AI Overview

While Antarctica may experience regional sea ice gains in certain areas, it is not accurate to say that the continent as a whole is gaining 180 billion tons of ice annually. In fact, studies indicate that Antarctica is losing ice mass, with some studies showing that 180 billion tons of ice are melting and entering the ocean each year. This melting ice contributes to sea level rise.

Here's a more detailed explanation:

Antarctica's Ice Sheet:
Antarctica is primarily covered by a massive ice sheet, which stores about 90% of the world's ice and 70% of its freshwater.

Melting Ice:
Studies have shown that the Antarctic ice sheet is losing ice mass, with some research indicating a significant increase in melting rates.

Sea Level Rise:
This melting ice, including the 180 billion tons mentioned, contributes to global sea level rise.

Sea Ice:
While Antarctic sea ice exhibits regional variability, with some areas showing increased ice extent and others showing declines, overall, Antarctic sea ice does not exhibit a significant overall trend compared to the Arctic, where sea ice is clearly declining.

Regional Variations:
Some regions, like the Ross Sea, have shown increases in sea ice extent, while others, particularly around the Antarctic Peninsula, have experienced declines.

It's amazing when science is used !

One thing global superpowers will not deny is the urgent need to realign the power dynamics of the Arctic as its ice melts, making viable a massive increase of shipping through its waters.

It's the core reason Trump went off his c~nt about Canada and Greenland... and the reason Canada is purchasing Australia's over-the-horizon surveillance system.

It no longer matters. ASI will be in charge.

Antarctic and Arctic ice area are both at 2nd lowest in recent records due to warming seas. Arctic volume is also near record low in recent times. https://nsidc.org/sea-ice-today/sea-ice-tools/charctic-interactive-sea-ice-graph

No. Overall Antarctica is gaining mass. East Antarctica alone was losing mass.

"However, a recent study led by Dr. Wang and Prof. Shen at Tongji University has found a surprising shift: between 2021 and 2023, the AIS experienced a record-breaking increase in overall mass."

...

"Notably, four major glaciers in the Wilkes Land–Queen Mary Land region of East Antarctica reversed their previous pattern of accelerated mass loss from 2011 to 2020 and instead showed significant mass gain during the 2021 to 2023 period."

AIS - Antarctic Ice Sheet. The whole lot combined

In the last year.

So much for global warming Grin

Wow.

It's almost as if you're proud of your ignorance.

"However, this isn't a sign that global warming and climate change have miraculously reversed. Picture a long ski slope with a small jump at the end. That's what a line through the Antarctic ice sheet data looks like when plotted on a graph. While there have been some recent ice gains, they don't even begin to make up for almost 20 years of losses."

"Climate change doesn't mean that everywhere on Earth will get hotter at the same rate, so a single region will never tell the whole story of our warming world. Historically, temperatures over much of Antarctica have remained relatively stable, particularly compared to the Arctic, which has cooked four times faster than the rest of the globe. Antarctica's sea ice has also been much more stable relative to the Arctic, but that's been changing in recent years."

A polar loop of warmer water is active while snow increases indicating more sea-evaporation.

From your link Lee....What the experts say!!!

Quote:

Enhanced mass loss of the Totten, Moscow, Denman, and Vincennes Bay glacier basins, East Antarctica

The four key glacier basins in WL-QML region, i.e., Totten, Moscow University, Denman, and Vincennes Bay, exhibited mass loss intensification with a rate of 47.64±8.14 Gt/yr during 2011-2020, compared to 2002-2010, with the loss area expanding inland. The researchers explained “this accelerated mass loss was primarily driven by two factors: surface mass reduction (contributing 72.53%) and increased ice discharge (27.47%).”

Notably, the complete disintegration of these four glaciers could potentially trigger a global mean sea level rise exceeding 7 meters. Their pronounced ablation patterns already constitute a critical climate warning signal, warranting greater scientific attention to their stability.

The Full Paragraph :

Previous studies have consistently shown a long-term trend of mass loss, particularly in West Antarctica and the Antarctic Peninsula, while glaciers in East Antarctica appeared relatively stable. However, a recent study led by Dr. Wang and Prof. Shen at Tongji University has found a surprising shift: between 2021 and 2023, the AIS experienced a record-breaking increase in overall mass.

And the SLR is still about 3mm per year. Potential? What is the time line on this "potential". At 3mm per year that would be 2100 years or thereabouts., Oh noes PANIC. Grin

Of course it's scientists.

You not a fan of data, science and scientists?

You'd rather get your "facts" from Sky "News"?

"An abrupt change in Antarctica has caused the continent to gain ice. But this increase, documented in NASA satellite data, is a temporary anomaly rather than an indication that global warming has reversed, scientists say."
