Catalyst Podcast with Shayle Kann
The greenhouse gas you don’t hear enough about
Nitrous oxide, or N2O, is the third-largest source of greenhouse gas emissions behind carbon dioxide and methane. Also known as laughing gas, it’s long-lived like carbon dioxide and incredibly potent like methane. And it accounts for about 6% of global warming. So where does it come from? And what do we do about it? In this episode, Shayle talks to Eric Davidson, professor at the University of Maryland Center for Environmental Science and principal scientist at Spark Climate Solutions. Eric studies a surprising source of nitrous oxide: bacteria in the soil.
