Average global land & ocean surface temperature, measured by NOAA

Update 2025-04-06 (PST) (AI summary of creator comment): Official Resolution Source: The market will resolve based on NOAA's official numbers.
Fallback Option: If NOAA is disbanded or unable to provide its data, the resolution will be based on data from another credible agency or the global scientific consensus.
@KJW_01294 It is the resolution source, so will resolve to their official numbers.
If NOAA gets disbanded, then probably we will need to find another credible agency or resolve to global scientific consensus

The high January temperatures have increased the odds of 2025 being the warmest year on record from 6% at the start of the year to 30% after January. However, the declines in global temperatures we've seen in February to-date in reanalysis may temper this.
note that it's down further in reanalysis since this tweet/report https://climatereanalyzer.org/clim/t2_daily/?dm_id=world
(edit: went back up since then)
@StevenK note also that Berkeley Earth's estimate was the highest/most uncertain out of four at the start of the year https://www.theclimatebrink.com/p/january-sets-an-unexpected-temperature
@StevenK they're now at 38% https://berkeleyearth.org/february-2025-temperature-update/
I assume you mean "2025 will be the hottest year so far", as in, compared to the years prior?
