An email from Lenny Bernstein, ExxonMobil Chemical Engineer to the Director of the Ohio University Institute of Applied and Professional Ethics that discuses how Exxon was aware of climate change fueled by the fossil fuel industry back in 1981. In his email, Bernstein refers to a giant natural gas field in Indonesia that ExxonMobil did not ultimately develop because it posed a risk of becoming the single largest source of CO2. Bernstein also mentions the Global Climate Coalition, a trade group engaged in climate denial and his involvement with them in the 1990’s.
