Exxon scientists knew climate change was man-made, in 1977! Not only did they HIDE this knowledge, decades before it became an political issue, they also used it to plan contingencies and give themselves a competitive advantage by building for worse climate conditions, and all the time always denying the fact (still do) fossil fuels was the primary cause of climate change! The is magnitudes worse then the tobacco industry denying the health problems caused by smoking since it effect everyone alive and yet to be born. The most egregious thing is Exxon-Mobile is engaging their political defenders to fight for them (and it gets nastier as congress investigates states to stop Exxon investigations) instead of changing their position and do what all the other oil companies are doing. Completely unwilling to any change, like the NRA. Totally idiotic of them, since it hurts their public opinion and delays transitioning to less carbon emitting technologies. I hope they get serious burned. Sources Los Angeles Times Bloomberg report Washington Post ADDITIONAL: WP has a bunch of articles on this topic. #ExxonKnew ====================== JUICY ADDITION: Lamar Smith (R-Texas)... issued subpoenas to Schneiderman; Massachusetts Attorney General Maura Healey, who’d launched her own investigation of Exxon; and eight nongovernmental organizations. "It’s unusual for a congressional panel to interfere with a pending state investigation, says Senator Sheldon Whitehouse (D-R.I.)" SO, a member of the "Party of States Rights" (Republican) is using his power to force states investigating Exxons actions to kowtow.
