Summary/Abstract
In this report, the authors analyze the influence of climate change on global temperatures between December 2024-February 2025 using Climate Central’s Climate Shift Index (CSI). The underlying data is available for download in the report.
The report’s key findings include:
- “At least one in five people globally felt a strong climate change influence every day from December 2024 to February 2025.”
- “Nearly 394 million people experienced 30 or more days of risky heat added by climate change during the last three months. Most of these people (74%) live in Africa. Risky heat days are days with temperatures hotter than 90% of the temperatures recorded in a local area from 1991-2020. Heat-related health risks rise when temperatures climb above this local threshold.”
- “In half of the analyzed countries (110 out of 220), the average person experienced temperatures strongly influenced by climate change for at least one-third of the season (30 days or more).”
- “In 287 cities, the average person experienced temperatures with a strong influence of climate change one-third of the season (30 days or more).”
