2025 could be the second hottest year in Earth's history

Data from Europe's climate change monitoring agency shows that average global temperatures continue to approach the 1.5°C threshold, marking three consecutive years that the planet has heated beyond the safe level set by the Paris Agreement.

The Copernicus Climate Change Service (C3S) predicted on December 9 that 2025 could become the second hottest year in the planet's history, on par with 2023 and behind the record-breaking hot year 2024.

Data from Europe's climate change monitor shows that average global temperatures are approaching the threshold of exceeding 1.5°C above pre-industrial levels, a level considered "relatively safe" under the 2015 Paris Climate Agreement.

Specifically, the C3S monthly update report shows that in the first 11 months of this year, the average global temperature was 1.48°C higher than the pre-industrial period, equivalent to the level recorded in 2023.

Notably, last month was the third hottest November on record, with the global average temperature rising 1.54°C above pre-industrial times.

Samantha Burgess at the European Centre for Weather Forecasts said these milestones show that temperatures are rising rapidly.

This is the first time that the global average temperature for three consecutive years (2023 - 2025) is forecast to exceed 1.5°C compared to pre-industrial times and the only way to minimize future temperature increases is to rapidly cut greenhouse gas emissions.

In addition, C3S also warned that ocean surface temperatures remained unusually high in November. At latitudes from 60 degrees South to 60 degrees North, ocean surface temperatures reached 20.42°C - the fourth highest recorded in November in observation history.

Each year, C3S collects and analyzes data from satellites and land and ocean monitoring stations. The agency currently owns a data repository that has been built since 1940.
