Trader consensus clusters tightly around 1.15–1.24ºC for April 2026 global surface temperature anomaly above pre-industrial levels (1850–1900 baseline), driven by NOAA and IRI ensemble forecasts projecting La Niña persistence through early 2026 at 50–60% probability, potentially capping anomalies 0.1–0.15ºC below 2024 El Niño peaks. Differentiating the narrow bins are uncertainties in ENSO transition timing—delayed decay favors higher bins (>1.20ºC)—alongside steady GHG radiative forcing near 1.2ºC and low volcanic aerosol interference. Recent Copernicus observations confirm September 2024 cooling to 1.1ºC amid La Niña onset, but North Atlantic warmth and model spread (ECMWF vs. CFSv2) keep lower bins (<1.15ºC) viable at 41–43% odds.

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