Okay, so it’s a few years old, but I’d never seen this series of videos by National Geographic before. I’m not convinced you can slice the impacts into 1 degree increments with any reliability, but this series does a nice job of getting the big picture across (much better than Lynas’ book, which I found to be too lacking in narrative structure):
- Could Just One Degree Change the World?
- 2 Degress Warmer: Ocean Life in Danger
- 3 Degrees Warmer: Heat Wave Fatalities
- 4 Degrees Warmer: Great Cities Wash Away
- 5 Degrees Warmer: Civilization Collapses
- 6 Degrees Warmer: Mass Extinction?
What’s uncanny is how much of what’s presented in the 1 degree video is already happening now.
This is a nice imagination, but i doubt civilization could be sustained with even 3+.
Even today with under 1 Degree, we see nations around the globe, collapse. Because of food prices or problems tied to climate change.
There are implications which have not been discussed previously.

Yep… Mark Lynas wrote “Six Degrees: Our Future on a Hotter Planet” – reviewed and blessed by RealClimate.
A few years ago I made a composite chart with the six degrees summaries and the IPCC chart – it is not video but shows the conclusions on one page. http://localsteps.org/howbad.html
Now I read that 2 degrees is inevitable and 3 or 4 is quite possible – and 5 or 6 cannot be ruled out.
And the Stern Report made nifty chart posted at http://localsteps.org/degree-impact.html – the the original source might be found in their archive
