National Geographic Releases Alarming Climate Change Movie 'Before the Flood' On YouTube (youtube.com)

National Geographic's Climate Change movie "Before The Flood," featuring actor-activist Leonardo DiCaprio, can now be viewed freely on Youtube. 

 One of the most interesting points in the movie comes at around the 23 minute mark.

 At 23 minutes, scientist Michael E. Mann, famous for co-discovering the "hockey stick graph" via eigenvector based climate field reconstruction (CFR), recounts how media like the Wall Street Journal demonized him for his research, how he received death threats from unknown sources, how Congress grilled him about whether his scientific methods are credible, and how he even received an envelope in the mail with strange white powder in it.

 The movie is worth watching because it shows very clearly that a) man-made climate change is happening and that b) the negative effects of climate change are already impacting many areas of the world.
