Monthly Atmospheric Carbon Dioxide in January 2027?
Chart
Outcomes
Rules
The National Oceanic and Atmospheric Administration (NOAA) publishes the deciding data in its monthly "Trends in Atmospheric Carbon Dioxide, Mauna Loa" report. The deciding value is the atmospheric carbon dioxide concentration at Mauna Loa for January 2027, in parts per million (ppm), and the outcome is Yes if it is greater than the value specified in the market question and No otherwise. The value becomes final when NOAA publishes that report, by 8:00 AM CT on the fifth day of the month after January 2027, and early resolution does not apply. If NOAA delays the report, resolution waits until it is published.
About
