2023-2025 Set to Exceed 1.5°C Average Temperature Threshold

According to Copernicus data, the average global temperature from 2023 to 2025 is projected to exceed the critical 1.5°C threshold for the first time. This alarming prediction underscores the accelerating pace of climate change.

Notably, global temperatures from January to November 2023 were on average 1.48°C higher than preindustrial levels, with November 2025 reporting temperatures 1.54°C above preindustrial levels. This trend continues as 2025 is currently tied with 2023 as the second warmest year on record, reflecting significant warming in regions like Northern Canada and the Arctic Ocean.

The data reveals that the three-year average for 2023 to 2025 is on track to exceed 1.5°C, highlighting the urgent need for rapid reductions in greenhouse gas emissions to mitigate future temperature rises.

According to Dr. Samantha Burgess of the Copernicus Climate Change Service, these milestones reflect the ongoing climate crisis and the consequences of unchecked carbon pollution, which have intensified extreme weather events globally, including devastating floods and cyclones in Southeast Asia.

The World Meteorological Organization has echoed these findings, stating that the period from 2015 to 2025 will likely be recorded as the warmest decade in history, emphasizing the failure to meet the goals of the Paris Agreement as emissions continue to rise despite advancements in renewable energy.
