Every day from December 2025 to February 2026, more than one in six people on the planet experienced temperatures with a strong climate change influence.

In 124 countries (home to nearly 2.5 billion people), the average person experienced at least 30 days with temperatures strongly influenced by climate change.

In 45 countries, all of the risky heat days in the past three months were driven by climate change.

Nearly 228 million people experienced 30 days or more of risky heat added by climate change during the last three months, and most of these people (81%) live in Africa.

In 54 U.S. cities, mostly in the western U.S., the average person experienced at least two weeks' worth of temperatures made at least two times more likely by climate change.
