Major fossil fuel companies have known for decades that their products—oil, natural gas, and coal—cause global warming. Their own scientists told them so more than 30 years ago.

In response, they decided to deceive shareholders, politicians, and the public—you!—about the facts and risks of global warming.

They repeatedly fought efforts to move the country away from fossil fuels. They slowed progress on the most important challenge of our time. And some continue to spread disinformation and obstruct climate policies even today. All while being aware of the role their products play in climate impacts.

These companies should immediately stop funding climate deception. They should bear their fair share of responsibility for the damage caused by their products.
