A new study (Kumar et al., 2021) reports the “overall SST trend in the Weddell Sea is negative” since 1979 and this has occurred in tandem with “the expansion of SIE [sea ice extent].” Another new study (King et al., 2021) reports the oldest temperature stations in Antarctica show a cooling/non-warming trend since 1956.
Antarctica and the Southern Ocean sea ice extent surrounding it continue to defy the government-endorsed modeling that says “polar amplification” should dramatically amplify the global warming signal due to rising greenhouse gases
