Basically, my objection to major legislative action to curb climate change isn't political exactly. It's that the measures that would have to be taken to actually have a meaningful impact on the climate would have to be more heavy-handed and extreme than the situation warrants. I'm not as convinced as Rod that the potential impact of climate change is catastrophic. Part of that is just my upbringing; my grandfather's a geomorphology professor emeritus at Cornell. Whenever climate change would come up in conversation he'd always point out that the earth, in terms of geological time, is in a relatively cool period at the moment. That aside, it seems hard to measure the cause and effect relationship between carbon caps and climate change.
