In 1965, the Surgeon General published a report linking cigarette smoke to cancer and other deadly diseases. But despite all this scientific evidence, the tobacco companies managed to hide the truth from the public for decades.

The key wasn't to disprove the science, but simply to obscure the facts and encourage doubt. The tobacco companies created the appearance that there was a scientific debate when none existed.

Sound familiar? This is exactly what climate change deniers are doing today. They are creating doubt in the public's mind even though real scientists have provided overwhelming evidence that climate change is a real and urgent danger.

Speak out! Let's not let it take decades before the public knows the truth about climate change. Pledge to speak out against deniers and tell the truth about the climate crisis.
