"Confronting the Role of Non-CO2 Pollutants in Global Warming"

"Aggressively reducing emissions of non-CO2 climate drivers could forestall abrupt climate change for up to 40 years, according to a recent study in the Proceedings of the National Academy of Sciences. Without such efforts, even drastic cuts to CO2 emissions will fail to put the brakes on planetary warming soon enough to avoid climate tipping points, the authors warn."
