"Climate change is not some academic thing, it's pervasive – you see the signs of change everywhere,” said Ben Santer, a climate scientist at the Lawrence Livermore National Laboratory. “It’s profoundly sad that future generations may not experience the coral reefs or these fragile, high alpine environments in the same way that we did, and we’ve experienced these changes over a human lifetime.” Santer joined Jane Lubchenco, former administrator for the National Oceanic and Atmospheric Administration, to discuss extreme weather and the future of the warming planet. While hurricane and tsunamis will become more intense, heat waves are among the most damaging natural disasters, according to Lubchenco. But there’s still hope. “Many more people are beginning to see climate not as an economic issue, not as a political issue, but as a moral issue,” Lubchenco said. “Changing the way we think about the problem, I think, is part of the solution.” Jane Lubchenco, Former Administrator, National Oceanic and Atmospheric Administration Ben Santer, Climate Scientist, Lawrence Livermore National Laboratory This program was recorded in front of a live audience at The Commonwealth Club of California on December 11, 2013 Learn more about your ad choices.

"I don't think there's any right to emit, I think there's a right to development," said former World Bank chief economist Lord Nicholas Stern, a professor at the London School of Economics. “To emit is to damage – I don’t see that there's a right to damage.” Stern spoke about the economics of climate change, alternative energies, the carbon bubble and the growing global population before accepting the 2013 Stephen Schneider Award for Outstanding Climate Science Communication. Few people have impacted the discussion of the economics of carbon pollution more than Stern, who authored the highly influential 2006 “Stern Review,” which concluded that the costs of inaction were far greater than the costs of action when it comes to climate change. “Having no policy of any serious strength on climate change is essentially to do nothing about the biggest market distortion, the biggest market failure the world has ever seen,” he said. The $10,000 Stephen Schneider Award is given every year in memory of the late Stanford researcher Stephen H. Schneider, a founding father of modern climate science. The award recognizes people that create new understanding in the physical and social sciences, and communicate to a broad public.

"This country has forgotten rural America for far too long," said U.S. Secretary of Agriculture Tom Vilsack. Although the U.S. has had the best farm economy in the last 5 years, rural America hasn’t done as well, he said. This conversation with Vilsack and U.S. Trade Representative Michael Froman involved the Farm Bill, the Trans-Pacific Partnership, GMO labeling and other economic tensions. “Our exports are driving about a third of our growth in this country right now,” Froman said, emphasizing the need to keep opening markets, ensuring level playing fields and enforcing our trade rights. But climate change presents problems for agriculture and trade that are intensified by growing populations. “We face a huge global challenge of increasing food production by 70 percent in the next 40 years with less water, with more intense weather patterns – it is going to require a global commitment,” Vilsack said.

“Fear of fracking is rampant,” said KQED science editor Craig Miller when asked about California’s energy headlines of 2013. But more electric vehicles are on the road and the cap-and-trade market is about to enter its second year – the rest of the country is watching California’s approach to a clean energy future. “Part of this is a response to lack of federal leadership,” said Andrew McAllister, a member of the California Energy Commission. “We’re having to go down this route because there’s not a federal climate policy.” This conversation covers the ups and downs of power in California during a pivotal year, and what it means for the future. “This pattern where we decide that there’s some competition between jobs and environmental protection – this is a stupid idea,” said Amy Myers Jaffe, executive director of Energy and Sustainability at UC Davis.

"The Bay Delta debate sucks all the oxygen out of the water discussion," according to Lester Snow, executive director of the California Water Foundation. While the Bay Delta needs to be addressed, it doesn’t fix California’s long-term problems, Snow said. With population increasing in a parched state, California needs to focus on efficiency, groundwater policy and wastewater recycling. Some areas will eventually turn to desalination plants, but "there is a real risk to doing it too soon," according to Heather Cooley of The Pacific Institute. This conversation explores the solutions and resilience the state needs to prepare for extreme weather and declining snowpack. When it comes to climate change, “water’s going to be the thing that translates it for people into a real experience,” said Bob Wilkinson, an adjunct associate professor at UC Santa Barbara.

