Global warming speeds up after 2015, raising risk of 1.5°C breach before 2030
New analysis from the Potsdam Institute finds that after removing natural variability (El Niño, volcanic activity, solar cycles), the rate of global warming has accelerated since around 2015, with recent decades warming ~0.35°C per decade—faster than the ~0.2°C per decade from 1970–2015—across five datasets. If this pace continues, the 1.5°C limit could be exceeded before 2030. The study focuses on the pace, not the causes, and underscores the need for rapid CO2 emission cuts.
