Hottest June Ever

Copernicus [the Copernicus Climate Change Service (C3S)] released their temperature anomalies for June, and found that the global average temperature for June set a record, among Junes. Their data starts in 1979. {no fair! that's the beginning of the satellite era! ...So be it. The results from UAH and RSS also start in 1979.} They choose a baseline of 1991-2020. They write

Globally, June 2023 was:
  • 0.53°C warmer than the 1991-2020 average for June
  • the warmest June in this data record
  • substantially warmer than the 0.37°C anomaly in June 2019, the second warmest June on record

That's quite a jump for a new record.

Here's their wild looking chart for June SSTs. 


which is the region of the ocean west of London/Pyrenees/western Africa and from the equator to Iceland. (Latitude lines on this map are 36° apart.)
