• “A Fresh Start for Our Cities” featuring Bill McKibben ’82

    PIPER AUDITORIUM, GUND HALL 48 QUINCY ST. CAMBRIDGE

    For over 40 years, Bill McKibben has been raising the alarm about the climate crisis, starting with his groundbreaking book, The End of Nature. Now McKibben says, for once in his life, he is spreading good news. In his latest book, Here Comes the Sun, he explains why the recent boom in solar and wind power has given him hope for the planet's future, and he implores everyone to buy in. We hope you can join us for this inspiring and important conversation. This event is supported by the Melissa Kaish and Jonathan Dorfman Makers Fund. It is co-sponsored by the Salata Institute for Climate and Sustainability through its Climate Crossroads: Debating Energy’s Next Frontier series, bringing leading voices confronting the intertwined challenges of climate change and the global energy transition to Harvard University.
