All IPCC AR6 regions are close to their 1.5 °C- and 2 °C-equivalent warming limits
All Intergovernmental Panel on Climate Change AR6 regions sit close to their 1.5°C- and 2°C-equivalent warming limits, according to recent studies. Scientific findings indicate that global warming is already near levels previously forecast for 2040. Furthermore, discussions at COP31 in Türkiye warn that 90% of 1.5°C global warming has already been realized. While some analyses suggest that 1.5 degrees of warming is already here for most regions, specific locales may already be living in a 1.5°C warmer world. These updates highlight an acceleration in regional temperature changes that outpaces earlier multi-decade projections.

IPCC AR6 Regions Near 1.5°C and 2°C Warming Limits
All Intergovernmental Panel on Climate Change AR6 regions sit close to their 1.5°C- and 2°C-equivalent warming limits, according to recent studies. Scientific findings indicate that global warming is already near levels previously forecast for 2040. And discussions at COP31 in Türkiye warn that 90% of 1.5°C global warming has already been realized. While some analyses suggest that 1.5 degrees of warming is already here for most regions, specific locales may already be living in a 1.5°C warmer world. These updates highlight an acceleration in regional temperature changes that outpaces earlier multi-decade projections.
Why it matters
The Intergovernmental Panel on Climate Change AR6 regional assessments provide baseline metrics for evaluating localized climate shifts. Understanding whether regions are nearing or exceeding these specific temperature thresholds allows researchers to gauge the pace of global heating relative to long-term forecasts. These developments shift the timeline of expected climate impacts forward, altering how governments prepare for extreme weather and environmental degradation.
What is confirmed
- All IPCC AR6 regions are close to their 1.5 °C- and 2 °C-equivalent warming limits.
- Global warming is near levels forecast for 2040 according to a UVic study.
- COP31 in Türkiye warns that 90% of 1.5°C global warming has already been realized.
Still unconfirmed
- Some regions may already be living in a 1.5°C warmer world.
- 1.5 degrees of warming is already here for most regions.
What to watch next
- Further regional temperature assessments from upcoming climate conferences
- Additional peer-reviewed studies examining the timeline for 2.0°C warming realization
