A carbon offset is a credit – a way to offset a unit of pollution created in one place by, say, planting a tree, or otherwise sequestering carbon, somewhere else. But in the race to bring carbon emissions to zero, are offsets a legitimate tool, or a delusion that allows heavy emitters a way out of taking real action? “I just need to recruit everybody to make sure the forests remain forests and the farmlands have as many trees as possible,” says Pauline Kalunda, Executive Director of Ecotrust Uga...
Aug 30, 2019•52 min•Transcript available on Metacast Would you vote for the candidate who says he’ll declare climate change a national emergency on Day One of his presidency? Businessman and activist Tom Steyer says his willingness to use emergency powers to deal with the climate crisis sets him apart from the crowded field of Democratic candidates. “You have to start on day one, urgently – it's an emergency, treat it like an emergency,” Steyer urges. “I would give the Congress a 100 days … to pass something like the Green New Deal, but they've ha...
Aug 23, 2019•52 min•Transcript available on Metacast What’s new in renewable energy? In April, 23 percent of America’s electricity came from renewables, surpassing coal for the first time. Ten states, and Puerto Rico and Washington DC, have policies in place to run on 100 percent clean power in coming decades. Achieving that presents a host of challenges, from updating an aging electricity grid to financing energy innovation to figuring out how to transport and store the renewable power. Fortunately, says author Russell Gold, we have the talent to...
Aug 16, 2019•52 min•Transcript available on Metacast The California dream, with its promise of never-ending sunshine, fertile soil and rivers running with gold, has been beckoning people west for over two hundred years. But making that dream come true for an ever-increasing population has taken its toll on the landscape. Is the California dream coming to an end? When its current water system was built in the 1960s and ‘70s, California’s population was about half of the forty million who live there today. And every one of its citizens needs water t...
Aug 09, 2019•52 min•Transcript available on Metacast When it comes to solving climate change, where do we start? The organization Project Drawdown has published a list of top solutions for climate change – impactful actions already in existence that not only reduce carbon emissions, but also improve lives, create jobs and generate community resilience. “If you’re thinking about how to solve climate change here's where you start,” says Jonathan Foley, Project Drawdown’s executive director. “Electricity is about a quarter of the problem. Food, agric...
Aug 02, 2019•52 min•Transcript available on Metacast The climate conversation in Washington has changed enough that Democrats and Republicans are talking climate deals. A lot of that change can be attributed to the Green New Deal, a Democratic resolution introduced by Rep. Alexandria Ocasio-Cortez and Sen. Ed Markey. “What we're doing with the Green New Deal is we’re putting together an army that won't just be a resolution, it's a revolution,” boasts Markey, who has served over 40 years in Congress and co-authored the last big legislative push for...
Jul 26, 2019•52 min•Transcript available on Metacast How will we feed a planet that’s hotter, drier, and more crowded than ever? Much of it starts with innovators who are trying to re-invent the global food system to be more productive and nutritious. Vanderbilt University Journalism professor Amanda Little chronicles some of these efforts in her new book, The Fate of Food: What We'll Eat in a Bigger, Hotter, Smarter World. “We see disruption in the auto industry, we see disruption in tobacco – disruption is coming in the meat industry,” says Litt...
Jul 19, 2019•53 min•Transcript available on Metacast When Ridley Scott envisioned the dystopian Los Angeles of 2019 in “Blade Runner,” he probably didn’t think about how much energy would be needed to run those flying cars and sky-high animated billboards. Or what all those carbon emissions would be doing to the climate. We’re now living in the world of 2019. Flying cars are still in the future. But with over half of the global population living in urban centers, and another 2.5 billion expected to join them by 2050, maybe it’s time to take a step...
Jul 12, 2019•52 min•Transcript available on Metacast Do you live somewhere that might actually benefit from climate change? Rising temperatures and seas will produce losers and winners. Some parts of the world will see more moderate weather and economic gains, while others are already seeing sagging property prices and economic losses. “Many people think oh it’s just the temperature, but actually temperature affects everything,” says Solomon Hsiang of UC Berkeley. Hsiang co-authored a 2017 paper in the journal Science that outlines the impacts of ...
