Executive Summary
New analyses say human-driven warming is speeding up, with 2024 the hottest year and 1.5C likely to be exceeded before 2030
- Global warming has accelerated since 2015 to about 0.35 C per decade
- 2024 was the warmest year on record and the first calendar year above 1.5 C
- Scientists say human fossil fuel emissions remain the main driver of recent warming
- Rising heat is linked to more extreme weather, drought, ice loss and sea level rise
- Compound drought and heat events have surged in many regions since the early 2000s
- Paris Agreement goals require steep emissions cuts and net zero around 2050
- Recent COP talks ended without new fossil fuel commitments
Quick Facts
- What: Global warming is accelerating and nearing 1.5 C
- Where: Across the planet with strongest impacts in vulnerable regions
- Why: Burning fossil fuels raises greenhouse gases and traps heat
- Who: Scientists UN agencies and governments worldwide
- When: Since 2015 with 2024 and 2025 setting records
