Earth just had its second-warmest April in temperature records that date back to the 1800s, trailing only last year, per the EU's Copernicus Climate Change Service.
Why it matters: These monthly analyses offer fresh signs of a warming planet from one of the major stewards of global climate data.
- With four months of data in, climate scientist Zeke Hausfather posted that 2025 is likely to be the world's second-warmest on record.
Driving the news: Last month was 1.51°C above the estimated 1850-1900 average that Copernicus uses to define the pre-industrial era, per the comprehensive ERA5 dataset they use.
- And it was the 21st month in the last 22 months with average air temperatures was more than 1.5°C — a key Paris Agreement benchmark — above that era.
The bottom line: "Continuous climate monitoring is an essential tool for understanding and responding to the ongoing changes of our climate system," said Samantha Burgess, a top Copernicus official, in a statement.
