Internal files add to evidence of an ExxonMobil climate deception campaign

Internal documents released as part of a Massachusetts lawsuit against ExxonMobil reveal that the company's scientists warned executives in 1988 that climate action could harm the company, yet the oil giant continued to publicly question climate science while privately understanding the risks. The newly disclosed files, along with previously known documents, provide evidence supporting claims that ExxonMobil knowingly deceived the public about climate change for decades, strengthening cases by cities and states seeking to hold oil companies financially responsible for climate-related damages.
