Will it Snow in Seattle this December?

This market will resolve to "Yes" if the data for the Global Land-Ocean Temperature Index for 2025 shows an increase greater than that of any previously recorded year when it is released. Otherwise, this market will resolve to "No".

An anomaly greater than that of any previously recorded year for 2025 is necessary and sufficient to resolve this market to "Yes" immediately once the data becomes available, regardless of whether the figure for 2024 and/or 2025 is later revised.

The primary resolution source for this market will be the figure found in the table titled "Land-Ocean Temperature Index (C)" under the column "No_Smoothing" in the row "2025" (https://data.giss.nasa.gov/gistemp/graphs/graph_data/Global_Mean_Estimates_based_on_Land_and_Ocean_Data/graph.txt). If NASA's "Global Temperature Index" is rendered permanently unavailable, other information from NASA may be used.

Will 2025 be the hottest year on record?

This market will resolve to "Yes" if the data for the Global Land-Ocean Temperature Index for 2025 shows the second greatest increase of any previously recorded year when it is released. Otherwise, this market will resolve to "No".

An anomaly which is the second greatest of any previously recorded year for 2025 is necessary and sufficient to resolve this market to "Yes" immediately once the data becomes available, regardless of whether the figure for 2024 and/or 2025 is later revised.

The primary resolution source for this market will be the figure found in the table titled "Land-Ocean Temperature Index (C)" under the column "No_Smoothing" in the row "2025" (https://data.giss.nasa.gov/gistemp/graphs/graph_data/Global_Mean_Estimates_based_on_Land_and_Ocean_Data/graph.txt).

If no information for 2025 is provided by NASA by March 1, 2026, 11:59 PM ET, this market will resolve based on a consensus of credible reporting.

Will 2025 be the second hottest year on record?

This market will resolve according to the numerical rank of how hot 2026 is when compared against all other years for which the Global Land-Ocean Temperature Index has data.

Years will be ranked in descending order, starting with the hottest as number 1, the second hottest as number 2, etc.

If 2026 ties with any other year, it will resolve according to the place the year it ties with occupies.

This market will resolve immediately once the specified data becomes available, regardless of whether the figure for the relevant years is later revised.

The primary resolution source for this market will be the figure found in the table titled "Land-Ocean Temperature Index (C)" under the column "No_Smoothing" in the row "2026" (https://data.giss.nasa.gov/gistemp/graphs/graph_data/Global_Mean_Estimates_based_on_Land_and_Ocean_Data/graph.txt).
