2023 is the hottest year on record.

2023 was remarkable for Antarctic sea ice: it reached record low extents for the corresponding time of the year in 8 months.

Provisional ERA5 global temperature for 17th November from @CopernicusECMWF was 1.17°C above 1991-2020 - the warmest on record.

Our best estimate is that this was the first day when global temperature was more than 2°C above 1850-1900 (or pre-industrial) levels, at 2.06°C.
