Some of the most traumatic highlights in Earth’s history can be found in ancient tree rings. University of Arizona researcher Charlotte Pearson discusses how scientists have found evidence of solar flares that struck the planet thousands of years ago, and how solar weather can damage infrastructure on Earth today.

Charlotte Pearson spoke with Tim Swindle, professor emeritus of Planetary Science at the University of Arizona.
