2026 State of the Climate Report
A 2026 BioScience climate report finds record glacier loss, ocean heat, and CO2 above 428 ppm as warming accelerates.
The seventh annual planetary vital signs report, published in BioScience, finds several Earth-system indicators at record extremes. Atmospheric carbon dioxide exceeded 428 ppm in May, roughly 50% above pre-industrial levels, and the warming rate roughly doubled to about 0.36°C per decade since 2010. Fossil-fuel consumption still rose 0.9% in 2025, while renewables surpassed coal in global electricity generation.
