Big Oil braced for global warming while it fought regulations

A joint investigation by the Columbia University Graduate School of Journalism’s Energy and Environmental Reporting Project and the Los Angeles Times earlier detailed how one company, Exxon, made a strategic decision in the late 1980s to publicly emphasize doubt and uncertainty regarding climate change science even as its internal research embraced the growing scientific consensus.

An examination of oil industry records and interviews with current and former executives shows that Exxon’s two-pronged strategy was widespread within the industry during the 1990s and early 2000s.

As many of the world’s major oil companies — including Exxon, Mobil and Shell — joined a multimillion-dollar industry effort to stave off new regulations to address climate change, they were quietly safeguarding billion-dollar infrastructure projects from rising sea levels, warming temperatures and increasing storm severity.
