This market will resolve based on the data for the Global Land-Ocean Temperature Index for March 2026 versus the data points available for all other Marches on record. Note: If March 2026 is tied for first, second, or third hottest with another year, it will qualify for the bracket it ties with. The primary resolution source for this market will be the figures found in the table titled "GLOBAL Land-Ocean Temperature Index in 0.01 degrees Celsius" under the column "Mar" (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 March 2026 is provided by NASA by April 30, 2026, 11:59 PM ET, a consensus of credible sources will be used to resolve this market.Preliminary data from Copernicus Climate Change Service and NOAA indicate March 2026 global surface air temperature ranked fourth or lower among historical Marches, with anomalies approximately 1.1–1.3°C above the 1991–2020 baseline—trailing record-setters from 2024 (strong El Niño) and 2025. La Niña conditions through early March suppressed global averages despite extreme regional heat, such as the record-shattering U.S. Southwest heatwave. Trader consensus at 98.5% for "4th or lower" reflects this observational evidence and skin-in-the-game alignment with model baselines. Final NOAA confirmation expected April 8 could refine rankings slightly via ocean data adjustments, but upward shifts to top-three would require unprecedented revisions amid cooling ENSO-neutral transition.
