The charts below are produced by Zach Lane, a NOAA scientist.

The first chart tells a completely different story to the media narrative of a melting Antarctic. As you can see, most of the sea ice is actually thicker than normal. This is clear evidence of the ice edge being pushed polewards, squeezed closer together if you like:

The second image shows that, although ice volume is much less than average, it is NOT the lowest on record. The record low appears to be from the 1980s, though it is not clear which year.

What is noticeable though is that, apart from this year, most of the low volume years are coloured blue (1980s and 90s), whilst the top years are all recent:

The final chart is most the revealing of all. We can clearly see that the lowest volumes were around 1980 and 1981; also the trend was steadily increasing till it hit a record high in 2014. This was followed by the drastic drop in 2016, when, according to NSIDC, the SAM flipped. Since 2016, little has changed in overall terms:

And  no JM Antarctica doesn't have two lane highways. ;D ;D ;D ;D ;D

Unavoidable future increase in West Antarctic ice-shelf melting over the twenty-first century

then from the text -

"Using a regional ocean model, we present a comprehensive suite of future projections of ice-shelf melting in the Amundsen Sea. We find that rapid ocean warming, at approximately triple the historical rate, is likely committed over the twenty-first century, with widespread increases in ice-shelf melting, including in regions crucial for ice-sheet stability."

So we get a model, model projections, "likely" and the output is "Unavoidable". ;D ;D ;D ;D ;D ;D

JM I don't dislike you, you are just too much fun to ignore. ;)

It would take millions of years for that thick Antarctic ice sheet to melt.   ::)

Elevation.
Antarctica is the highest continent on Earth:
average elevation is 8,200ft (2500m). The elevation at the South Pole is 9,300ft (2835m).
The Antarctic continent is a land mass covered with ice up to 13,000ft (4km) thick. With all islands and ice shelves, Antarctica is nearly 1½ times the size of the USA, twice the size of Australia, and 58 times the size of the UK. It covers 8,500,000 square miles (13,661,000 square kilometers).

Poor JM fixing his opinions to the mast of the models. ;D ;D ;D ;D ;D ;D ;D

You could have just posted your verbal diarrhoea here. ;)

And still rambling about "runaway global warming". ;D ;D ;D ;D

" Runaway greenhouse scenarios on Earth are highly speculative, says Kahn. “We know that we’re not anywhere near that,” he said. “You basically need CO2 levels of a couple thousand parts per million, of which we recently passed 400 parts per million, or a massive release of methane, and there’s really no evidence for that at this time.” "

Monk,
you're just back from your 8th ban.

Are you calling the moderator of this MRB an idiot?

"Antarctic ice shelves provide buttressing support to the ice sheet, stabilising the flow of grounded ice and its contribution to global sea levels. Over the past 50 years, satellite observations have shown ice shelves collapse, thin, and retreat; however, there are few measurements of the Antarctic-wide change in ice shelf area. Here, we use MODIS (Moderate Resolution Imaging Spectroradiometer) satellite data to measure the change in ice shelf calving front position and area on 34 ice shelves in Antarctica from 2009 to 2019. Over the last decade, a reduction in the area on the Antarctic Peninsula (6693 km2) and West Antarctica (5563 km2) has been outweighed by area growth in East Antarctica (3532 km2) and the large Ross and Ronne–Filchner ice shelves (14 028 km2). The largest retreat was observed on the Larsen C Ice Shelf, where 5917 km2 of ice was lost during an individual calving event in 2017, and the largest area increase was observed on Ronne Ice Shelf in East Antarctica, where a gradual advance over the past decade (535 km2 yr−1) led to a 5889 km2 area gain from 2009 to 2019. Overall, the Antarctic ice shelf area has grown by 5305 km2 since 2009, with 18 ice shelves retreating and 16 larger shelves growing in area. Our observations show that Antarctic ice shelves gained 661 Gt of ice mass over the past decade, whereas the steady-state approach would estimate substantial ice loss over the same period, demonstrating the importance of using time-variable calving flux observations to measure change."

Andreasen et al 2023

"Cosmogenic-nuclide concentrations in subglacial bedrock cores show that the West Antarctic Ice Sheet (WAIS) at a site between Thwaites and Pope glaciers was at least 35 m thinner than present in the past several thousand years and then subsequently thickened. This is important because of concern that present thinning and grounding line retreat at these and nearby glaciers in the Amundsen Sea Embayment may irreversibly lead to deglaciation of significant portions of the WAIS, with decimeter- to meter-scale sea level rise within decades to centuries. A past episode of ice sheet thinning that took place in a similar, although not identical, climate was not irreversible. We propose that the past thinning–thickening cycle was due to a glacioisostatic rebound feedback, similar to that invoked as a possible stabilizing mechanism for current grounding line retreat, in which isostatic uplift caused by Early Holocene thinning led to relative sea level fall favoring grounding line advance."

Quantifying Antarctic-Wide Ice-Shelf Surface Melt Volume Using Microwave and Firn Model Data: 1980 to 2021  Banwell et al

https://agupubs.onlinelibrary.wiley.com/doi/10.1029/2023GL102744


They found that the highest meltwater volumes were produced on the Peninsula, reaching a peak in the 1992/1993 and 1994/1995, and that SNOWPACK calculated “a small, but significant, decreasing trend in both annual melt days and meltwater production volume over the 41 years.”

This record-shattering event saw numerous monthly temperature records being broken including a new all-time temperature record of −9.4°C on 18 March at Concordia Station despite March typically being a transition month to the Antarctic coreless winter.

So we have a new time record of MINUS 9.4C. In a month of warm weather. I guess he wants to link it to AGW, as is his want. ;)
