Climate Change Elevator Speech

On a recent post Judith Curry challenged commenters with this question: 

How would you explain the complexity and uncertainty surrounding climate change plus how we should respond (particularly with regards to CO2 emissions) in five minutes?

 The video was an impressive offering from John Shewchuk, and I thought it worth sharing here.

    A brilliant video. A delight to watch and chock full of common sense and real facts.
    It should be required watching in our schools and universities 🙄. Fat chance😱

    Ron. I just came across this post and I am honored by it. Thank you for you work and your “science” discussions.

      John, I have spent many hours reading comment threads on various blogs. Seldom have I been so delighted as when discovering this gem of yours. Thank you.

        Thank you once again. I started last year when I could no longer just sit back and watch what is going on. These are the other videos I uploaded. Most are created by me — and except for one where I talk — mine are relatively short and have music backgrounds to help get the attention of the younger generation … Best regards.
