IPCC report: 'now or never' if world is to stave off climate disaster

2. They're just guessing.

This whole "stave off the worst ravages of climate breakdown by acting now" is a wildly optimistic guess and an assumption that we haven't overlooked even more feedback loops already in motion and tipping points already toppling over, processes that will continue inexorably onward regardless of what we do.

Since every new revelation falls into the "faster than we anticipated" side of the equation, I'm far less convinced that we haven't already passed the point of no return. But we're not even trying to hit the brakes, so it's all a moot point. We're doomed.
