Right now the most ardent of AGW advocates are citing a 1-1/2C increase since 1880. Sure, someone could "claim" the entire planet is going to burst into flames by next week but mho is that we've got better things to do.
Many scientists are intentionally choosing to communicate unrealistically optimistic models to the public in order to encourage action now, because there is a non-zero chance that immediate action might allow humanity to survive.
Those optimistic models are based entirely on fantasy, though. They often rely on forms of carbon capture that we don't have now and might even be physically impossible, for instance. They almost all assume that we will suddenly start making rapid progress in the future, without any justifications for those assumptions.
Everything I linked in my post already addresses these optimistic models and points out why they're false. The truth is that those optimistic estimates are inaccurate, according to our current data.
