Respectfully suggest this is nonsense. No serious climate scientist thinks we are going to fall off a cliff. There will be huge costs, yes. Civilization won't end, no.
What people fail to grasp is that costs can be absolutely enormous but look like a blip compared to the effect of GDP growth in the long run. World War II is an example. The millions of deaths barely show up on a graph of world population. The huge losses barely interrupt the smooth rise of GDP. Similarly, climate change could knock 5% off GDP permanently, this would be "the world's biggest collective action problem" as I think Nick Stern put it, but it wouldn't stop human society getting much richer.
