‘A Significant And Robust Cooling Trend’ In The Southern Ocean From 1982–2020 Defies Climate Models

A new study reports there has been a -0.3°C cooling in the Southern Ocean since 1982 per multiple observational data sets. The authors detail the “failure of CMIP5 models in simulating the observed SST cooling in the Southern Ocean.”

The Southern Ocean is today about 1-2°C colder than it has been for nearly all of the last 10,000 years (Shuttleworth et al., 2021, Civel-Mazens et al., 2021, Ghadi et al., 2020).

A new study (Xu et al., 2022) suggests the Southern Ocean (50°S–70°S) has continued to cool for the last 40 years, with amplitudes ranging from -0.1°C to -0.3°C per decade in some regions.

Climate models are unable to simulate this cooling, as they are famously incapable of accurately depicting the role of cloud forcing in modulating sea surface temperature trends.

“SST in the Southern Ocean is considered as an important indicator of climate change. This study shows that the Southern Ocean (50°S–70°S) sea surface temperature has a significant and robust cooling trend during 1982–2020”

    For those who, like myself, were curious about the proxies used to determine SST, and how robust it might be, this seems like a good paper to shed some light on that.

    Pretty standard method, apparently.

      If it is in disagreement with the sacred climate models, then it just does not suit the narrative.

        How right you are, mate!

    What does this mean for the Short Term (Decades) and for the Long Term (Century’s)?!?
    And if SST is going DOWN and the Sun is taking a nap (Solar Minima) does this mean Earth is going into another ‘mini Ice Age’?

    Antarctica and the Southern Ocean are where glacial termination and inception begin. Warming prior to Holocene inception began 20,000 years ago around Antarctica in the Southern Ocean.



    This it is likely that the next glacial inception will also begin in the Southern Ocean around Antarctica.

    Everything Defies CIMP Climate Models except maybe the temperature in the Arctic.
    Climate change in Antarctica and surrounding seas are completely unlike the Arctic.

    Climate models predict what they are programmed to predict.
    They are programmed to make scary predictions.
    Because their owners are paid to make scary predictions.
    Not accurate predictions.
