In 1977, Exxon's own scientists ran the numbers and reached a startling conclusion: burning fossil fuels would warm the planet, melt ice caps, and reshape global climate within decades. Their internal research was rigorous, peer-reviewed, and ahead of the public scientific consensus. Then the company spent the next forty years funding doubt.

This Part 2 documentary traces the deliberate pivot from in-house climate science to a coordinated misinformation campaign — the PR firms hired, the front groups funded, the manufactured "debate" that delayed policy by a generation. It's a case study in how a corporation can hold a secret of planetary consequence and still convince the public that the science is unsettled.

What makes this worth watching is the documentary trail: leaked memos, court filings from the InsideClimate News investigations, and the eventual Congressional testimony. You learn not just what Exxon knew, but how internal scientific knowledge gets translated into external corporate strategy — a pattern that recurs in tobacco, asbestos, and opioids.

Heads-up: this is a tiny channel (1 subscriber) and Part 2, so you may want to find Part 1 first. The production is modest, but the underlying story is one of the best-documented corporate cover-ups of the modern era.
