Gregg Garfin is an associate professor in climate, natural resources and policy in the University of Arizona’s School of Natural Resources and the Environment. He joins us to tell us about the projections for a significantly warmer climate in the Southwestern United States in the next century. He also explains why a monsoon doesn’t necessarily have to do with precipitation, and how an especially strong El Niño weather system can actually affect the Earth’s rotation.
