This story was previously discussed here at WUWT… But, why wasn’t this headline news in the Washington Post, New York Times, etc.? Yes… That was a rhetorical question.

Plain Language Summary
The lowest measured air temperature on Earth is −89.2 °C (−129 F) on 23 July 1983, observed at Vostok Station in Antarctica (Turner et al., 2009, https://doi.org/10.1029/2009JD012104). However, satellite data collected during the Antarctic polar night during 2004–2016 reveal a broad region of the high East Antarctic Plateau above Vostok that regularly reaches snow surface temperatures of −90 °C and below. These occur in shallow topographic depressions near the highest part of the ice sheet, at 3,800 to 4,050‐m elevation. Comparisons with nearby automated weather stations suggest that air temperatures during these events are near −94 ± 4 °C or about −138 F. Ultracold conditions (below −90 °C) occur more frequently when the Antarctic polar vortex is strong. This temperature appears to be about as low as it is possible to reach, even under clear skies and very dry conditions, because heat radiating from the cold clear air is nearly equal to the heat radiating from the bitterly cold snow surface.

How much colder could it have gotten at 280 ppmv CO2? Probably not any colder at all.

‘It’s Almost Like Another Planet’ – Coldest Temperature On Earth Recorded In Antarctica

ScienceAs summer starts heating up, scientists just published the coldest temperature ever recorded on Earth. During the long, dark Antarctica winter temperatures dropped low enough to resemble other planets.
The temperature they measured? A stunning negative 144 degrees Fahrenheit (-97.8 degrees Celsius). At that temperature, just a few breaths of air would induce hemorrhaging in your lungs and quickly lead to death.
The temperature was recorded using satellite measurements in the middle of Antarctica during the depths of winter where the sun never rises. These findings, recently published in the journal Geophysical Research Letters, are close to the theoretical coldest temperature Earth can get down to.

The Coldest Place on Earth Is Even Colder Than Scientists Thought
By Mindy Weisberger, Senior Writer | June 26, 2018
Scientists already knew that the lowest temperatures ever measured on Earth were on a frozen ice ridge in eastern Antarctica, near the South Pole. But they recently discovered that temperatures there can drop even lower than those previously measured.
In 2013, analysis of satellite data pinpointed scattered pockets of intensely cold air on the East Antarctic Plateau between Dome Argus and Dome Fuji — temperatures that dipped to a staggering minus 135 degrees Fahrenheit (minus 93 degrees Celsius).
However, new analysis of the same data suggests that under the right conditions, those temperatures can drop to nearly minus 148 degrees F (minus 100 degrees C), which is probably the coldest it can get on Earth, researchers reported in a new study.

Despite runaway tipping points of Gorebal Warming, pushing the Earth back to the Pliocene, Miocene, Paleocene-Eocene Thermal Maximum, Cretaceous, Venus… well-within the Holocene noise level. It still gets as cold as theoretically possible in Antarctica.
I think we found Al Gore’s secret lair.
”Coldest” temperature? I have never met one of these. Is it animal, vegetable or mineral? I have heard of people who have experienced highest temperatures, lowest temperatures and even average temperatures but never cold temperatures or even hot temperatures.

CO2 freezes at −78.5 °C (−109.3 °F). So it could be snowing frozen CO2.
Big margin for error until they get down to bedrock to date the asteroid strike but a kilometre of ice may have covered a dirty big asteroid hole in Greenland in the last 12000 years-

They’ve just got to settle some science first.
Here in the American SouthEast, we are having record cold too. It feels like it gets colder every winter lately, and I don’t think it’s just my age. Of course they tell me that is “climate change” too. I wonder sometimes if we are actually seeing the temporary warming that comes before a new Ice Age. Glaciers covered the American East coast during the last ice age.
Dont worry, when theres a kilometer of ice above us we will be 1002 metres away from the top of it………….
