Bill McKibben

Author, Activist & Founder

Bill McKibben, an author and activist, is the founder of Third Act, which organizes people over the age of 60 for action on climate and justice. He also helped found, the first global grassroots climate campaign, which has organized protests around climate change on every continent, including Antarctica. McKibben’s 1989 book, “The End of Nature,” is regarded as the first book for a general audience about climate change. He has since written 20 other books, and his work has been featured in publications like the New York Times, the New Yorker and Rolling Stone. He serves as the Schumann Distinguished Scholar in Environmental Studies at Middlebury College, as a fellow of the American Academy of Arts and Science, and he has won the Gandhi Peace Prize as well as honorary degrees from 20 colleges and universities. McKibben will speak on the need for applying pressure that “shakes people up and makes them get real,” and “bring(s) people together and pushes them forward.”

Søren Hermansen

Community Energy Leader & CEO, Samsø Energy Academy, Denmark

Søren Hermansen is the director of the Samsø Energy Academy on Samsø Island, Denmark. He was the driving force behind the transformation of the island into a carbon-negative island through the use of alternative energy sources. Over a 10-year period in the early 2000s, Hermansen helped set up investment plans for island residents to buy into a collection of alternative energy sources, including solar. In addition to other measures, residents bought shares in new land-based wind turbines. With 11 wind turbines on the island and 10 offshore and, together with other sources, Samsø generates enough energy to meet the entire island’s electricity needs.

Melissa Hoffer

Climate Chief of Massachusetts

Melissa Hoffer is the first-ever Climate Chief of Massachusetts. Gov. Maura Healey appointed Hoffer on her first day in office, signing an executive order that created this first-in-the-nation climate chief position. Prior to her post with the state, Hoffer served in the Biden Administration as Acting General Counsel of the Environmental Protection Agency. Before assuming the Climate Chief post, Hoffer, who is an attorney, led then-attorney general Healey’s lawsuit against ExxonMobil alleging the company deceived the public about climate change. Hoffer has described climate change as “a defining issue of our time,” and will share some of the things the Healey Administration is doing to address it.


The Cape Cod Climate Change Collaborative’s mission is to help reduce ways in which the Cape Cod region contributes to climate change and to protect our region from its potentially devastating impacts by convening, communicating, collaborating, advocating and activating people toward action.
