Global Average Temperature Hits New Record

In early 2025, the World Meteorological Organization confirmed that 2024 exceeded 1.5°C above pre-industrial levels for a full calendar year, marking the first breach of the Paris Agreement's aspirational warming limit. The global average temperature continued near or above that 1.5°C threshold into 2025, outperforming #1's localized impact by demonstrating a systemic planetary trend. While a single year above 1.5°C doesn't permanently breach the goal, this data point spurred urgent calls for emergency decarbonization.
