Defying climate models, the sea ice surrounding Antarctica steadily increased during the 37 years from 1979-2015.
Even after many decades of studying climate processes and a supposed “consensus” that hemispheric-scale sea ice should decline in a rising CO2 concentration world, climate models cannot simulate the causative mechanisms for sea ice variability.
“Over recent decades Antarctic sea-ice extent has increased, alongside widespread ice shelf thinning and freshening of waters along the Antarctic margin. In contrast, Earth system models generally simulate a decrease in sea ice.” – Ashley et al., 2021
“Antarctic sea ice extent (SIE) has slightly increased over the satellite observational period (1979 to the present) despite global warming. [F]ully coupled Earth system models run under historic and anthropogenic forcing generally fail to simulate positive SIE trends over this time period.” – Blanchard-Wrigglesworth et al., 2021
Not just around Antarctica, but the sea ice in the entire Southern Hemisphere steadily increased from 1979-2015, in concert with the trends (cooling) in Southern Ocean sea surface temperature (Comiso et al., 2017).
