A Paris Progress Report
In June 2017, President Trump announced his plan to withdraw the country from the 2015 Paris Climate Accord, claiming it disadvantaged the United States. The symbolism of the American government’s retreat overshadowed the reality that the U.S. business community has embraced a low-carbon future. “We committed under Paris to do nothing we weren’t gonna do anyway and that we aren’t doing anyway,” says former Sierra Club chairman Carl Pope. Many countries have also reaffirmed their commitments to the Paris agreement. But how much progress has really been made, both at home and abroad?
Guests:
Gil Duran, Former Spokesman for Gov. Jerry Brown and Sen. Dianne Feinstein

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. Disasters like Superstorm Sandy and Hurricane Irma 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.
Guests:
Jonathan Patz, Director, Global Health Institute
Su Rynard, Filmmaker, Mosquito
Chuck Yarling, Engineer, Triathlete
Jessica Wolff, U.S. Director of Climate and Health, Health Care Without Harm

Selling the Science of Climate Change
The scientific consensus is that human activity is cooking the planet and disrupting our economies. Yet many people still don’t believe that climate change will affect them personally, or they deny the urgency of the problem. Can better communication help sell the science of climate change? “Only the repetition of simple messages changes public opinion and affects the brain,” says David Fenton, a four-decade veteran of PR campaigns for the environment, public health and human rights. “If you are not using effective messages that you repeat, repeat, repeat and are simple, then you get nowhere.”

The Population Bomb, 50 Years Later: A Conversation with Paul Ehrlich
In 1968, the best-seller “The Population Bomb,” written by Paul and Anne Ehrlich (but credited solely to Paul) warned of the perils of overpopulation: mass starvation, societal upheaval, environmental deterioration. The book was criticized at the time for painting an overly dark picture of the future. But while not all of the Ehrlich’s dire predictions have come to pass, the world’s population has doubled since then, to over seven billion, straining the planet’s resources and heating up our climate. Can the earth continue to support an ever-increasing number of humans? On its 50th anniversary, we revisit “The Population Bomb” with Paul Ehrlich.
Guest:
Paul R. Ehrlich, President, Center for Conservation Biology, Bing Professor of Population Studies, Stanford University; co-author, “The Population Bomb” (Ballantine, 1968)

Geo-Engineering Climate Solutions
In an emergency, we’re told to “break the glass” and grab the fire extinguisher. If we’re in the midst of a climate emergency, is there a firehose we could spray into the sky to cool down our atmosphere? It may sound like science fiction, but some climatologists endorse research into such techniques known as geo-engineering. But could tinkering with the stratosphere in this way lead to a new ice age – or worse? What group of people could be trusted with such God-like powers? Join us for a discussion of the scientific, moral, economic and technological dimensions of geo-engineering.

Climate One at Duke University: How Climate Change Will Change the Way We Eat

Exposed: Dieselgate's Impact on the Auto Industry
Volkswagen’s brazen cheating on air pollution rules rocked an industry with a history of skulduggery. The scandal has now cost the company $30 billion plus jail time for one. Furthering chaos in the auto industry is a Trump administration looking to roll back emissions standards while California and 12 additional states, making up 36% of the auto market, threaten to maintain theirs.

Mindful Travel in the Age of Climate Change
We’ve all heard that hopping on a plane is one of the worst things we can do for the climate. So how do we justify the environmental costs of world travel? Whether we’re scaling Mount Everest or diving with sea turtles in the Galapagos Islands, it’s important to tread lightly – and respectfully – on every corner of our planet. And ideally, use the experience to make the world a better place. Three veterans of adventure and eco travel talk about doing just that. Join us for a conversation about traveling mindfully and responsibly.

Dark Money and The US Chemical Safety Board
In her book “Dark Money: the Hidden History Behind the Rise of the Radical Right,” New Yorker writer Jane Mayer exposes the powerful group of individuals who bankroll our political system. Mayer traces the billions of dollars spent by the Kochs, the Mercers, and other wealthy conservative activists to influence policies related to climate change, the economy and more. And as the Trump administration rolls back regulations, the head of the US Chemical Safety Board, Vanessa Sutherland, wonders how much these billionaires will succeed in weakening government oversight of their business.