In 1968, Graham Nash left his native England and flew to Los Angeles to visit his enchanting, brilliant girlfriend, Joni Mitchell. With one jet-lagged impromptu jam session in her house in Laurel Canyon, the magic of Crosby, Stills and Nash was born. After that, his life would change forever. From the sounds and feelings to the girls and parties, Nash conveyed the unforgettable adventures of his life through his autobiography, Wild Tales: A Rock & Roll Life. But it's not just a relic of history. His lyrics inspired generations to "teach your children well," and Nash is a living reminder that we are the stewards of our own future. He came onto the music scene in a generation that was pushing social norms and has since become a true renaissance man. Nash co-founded Musicians United for Safe Energy and lead its famous No Nukes concerts. He maintained a parallel career in photography as a collector, a pioneer of digital imaging and an artist, capturing the often overlooked elements of everyday life. An exclusive peek into the wild tales and issues facing today's environmental movement with one of the greats of rock and roll, art and social activism.

“We have been fracking in California for 60 years and we have done it safely,” according to Paul Deiro, an energy lobbyist with KP Public Affairs. “We believe in transparency, disclosure, notification.” The state is on the verge of a huge energy boom, poised to hydraulic fracture, or frack, across much of the coast and Central Valley. Signature of a new fracking regulation bill, SB4, has upset advocates and opponents alike. “Investing in getting more fossil fuels out of the ground is just bass-ackward right now,” said Annie Notthoff, California Advocacy Director with NRDC. But fracking is already occurring, and the purpose of the bill was to create oversight and transparency, argued State Senator Fran Pavley. “What I’m trying to do is put a public face on this,” Pavley said. This conversation reveals diverse opinions on the state’s evolving fracking debate. “This is not your father’s fracking,” Notthoff said. “This is a new day.” Fran Pavley, Senator, California State Senate Annie Notthoff, California Advocacy Director, NRDC Paul Deiro, Energy Lobbyist, Western States Petroleum Association Learn more about your ad choices.

“Every second breath comes from the ocean,” said Mary Hagedorn, a research scientist with the Smithsonian Institution and the Hawaii Institute of Marine Biology. Many people don’t realize how much we depend on the ocean for food, health and jobs. With climate change and pollution altering seas and coastlines, the speakers agreed we need to do a better job of monitoring these systems. Scientists and businesses have to work together, according to Michael Jones, president of The Maritime Alliance in San Diego. “There’s always going to be uncertainty with climate change, but uncertainty can’t be an excuse for inaction,” said Jason Scorse, Director of the Center for the Blue Economy at the Monterey Institute of International Studies. “This is immediate, this is now, this is accelerating, and the good side is people realize that.” Jason Scorse, Director, Center for the Blue Economy, MIIS Mary Hagedorn, Research Scientist, Smithsonian Institution/Hawaii Institute of Marine Biology Michael Jones, President, The Maritime Alliance, San Diego This program was recorded in front of a live audience at The Commonwealth Club in San Francisco on October 28, 2013 Learn more about your ad choices.

“We want skiers to literally help save the world,” said Porter Fox, editor at Powder Magazine. Climate change has already impacted the length and intensity of winters and reduced snowfall means many of the nation’s ski centers will eventually be forced to close, especially those at lower temperatures. Jeremy Jones, professional snowboarder and founder of Protect Our Winters, reminisced about a spot he revisited in Chamonix: “I used to be able to snowboard here.” This two-panel conversation first explores the science and personal experiences behind shorter winters, then looks at how ski resort CEOs are dealing with the problem. “If you’re going to allow carbon emissions to be free, in the end nobody’s really going to do anything,” said Mike Kaplan, president and CEO of Aspen/Snowmass. With the popularity of winter sports, the ski industry may be able to help communicate the impacts of climate change. “This industry gets it,” Kaplan said.

“Humans are problem-solving animals – you would never know it reading the press,” said environmentalist Paul Hawken. He and NY Times writer Andy Revkin discussed how attitudes have changed in the 25 years since NASA scientist James Hansen testified before Congress about human-caused climate change. “Right now, the attitude is that climate change is happening to us...instead of the idea that actually climate change is instead happening for us,” Hawken said. Some problems stem from lack of education, while others can be attributed to policies and mindsets. “It’s our social systems that impede progress,” Revkin said. “The technologies are there, to some extent, but how do you facilitate them?” The speakers presented a hopeful outlook in the face of rising seas and extreme weather. “Carbon is the element that holds hands and collaborates in nature,” Hawken said. “We’re going to have to be like carbon and hold hands and collaborate.” Paul Hawken, Author and Entrepreneur Andy Revkin, Writer, The New York Times Dot Earth Blog This program was recorded in front of a live audience at The Commonwealth Club of California on October 18, 2013 Learn more about your ad choices.
