>>in fact, most of the scientists that doubt global warming are in fact climatologists
I don't doubt that a bit, but do you have anything that supports it? I'd love to throw it in some people's faces.
Before you throw too much, note that there's a significant difference between a "climatologist" and a "climate scientist". In general, climatologists compile statistical records: precipitation, heating or cooling degree days, high temperature and low temperature records, streamflow, etc. They also perform statistical analyses of the records. (This doesn't mean they aren't scientists; it's a different aspect of science.)
Climate scientists generally study the processes which affect climate, locally, regionally, and globally. This usually involves more modeling, use of different kinds of observational data (remote sensing, atmospheric sounding), and a lot of comparisons to the statistical archives compiled by climatologists.
Please note that I said "generally" in both cases; I'm sure that there are climatologists and climate scientists that don't fit into these generalities.
I've always wondered why there seems to be a disparity in the climatologist view of climate change compared to the climate scientist view. I suspect that it's partly due to the "inertia" of climate data -- it takes years to decades for a trend to assert itself in the day-to-day, week-to-week, month-to-month, and year-to-year data. Climate scientists may take a longer view, decade to century scale.
There's a couple of other things you can use, also.
There's three choices; the globe warms, cools, or stays the same. The last isn't going to happen, so you're basically down to two choices. Either one is going to throw people into a tail spin.
Plus, if you look at the earth's geologic history, the planet has usually been significatly warmer for long periods of time that it is now. We are technically in a cooler than average period. Propose to these people that the Earth is simply returning to it's naturally historically warmer state. Then you could ask them what caused the earth to be warmer then?
I don't think that people are in real denial that there is some warming occurring at the present, but the cause and just what there is that can be done about it are what's causing the controversy. There is also the impendng ice age hysteria that was rampant in the 70's based on the same short term temperature trends. Many younger people wouldn't be aware of that.
My experience is that the meteorologists at the NWS find the global warming issue to be a real blood pressure raiser. The ones I've talked to don't believe it and get pretty riled when it's mentioned.
