"Climate changes. Truth does not." That's the tagline for An Inconvenient Sequel, the follow-up to Al Gore's 2007 documentary An Inconvenient Truth. The documentary — which debuted at Sundance Film Festival — released its first trailer on Tuesday, and it couldn't be more timely. President Trump plays a prominent role in the trailer, which dropped on the same day that the president signed an executive order aimed at rolling back the Obama Administration's climate policies.
