20 years later, a Greenland glacier is finally growing 00:57

(CNN)Greenland’s largest and most critical glacier, Jakobshavn, is gaining ice, according to NASA researchers.

Although this finding is surprising and temporarily good news for the glacier, limiting its contribution to sea level rise, the reason for the ice accumulation might spell disaster in the long run.
For two decades, Jakobshavn sustained remarkably consistent thinning that scientists thought would continue, if not accelerate, due to large-scale warming of the polar atmosphere and oceans — but that rate dramatically slowed in 2014, and the glacier actually thickened between 2016 and 2017 and again between 2017 and 2018, according to a study published Monday in the…
