My friend Hal Bauer recommended this video. It depicts the reality of global warming—a good basic explanation for someone who hasn’t studied the subject, but with new information to some (including me) who think we are well-informed.
It runs for more than 90 minutes, which is a bit long to watch on a small screen. But it’s broken up into brief episodes, showing the actor Leonardo DiCaprio’s world travel to educate himself about the subject.
The video ends with the USA and China, the world’s two largest industrial economies and the two largest producers of greenhouse gasses, agreeing in principle do set limits. This was before the election of Donald Trump, who has said global warming is a hoax promoted by China to undermine the U.S. economy.
