Here is a news video from 7 March 2023, a record minimum, 52,000 sq miles less than the previous record. Certainly the oceans won't rise due to this ice melt, that wont happen until the glaciers and grounded ice sheets break up, but what it is doing is putting millions of tons of water into the atmosphere.

This added 'humidity' coupled with the higher temperatures is what is causing debilitating heatwaves across the world, and no doubt is what is responsible for the severity of some flood events in recent years. Much is made in the media about heat, but heat in itself isn't life threatening. I have worked in 45 deg-C temps, it's not fun but the evaporation of your sweat cools you. With high humidity that sweat can't evaporate, the air is saturated, your body overheats and the water stops weeping from your pores.

Why the media doesn't report this is a mystery because drinking loads of water in such conditions is the last thing you should be doing. Water is a heat sink, you full your gut with water you end up with a hot water bottle inside yourself. At the moment heat records are being broken in India and Venezuela among other places, and that's in the northern hemispheres early Spring! In fact they had a heat wave in India last month, Winter. Strange days ahead...

The positive thing about COVID, inflation worries and Ukraine is nobody is talking about global warming/heating, climate crisis, whatever. We're focused on REAL problems.

Are you sure? The West is absorbed in trying to figure out what a woman is. And absorbed in determining if 60 year old books are insulting to negros and must be rewritten immediately.

Yes, that's the facts. That and finding new ways to hide the fact the world's primary energy sources are getting harder and harder to get out of the ground. Mountain-top coal mining? Drilling a mile under the ocean? digging up tar to make oil? Fracking source rocks 10 million years before the oil would form naturally? I don't think the average person has a clue how much desperation is out there when it comes to maintaining the status Quo. In keeping the world's fleets of cars and trucks and trains and planes and ships and earthmovers and coal plants running.

Antarctic Sea Ice Is at Record Lows. Is It an Alarming Shift?
https://www.wired.com/story/antarctic-s ... ing-shift/

May 26, 2023
Since the late 1970s, satellites have been spying on Antarctica’s sea ice, watching the whiteness expand and contract with the seasons. But they’ve never seen the ice quite like it is right now. Or rather, the lack of it—levels have fallen to record lows.

“Every single day so far in 2023, we’ve observed sea ice that’s been below average,” says climate scientist Zachary Labe of Princeton University and the National Oceanic and Atmospheric Administration, who created the graph below. The dark-blue line shows the median area of sea ice between 1981 and 2010, a figure called the “extent” that researchers measure in millions of square kilometers. The red line below all the others is the extent so far in 2023.

“In fact,” Labe continues, “it broke its lowest point ever recorded in the satellite era. Which was striking, because last year, we also had broken that record.”...

I hadn't really looked at it but the above article is correct. 2023 set an knew all time low record for Antarctic sea ice at 1,788,000 km^2 which handily beat out 2022's new record of 1,976,000 km^2.

Image Shows Antarctic Ice After Hottest Month Ever: 'Uncharted Territory'

New satellite images show just how little sea ice is left in the Antarctic after the hottest month on record.

The continent is currently in the depths of winter, but the images posted by NASA Earth Observatory show a drastically lower amount of sea ice than is normal for this time of year.

Data collected by the National Snow and Ice Data Center (NSIDC), one of NASA's Distributed Active Archive Centers, on August 7 shows that Antarctica's sea ice averaged 5.2 million square miles in July, which is the lowest ever observed since records began in 1978.

This follows July 2023—the hottest month globally that has ever been recorded, according to the World Meteorological Organization. During this month, it was 0.72 C warmer than the 1991 to 2020 average for July.

"What we're seeing this year is uncharted territory in the satellite record," Walt Meier, a sea ice scientist at NSIDC, said in a statement to the NASA Earth Observatory.



This year, the sea ice is 579,000 square miles lower than the record low set in the same period in 2022.

Previous data released this year shows that the last couple of years have been unprecedented for the continent.

In July, data released on July 19 from the Climate Reanalyzer by the University of Maine's Climate Change Institute shows that there was almost 772,000 miles² less sea ice in Antarctica compared to the same point last year. Last year, there were about 9.4 million miles of sea ice cover on the continent.

Antarctica goes through seasonal ice trends. In normal years, the continent sees around 15 million square kilometers of ice accumulation before it melts, NASA reported. But in recent years the ice growth has been dramatically slowed.

A yellow ring around the map shows where the ice used to reach, in the years 1981 to 2010. During this time, the sea ice covered an area the size of Mexico, the NASA Observatory reported.

Antarctica has seen a sharp decline in its sea ice coverage since 2014.

Since then, several record lows have been recorded, including in 2017 as well as 2022 and 2023.

"Most of the months since 2016 have been well below average," Meier said in a statement.

Scientists are not sure what caused the sea ice extent to change so dramatically, but this could continue as the world continues to warm.

Climate change is believed to be the main driving force behind Antarctica's low ice coverage.

"Sea ice around the Antarctic has taken a nosedive in the last few years, plummeting faster than any other time since observations began," Ella Gilbert, a climate scientist and presenter previously told Newsweek. "It's still too early to say conclusively whether this is a blip in the record or part of an emerging trend, but we expect sea ice to decline in a warming Antarctic. Sea ice is sandwiched between a warming atmosphere and ocean, so is sensitive to changes from above and below, although it has previously proved difficult to predict because there are so many complex factors at play."

Antarctica's melting ice will have profound effects on the planet if this continues. It is contributing to global sea level increases, which is a major threat facing the world's cities. Scientists fear that if something to mitigate climate change is not done immediately, it could get out of hand.

Well that's not good news? Two record years back to back isn't supposed to happen. Perhaps next year will be back up, if it's not my sister better think of selling her house by the ocean. She's already concerned and watching events closely, as are many others no doubt. And I ask myself, what's all that low lying real estate worth when the levels begin to rise? Very little I assume.

"Ice sheets are contributing to sea level rise sooner, and more than anticipated," said Eric Rignot, a glaciologist at the University of California, Irvine, and NASA's Jet Propulsion Laboratory in Pasadena, California.

That's because people have never seen the collapse of a huge ice sheet and therefore don't have good models of the effects, Rignot said.

The chart one month later. Ice formation increased at a greater rate than previous years but has flattened off. It will be interesting to see if it climbs much higher from here.

Except for when it happened in the 1960’s, conveniently before the period mentioned in the article.

However, in August 1966 the maximum sea ice extent fell to 15.9x10 km ± 0.3x10 km . This is more than 1.5x10 km below the passive microwave record of 17.5x10 km set in September of 1986. This variation between 1964 and 1966 represents a change of maximum sea ice of over 3x10 km in just two years. These inter-annual variations while large, are small when compared to the Antarctic seasonal cycle.
