Arctic permafrost is thawing fast. That affects us all.

As the frozen ground warms much faster than expected, it’s reshaping the landscape—and releasing carbon gases that fuel global warming.

Craig Welch So, however fast well-intentioned policymakers think we need to move doesn't acct for this. And there are thresholds we don't want to cross. In other words: The best time to cut emissions? 30 yrs ago. Second best time: ASAP. Our story 100d

Craig Welch It’s not just that Arctic ground is thawing faster than expected. It’s that new research suggests it could release 2 to 3 times more carbon than once thought. And that msg isn’t in IPCC reports.yet. My new mag story w/amazing photos 101d

Craig Welch New studies say warming Arctic may release 2-3 times more carbon than thought, speeding #ClimateChange. So we may need to cut fossil fuels far faster. But IPCC reports don't include that data yet, so decision-makers may not even know. Our mag story 101d
