Preliminary ERA5 reanalysis data and regional observations point to a March 2026 global surface air temperature anomaly hovering near 1.27°C above the 1850-1900 pre-industrial baseline, fueling the razor-thin trader split between 1.25–1.29°C (46.6%) and >1.29°C (42.1%). A record-shattering mid-month heatwave across western North America—deemed virtually impossible without human-induced warming—elevated Northern Hemisphere land averages, while fading La Niña conditions transitioned to ENSO-neutral, stripping away prior cooling suppression seen in early 2026. Berkeley Earth and NOAA datasets for prior months averaged ~1.55°C, but final ocean adjustments and Arctic contributions introduce uncertainty. Copernicus' official bulletin, due early April, will clarify resolution amid inherent reanalysis variability.

An anomaly within a named bracket for March 2026 is necessary and sufficient to resolve this market immediately once the data becomes available, regardless of whether the figure for March 2026 is later revised.
The primary resolution source for this market will be the figure found in the table titled "GLOBAL Land-Ocean Temperature Index in 0.01 degrees Celsius" under the column "Mar" in the row "2026" (https://data.giss.nasa.gov/gistemp/tabledata_v4/GLB.Ts+dSST.txt).
If NASA’s “Global Temperature Index” is rendered permanently unavailable, other information from NASA may be used.
If no information for February 2026 is provided by NASA by May 1, 2026, 11:59 PM ET, this market will resolve to the lowest range bracket.
