Rapid cooling in the North Atlantic has reversed regional sea level changes and has apparently spread to the Greenland ice sheet.

Despite stressing global sea level rise is worrisome and due to anthropogenic warming, Chafik et al. (2019) report a distinct cooling trend in the North Atlantic that coincides with a transition to falling regional sea levels since 2004.

Meanwhile, Ruan et al. (2019) attribute the rapid deceleration in Greenland ice sheet melt since 2013 to the -2.0°C North Atlantic cooling that apparently has begun affecting the Arctic.

A cooling trend in recent decades has also spread to West Antarctica, the Antarctic Peninsula, and East Antarctica (Lüning et al.,2019).

North America as a continent has been cooling since 1998 (Gan et al., 2019), with no significant net change since 1982.

The Southern Ocean – 14% of the Earth’s surface – has been been cooling since 1979 (Zhang et al., 2019).

Large regions of the Northern Hemisphere – especially in Asia – have been cooling since 1990 (Kretschmer et al., 2018).

Other than these regions, the entire globe has been warming…in line with what would be expected with global warming.
