Caltech Science Exchange: Can Climate Models Be More Precise?

0 Просмотры
To explore and predict how the climate will change, researchers create computer models of the real world.

Models agree that the climate is changing because of human activity and that the average global temperature and the sea level will continue to rise. They also agree that weather patterns will change. Some of their specific predictions differ, primarily because each model includes different ways to model uncertain factors such as clouds.

In this video, Caltech’s Tapio Schneider, Andrew Stuart, and Anna Jaruga talk about why increased precision is an urgent goal for climate models.

Schneider and Stuart are cofounders of the Climate Modeling Alliance (CliMA). Schneider is Caltech’s Theodore Y. Wu Professor of Environmental Science and Engineering. He is also a senior research scientist at the Jet Propulsion Laboratory (JPL), which Caltech manages on behalf of NASA. Stuart is Bren Professor of Computing and Mathematical Sciences. Jaruga is a Caltech research scientist focused on clouds.
