> Very nearly 100% of experts in this field agree it's happeningNone of these "experts" have a track record of correct predictions that justifies taking their current predictions seriously. Remember we are not talking about the fact that the climate changes: yes, it does, it always has, and it always will (unless at some point in the distant future we learn how to control it accurately). We are talking about the dire predictions of catastrophe that have been made to try to justify spending many trillions of dollars on CO2 mitigation. Those predictions have never come true.

To know whether these were useful predictions, we would need to know more details. Did they predict when it would happen? Did they predict how it would spread? A prediction that "this will happen, some time in the future" is not very useful. AFAIK no epidemiologists were making predictions much more precise than that.
Looking at the actual frequency of epidemics of various sizes in the past, we might very roughly estimate that we will have one serious enough to involve a significant portion of health care resources once every decade or so. But you don't have to be an epidemiologist to do that; you just have to do the simplest possible extrapolation of the data. We had H1N1 about 10 years ago, and SARS about 18 years ago. That's still not a very strong prediction, but it would seem to be as good a basis for public policy discussion (which is to say, a fairly weak one but not negligible) as anything more complicated that has come from epidemiologists.
