Exxon Mobil lied to the public for decades about the threat of climate change.

Should we give it the corporate death penalty?

A new study out of Harvard has confirmed that fossil fuel giant Exxon Mobil intentionally misled the public for decades about global warming.

The study looked at Exxon's internal communications and public statements between 1977 and 2014 - and found a stark difference between the two.

"For example, accounting for expressions of reasonable doubt, 83% of peer-reviewed papers and 80% of internal documents acknowledge that climate change is real and human-caused, yet only 12% of advertorials do so, with 81% instead expressing doubt."

Shouldn't we bring back the corporate death penalty for companies like Exxon?
