Cancel all the claims by climate activists that global warming is decimating Antarctica. A peer-reviewed study recently published in one of the most prominent science journals destroys one of the most frequently asserted claims by climate activists – that climate change is warming Antarctica and melting the Antarctic ice sheet. The recent study confirms Antarctica has not warmed in the past 70 years and Antarctic ice cover is expanding rather than shrinking.

Writing in the journal Nature, scientists at Columbia University and the University of Victoria, British Columbia report, “The Antarctic continent has not warmed in the last seven decades, despite a monotonic increase in the atmospheric concentration of greenhouse gases.”

The scientists also observe that over the past several decades, “Antarctic sea ice area has modestly expanded.”

The scientists report that the topography of Antarctica, and particularly the size and distribution of Antarctic mountain ranges, play a large role in Antarctica’s stable (actually modestly cooling) environment.

The scientists published the image below, which shows how temperatures have changed during the past 30 years, compared to temperatures recorded between 1950 and 1980. Clearly, the vast majority of Antarctica is cooling, with warming occurring over just a small portion of the continent that juts out into the Southern Ocean.

Forget the claims of a warming Antarctica and remember the science – Antarctica is cooling, not warming.

  1. You know what? Sea level IS rising. NOAA
    https://tidesandcurrents.noaa.gov/sltrends/slrmap.html
    says 1.7 mm/yr but elsewhere it they cough up different numbers.
    Colorado University’s Sea Level Research Group
    https://sealevel.colorado.edu/
    says 3.3 mm/yr and 0.097 mm/yr² acceleration but two years ago they said 0.084 mm/yr² acceleration. So go figure.

    But yes, sea level is rising at some rate and at some acceleration, my spread sheet says around 0.01 mm/yr², and the water has to be coming from somewhere. The best bet is the Arctic & Antarctic ice caps plus the receding alpine glaciers around the world. But regarding the ice caps, they can’t melt they’re below freezing nearly everywhere nearly all of the time. But they can and probably are calving more ice into the sea than falls as snow in the interior.

    Regarding “Global Warming” “Climate Change” “The Climate Crisis” or whatever it’s being called these days, it’s mostly a gross exaggeration, political and not science if it ever was. A simple bumper sticker:

    CO2 is NOT
    a Problem

    CO2 is probably on balance mostly beneficial NOAA
    https://www.nesdis.noaa.gov/content/noaa-satellite-data-used-study-finding-significant-greening-earths-vegetative-areas
    Tells us that increasing CO2 has caused increased greening which includes food production. But yes it should cause some warming. Raw physics says 1.2°C of warming per doubling of CO2. Whether it actually does that is up for grabs. Warming the oceans and causing sea level rise due to thermal expansion? Pull my other leg.

  3. Thank you for your study. We need to somehow push back against the “catastrophic climate change” dogma before the hysterics totally ruin our country to “fix” a non-problem.
