Scientists say Paris warming limit may be reached by 2029

Scientists say global warming could reach the Paris Agreement’s 1.5°C limit by 2029, much earlier than previously projected. The warning came as new reports at the COP31 climate conference found that government action has stalled and current policies leave the world far from meeting the agreement’s goals.

Copernicus said the projected date for crossing the threshold has moved forward from around 2045, when the Paris agreement was adopted. Climate Action Tracker estimates the world remains on course for nearly 5°F of warming by 2100; even full implementation of existing policies and promises would result in about 3.4°F. Analysts said new oil and gas projects and weakened climate policies are offsetting progress in renewable energy.
