Global temperatures breach 1.5C Paris threshold
The world has been getting very hot.
In 2023, 2024, and 2025, the global temperature went over the 1.5 degrees Celsius limit set by the Paris Climate Pact.
This is worrying because even without the extra heat from El Niño, and with the cooling effect of La Niña, the temperatures stayed high.
Scientists say this means we might be entering a time when the world is always close to this dangerous heat level.
But they also say it's not too late to do something about it.
Global temperatures exceeded the 1.5 degrees Celsius threshold set by the Paris Climate Pact in 2023, 2024, and 2025.
The EU's Copernicus programme and the World Meteorological Organisation (WMO) both reported this breach.
The decade ending in 2025 is likely to be the warmest since the 19th century.
The high temperatures in 2025 persisted despite the absence of El Niño and the presence of La Niña, which usually cools the planet.
Scientists warn that this could mark the start of a period where global temperatures are consistently close to 1.5 degrees Celsius.
