Greenland’s largest glacier (Jakobshavn) has quite abruptly thickened since 2016. The thickening has been so profound the ice elevations are nearly back to 2010-2011 levels. The nearby ocean has cooled ~1.5°C – a return to 1980s-era temperatures.
The world’s glaciers have not been following along with the CO2-driven catastrophic melting narrative.
In the Southern Hemisphere, an accumulating collection of (29) referenced studies (Lüning et al.,2019) indicate that not only has the Southern Ocean, Antarctic Peninsula, West Antarctica, and East Antarctica been cooling or not warming in recent decades, but many regional glaciers have begun advancing again.
Greenland’s ice sheet mass losses have significantly decelerated since 2013 – a reversal from the rapid retreat from the 1990s to 2012 driven by cloud forcing and the NAO (Ruan et al., 2019).
The 47 largest Greenland glaciers also experienced a “relatively stable” period of rather insignificant retreat from 2013 to 2018 (Andersen et al., 2019).
Only 21 of the 47 Greenland glaciers retreated in 2018, 12 advanced, and the other 14 showed no trends in either direction (Polar Portal, 2019).
Greenland’s largest glacier, Jakobshavn, earned headlines in 2019 for it’s surprising and non-predicted rapid thickening in recent years.
A new study (Joughin et al., 2020) finds that the Jakobshavn glacier thickening that began in 2016 has continued apace, and ice elevation has now nearly completely returned to 2010/2011 amplitudes.
The authors attribute much of the glacier advance to the rapid 1.5°C ocean cooling impacting the region in recent years.
Ocean temperatures have returned to 1980s-era levels.

Nature subbornly refuses to co-operate with alarmist predictions, and you can guarrantee no good news about nature or the climate will appear in the mainstream media.

“it’s a complete reversal in behavior and wasn’t predicted” said Dr. Anna Hogg.
Well, now that puts a big “F” on your CPOM model….. Right?

Can someone please send an email to this stupid glacier telling it that it has to shrink, no matter what?

Seems like all the extra co2 in the atmosphere has thrown the models out of whack. We should outlaw climate predicting and all predictions made up of garbage being put into a computer and somehow expecting real results coming out . I can’t believe the amount of money wasted on paying people to perform whitch craft to make predictions that have now been wrong about 95 percent of the time. These people should go find real work that might actually help our children instead of fear mongering.

When you check out DANISH METEOROLOGICAL INSTITUTE LATEST NORTHERN HEMISPHERE SNOW MASS TOTALS there appears to be a lot of non mountain snow in this Northern Hemisphere winter. Reference- electroverse.com

The jacobshavn Glacier is positioned above a very significant heat emitting fault. This is what has cuased its rapid retreat. You may want to review the following plaeclimatology.com website of December 29, 2014 article that provides evidence suppoting this contention.
“Greenland Ice Melt Geotehrmal, Not Man-Made ” http://www.plateclimatology.com/greenland-ice-melt-geothermal-not-man-made?rq=greenland%20 .
The reason the glacier is now enlarging is that the geothermal heat has turned off. This is common of geological heat flow features.
