The Truth about Antarctica’s Larsen C Ice Floe
The large Larsen C ice floe (size of Delaware) is stuck along the Antarctic Peninsula due to the Coriolis effect. Antarctic scientists from the British Antarctic Research group and the U.S. National Snow and Ice Data Center (NSIDC) aren’t impressed. It happens every one or two decades.
Quoting:
“The calving event has the appearance of being a completely normal break of the ice shelf,” Ted Scambos, lead scientist at the Colorado-based National Snow and Ice Data Center”.

The Larsen C ice floe has grounded out on the multiple seamount formations along the Antarctic Peninsula. It’s not going anywhere. It has merely expanded the sea ice surrounding Antarctica which is hemmed in by the powerful circumpolar winds. Roaring Forties, Furious Fifties, Screaming Sixties.
Actually, the glaciers of Antarctica form in a very different way than Arctic or mountain glaciers. Steam and melt water feed the glaciers from below. It is the steam from multiple subglacial volcanoes , rifts, and trenches. Antarctica is very seismically active.
Quoting from linked source:
“The flanks of Erebus are spiked with ice towers, hundreds of them, called fumaroles. Gas and heat seeping through the side of the volcano melt the snowpack above, carving out a cave. Steam escaping from the cave freezes as soon as it hits the air, building chimneys as high as 60 feet.

Recent research has identified approx. 138 subglacial volcanoes in West Antarctica alone.

The Bentley Sub-glacial Trench extends 2 to 2.5 kilometers below sea level. Researchers from Washington Univ. (St. Louis) describe the bottom of the Trench as a “magma blow torch”.
Actually, due to the non-stop, heavy, circumpolar winds, Antarctica is isolated from the moisture in the southern tropics and mid-latitudes.
The circumpolar winds are the polar vortex of the South Pole. Due to differing geography, the Northern Polar vortex wanders quite a bit and allows warm, moisture-laden air to drive out of the warm tropics up into the Arctic (2nd Law of Thermodynamics – heat flows from a warmer source to a colder destination).
Because Antarctica is so cold it is very dry. Very little snow falls in Antarctica but the heavy winds pack it into drifts which receive the volcanic steam from below.
Glacial movement is lubricated by melt water. Also, the volcanic steam penetrates the cracks and fissures of the glacier as well as build the afore-mentioned fumaroles.

When the glacier moves beyond the heat-affected zone, the water re-freezes and expands, pushing up ice ridges. The ice ridges and fumaroles are where the ice accumulates. It has been doing so at least for 10,000 years. This is known from ice cores showing thick layers of ice produced since end of the last major Ice Age.
The last major Ice Age ended approx. 11,700 years ago. During the Ice Ages, Herndon’s GeoReactor was operating at reduced heat output. As GeoReactor activity increased, there has been greater steam emissions from the Antarctic subglacial volcanoes.
The following linked article reveals the findings of New Zealand Antarctic researchers, regarding the freezing ice beneath the Ross Ice shelf.

The linked article from National Geographic has all the requisite weasel words because any information contrary to the established meme is ignored and suppressed by the hysterical media and prostitute pseudo-scientists looking to scare the government into more grant funding as well as the UN Intergovermental Panel on Climate Change looking to expand the reach and power of the United Nations.
Man-made Global Warming is the greatest scientific hoax ever visited on humanity.

Probably Richard, it would be better not to quote or even mention “The Guardian” as many actual scientists might stop reading the moment they notice the name. Further, this tends to imply that you’ve found some merit in their left-wing socialist anti-science publications. To my thinking, it might be better to go to the actual research quoted by The Guardian and quote the source directly.
FWIW,

P.S. Forgot to mention that your article was well-written and very information. Keep up the good work.
