered and even expanded in the Bering Sea and Baffin Bay. Overall, sea ice recovered to almost average levels. That was a good sign that this year might not be as bad as last year.”

But alas the sprint in August—the fastest-ever melt—undid the gains of the winter. Here’s what it looked like:

“Based on what we’ve learned over the last 30 years, we know that the perennial ice cover is now in trouble,” Comiso says. “You need more than just one winter of cooling for the ice to recover to the average extent observed since the measurements began. But the trend is going the other way. A warming Arctic causes the surface water to get warmer, which delays the onset of freeze up in the winter and leads to a shorter period of ice growth. Without the chance to thicken, sea ice becomes thinner and more vulnerable to continued melt.”

DOES IT FEEL LIKE POLITICS IS AT A BREAKING POINT?

It sure feels that way to me, and here at Mother Jones, we’ve been thinking a lot about what journalism needs to do differently, and how we can have the biggest impact.

We kept coming back to one word: corruption. Democracy and the rule of law being undermined by those with wealth and power for their own gain. So we're launching an ambitious Mother Jones Corruption Project to do deep, time-intensive reporting on systemic corruption, and asking the MoJo community to help crowdfund it.

We aim to hire, build a team, and give them the time and space needed to understand how we got here and how we might get out. We want to dig into the forces and decisions that have allowed massive conflicts of interest, influence peddling, and win-at-all-costs politics to flourish.

It's unlike anything we've done, and we have seed funding to get started, but we're looking to raise $500,000 from readers by July when we'll be making key budgeting decisions—and the more resources we have by then, the deeper we can dig. If our plan sounds good to you, please help kickstart it with a tax-deductible donation today.

Thanks for reading—whether or not you can pitch in today, or ever, I'm glad you're with us.
