Summary

Dust isn’t just something that accumulates between our couch cushions. Dust is ALL OVER Earth—there are 20 trillion grams of it!—and it plays a critical role in weather events, climate change, and how we understand Earth. This week, Dr. Sarah Aarons joins Jonathan to discuss her research on mineral dust, and her research trips to Antarctica. Plus, Jonathan asks hard-hitting questions, like: Is household dust really just dead skin cells? Does flushing your toilet make an aerosol mess? And how do you stay caffeinated near the South Pole? Sarah Aarons was born and raised in Alaska. She is an Assistant Professor of Geosciences at Scripps Institution of Oceanography at UC San Diego.
