Michael Shellenberger returns to expose how progressive policies have caused the skyrocketing rates of addiction, overdoses, crime, and homelessness in San Francisco and other major cities. We also assess the current state of the climate debate as Europe and California face escalating energy crises thanks to unreliable renewables.
