Sea Changes: Why Oceans Play a Bigger Role in Climate Change Than You Think
Global temperatures would be soaring even higher were it not for a powerful heat-trapping ally: oceans. From regulating the temperature of the planet to generating half of the oxygen we breathe, oceans are a vital part of sustaining life on Earth. Increasing their temperature as little as two degrees, however, has an opposite effect, threatening marine biodiversity and turbocharging dangerous hurricanes and typhoons. But there are bright prospects on the horizon for humans and oceans. Join us for a conversation exploring how oceans play a bigger role in climate than you may think.
Guests:
Sara Aminzadeh, Commissioner, California Coastal Commission

How Climate Broke California’s Biggest Utility
PG&E has had a bad few years. A series of record-breaking wildfires culminating with 2018’s devastating Camp Fire propelled the California utility giant into lawsuits, $30 billion in liabilities and, ultimately, bankruptcy. Under new state laws, regulated utilities will have a hard time avoiding blame in fires where their equipment is involved—so what’s ahead for PG&E’s peers and their shareholders when a deadly blaze could spell bankruptcy? What happens when the California dream of living near nature is in direct conflict with disruptive tragedies fueled by climate change?

Dian Grueneich, Former Commissioner, California Public Utilities Commission

REWIND: Oppressive Heat: Climate Change as a Civil Rights Issue
While the environmental movement is typically associated with upper-class white folk, it is also a civil rights issue. Communities of color often live closest to factories and refineries that spew toxic pollution. That’s one reason why polls show more African Americans and Latinos say climate is a serious concern than whites. So why do environmental movements lack diversity, and why has it been so difficult for nonprofits to reach communities of color?

Fighting Fossil Fuels All the Way to Prison
How far would you go to make your voice heard on climate change? College student Tim DeChristopher disrupted an auction for oil and gas leases - and landed in prison. Georgia Hirsty and other Greenpeace activists suspended themselves from a Portland bridge to protest an oil rig bound for the Arctic. Such extreme activism gets headlines, and sometimes results. But is radical civil disobedience the most effective weapon for change? Or is collaborating with corporations to encourage sustainable practices a better way to make a difference?

Climate One at Harvard With Obama’s Climate Team
With the Green New Deal in the national spotlight, a vigorous debate is happening: how ambitiously and broadly must the U.S. act on climate? Are issues like economic equity, job security and public health outside the frame of climate action — or fundamental to its success? Greg Dalton welcomes two key members of President Obama’s climate team: former White House Science Advisor John Holdren and former U.S. EPA Administrator Gina McCarthy, in a special program recorded at the Harvard T.H. Chan School of Public Health in Cambridge, Massachusetts.
John Holdren, Former Science Advisor to President Obama, Teresa and John Heinz Professor of Environmental Policy at Harvard Kennedy School of Government

The New Surf and Turf
Production of animal protein is producing vast amounts of climate-eating gases. But a new generation of companies are creating innovative food products that mimic meat and have much smaller environmental impacts. Some of this mock meat is derived from plants with ingredients designed to replicate the taste and pleasure of chomping into a beef hamburger. Others are growing meat cells that come from a laboratory and not a cow. Could these and other culinary innovations wean Americans away from their beloved hot dogs, hamburgers and tuna melts, reduce our impact on the planet, and help feed the world’s growing population?

Insane Mode: Tesla’s Wild Ride
Despite having the top-selling luxury car in 2018, and a loyal if not rabid customer base, Tesla has been facing major challenges. In August, maverick CEO Elon Musk was slapped with SEC charges over some rather misleading tweets. That move cost him and the company millions in fines and forced Musk to step down as chairman. Other skidmarks for Tesla include production delays, shareholder skittishness and some well-publicized workplace complaints. Host Greg Dalton invites three journalists and Tesla-watchers to assess the health of Tesla, its overall impact on the auto industry and its future as a leader in the green economy.
Guests:
Hamish McKenzie, Author, “Insane Mode: How Elon Musk's Tesla Sparked an Electric Revolution to End the Age of Oil” (Dutton, 2018)

Naturally Wired: Getting Outside in the Digital Age
What does it take to get people off their phones and into the outdoors? Research has shown the deleterious effects of electronics on weight, sleep, and cognitive development in children, who in 2018 spend four hours or more each day glued to screens. Other barriers like income and proximity to nature make access to the outdoors extremely challenging for some families. Meanwhile, doctors have started prescribing hikes over medications, and terms like “forest schools” and “unstructured playtime” are new buzzwords. So how do we encourage outdoor curiosity and conservation in a generation raised on screen time?
Guests:
Phil Ginsburg, General Manager, San Francisco Recreation and Parks
Rebecca Johnson, Co-Director, Citizen Science at the California Academy of Sciences
