Sea Education Association president and former New Bedford mayor John Bullard presents Global Warming: What’s Going On Here? What Do I Do About It? on Thursday, July 3, free at 5 p.m. at the Chilmark Public Library.

Mr. Bullard, who adapted his presentation from Al Gore’s An Inconvenient Truth, served in the Clinton/Gore administration. He will summarize the science of global warming, the impacts already being felt, future threats and actions we can all take.

With Woods Hole’s Sea Education Association, Mr. Bullard spends six weeks on land teaching oceanography, nautical science and maritime studies followed by six weeks sailing the Atlantic or Pacific oceans on 135-foot tall ships serving as research vessels.

He previously was the head of the first federal Office of Sustainable Development. He now chairs the strategic planning group of the Massachusetts Ocean Partnership Fund.
