Significantly, what happens in the Arctic does not stay in the Arctic. Arctic amplification drives more extreme weather in North America, while accelerating the defrosting of carbon-rich permafrost, which releases CO2 and methane that each cause faster warming — a dangerous amplifying feedback.
Earth’s melting permafrost threatens to unleash a dangerous climate feedback loopNew permafrost study underscores the critical importance of ambitious climate targets, like the Paris agreement.
In addition, as the sea ice disappears and Arctic warming speeds up, that causes faster melting of the land-based Greenland ice sheet, which in turn causes faster sea level rise. A recent study found that Greenland ice mass loss has tripled since 1997.So perhaps it’s not totally surprising that, as the Washington Post reported, “Scientists just found a strange and worrying crack in one of Greenland’s biggest glaciers.”
The implications of the ice cracking up at an accelerating rate are terrifying for humanity. The images created by it are haunting.
