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.
