We’re asked to believe this is just a blip in the relentless march of supposedly human-caused global warming, but let’s give it a few more years to see how things progress.

Antarctica’s frigid winter temperatures are in contrast to trends in the rest of the world, which overall recorded its fourth hottest summer, says LiveScience.

Between April and September, a research station sitting on a high plateau in Antarctica, registered an average temperature of minus 78 degrees Fahrenheit (minus 61 degrees Celsius).

That’s the coldest temperature recorded since record keeping began in 1957, and about 4.5 F (2.5 C) lower than the most recent 30-year average, according to The Washington Post.

The previous record for the coldest winter was minus 77 F (minus 60.6 C) in 1976, Stefano Di Battista, a journalist wrote on Twitter. The Post learned of this record through Battista, but then confirmed the information with Richard Cullather, a research scientist at NASA’s Global Modeling and Assimilation Office.

The frigid winter is likely caused by a strong polar vortex in the stratosphere, the second layer of the planet’s atmosphere from Earth’s surface, according to the Post. “Basically, the winds in the polar stratosphere have been stronger than normal, which is associated with shifting the jet stream toward the pole,” Amy Butler, an atmospheric scientist at NOAA, told the Post. “This keeps the cold air locked up over much of Antarctica.”

What’s more, a strong polar vortex also leads to more ozone depletion in the stratosphere, which strengthens the polar vortex even more, according to the Post. Ozone is a gas made up of three oxygen molecules that is found high in the atmosphere. Ozone protects Earth’s surface from harmful ultraviolet rays and depleting it can expand the ozone hole over Antarctica.

While Antarctica logged the coldest known average winter temperature, satellites have detected individual temperatures that are far lower; as low as minus 144 F (minus 98 C), according to the Post.

Thanks to the frigid temperatures, sea ice levels around Antarctica were at their fifth highest extent on record in August, the Post reported. But the ice melted rapidly over the next several weeks, and by the end of September sea ice had thinned to some of the lowest levels seen at that time of year.

Scientists told the Post that the climate in Antarctica is prone to rapid change and that a frigid winter doesn’t mitigate the seriousness of climate change.

    Inconvenient. Aren’t the poles meant to warm first according to AGW theory?
    And, we’ve recorded a current 40 year cooling trend at the South Pole? Hmmm.

  5. irritable bill says:

    A strong polar vortex? Bullshit, all Southern countries experienced waves of freezing weather throughout winter…and this is because of the chaotic meridianal polar vortex…the very same “flubby” vortex issue the warmists pretend shows freezing weather means global warming …these f***ers make it up as they go along as their fervent congregation have the memory of a goldfish. Everyone who reads knows we are in a Grand Solar Minimum and also know what that means which is why we can make correct predictions…and they cant.

  6. Phoenix44 says:

    The point isn’t what caused it to be cold but that if it’s below average there it will be above average somewhere else. When the media and Alarmists shriek about above average temperatures they should be looking at whether other areas have below average temperatures and so all we are seeing is a more uneven distribution.

    Twentieth century bipolar seesaw of the Arctic and Antarctic surface air temperatures
    Petr Chylek,Chris K. Folland,Glen Lesins,Manvendra K. Dubey,
    First published: 22 April 2010

    In this paper we show that the 20th century de-trended Arctic and Antarctic temperatures vary in anti-phase seesaw pattern – when the Arctic warms the Antarctica cools and visa versa. This is the first time that a bi-polar seesaw pattern has been identified in the 20th century Arctic and Antarctic temperature records.
    – – –
    This paper makes the usual noises about greenhouse gas theory but then puts a few spanners in the works e.g….

    The first problem is that the early 20th century (1910–1940) rate of the Arctic warming (0.63 K/decade) was at least as high as the 1980–2008 warming rate (0.60 K/decade), suggesting that natural climate variability can produce a warming similar to the present one.

    https://agupubs.onlinelibrary.wiley.com/doi/full/10.1029/2010GL042793

    We further suggest the ocean variability contributed at least as much to the recent Arctic warming as the increase of atmospheric concentration of greenhouse gases (GHGs).
    . . .
    The intense Arctic warming since the 1970s (Figure 1a) arises from an additive combination of the general global warming trend with the warming phase of the multidecadal climate oscillation, while in Antarctica the cooling phase of the multidecadal oscillation opposes the general warming trend leading to essentially no significant Antarctic temperature change since the 1970s (Figure 1b).

    Worth bearing in mind that this record is less than 3 hale cycles long but interestingly 2 hale cycles ago (1976) lies the previous record 🤔

    Whatever the cause it’s not melting away.

    Between April and September, a research station sitting on a high plateau in Antarctica, registered an average temperature of minus 78 degrees Fahrenheit (minus 61 degrees Celsius).

    That’s the coldest temperature recorded since record keeping began in 1957, and about 4.5 F (2.5 C) lower than the most recent 30-year average

    Circulatory Topology – review

    My estimate: 99.9% of those discussing climate — weather left, right, or whatever else — don’t even know about mode 1.

    Just imagine how wonderful the climate discussion could have been (and wasn’t).
