Busy week! Finally, one of the 14 climate lawsuits against the fossil fuel industry will go to court, as Exxon faces trial this week. We talk to Umair Irfan of Vox about what's at stake with these litigation efforts, how it compares to the Big Tobacco in the 1990s, and what the 2020 Democratic candidates are saying about it.   Then, we are joined by Liz Perera, Sierra Club's Climate Policy Director, talks about why mayors around the country will be flying into Washington D.C., to advocate for a federal clean energy bill.  As always, follow us @climatepod on Twitter and email us at theclimatepod@gmail.com.
