This market will resolve to "Yes" if the data for the Global Land-Ocean Temperature Index for 2023 shows an increase of 1.15°C or greater when it is released. Otherwise, this market will resolve to "No".

An anomaly of 1.15°C or greater for 2023 will be sufficient to resolve this market to "Yes" immediately once the data becomes available regardless of whether the figure for 2023 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 "2023" (https://data.giss.nasa.gov/gistemp/graphs/graph_data/Global_Mean_Estimates_based_on_Land_and_Ocean_Data/graph.txt).

This market will resolve to "Yes" if any storm makes landfall in the conterminous United States as a Category 4 hurricane, as reported in official National Hurricane Center advisories (https://www.nhc.noaa.gov/archive/2023/IDALIA.shtml?) between market creation and December 31, 2026, 11:59 PM ET. Otherwise, this market will resolve to “No”.

This market may resolve based on the initial advisory released by the NHC for whether any storm has made landfall in the conterminous United States at Category 4 strength, regardless of any later retraction or analysis that may contradict the initial qualifying announcement. However, subsequent corrections or updates will be considered if they indicate a qualifying incident.
