According to a new study, 36% of 1979-2017 Antarctic ice loss was from the Thwaites and Pine Island glaciers. Scientists believed this glacier melt was due to anthropogenic climate change “until recently”. Now they say the glacier mass losses are due to the thin underlying crust and anomalously high geothermal heat in this region.
We’ve recently learned that “profound” cooling has been occurring for East Antarctica since the 1970s, and cooling (-1.68°C since 1979) has also extended to West Antarctica.
Another new study indicates Antarctica contributed just 0.76 of a centimeter to sea level rise from 1992-2017, or 0.3 of a millimeter per year. Also, comparing 1997-2008 to 2009-2018, there has been a net advance in the ice extent for Antarctica during 2009-2018.
“Until recently, experts attributed these changes to climate change”
The profound ice loss from West Antarctica’s Thwaites Glacier has by itself been responsible for about four percent of the global sea level rise in recent decades.
Possibly due to allegiance to “consensus” statements about anthropogenic global warming, it was still common for scientists to believe this glacier melt was due to the “warming” in Western Antarctica (that, as noted above, curiously disguised itself as cooling).
But a new study and its AAAS/Science press release throw more cold water on the notion that humans are driving ice melt trends in Antarctica, as “there is a conspicuously large amount of heat from Earth’s interior beneath the ice” in the very locations where the ice melt is most pronounced.

“The direct transfer of heat can facilitate basal melting and control ice rheology and basal sliding“
While the Earth’s crust has an average thickness of about 40 km, in the region of the Thwaites, Pine Island, and Pope Glaciers, the anomalously thinner crust (10 to 18 km) more readily exposes the base of this regional ice to 580°C tectonic trenches.
This must make those fearing global warming ecstatically happy!
academia is hypocritical, illiterate of truth and the distortion of actual facts. the longer one spends in this cress pool of pseudo erudite environment the more compromised rational thought processes become. rational reasoning processes is inversely proportional to elitist tenure.
December 29, 2021 – ‘The Fuse Has Been Blown’ – New data suggests a massive collapse of the ice shelf in as little as five years. “We are dealing with an event that no human has ever witnessed,” says one scientist. “We have no analog for this”
(If the Thwaites Glacier goes, nobody is going to be arguing about the danger of climate change anymore. It’s holding back enough glacial ice to raise global ocean levels by 10 feet.)

The Rolling Stone Mag is passe, every day is dooms day for your climate change whores. You take your cues from a high school drop out that wears antifa t-shirts. If it drops I hope Al gore and Barry get er first with their beach house mega mansions.
Jumping off to an old thread cause you are losing debate on another you are very predictable brother.

““At the end of the last Ice Age, the air became warmer and carried more moisture across the continent, doubling the amount of snow dropped on the ice sheet,” Zwally said.” And what ended that Ice Age? Primative SUV’s? Private jets? Mammoth farts?
“December 29, 2021 – ‘The Fuse Has Been Blown’ – New data suggests a massive collapse of the ice shelf in as little as five years. ” When this fear mongering prediction goes the way of “all beaches will disappear by 2020”, will you finally shut up about this farce or will you simply find another prediction to cling to?
So what’s your preferred solution? What being proposed by anyone will move the temperature in the direction you believe needs to happen, by how many degrees in what timeframe and costing how much? Based on science what are those numbers?
