A screaming lack of enthusiastic media coverage regarding recent evidence that Jakobshavn, the previously fastest-flowing, fastest-thinning glacier on Greenland’s west coast, has now gone rogue. Jakobshavn has represented the largest source of periodic ice mass loss over the last 20 years, and has produced about 10 percent of the country’s icebergs.
A study published last month in the journal Nature reported, "Here we use airborne altimetry and satellite imagery to show that since 2016, Jakobshavn has been re-advancing, slowing and thickening. We link these changes to current cooling in ocean waters in Disko Bay that spill over into Ilulissat Icefjord. Ocean temperatures in the bay’s upper 250 meters have cooled to levels not seen since the mid-1980s."
A major Greenland glacier that was one of the fastest shrinking ice and snow masses on Earth is growing again, a new NASA study finds.
The Jakobshavn glacier around 2012 was retreating about 1.8 miles and thinning nearly 130 feet annually. But it started growing again at about the same rate in the past two years, according to a study in Monday’s Nature Geoscience.