Jul 05, 2019•50 min•Transcript available on Metacast At what point does Planet Earth become inhospitable to life – let alone a flourishing human civilization? In his new book The Uninhabitable Earth: Life After Warming, David Wallace-Wells explores how climate change will impact not just the planet, but human lives – including how a five degree increase in temperatures would make parts of the planet unsurvivable. “The more I learned about the science the deeper I got into it… the more scared I was,” he admits, “and from where I sat as a journalist...
Jun 28, 2019•53 min•Transcript available on Metacast Produce, consume, discard; we all know the routine. Raw materials are extracted, produced into goods, and used – sometimes only once – before turning into waste. And maybe we think that recycling that Starbucks cup or Smartwater bottle is the best we can do for the planet. But that’s the wrong way to think about it, says John Lanier of the Ray C. Anderson Foundation. “Recycling is not the answer or the solution to advancing the circular economy,” Lanier asserts. It's an answer, but actually one ...

So how do we justify the environmental costs of world travel? Seeing the effects of global warming for yourself could be one argument for getting on that flight. For James Sano of the World Wildlife Fund, th...
Jun 07, 2019•52 min•Transcript available on Metacast Although many climate conversations talk about impacts on future generations, all too often those younger generations are not at the table or in the room. So how are young people taking charge of their climate future? For Isha Clarke, a high school student and activist from Oakland, California, by speaking truth to the senior U.S. Senator from her state. “I think that truth is respectful and that you can speak truth in a way that is compassionate and authentic,” says Clarke, who recently gained ...
May 31, 2019•53 min•Transcript available on Metacast “This is turning out exactly the way scientists predicted, with one exception: it’s happening faster than they thought,” says political analyst David Gergen, who served in four presidential administrations. “The question is what can we do rapidly that would alleviate this and be fair to all.” “There’s a lot of signs that voters, you know, they may not completely agree with the Green New Deal,” says Marianne Lavelle, a reporter with InsideClimate News, “but they’re not very happy with having poli...
May 31, 2019•52 min•Transcript available on Metacast This program was recorded in front of a live audience at The Commonwealth Club of San Francisco on April 30, 2019. During the 2016 presidential election, climate change barely surfaced as a campaign topic. This cycle it’s a different story. “It’s gonna be the first election where it's a major issue,” predicts former congressman Carlos Curbelo (R-FL). “I don't support it, but we can thank the Green New Deal for that.” Democrats have rallied around the Green New Deal and its lofty promise of a cle...
May 17, 2019•50 min•Transcript available on Metacast 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 fo...
May 10, 2019•52 min•Transcript available on Metacast 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 ...
May 03, 2019•53 min•Transcript available on Metacast 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? Guests: Ingrid Brostrom, Assistant Director...
Apr 25, 2019•52 min•Transcript available on Metacast 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 pra...
Apr 20, 2019•50 min•Transcript available on Metacast 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 Sc...
Apr 12, 2019•52 min•Transcript available on Metacast 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 the...
Apr 05, 2019•50 min•Transcript available on Metacast 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 Tes...
Mar 29, 2019•50 min•Transcript available on Metacast 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” a...

Climate scientists, communicators and educators join us to talk about about why, after one of the hottest years on record, the country has suddenly gone into deep freeze. On today’s Climate ...
Mar 08, 2019•50 min•Transcript available on Metacast From floods and fires to heavy snow and hurricanes, recent years have brought a raft of extreme weather disasters costing the U.S. hundreds of billions of dollars in damages. How do we fight back? The mayors of three cities on the front lines of climate change – Houston, Miami, and Columbia, South Carolina – discuss what their cities are doing to recover, rebuild and prepare for the next mega-storm. And Seattle Times reporter Jon Talton explains why he thinks fighting climate change should be ou...
Mar 01, 2019•52 min•Transcript available on Metacast Fighting climate change isn’t cheap. Where’s the money coming from? Major philanthropic organizations like Hewlett and Bloomberg are at the forefront of addressing climate change, but could smaller funders be more in touch with grassroots needs? Are big donors out of touch – or just stretched too far? Where is the money coming from, where is it going, what are the biggest wins and what missteps are being made along the way? Greg Dalton is joined by donors big and small for a discussion on harnes...
Feb 22, 2019•50 min•Transcript available on Metacast 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 ...
Feb 15, 2019•52 min•Transcript available on Metacast 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, eng...
