Well I’m not sure anything is *completely* understood in science :)
But your point is well taken. Certainly the source of my interest is time frame, which is paramount. I’ve found little to persuade me there isn’t a general warming trend, but I’m not convinced there isn’t time to develop a better understanding and thus better solutions. The argument of skeptics seems to be we’re nowhere near a tipping point and we need a far better understanding of all the moving parts before any solution is viable. I sure hope that’s right because we’re not doing anything substantive for a while.
