The Global Monitoring Laboratory has measured carbon dioxide and other greenhouse gases for several decades at a globally distributed network of air sampling sites. Data are reported as a dry air mole fraction defined as the number of molecules of carbon dioxide divided by the number of all molecules in air, including CO2 itself, after water vapor has been removed. The mole fraction is expressed as parts per million (ppm).

Rules and timeline

Each outcome is its own contract. A Yes contract pays $1 if its outcome happens and $0 if not; a No contract pays the reverse. Because the contracts trade separately, their chances don't have to add up to 100%.
