Last week in San Francisco, scientists, thought leaders, politicians and celebrities all gathered for the Global Climate Action Summit. Mark Hertsgaard covered the summit for The Nation magazine and is here on Sea Change Radio to provide us with his insights and takeaways from the event. Hertsgaard explains the summit’s mission, discusses his interview with outgoing California Governor Jerry Brown, and unpacks why it is that some environmental activists decided to protest the summit.

There is a nearly constant scroll of bad news passing before our eyes, from rampant income inequality and raging wildfires to climate devastation and white nationalists in the Oval Office.

Corporate profits are up, so in the eyes of the average news consumer, the economy is “strong.” But what factors are we missing in this declaration of strength? This week on Sea Change Radio, we discuss the state of the financial services industry with Graham Sinclair, who has worked in the field for over a decade.

There is no silver bullet to solve the intractable problem of global warming. Nevertheless, there is a lot of vital and hopeful work being done to chip away at the mountain of problems human beings have wreaked on this planet. This week on Sea Change Radio, we look at two innovative ideas that are moving us in a hopeful direction. First, we speak to Ian Power, an assistant professor at Trent University in Ontario, Canada, who is working on a breakthrough in manufacturing a CO2-absorbing mineral called magnesite in a fraction of the time that it forms in nature.

As wildfires rage out of control for yet another summer and the Mueller investigation inches ahead at a seemingly glacial pace, there’s a lot to be down about when it comes to politics and the environment. But this week on Sea Change Radio, we speak to a journalist who’s trying to look at things through a more upbeat lens. By delving into things that should encourage us about our future on this planet, Geoff Dembicki offers plenty of reasons to keep fighting the good fight against climate change.
