2025 is expected to rank among the top three warmest years ever recorded globally, trailing only 2024 and 2023. Scientists say the ongoing streak of record-breaking warmth is no coincidence, but a clear signal of a warming climate driven largely by human activity.
Global surface temperature data collected from weather observation stations, ocean buoys, and satellites show average temperatures continuing to rise well beyond the climatological norm.
This three-year stretch of record warmth has exceeded the threshold outlined in the 2015 Paris Agreement, a nearly 200-nation pact aimed at limiting long-term global temperature rise to 1.5°C.
Despite this year being primarily influenced by a La Niña pattern, a natural cooling of Pacific Ocean waters, surface temperatures have still reached near-record levels…
