✓ The market called it — resolved 1.30001 or above.

The global average temperature for August 2026 officially registered an increase above 1.30 degrees Celsius, according to the latest data. This outcome confirms a persistent warming trend observed in recent years. While specific details on the exact margin or the direct causes for this particular month's increase were not extensively detailed in available reports, the National Oceanic and Atmospheric Administration's (NOAA) National Centers for Environmental Information (NCEI) confirmed the global temperature and precipitation monitoring for the month. Throughout the period leading up to this confirmation, the prediction market had strongly favored this outcome, with the probability for an increase above 1.30 degrees Celsius closing at 99%, reflecting a clear expectation among participants.

What to watch

The continued exceedance of such temperature thresholds will likely intensify discussions around climate policy and mitigation efforts. Scientists and policymakers will be closely watching subsequent monthly reports to determine if this trend accelerates or stabilizes, informing future strategies to address global warming.
