What the oil industry hides from the public - Stephanie Honchell Smith

Uncover the oil industry’s decades-long campaign to discredit climate change science regarding the danger of fossil fuels. -- Throughout the 1980s, oil industry reps discussed the dangers of burning fossil fuels, acknowledging the risk their product posed to the future of humanity. However, instead of warning the public or pivoting towards renewable energy sources, they doubled down on oil — and launched a decades-long campaign to discredit climate change science. Stephanie Honchell Smith digs into Big Oil's tactics. Lesson by Stephanie Honchell Smith, directed by Sofia Pashaei.

And so for the next several decades, gas-powered cars dominated the market. Can electric cars reclaim their place on the road? Daniel Sperling and Gil Tal investigate.
