We Have No Idea Where the Tipping Point Lies

Something important to remember, brought to you by a George Monbiot thread. We don’t really know at what point things start crashing down, we just know it’s close and urgent.

1.5C is an arbitrary figure. There is no guarantee that this is a "safe" level of global heating, below the threshold between one climatic state and another. It could be 1.383C. Or 1.649C. Because these are highly complex systems, we have no idea where the tipping point lies. […]

It means we must treat the threat of irreversible climate breakdown as a global emergency, with immediate and drastic measures to leave fossil fuels in the ground, get livestock off the land, allow the rapid drawdown of carbon through reforestation.
