Antarctic Sea Ice Decline May Be Due To Natural Factors

By Paul Homewood

We are familiar with the large swings in sea ice extent from year to year around Antarctica.

As No Tricks Zone reveals, these changes defy the computer models, and are almost certainly due to natural factors:



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
