Climate scientists are clarifying the role of the RCP8.5 scenario, a high-emission projection once used to model worst-case global warming. While recently deemed implausible, experts explain that its decline is largely due to the rapid global adoption of solar, wind, and electric vehicles, which has slowed the growth of carbon emissions. The discussion highlights the difference between low-probability risk modeling and actual climate trends. Even as the most extreme scenarios become less likely, researchers warn that current warming levels still pose significant risks to glaciers and coral reefs.
