NEW HAVEN, Conn. (AP) — Students alarmed by climate change are stepping up pressure on universities to pull investments from fossil fuel industries, an effort that is gaining traction at prestigious schools like Georgetown, Harvard and Yale.

The push that is underway at hundreds of schools began nearly a decade ago, and student activists increasingly have learned from one another’s tactics and moved to act amid worsening predictions about the effects of climate change on the planet.

Georgetown University’s board of directors announced this month that it will end private investments in coal, oil and gas companies within the next decade, and some faculty at Harvard have called for a similar shift. There were sit-ins and demonstrations last week at dozens of schools, including Gonzaga University, the University of Wisconsin, University of Pittsburgh and Cornell University.
