Industry and the US federal government have long worked in tandem to sideline climate concerns and continue to promote Earth-warming fossil fuels. Now the US House Oversight and Reform Committee has summoned top executives from Exxon, Shell, BP and Chevron and two affiliated lobbying groups to testify in front of a committee hearing in October, as part of an ongoing investigation into the fossil fuel industry's promotion of climate disinformation.   Also, for the past 50 years, the US government has known about the problem of climate change but has continued to promote fossil fuel development and done little to avert a crisis. Longtime environmental leader Gus Speth joins us to discuss his new book “They Knew.”   And a recent study found that three-quarters of young people surveyed believe the future is frightening because of climate change. What young people are expressing about their eco-anxiety and how parents can safely talk to their kids about climate.   Join us on October 5 for our next Living on Earth Book Club event! “Guardians of the Trees” author Dr. Kinari Webb will join Steve Curwood and Bobby Bascomb to talk about healing the world’s rainforests and the communities who depend on them.
