I’ll be double-hosting radio programs today on KALW. First, will California’s iconic Joshua Tree vanish from its namesake national park by the end of this century? I’m guest hosting Your Call’s One Planet Series at 10am PT, and we’ll discuss how climate change and development pressures are endangering Joshua Trees and what the state is doing about it. Joining us will be:

• Brendan Cummings, conservation director of the Center for Biological Diversity and a Joshua tree resident
• Dr. Cameron Barrows, professor Emeritus and Research Ecologist at UC Riverside

Then later in the program we will talk about a campaign by Fossil Free Media targeting oil and gas companies for their role in fueling climate disasters. Jaime Henn will join us, the founder and director of Fossil Free Media, a nonprofit communications lab that supports the movement to break free from fossil fuels.

Then at 6pm PT I’m hosting State of the Bay. You’ll hear my interview with State Senator Scott Wiener, whose bill to decriminalize psychedelics, SB 58, just passed the State legislature last week and is now headed to the Governor’s desk. Will Governor Newsom sign it?

Then I’ll talk to Silicon Valley investor, activist, and tech executive Tom Kemp about his new book, Containing Big Tech: How to Protect Our Civil Rights, Economy and Democracy.

Finally, you’ll hear from one of the San Francisco Dolphin Club members who recently swam across the English Channel, at the age of 75.

Tune in at 91.7 FM in the San Francisco Bay Area or stream live at 10am PT for Your Call and then again at 6pm PT for State of the Bay. What comments or questions do you have for our guests? Call 866-798-TALK to join the conversation!
