Recent updates to UN climate scenarios show that the most extreme warming projection, RCP8.5, is now considered implausible. This shift is largely due to the rapid global adoption of solar, wind, and electric vehicles, which has slowed the growth of carbon emissions. While the worst-case scenario has been sidelined, scientists warn that significant climate risks remain. Even moderate warming pathways pose threats through extreme weather events and ecological tipping points, emphasizing the continued need for decarbonization.
