Artificial intelligence (AI) is playing an increasing role in research and innovation. Chris Fletcher and his team are studying how AI can be used to improve computer models that are used to make predictions of future weather and climate. Fletcher says that such models, known as Earth System Models (ESMs), represent our only viable tool for making projections about how Earth’s climate will respond to human-induced increases to greenhouse gas concentrations. Fletcher’s work uses AI to improve the computational efficiency and scientific accuracy of ESMs, which occupy some of the world’s largest supercomputers. Fletcher and his team are breaking down academic silos and finding ways to use the latest AI technology to tackle complexities in climate change research.
