How is this not a good talk?
- Reads from a script
- Wears a hat that shades his eyes
- Stiff even a little stilted delivery
And none of that matters. All the emphasis on polish and pitch and engagement and audio/visual presentation is irrelevant. It’s what he says that makes this a riveting talk. And I would hazard a guess that even if you strongly disagree with Hansen (and quite a few do) you would still find the talk riveting because he quickly focusses in on what the issue of climate change is about: to what extent are we affecting the Earth’s climate and what are the consequences to us and future generations?
Hansen is someone worth listening to because he has largely framed this debate (in the USA at least). He’s got a very interesting perspective: a life of science and reflection on what he has learnt and how that informs what he should do with the rest of his life.
