What is your comment on Greg Craven’s view on "How It All Ends" video?

depressing

The video does a superior job of assessing risk which the average citizen has limited grasp. And policy around global climate change is all about managing risk.

Perhaps the effectiveness of his approach comes from the fact that it is geared toward a high school audience which he does well balancing humor with some concrete logic and reasonable use of the scientific evidence we do have about Global Climate Change.

His follow-up videos do a good job of addressing the comments and push back from folks who do no share his concern about this issue.
