After the Montreal Protocol, Where Are We With UV Radiation and Climate Change?

An unprecedented international treaty significantly reduced emissions of ozone-depleting substances, but there's still questions to answer.


Ultraviolet radiation has a few upsides in small quantities, but too much can cause a slew of health effects from sunburns to skin aging to even skin and eye cancer. Luckily, due to an unprecedented international treaty called the Montreal Protocol, the issue is improving, but as climate change worsens, there are still some reasons to be concerned. Today, we discuss where we’re at now with UV, what issues we still need to think about, and where we might go from here. With special guest Dr. Cédric Fichot: Assistant Professor of Earth & Environment at Boston University.
