He kind of addresses your point in the second video
in that he looks at the likelihood of global climate catastrophy. He actually argues that it seems more likely than not, but I wouldn't agree with him.
There's plenty of politics and agendas throughout the scientific world. Even if we could agree that there was a scientific consensus that climate change was very likely to happen, I'm not sure if I would put entirely that much stock in it.
The reason for this is that, even if the best climate models give high probabilities of disaster, by definition, they are predicting things outside of their normal range of use.
That said, even if you think the likelihood is as low as 10%, it'd still be well worth spending a few billion on sorting it out.
