Exxon Knew About Climate Change in 1977

Corporate Receipts

ExxonMobil's own scientists accurately predicted global warming decades ago, while the company publicly funded climate denial.

Public Statement

Oil companies denied climate change was real or human-caused. They said the science was uncertain and more research was needed.

What the Records Show

Internal Exxon documents from 1977 onward show their scientists accurately modeled CO2-driven warming. A 2023 Science paper confirmed Exxon's internal projections were remarkably accurate. Meanwhile, Exxon spent millions funding climate denial organizations from the late 1980s through the 2000s.

Significance

One of the most consequential cases of corporate knowledge suppression. Multiple lawsuits ongoing. Internal documents obtained through litigation and investigative journalism.
