If the following all were true, I’ll admit I’d be concerned:
1. the world really is going to heat up “dramatically” after 2009;
2. this is a man-made cause — or, at least, is more than minimally so, as opposed to being due to historically normal non-andropogenic actions (sun cycles, production of greenhouse gases by animals, plants, volcanoes); and
3. the warming will have a NET OVERALL negative effect on human quality of life.
I believe none of these things as of today. I’m open minded, but until someone convinces me of all 3, I cannot be simultaneously (1) emotionally honest and (2) worried.
Edit: andro- should be anthro-.
