Eco-conscious at WPI grumble about grad speaker

But Roger S. Gottlieb, a philosophy professor at WPI, criticized [Exxon] for funding a campaign to cast doubt on global warming.

For example, the Union of Concerned Scientists reported in 2007 that the oil giant had funneled $16 million to a campaign to do just that.ExxonMobil also has a record of polluting, Mr. Gottlieb said.

He was one of more than a dozen faculty members who wrote a letter to WPI's president, protesting the choice of Mr. Tillerson as commencement speaker.

In his 30 years at WPI, Mr. Gottlieb said, he has never been so opposed to any commencement speaker.

"Clearly, humanity is in a terrible situation with our dependence on fossil fuels," the professor said.
"It's about making a speedy, rational and moral transition," he continued. "What Exxon has done is to try to slow down that transition."
