Sea Ice Levels in Antarctica at a Shocking Historic Low

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


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.

Someone needs to tell you it’s not 2015. You know, the year I gave you the NASA reports? But, hey….keep lying. It’s who you are. ::Shrug::

BTW….any progress on those D1 NCAA football league championships?

Well, this article isn't from some little business magazine. It's just a bunch of scientists that study Antarctica for their entire careers. It discusses how some studies, particularly the studies of the IPCC are flawed and rely on future predictions that don't always occur. I include a partial quote.

eos.org/science-updates/new-perspectives-on-the-enigma-of-expanding-antarctic-sea-ice

Sea ice covers the ocean surrounding Antarctica, forming a key component of the coupled ocean-atmosphere-cryosphere system in southern high latitudes that helps regulate climate, ocean circulation, and marine ecosystems. The extent of Antarctic sea ice varies greatly from year to year, but 40 years of satellite records show a long-term trend. Although some Antarctic regions have experienced reductions in sea ice extent, the overall trend since 1979 shows increased ice.

The increase in Antarctic sea ice extent stands in stark contrast to conditions in the Arctic, where sea ice extent has declined significantly—by about 2 million square kilometers, or about 20%, over the past 40 years. Much of the observed loss of Arctic sea ice, which is in general agreement with expectations from climate models, has been attributed to anthropogenic global warming.

The trend in Antarctic sea ice, meanwhile, has confounded scientists—most climate models indicate that Antarctic sea ice extent should have decreased over the past several decades. Here we discuss results from three recent independent studies that all applied a “nudging” technique to the same climate model to study the influences of different processes on Antarctic sea ice extent.

Where Models and Observations Differ

The state of sea ice is usually described in terms of its aerial extent, which has been measured since 1979 by satellite platforms that detect differences in microwave emissivity of sea ice versus open ocean. The inability of climate models to simulate satellite-observed Antarctic sea ice trends adds uncertainty to our projections of how this sea ice will change through the 21st century.

These model simulations, which are widely used to understand and predict climate change more broadly (e.g., for the Intergovernmental Panel on Climate Change (IPCC) Assessment Reports), are run using observed (for past time periods) or prescribed (for future time periods) conditions, called external forcings. These forcings include factors such as the concentrations and compositions of greenhouse gases and aerosols in the atmosphere. However, these models are also “free-running” throughout their simulations—that is, they do not assimilate (incorporate) any new weather information as the model is running.

Newsflash, O'Chicken.  I completely debunked your misleading Antarctic ice trope in 2015.

Then you had a hissy fit and put me on ignore.  Then you forgot what happened.

LOL...wonder if his info came from the same moron who can't tell you if your picnic is gonna get rained out on Saturday, but is telling you we'll all be dead in 10 years if you drive an SUV to the office today...

Earth lost 28 trillion tonnes of ice between 1994 and 2017, with melting grounded ice (ice sheets and glaciers) raising the global sea level by 34.6 ±3.1 mm.[3] The rate of ice loss has risen by 57% since the 1990s − from 0.8 to 1.2 trillion tonnes per year.[3]

Yeah, cuz Wikipedia is so accurate, reliable, scientifically factual and stuff.

If the earth wants to warm up as part of its natural cycle, there is nothing puny man do about it.

It's hilarious that loony lieberals worry about natural "global warming," but don't give a single shit about the destruction of America that they are causing.
When the U.S. no longer exists, who will give a damn that we are 1 degree warmer on average?

Priorities, priorities.

Notice all the insurance companies bailing out of regional markets? Notice how insurance cost have doubled in areas where companies still sell insurance?
That is the price of ignoring climate change as you and other redhats have chosen to do.
Get your wallet ready.

No one is ignoring the facts that  (1) the earth goes through its natural warming and cooling cycles, and (2) there is nothing that puny man can do about it.

How much is earthquake, mudslide, and wildfire insurance out there in Commiefornia?

stupid wolly is f-ing insane if he thinks ins cos are not writing policies because global change warming climate mfr'd crisis xyz. Or is it because of pronoun identity, lol.
