Forty Yale students and graduate students met at 5 a.m. last Sunday to join the 50,000 people who gathered at Washington, D.C., to participate in the “Forward on Climate” rally.

Coordinated by members of Fossil Free Yale — a group that is pushing the University to refrain from investing its endowment funds in the fossil fuel industry — and the Yale Student Environmental Coalition, the trip called for President Barack Obama to reject the Keystone XL pipeline, a proposed expansion of the current Keystone Pipeline that transports synthetic crude oil and diluted bitumen from oil sands regions in Canada to the United States.

“Ooh, it’s hot in here. There must be some carbon in the atmosphere. Take action, take action and get some satisfaction,” Yalies chanted at the event, according to a press release written by members of Fossil Free Yale.
