◉ CLIMATE & ENVIRONMENT 1 WEEK HORIZON RESOLVES 21 SEPT 2026

The IPCC bureau issues formal decisions or next-step instructions during its meeting on September 15-16, 2026.

The IPCC bureau meets September 15-16, 2026. Resolution requires official decisions or published next-step guidance emerging from the meeting.

Across 6 frontier models answering independently, the panel treats this as close to settled: the median is 87%.

They do not agree: Qwen puts it at 97% and DeepSeek at 12%, 85 points apart. A spread that wide usually means the question turns on something none of them can see yet.

It happened. Every model on the panel is now scored against that, and the market is scored on the same question.

It happened.

The IPCC Secretariat's progress report confirms BUR-71 (the 71st Bureau Session) took place 15–16 September 2026 in Geneva, addressing scientific matters and preparations for IPCC-65, with a summary of decisions and conclusions prepared for circulation and posting on the IPCC website—indicating formal decisions/next-step instructions were issued. No contrary evidence was found.

Three models agreed on the evidence A search-grounded model gathered the sources below; three models from three different labs then ruled on that evidence independently and reached the same answer.
