In the case of Antarctica, the climate models were dead wrong, according to a new study by Chinese scientists published in the journal Cryosphere. The study found that most climate models predicted Antarctic sea ice coverage would shrink as the world warmed and greenhouse gas levels increased.
The opposite happened. Most climate models analyzed in the study predicted Antarctica would shrink between 1979 and 2005, but instead south pole sea ice levels increased during that time. Going a step further, sea ice levels have only increased since 2006, hitting all-time highs for sea ice coverage in September of last year.
“For the Antarctic, the main problem of the [climate] models is their inability to reproduce the observed slight increase of sea ice extent,” researchers wrote in their study.
“Both satellite-observed Antarctic [sea ice extent] and [satellite measured] Antarctic [sea ice volume] show[s] increasing trends over the period of 1979–2005, but [climate models’] Antarctic [sea ice extent] and [sea ice volume] have decreasing trends,” researchers added. “Only eight models’ [sea ice extent] and eight models’ [sea ice volume] show increasing trends.” (Read more about the Antarctic Sea ice HERE)
