Scientists believe the 5 year global averages (the important things) are good to a tenth of a degree or so.

Man has created substantial warming by making greenhouse gases. How man's seemingly puny efforts can do that is explained here:
So we can also reduce this.
The fact that these guys are actually asking for strong government action is surprising, and indicates just how much we need to take this seriously.
