A Little Good News
New analysis shows the Intergovernmental Panel on Climate Change’s once-feared RCP 8.5 “worst-case” emissions pathway is now unlikely thanks to recent climate policies and clean-technology deployment. Critics have mischaracterized this shift as an admission of error, but scientists say it reflects updated realities rather than a retreat from climate risks. Despite avoiding that extreme scenario, the revised worst-case trajectory remains severe, with higher risks of extreme-weather fatalities, mass extinctions and expanded vector-borne disease. Meanwhile, the formerly best-case pathway is slipping out of reach because global emissions are not falling fast enough to meet Paris targets.
