What will be the trend in global atmospheric CO₂ concentration recorded by NASA's OCO-2/OCO-3 satellites in the first quarter of 2027 compared to the same period in 2026?
In October 2026, NASA updated the algorithms for the OCO-2 and OCO-3 satellites, which… 88 opinions, 82% Increase (above 1 ppm compared to Jan–Mar 2026)
- Increase (above 1 ppm compared to Jan–Mar 2026) — 82%
- Stabilization (variation within ±1 ppm) — 13%
- Reduction (below 1 ppm compared to Jan–Mar 2026) — 6%

Frequently asked questions about this event
How is this event resolved?
Resolvido com base nos dados oficiais de CO₂ divulgados pela NASA para os satélites OCO-2/OCO-3. Compara-se a média de concentração global de CO₂ de janeiro a março de 2027 com a média do mesmo período de 2026. Se a diferença for superior a +1 ppm, resolve 'Aumento'; se estiver entre -1 ppm e +1 ppm, resolve 'Estabilização'; se for inferior a -1 ppm, resolve 'Redução'.
How are points scored?
Points depend on the share of votes your side had when you gave your opinion. Being right earns 100 minus that share. Being wrong costs that share.
Right now Increase (above 1 ppm compared to Jan–Mar 2026) has 82% of the votes: an opinion on it that turns out right earns about 18 points, a wrong one costs about 82.
