The fourth topic, climate change, was introduced in a session with President L. Rafael Reif. MIT Corporation member Songyee Yoon, PhD ’00, turned the conversation to the Climate Action Plan Reif announced in May, outlining MIT’s role in getting the world to a net-zero-emissions economy, devising adaptations to mitigate climate change’s effects, and educating future MIT graduates to tackle both areas. “It is a serious challenge that they are inheriting from our generations, and we need to equip them with the tools to figure out how to address this challenge,” Reif said.
