Students from Harvard and Yale protest their schools’ investment in fossil fuels. | Campbell Erickson/Fossil Fuel Divest Harvard Divestment is one of the fastest-growing movements in the fight against climate change. It’s only getting started. More than 200 climate activists brought the annual Yale-Harvard football game to a halt Saturday to protest both universities’ investment in fossil fuels. Carrying a banner reading “Nobody wins: Yale & Harvard are complicit in climate injustice,” students rushed to the 50-yard line and stalled play until police arrived and began arresting them.
