Study Confirms Antarctica Hasn’t Warmed In Past 70 Years
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.
This 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.

Hi James,
“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.” This explanation does not clarify the asymmetry of the heating. You show a large portion of Antarctica that’s cooling 1-2 degrees, but a very local heating of the Weddell and Amundsen seas. Previous studies have mentioned the melting of the west Ross Ice Shelf and the Thwaites glacier from underneath indicating some localized heating of the oceans underneath them. The air temperature is likely derived from this ocean heating, a fact confirmed by air temperatures on the western side of the Antarctic Peninsula that are warmer than the eastern (also not in your data but https://coolantarctica.com/Antarctica%20fact%20file/antarctica%20environment/climate_weather.php). I have in several publications attributed this (asymmetric) ocean warming to geomagnetic induction heating of the Ross Gyre due to the South Pole movement.https://youtu.be/HWDeroVenJc and also https://principia-scientific.com/wp-content/uploads/2020/07/vogel-prom-paper.pdf

We need to distinguish between heat content and temperature. Nine tons of ice mixed with one ton of water will have the same temperature as one ton of ice mixed with nine of water. But a different heat content. Only when the ice disappears, as it’s doing now, can we see an increase in temperature. But the ice has been melting, and the heat content increasing, for tens of thousands of years, well before mankind burnt anything. And if the source of that heat is not us, what is it? And what could ever stop it?
