Not evidence. I want you to make a precise claim.
For example, "because CO2 is a greenhouse gas, and because there's a lot more of it around than there used to be, that CO2 cascades into a warming event" is a not-quantified claim. It's not precise enough to be falsifiable (which is how a lot of people like it, but that's a tangent).
A quantified equivalent would be something along the lines of "We expect the increase in atmospheric CO2 from 300 to 400 ppmv to lead to the increase of the average global temperature by X degrees spread over the period of Z years so that we forecast the average temperature in the year YYYY as measured by a particular method M to be T with the standard error of E".
Note that this is all claim, no evidence (and not a model, either).
Yes it is. For example, if CO2 concentrations and/or global temperatures went down by much more than the measurement uncertainties, the claim would be falsified.
