## Key points

- The Paris pact aims to limit warming to 1.5C.
- A single hot year does not breach the 20-year threshold.
- Climate finance helps poorer nations respond to impacts.

## Summary

The 2015 Paris Agreement commits almost every country to cut greenhouse gas emissions and limit global warming, aiming to keep temperature rises well below 2C while pursuing a 1.5C limit. The goal matters because each increment of warming raises risks, and UN scientists say impacts at 2C or more would be substantially greater than at 1.5C.

Countries set their own emissions targets and are expected to strengthen them every five years; richer nations also provide climate finance to help poorer countries adapt and shift to cleaner energy. The 1.5C threshold refers to a 20-year average, so the fact that 2024 exceeded it on its own did not mean the target had been breached. The United States withdrew from the agreement in January 2026, while Nepal was approved for support from a loss-and-damage fund after deadly August 2026 floods.
