‘It will never be forgiven’: UN climate chief warns world to act or face disaster

Latest #Climate data shows a podium finish for 2025

We are in the decade where the 1.5°C limit is likely to be exceeded, highlighting the accelerating pace of climate change

Average global temperature for 2023–2025 is likely to exceed 1.5°C, the first three-year average to do so 🌡️🌏🧪⚒️
Why did GHG emissions rise?

50% of the increase was from land-use change, primarily due to more fires during El Niño. We expect this to drop in 2025. LUC is also very uncertain.

All other main regions, except EU27, with rising emissions in 2024.

For so long, fossil fuel projects have said their contribution to climate change is "negligible".
Turns out that's wrong.
Our research in NPJ Climate Action proves it.
