Overview
- The UNEP report released Wednesday, Sept. 2, 2026, finds global warming is likely to exceed the Paris 1.5°C goal within a few years and that even the most optimistic pathway reaches about 1.8°C.
- UN leaders warned this summer’s record heat, wildfires and floods show the stakes and urged that any overshoot be made as short and small as possible.
- UNEP recommends an 'overshoot, peak and reduction' pathway that requires immediate, sustained cuts to greenhouse gases plus rapid scaling of carbon dioxide removal and long‑term storage.
- Some climate scientists and activists praised the report’s realism but warned its framing could reduce political urgency and called for stronger, faster implementation of national plans.
- If governments follow the report’s pathway, the agency says the duration of the overshoot could be limited and a return below 1.5°C is possible, though it will demand major policy, finance and technology action that affects vulnerable communities like small island states.
