Can California Go Carbon Neutral?
Just ten years ago, an entire state running on 100% renewable electricity seemed fanciful. But this dreamy vision became reality when, with the backing of big utilities, California committed to 100% use of zero-carbon electricity by 2045. A statewide pledge to go carbon-neutral by 2045 raised the stakes even higher. So what will it take for California to achieve such a feat? Will Governor Gavin Newsom embrace climate initiatives started by former Governor Jerry Brown? Join us in a discussion of California’s surprise gambit to take the world’s fifth largest economy to net zero.

Katharine Hayhoe: Why We Need to Talk About Climate Change
Many of us find it daunting to talk with our neighbors, colleagues and family members about climate change. But climate scientist Katharine Hayhoe says that having those difficult conversations is the first step towards solving the problem. Hayhoe is known as a “rock star” in the climate world for her ability to talk to just about anyone about global warming. She is joined by Stanford atmospheric scientist Noah Diffenbaugh for a conversation about communicating climate change in transparent, engaging, and accessible ways.

How Some Countries Are Solving Climate Change
When it comes to cutting emissions, there are many paths to success. Sweden, France, South Korea, and Ontario have all taken steps to replace fossil fuels with nuclear, hydro and renewable energy, while China is expanding electric car and battery production. But the absence of U.S. climate leadership is causing heads of state to ease off their goals, and violent protests in France against higher diesel taxes are casting a shadow over efforts to combat climate change. Join us for a discussion about who’s moving ahead and who’s moving backward in the transition to a clean energy economy.

Cool Clean Tech
Over a century ago, the industrial revolution brought wealth and opportunity to a generation of American innovators. It also brought us dirty coal power and a sky clogged with carbon emissions. The good news? There’s a new generation of entrepreneurs eager to make their fortune by fighting global warming. Creative start-ups are coming up with fresh, climate-friendly ideas for getting around town, powering your cell phones, and even eating breakfast. And there are a growing number of forward-thinking venture capitalist firms eager to seek out and nurture those innovative thinkers

REWIND: We're Doomed. Now What?
Can changing our consciousness hold off the climate apocalypse? When we think about the enormity of climate change and what it’s doing to our planet, it’s easy to get overwhelmed, even shut down, by despair. But is despair such a bad place to be? Or could it be the one thing that finally spurs us to action? A conversation about climate change, spirituality and the human condition in unsettling times.Guests:Roy Scranton, Author, "We're Doomed.

The Hidden Health Hazards of Climate Change
Climate change isn’t just an environmental problem – it’s also a health hazard. Air pollution and
changing weather patterns give rise to heat-related illnesses, asthma and allergic disorders.
Hurricanes and other disasters leave hospitals scrambling to save patients without power and
resources. According to the Centers for Disease Control, insect-borne diseases have tripled in
the United States in recent years – and warmer weather is largely to blame. Jonathan Patz, of
the Global Health Institute calls climate change “one of the most important public health
challenges of our times. Learn more about your ad choices. Visit megaphone.fm/adchoices

The Paris Agreement at Three: Floundering or Flourishing?
In its infancy, the Paris Agreement carried the promise of a truly global climate solution. Supporters still say the Agreement is the first step in setting the global economy toward a sustainable future, but U.N. reports now say current commitments are only a fraction as strong as they need to be, and critics say it's dangerously delusional to think the pact is ambitious enough to avoid catastrophic climate change. Katharine Mach, Senior Research Scientist at Stanford University, and Trevor Houser, Partner at the Rhodium Group, join host Greg Dalton for a Paris checkup, three years on.

Going Carbon Negative
The math is clear: lowering greenhouse gas emissions is not enough to keep the earth below 1.5 degrees Celsius of post-industrial warming. The latest science states that actively removing carbon from the atmosphere — storing it in rocks, soil, trees, and even turning it into products like concrete — is critical to restore the carbon and energy balance. To keep our planet from dangerous levels of warming, we’ll need to go carbon negative. Which natural and technological approaches are the most promising? Three experts and host Greg Dalton discuss the necessary negatives for a stable climate.

The Big Climate Stories of 2018
We’re making a list (and checking it twice) of 2018’s biggest climate stories, with the help of Vox reporter David Roberts. Roberts notes that while President Trump’s continued rollbacks of environmental protections made the news, the Green New Deal and ongoing decline in costs of clean energy technologies are the year’s big stories. For other parts of the country, wildfires and other extreme weather events made the biggest headlines. Greg Dalton talks to some of California’s leading wildfire experts about how to adapt to the “new abnormal” of more intense and more frequent wildfires.
Guests (in order of appearance):
David Roberts, Staff Writer, Vox
J. Keith Gilles, Chair, California Board of Forestry and Fire Protection; Professor of Forest Economics, UC Berkeley
Maggi Kelly Professor and Cooperative Extension Specialist in the Environmental Science, Policy and Management Department, UC Berkeley

Mind Over Chatter: Exploring Climate Psychology
We all know about the environmental and physical effects of climate change. But what about its impact on our mental health? Therapists report that their patients are exhibiting symptoms of what they call “climate anxiety” – loss of sleep, changes in appetite, feelings of grief, anger and hopelessness. How do we maintain our optimism in the face of a global existential crisis? And how do we talk with others about our fears without turning them off – or freaking them out? Three climate psychologists discuss how to cope with mounting anxiety brought on by climate change.
