Remove the financial incentive by declaring that becoming energy independent is a good idea anyway, and that using "Limited" resources such as coal and oil, at the very least, is taking it from our children and should be minimized wherever possible. Also, point out that developing new energy sources such as solar and wind will create many more jobs than cutting back on limited resources will cost.
We could even decide that the jobs related to the limited resources ARE going away regardless, it's just a matter of time (by definition) and that we can either slowly ween the work force off now or face (at some point in the future) having all those jobs forcefully terminate at the same time (Our children will be jobless instead of us).
Oh, finally, is there really something wrong with leaving a decent amount of oil in the earth just in case we find something amazingly useful for it--something more important than driving an SUV 3 blocks to the store?
Now, once you've based your politics on this very logical approach, how many arguments against global warming go away simply because there isn't any financial reason to keep the argument in the news?
I'm not saying it will change everyones mind at once, but there is no doubt in my mind that within 5 years there would be no public debate on the subject whatsoever.
