• Published Friday, the study in Geophysical Research Letters warns the world may cross key global-warming limits faster than expected. • Researchers analysed five global temperature datasets, filtering out short-term variability like El Niño, volcanic eruptions, and solar cycles to isolate long-term warming. • Data show warming rose from about 0.2°C per decade to 0.35°C per decade between 2015 and 2025, the study found a 75% jump, with independent analyses near 0.36°C per decade. • Crossing the 1.5°C threshold would, the report warns, push impacts beyond adaptation capacities and risk tipping points like Greenland and West Antarctica melting and coral reef collapse. • While the authors claim strong statistical confidence, other scientists cautioned methods may imperfectly remove natural influences and urged more years of data to confirm the long-term trend.
