Briefings

Research published in Nature Climate Change indicates that regions worldwide may already be experiencing warming levels equivalent to a 1.5°C or 2°C global average, with 90-94% of the 1.5°C warming and 65-76% of the 2°C warming already realized in 2025. This finding suggests that adaptation is necessary across all regions immediately, as observed conditions match projected future scenarios.

Key points

• Regions worldwide may have already experienced 90-94% of the warming expected at 1.5°C global average warming.
• Regions worldwide may have already experienced 65-76% of the warming expected at 2°C global average warming.

Context

Findings from Nature Climate Change suggest that regional warming in 2025 was statistically indistinguishable from levels expected in a 1.5°C warmer world, underlining the immediate need for adaptation across all regions.

Limitations

Evidence is limited to 2025 data; specific regional locations are not identified; uncertainty exists regarding exact statistical significance of the match between observed and projected warming levels.
