Overview
- Roughly 50,000 participants gathered as UN climate chief Simon Stiell urged delegates to “fight this climate crisis together,” setting a cooperative tone for the two-week summit.
- The United States is absent after President Donald Trump withdrew from the Paris Agreement and dismissed climate action, a gap that negotiators say complicates efforts to raise ambition.
- Brazil is foregrounding forests and finance, pitching a Tropical Forests Forever Facility and a broader funding push that includes proposals reaching into the trillion‑dollar scale.
- Negotiators say consensus on stronger fossil‑fuel language is unlikely, with oil producers resisting a phaseout and Brazil’s fossil ‘roadmap’ still lacking detail.
- A new UN analysis shows current pledges would cut emissions about 12% by 2035 from 2019 levels versus the roughly 60% scientists say is needed, reinforcing warnings of a likely 1.5°C overshoot.
