Massachusetts policy makers, community advocates and business leaders are coming together for this not-to-bemissed sendoff to our delegation as they head to Germany to promote carbon pricing at the Bonn Climate Change Conference. After our nation’s withdrawal from the Paris Accord, it is increasingly imperative for our state to demonstrate its leadership in reducing carbon emissions.

The keynote speaker will be Naomi Oreskes, a professor at Harvard University. A world-renowned geologist and historian of science, she is the author of more than 100 scholarly and popular books, articles and opinion pieces. Her next book, Science on a Mission: American Oceanography from the Cold War to Climate Change, will be published by the University of Chicago Press.

Cost: $250. Location: 61 Exeter St., Boston. For more information, visit CommittingToClimate.org.
