UN warns world likely to overshoot 1.5°C, sees possible path back

A group of UN-led assessments warn that the 1.5°C limit is increasingly likely to be breached in coming years, but still callable back down through a sustained overshoot-and-reduction pathway that combines rapid emission cuts with large-scale carbon removal. The consensus remains that while overshoot is not inevitable catastrophe, it will entail decades of heightened climate risks and requires urgent, bolder action across mitigation, adaptation, and governance to keep temperatures from rising further.
