I recently watched it, and was frankly quite surprised.
I don't agree with all his conclusions. And in a couple of cases I suspect his statistics and data were fudged a bit.
What was impressive to me was the scale of the glacier melt off.
Showing Glacier National park before and after pictures with 20 - 30 years apart was frankly a bit scary.
Great data, nice presentation, but if he'd really wanted to make a difference he'd of hired someone to do it instead of doing it himself. That makes it more about politics & less about global warming.
The really impressive thing to me was the co2 and temp data from polar ice cores going back the last 6 ice ages. WOW!
The conclusion that he missed, its that it IS a cyclic problem, on a really HUGE scale. And yes we are adding too it, and making it worse, but it won't continue climbing forever, its going to tip the other way. Each ice age clearly showed a climb of co2 & temp peaking then plunging very very quickly into a new ice age.
Then a long slow climb out until it peaked again.
That plunge is what I'm worried about, not the average temp of the USA being 130 degrees in 10 years, or all the polar ice caps melting. But we could be sliding into the next ice age at virtually any moment.
