2023 likely to exceed 1.5 degrees

 From a toot by Robert Rohde (of Berkeley Earth) 


The recent extreme conditions have led to another upward revision to our forecast for 2023.

In addition to 2023 almost certainly becoming the warmest directly measured year, we now estimate roughly even odds that 2023 will be at least 1.5 °C (2.7 °F) above the 1850-1900 baseline.

Potentially exceeding – at least temporarily – the Paris Agreement target of limiting long-term global warming to no more than 1.5 °C.

This current period of record warmth is driven by a combination of man-made & natural factors.

The long-term trend is driven primarily by man-made global warming due to the accumulation of greenhouse gases in the atmosphere.

On top of this we also see short-term swings due to natural variability, including that associated with the recent transition from La Niña to El Niño.
