Even Colder than Scientists Thought.

Even with CO2 levels exceeding 400ppm and left wing politicians frantic to restrict energy use and human freedom, the Antarctic region continues to show record low temperatures  as low as any possible even at 280 ppm CO2.  Interesting reading.   And commentary at WUWT.

An inconvenient truth.

Here is also a link to the primary report (which may have limited time free access.)

FTA:  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.
