Episode 358 - Wildfires, climate change, smog and charcoal

December 23, 2019

As the climate changes, wildfires become more common and more dangerous. Smoke clouds from wildfires can linger for weeks, but what chemistry changes inside the smog? Aerosols amongst other particles lurk inside wildfire smoke. How do we study the changes in wildfire smoke; by flying planes through the plumes. How do wildfires impact the CO2 emissions of a region?  Can wildfires help store carbon through charcoal? What can charred biomass to do help capture carbon?
