Garth Lenz at TEDxVictoria

This talk is a bit difficult to watch as Garth Lenz comes close to breaking down a couple of different times during his talk. Keep in mind, as he talks, that atmospheric carbon is at 395ppm, the target to maintain civilization on the planet is 350ppm, and last spring saw recording stations report spikes of over 400ppm. If everything stopped right now, we're still on target for 21 metres of sea level rise, a dramatic explosion in extreme weather events, a huge expansion of deserts, wild changes in fresh water availability and an inability to grow many corops and certainly not consistently. And all that within the projected lifespan of our children.
