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.

and here's my chart for the 10-year moving averages. There might even be an acceleration in these data....

Here's their wild looking chart for June SSTs.
