Warming Accelerates: Study Warns 1.5°C Limit Could Be Breached by 2030

A Geophysical Research Letters study, with 98% confidence, finds global warming has accelerated since 2015, rising about 0.63°F per decade compared with 0.36°F per decade from 1970–2015. If this pace continues, the 1.5°C Paris limit could be breached before 2030, risking climate tipping points such as ocean circulation breakdown, permafrost thaw, and coral reef loss, and leading to more extreme weather; meeting zero CO2 emissions is needed to stop warming, but current politics may allow the pace to continue unless major polluters—especially the U.S.—act decisively.
