Topographic map of Greenland
We’re told ‘The North Atlantic region is awash with geothermal activity’. Any day now we should be hearing how a few extra molecules of (human-caused) CO2 make the Earth’s innards hotter than they used to be. Or maybe we won’t.

A team of researchers understands more about the melting of the Greenland ice sheet, says SciTech Daily.
They discovered a flow of hot rocks, known as a mantle plume, rising from the core-mantle boundary beneath central Greenland that melts the ice from below.
The results of their two-part study were published in the Journal of Geophysical Research.
“Knowledge about the Greenland plume will bolster our understanding of volcanic activities in these regions and the problematic issue of global sea-level rising caused by the melting of the Greenland ice sheet,” said Dr. Genti Toyokuni, co-author of the studies.
The North Atlantic region is awash with geothermal activity. Iceland and Jan Mayen contain active volcanoes with their own distinct mantle plumes, whilst Svalbard — a Norwegian archipelago in the Arctic Ocean — is a geothermal area. However, the origin of these activities and their interconnectedness has largely been unexplored.
The research team discovered that the Greenland plume rose from the core-mantle boundary to the mantle transition zone beneath Greenland.
The plume also has two branches in the lower mantle that feed into other plumes in the region, supplying heat to active regions in Iceland and Jan Mayen and the geothermal area in Svalbard.

“problematic issue of global sea-level rising”
14mm increase over the last 17 yrs is problematic?
Seems well within thermal expansion characteristic to me.
Lets see some rudimentary figures on how much Greenland ice there is compared to the total ocean volume.
Shock news: Heat makes ice melt…

Greenland ice is about a metre or so in sea level terms as there is a big lake in the middle even when it all melts. Also the next glaciation will arrive before it can all melt.
It’s about time that volcanic activity was brought onto agenda. Will knock the socks off the CO2 obsession if honestly researched. Fat chance these days with politics now firmly in the seat.
You just have to look at the Antarctic image and draw a circle centred on the South Pole to get the picture. At least the ice knows where it can lie undisturbed.

thanks oldbrew, ya beat me to it.
These CAGW nuts and rent seekers have deliberately left off so many natural sources of heating and cooling for the planet it is a crime. If we’d used the money to do real science on climate, sea level, etc. we’d have had some really nifty data to view by now. Instead we’ve got tortured data that is essentially not just meaningless, it is red herring material leading us way off the track.
Looks like the article escaped trivial proofreading – with topography inserted for tomography …. beyond that – interesting stuff. There have been some isolated hot spots in Artic sea seen by satellites which look likely volcanic – but there’s been no ground truthing as there’s simply nobody up there ….
I’m considering a major change of communication strategy now, but readers may recall that the ERSSTv3b2 data tampering was a major factor in the exponential explosion of my redlining cynicism.
Exploring 66 & 96 year spatiotemporal patterns (which are not patterns in a global surface average) is challenging enough without persistent data vandalism.
Even the most careful investigators are likely to conflate the signals in the North Atlantic.
The most serious damage to ERSSTv3b2 was in the Southern Ocean — right beside the area highlighted in OB’s graphic above. The data manipulation introduced a SHARP artificial discontinuity.
I’ve come to regard the climate campaign as a western military strategy. No one pushing so hard would be safe pushing so hard without solid military backing. I have concluded that there is ABSOLUTELY nothing we can SAFELY do to stop the campaign — because as they say, “they will make other trouble”.
Reblogged this on Climate Collections.
Here’s hoping one day climate “scientists” will figure it out.

Antarctica rocked by 30,000 tremors in three months, Chilean scientists say
By Reuters — December 17, 2020
The peninsula is one of the fastest-warming places on Earth and scientists closely monitor the changing climate’s impact on its icebergs and glaciers.
But climate scientist Raul Cordero of the University of Santiago said it was not yet clear how the tremors might be affecting the region’s ice.

RECORD COLD HITS THE RUSSIAN ARCTIC COAST
DECEMBER 29, 2020
In addition, the crippling cold has also complicated shipping traffic in the Russian Arctic as it has led to a “significant” and faster-than-expected refreezing of the far northern rivers, bays and oceans.
