This April was world’s second-hottest on record, EU scientists say
- According to the Copernicus Climate Change Service operated by the ECMWF, April 2025 ranked as the second warmest April worldwide since records began.
- This status resulted from a long sequence of months with global temperatures remaining more than 1.5C above pre-industrial levels, based on extensive climate monitoring data.
- The monthly average temperature was 1.51C above pre-industrial levels and 0.6C higher than the 1991-2020 April average, while Arctic sea ice extent reached its sixth lowest April level in 47 years.
- Samantha Burgess, climate strategic lead at the Centre, noted that April 2025 ranked as the second hottest April globally, extending the series of months with temperatures exceeding 1.5°C above pre-industrial levels, and emphasized the importance of ongoing climate observation to track and address these changes.
- The April temperature data imply persistent global warming, with the yearlong period from May 2024 to April 2025 averaging 1.58C above pre-industrial levels, signaling ongoing climate change impacts.
