A new investigation has revealed more information about Exxon’s decades-long bid to conceal what it knew about global warming. The Los Angeles Times reports Exxon predicted in the late 1980s and early 1990s the Arctic would melt from climate change, reducing their operations costs by as much as 50 percent. A senior ice researcher for Exxon’s Canadian subsidiary told an audience of academics and government researchers in 1992, “potential global warming can only help lower exploration and development costs” in the Beaufort Sea.
