Exxon and CEO Tillerson have been harassed for years about AGW. Tillerson first succumbed to the pressure in a 2009 speech when he said that he was for Carbon Credits. He has been for Carbon Credits since.
I guess the problem will arise when SoS Tillerson will be asked about Carbon Credits. He will of course have to flip on the issue and he will of course be beaten up by Big Media for doing that.
And that assumes that Trump will stay firm on the opinion that AGW is a hoax, or his latest opinion, that nobody really knows.
I think Trump will say FU to the AGW crowd and Tillerson will fall in line.
Trump has been consistently America First, and the Paris Accords, etc are not.
