Activists with Boston Rising Tide hung a 30 ft banner reading “System Change Not Climate Change” from Harvard Bridge during the final days of the COP15 conference. “The United Nations process has systematically failed the world’s marginalized countries and consistently excludes those that would dare support and fight on behalf of those countries,” said David Bukett of Rising Tide. “We need system change to create a world which is truly just and sustainable to solve the climate crisis.”
