Antarctic Peninsula Cools, Ice Shelves Advance, Media Silent
Scientists are struggling to keep their stories straight regarding the anthropogenic CO2 impact on polar climates.
It is claimed that anthropogenic CO2 emissions from burning ‘fossil fuels’ are responsible for amplifying warming (“polar amplification“) and ice melt in polar climates, consistent with pronouncements pertaining to ‘anthropogenic global warming’.
However, Antarctica’s Larsen Ice Shelf station indicates a cooling trend, -1.1°C per decade, has been ongoing since the late 1990s (Bozkurt et al., 2020).

About 85 percent of the East Antarctic Peninsula ice sheet has sustained “uninterrupted advance” since 2003 (Christie et al., 2022).
East and West Antarctica have been significantly cooling since 1979. Overall cooling rates of -0.7°C and -0.42°C per decade from 1979 to 2018 indicate -2.8°C and -1.68°C total cooling, respectively, for the mainland continent during these decades (Zhu et al., 2021).
The Antarctic Peninsula only began significant cooling in the 1990s (Oliva et al., 2017), and thus the 21st-century cooling has not yet overtaken or reversed the overall trend since 1979.
Other scientists suggest rising CO2 leads to cooling, not warming, in Antarctica.
None of these trends or attributions are consistent with claims of ‘anthropogenic global warming’ or polar amplification as a consequence of rising CO2 emissions.

This is precisely what was being said in the 1970s, but wasn’t limited just to Antarctica. The scream was fossil fuels are causing the world to race towards an ice age, and then we had an uptick in solar activity – a hotter Sun – and after a few years of memory holing the “fossil fuels cause global cooling,” we had the switch to “fossil fuels cause global warming.” I’ll give the magic molecule of CO2 a lot of credit for being all things to all people, according to their need.
I had already developed a healthy distrust for “science” before “glowbull warming” reared its ugly head, and the mad dash to destroy everything that makes life interesting and worth while just made be even more distrustful. Then along came “covid” and destroyed what little faith I had left in “science.”
