Scientists warn 1.5°C climate threshold could be reached by 2029

Source Summary

Scientists warn that the 1.5°C global warming threshold could arrive by 2029, five years earlier than previously projected. Climate action has stalled over the past five years while fossil fuel development continues to expand.

Why it matters

The accelerated timeline for reaching 1.5°C represents a critical narrowing of the window for limiting climate impacts, with direct consequences for global climate policy and adaptation planning.
