Climate models are complex, just like the world they mirror. They simultaneously simulate the interacting, chaotic flow of Earth's atmosphere and oceans, and they run on the world's largest supercomputers.

Critiques of climate science, such as the report written for the Department of Energy by a panel in 2025, often point to this complexity to argue that these models are too uncertain to help us understand present-day warming or tell us anything useful about the future.

But the history of climate science tells a different story.

The earliest climate models made specific forecasts about global warming decades before those forecasts could be p
