Sea-ice levels in Antarctica at a 'mind-blowing' historic low

Source: Business Insider

Sep 17, 2023, 6:09 AM EDT


Sea-ice levels in Antarctica reached a record low in mid-September, satellite imagery from the National Snow and Ice Data Center shows. Sea ice, the water that freezes on the surface of the sea in the Arctic and Antarctic hemispheres, has been decreasing in both regions.

In Antarctica, sea ice levels reached record lows at least twice in 2023 after record minimums were detected in 2017 and 2022. "It's so far outside anything we've seen, it's almost mind-blowing," Walter Meier, senior research scientist at the National Snow and Ice Data Center, told the BBC.

An unstable Antarctica could have far-reaching consequences for Earth's climate, forcing global temperatures to rise with potentially devastating consequences for humanity, scientists warn. Understanding the extent of climate crisis in Antarctica has been challenging for scientists. The region is 1.5 times the size of the US, and there's a lack of historical information.

"When I started studying the Antarctic 30 years ago, we never thought extreme weather events could happen there," Prof Martin Siegert, a glaciologist at the University of Exeter, told the BBC. But scientists seem to be changing their mind.

50 years? 100? 10? Most other species will be gone long before then, so its not a world I would want to live in.

When we have an entire political party in the pockets ($$$) of the fossil fuel industry and their propaganda
networks spewing lies about climate change, how do you fight them? Seems our only solution is to vote as
many Rs out of office as we can.

100-year, 500-year, and 1000-year floods.







Lots of "signal" shooting up above the normal volatile background "noise".

about how a "new" sub-population of polar bears were found in southeastern Greenland - https://climate.nasa.gov/news/3196/subpopulation-of-greenland-polar-bears-found-by-nasa-funded-study/

They seemed to have been able to adapt... at least so far, but no one is sure for how long.

After all we could live even if all the ice in the world melted but it's going to be damn near impossible if we kill the plankton in our oceans as they produce most of our planets oxygen.

It says there has been a temp increase of "...3.2-degC (37.76-degF)...".

But, a temp change of 3.2-degC equals a temp change of 5.76-degF. If Antarctica's temperature increased by 37.76-degF since the 1950's, Florida would already be under water. Not that that's a bad thing...
