Greenland Ice sheet growing since 2016

Jakobshavn Isbrae has been the single largest source of mass loss from the Greenland Ice Sheet over the last 20 years. During that time, it has been retreating, accelerating and thinning. 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 concurrent cooling of ocean waters in Disko Bay that spill over into Ilulissat Icefjord. Ocean temperatures in the bay’s upper 250 m have cooled to levels not seen since the mid 1980s. Observations and modelling trace the origins of this cooling to anomalous wintertime heat loss in the boundary current that circulates around the southern half of Greenland. Longer time series of ocean temperature, subglacial discharge and glacier variability strongly suggest that ocean-induced melting at the front has continued to influence glacier dynamics after the disintegration of its floating tongue in 2003. We conclude that projections of Jakobshavn’s future contribution to sea-level rise that are based on glacier geometry are insufficient, and that accounting for external forcing is indispensable.

Arctic ice is almost completely gone, not.

“Eleven years ago, I started analyzing the junk science behind the Arctic meltdown. This made the purveyors of the Arctic melting scam very angry.” click here

Arctic sea ice is stable, defying past doomsday predictions

“A look at the real observed data on polar sea ice shows that the situation has been surprisingly stable for more than one decade, now, despite the cult-like doomsday prophecies that much more ice would be gone by now.” click here

Arctic sea ice volume continues to grow

“Last year had the highest June Arctic sea ice volume since 2006, and this year is well ahead of last year.” click here

Arctic sea ice volume is increasing

“Arctic sea ice volume gain from January 1-23 has been second highest in the Danish Meteorological Institute record, just behind 2008.” click here  and here

Arctic sea ice volume increasing

“Ten years ago, America’s leading Arctic experts said the climate had passed the tipping point, and the Arctic could be ice-free between 2013 and 2018. The exact opposite has happened. Arctic sea ice volume is up 30% over the past ten years.” click here

Predictions of Arctic sea ice demise are not science-based

“There has been no trend in Arctic sea ice extent over the last twelve years. But climate scientists aren’t interested in facts.” click here
