Thinning and retreat of West Antarctic glacier began in 1940s

New research by an international team shows that the present thinning and retreat of Pine Island Glacier in West Antarctica is part of a climatically forced trend that was triggered in the 1940s.

The team — made up of scientists from Lawrence Livermore National Laboratory, the British Antarctic Survey, University of Copenhagen, University of Alaska, Naval Postgraduate School, NASA Goddard Space Flight Center, Lamont-Doherty Earth Observatory of Columbia University, University of Leipzig, University of Geneva and University of Cambridge — analyzed sediment cores recovered beneath the floating Pine Island Glacier ice shelf. The team concluded the date at which the grounding line retreated from a prominent seafloor ridge was in 1945 at the latest.

The team also found that final ungrounding of the ice shelf from the ridge occurred in 1970.

“Our results suggest that, even when climate forcing (such as El Niños, which create warmer water) weakened, ice-sheet retreat continued,” said James Smith of the British Antarctic Survey and lead author of an article appearing in the Nov. 23 issue of the journal, Nature.

The first part of this article is written so as to give the appearance that catastrophic anthropogenic global warming is causing this ice sheet to retreat, but if you read to the end you see,

“This finding provided the first hint that the recent retreat could be part of a longer-term process that started decades or even centuries before satellite observations became available,” Smith said.",

and

“Despite a return to pre-1940s climatic conditions in the ensuing decades, thinning and glacier retreat has not stopped and is unlikely to be reversible without a major change in marine or glaciological conditions,” Smith said. “A period of warming in the Antarctic shelf waters triggered a substantial change in the ice sheet, via the mechanism that we see today — that is, ocean-driven thinning and retreat of ice shelves leads to inland glacier acceleration and ice-sheet thinning.”

The article also explains "forcing" as used in the lingo of CAGW hucksters and describes it as ancient climate trends such as El Niños, while still veiling the whole thing as global warming without expressly coming forward to say so except through wording trickery and omission.

The Western peninsula is melting, so what. It’s a very small percentage of the whole of Antarctica, which ICESAT data show is NOT melting: interior “gains exceed losses” on the coasts.

Which also means:

All sea-level rise data prior to 2016 is WRONG.

wasn’t there just another post a few days ago about there being more ice than usual? I tried to look on FR for it. Maybe it was to do with Arctic instead?

Trump should make sure that if there is any federal funding of pro-climate-change research, that it is matched dollar for dollar on the anti-climate-change side.

FDR's fault.

Let science do it the way it was before politics became the driver. Theorize, publish the research, peer review, and then when accounting for peer review, all of it, just the facts.

I thought I remember a couple articles saying that there was a volcano right off that area that was erupting causing the ice melt.

Better yet, tell them all to go start a GoFundMe page and ask Jill Stein to kick some money in while she’s at it.

Hey, now, it was Herbert Hoover’s mess that FDR had to clean up.

So who is the LIAR? In a recent thread here it said there has been no change in Anarctic ice in 100 years. Who is lying???? Somebody is throwing FAKE NEWS around.

Hey let’s spread the blame around a bit and bring Hitler into the mix. Mussolini and Tojo if you want to do the whole axis.

The glaciations that occurred during this glacial period covered many areas, mainly in the Northern Hemisphere and to a lesser extent in the Southern Hemisphere. They have different names, historically developed and depending on their geographic distributions: Fraser (in the Pacific Cordillera of North America), Pinedale (in the Central Rocky Mountains), Wisconsinan or Wisconsin (in central North America), Devensian (in the British Isles), Midlandian (in Ireland), Würm (in the Alps), Mérida (in Venezuela), Weichselian or Vistulian (in Northern Europe and northern Central Europe), Valdai in Eastern Europe and Zyryanka in Siberia, Llanquihue in Chile, and Otira in New Zealand. The geochronological Late Pleistocene comprises the late glacial (Weichselian) and the immediately preceding penultimate interglacial (Eemian) preiond.
