Recent observational data from agencies like Copernicus, Berkeley Earth, and NOAA confirm sustained global surface temperatures well above 1.4°C above the 1850–1900 baseline through mid-2026, driven by the long-term anthropogenic trend plus a rapidly strengthening El Niño with Niño 3.4 sea-surface temperature anomalies forecast to reach ~2.9°C by late summer. July 2026 ranked as joint-second warmest on record, and daily August readings have already set new highs for the date, reinforcing trader consensus that the August monthly anomaly will exceed 1.29°C. Model ensembles show high confidence in widespread above-normal land and ocean temperatures through the season. Only an abrupt, unprecedented cooling event or major downward revision in final datasets could realistically shift the outcome below this threshold.

An anomaly within a named bracket for August 2026 is necessary and sufficient to resolve this market immediately once the data becomes available, regardless of whether the figure for August 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 "Aug" 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 August 2026 is provided by NASA by October 1, 2026, 11:59 PM ET, this market will resolve to the lowest range bracket.
