Scientists Find Antarctica Is Rapidly Cooling And Any Ice Sheet Melt Is Not Due To CO2, But Natural

Iowa Climate Science Education

Natural variability rules in Antarctica. Scientists identify clouds, wind, and localized solar heating – not CO2 – as the factors driving ice melt. Rising CO2 leads to Antarctic cooling.

Antarctica rapidly cooling in recent decades

In a review of the scientific literature, Lüning et al. 2019 report Antarctica as a whole has undergone a cooling trend in recent decades.

The Antarctic Peninsula has cooled at a rate of -0.5°C per decade since the late 1990s.

West Antarctica as a whole has “slightly cooled” (or the warming has “plateaued”) over the past two decades.

East Antarctica “has not experienced any significant temperature change since the 1950s” with  ice sheet mass gains and cooling during the past 15 years.

Rising CO2 leads to Antarctic cooling

Antarctica contains about 90% of the world’s ice.

Because the continent averages -28.2°C in summer and -60°C in winter
