Scientists Revise Worst-Case Global Warming Scenario
Recent updates from climate researchers indicate a downward revision of the worst-case global warming scenario. Previously, the most severe projection, known as RCP 8.5, estimated a potential rise in global temperatures by 5°C (9°F) above preindustrial levels by the end of the century. However, due to advancements in renewable energy and shifts in global emissions trends, this scenario is now considered implausible. The revised worst-case projection suggests a temperature increase of 3.5°C (6.3°F), with a more likely range of 2.5°C to 3°C (4.5°F to 5.4°F). While this represents progress, scientists caution that significant climate impacts, such as extreme heat waves, wildfires, and sea level rise, remain inevitable. The findings were published in April 2026 by a global committee of climate experts.
