New Pandemic

2026年新流行病？

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). If NASA's "Global Temperature Index" is rendered permanently unavailable, other information from NASA may be used. If no information for 2026 is provided by NASA by March 1, 2027, 11:59 PM ET, this market will resolve based on a consensus of credible reporting.

Otherwise, this market will resolve to "No".

The resolution source for this market will be the CDC Measles (Rubeola) counter (see: https://www.cdc.gov/measles/data-research/index.html) at the resolution time. If the counter becomes unavailable, another credible source will be used.

Note: Only cases reported by the CDC Measles (Rubeola) counter will qualify, regardless of reports from U.S. State agencies or other sources.

This market will resolve based on the data for the Global Land-Ocean Temperature Index for any month of 2026 versus the data points available for all years for the relevant month on record. If any month of 2026 is the hottest of that month for any year in record, this market will resolve to "Yes". Otherwise, this market will resolve to "No".

Note: If any month of 2026 is tied for hottest with the same month of another year, this market will resolve to "Yes".

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" (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.

This market may resolve immediately upon the release of data for any month which qualifies towards a "Yes" resolution.

If no information for all months is provided by NASA by January 31, 2027, 11:59 PM ET, a consensus of credible sources will be used to resolve this market.

This market will resolve according to the number of tornadoes recorded in the United States in 2026, based on the monthly counts published on the National Centers for Environmental Information U.S. Tornadoes Time Series page (see: https://www.ncei.noaa.gov/access/monitoring/tornadoes/time-series).

Only tornadoes appearing in the final NCEI dataset for all months of 2026 will count.

As of market creation, the December report is not yet scheduled, however the release schedule can be found here: https://www.ncei.noaa.gov/access/monitoring/dyk/monthly-releases. The market will resolve based on the first relevant tornado count published on the NCEI tornado time-series page after this scheduled release time.

If the value published after this scheduled release time is labeled preliminary, it will still determine resolution, and the market will resolve independently of any subsequent revisions, corrections, or retroactive adjustments. 

The market will not resolve based on any preliminary values published before the scheduled release time.

If no data is published by the scheduled release time, or if the NCEI website is temporarily unavailable, this market will remain open until that data is made available. If the relevant data is not made available by the date of the next scheduled publication ET, this market will resolve based on available data for the most recent prior month. If the NCEI website becomes permanently unavailable, this market will resolve using another credible source.
