Unheralded Global Ocean 2000-Year Temperature Reconstruction Reveals Embarrassingly Small Modern Changes
By Kenneth Richard on 12. October 2020
It didn’t receive much a attention in 2015, but a comprehensive Nature journal study of 0-2000 A.D. global sea surface temperatures shows 1) climate changes occurred more than twice as fast during the Little Ice Age (LIA) than since 1800, 2) the entire first millennium was >1 standard deviation (s.d. unit) warmer than today, and 3) 1800-2000 ocean changes amounted to just 0.08 of a s.d. unit per century.

There are several reasons to question the presentation of data in McGregor et al., 2015. – a global-scale reconstruction of sea surface temperatures.
The myriad authors decided not to clearly depict actual temperature changes in their reconstruction, preferring instead to “reimagine†temperatures as standard deviation units.
