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.

"context_description": "Trader consensus on Polymarket overwhelmingly favors March 2026 ranking 4th or lower among the hottest on record (100% implied probability), driven by NASA's Goddard Institute for Space Studies (GISS) Surface Temperature Analysis v4 release on April 9, 2026. The global land-ocean temperature index registered just +0.11°C above the 1951-1980 baseline—well below recent record Marches like 2024 (+1.39°C, 1st), 2023 (+1.23°C, 2nd), and 2019 (+1.17°C, 3rd)—placing it around 12th warmest. Despite the contiguous U.S. shattering its March heat record at +9.4°F above average per NOAA, offsetting cooler anomalies in the Arctic, Canada, Russia, and parts of Eurasia under ENSO-neutral conditions suppressed the global average. Final GISS quality controls are unlikely to alter the ranking significantly.",
