Al Gore - 'An Inconvenient Sequel: Truth to Power'

The 45th vice president of the United States discusses why, after the 2000 presidential election, he decided to devote himself, body and soul, to the cause of raising awareness about the threat of climate change and promoting ways of combating it before it’s too late for our planet; how he wound up the subject of the Oscar-winning 2006 doc 'An Inconvenient Truth' and its sequel 11 years later; and why he thinks Donald Trump needs to resign immediately.
