Global Average Temperature Hits New Record

The World Meteorological Organization confirmed in early 2025 that 2024 had surpassed 1.5 degrees Celsius above pre-industrial levels for a full calendar year for the first time, and 2025 continued near or above that threshold. The milestone represented the first breach of the Paris Agreement's aspirational warming limit. Scientists emphasized that a single year above 1.5 degrees C does not permanently breach the goal, but the trend intensified calls for emergency decarbonization.
