Cold Water Currently Slowing Fastest Greenland Glacier
(WorldNews Environment)

NASA research shows that Jakobshavn Glacier, which has been Greenland`s fastest-flowing and fastest-thinning glacier for the last 20 years, has made an unexpected about-face. Jakobshavn is now flowing more slowly, thickening, and advancing toward the ocean instead of retreating farther inland. The glacier is still adding to global sea level rise - it continues to lose more ice to the ocean than it gains from snow accumulation - but at a slower rate. The researchers conclude that the slowdown of this glacier, known in the Greenlandic language as Sermeq Kujalleq, occurred because an ocean current that brings water to the glacier`s ocean face grew much cooler in 2016. Water temperatures in the...
