New Reconstructions Show It Is Colder Now Than At Any Time In The Last 10,000 Years

Scientists continue to find regions of the world where modern “global” warming has not occurred.

Sea surface temperatures (SSTs) in the South Atlantic (south of South Africa) and Southern Ocean (New Zealand) are colder today than they have been at any time in the last 12,500 years (Shuttleworth et al., 2021).

SSTs were multiple degrees warmer about 4,000 to 5,000 years ago, when CO2 concentrations were lingering near 265 ppm.

At the opposite end of the world, scientists (Allan et al., 2021) have determined the “optimal thermal conditions” for southwestern Greenland were when summer sea surface temperatures averaged about 12°C from 9,000 to 5,500 years ago. This is substantially (6-7°C) warmer than modern summer temperatures (4.0-5.2°C) for this region.

    […] And why is it that this global warming doesn’t make it warmer? […]

    Global Warming does make it warmer, but not in the way you expect. But you are still doomed.

    When all this airy fuss is buried and done with, I feel it will confirm my experience over 85 years of life that people always worry about the wrong thing.

    I expect, if still around, to be at least a little surprised.

    It doesn’t matter what rational arguments you present to shoot down their nonsense, the warm-heads will always deny, spin, manufacture some pseudoscientific blather to keep their religion going.
