Will September 2021 average global temperature be the highest September temperature on record?
In Response to Trader Inquiry: At the time of this market’s inception, the record high for September was +0.95 °C above the 20th century average. This value will continue to be used as the benchmark for this market, i.e. if September 2021 reports a value of +0.95 °C or higher, the market will resolve to “Yes,” otherwise “No.” Retroactive modification of past values will have no bearing on this market’s resolution. This is a market on whether the average global land and ocean surface temperature for September 2021 will be the highest September temperature since global records began in 1880. The resolution source for this market will be the Global Climate Report for September 2021, published by NOAA's National Centers for Environmental Information (https://www.ncdc.noaa.gov/sotc/global/2021). This market will resolve to “Yes” if, for the month of September 2021 averaged as a whole, global land and ocean surface temperature anomaly, as measured by U.S. National Oceanic and Atmospheric Administration, will be equal to or greater than 0.95°C (1.71°F) above the 20th century average of 15.0°C (59.0°F), and “No” otherwise. Note that if this September ties for highest, it will result in the market resolving to "Yes." Past data for the month of September can be found here https://www.ncdc.noaa.gov/cag/global/time-series/globe/land_ocean/1/9/1880-2021. This market will resolve when data is first available for the month of September 2021.
