Guest: Dr. Michael Pritchard, Director of Climate Simulation Research

When we think about climate models, we often picture supercomputers humming away in government labs or university basements. But increasingly, some of the most powerful tools shaping the future of climate science are coming from an unexpected place — Silicon Valley. Today, we’re joined by Dr. Michael Pritchard, Director of Climate Simulation Research at NVIDIA. Yes, that NVIDIA — the company known for powering gaming, AI, and some of the world’s fastest computing systems. But behind the scenes, NVIDIA is helping drive a revolution in climate and Earth system modeling, using advanced GPUs and machine learning to build faster, higher-resolution simulations of our planet. In this episode, we’ll explore how artificial intelligence is reshaping climate science, what it takes to simulate Earth in unprecedented detail, and why the future of forecasting may depend as much on silicon as it does on physics.
