'BradCast' 5/20/2020 (Guest: Climate scientist Dr. Michael Mann)

On today's 'BradCast':  Michigan is grappling with double disasters – 10,000 residents forced to evacuate due to two catastrophic dam failures amid the ongoing COVID-19 crisis. But President Trump chose to attack Michigan today with completely false claims about absentee voting, and threatened to cut off federal funding to the state for lawfully mailing absentee ballot applications to all registered voters this year.  Trump made no similar threats against states Republican Secretaries of States taking the same action this year to help keep their voters safe during the global pandemic. Trump also committed absentee voter fraud himself in Florida this spring. Oregon held its all vote-by-mail primary election on Tuesday, and Trump didn't criticize the Republican Secretary of State for mailing actual ballots to every single registered voter in the state. Coronavirus shutdowns have caused a stunning drop in air pollution, and now a new study finds the lockdowns also caused a record-breaking daily drop in dangerous greenhouse gas emissions of about 17% in April. While temporary, it is likely to result in as much as a 7% reduction overall in emissions in 2020 – the amount that climate scientists warn we must cut every year, year after year, to avert the worst impacts of man-made global warming. Climate scientist Dr. Michael Mann of Penn State University explains the new study, the latest climate-fueled crises in Michigan and Bangladesh, and how the shutdowns demonstrate how society can cut emissions to mitigate future climate crisis-fueled disasters -- but we may have to make some change at the ballot box first...
