I think a point very few of us dispute is that the earth is getting warmer. We also can, without question, show that warming correlates directly with a dramatic increase in CO2 which in turn corresponds to the use of fossil fuels. Griz, I agree with your point about using common sense and watching to see what happens. That is the basis of scientific method; hypothesis and observation. Our best efforts to predict what happens to our planet when we introduce increasing amounts of greenhouse gases such as CO2 to our atmosphere, predicts there will be a significant increase in temperature. Indeed that is what we happen to be observing. These greenhouse gasses may possibly not be the cause of our global warming because this planetary system is undeniably of a complexity none of us can claim to truly understand. Among other things, ice ages seem inevitably to come and go at relatively regular intervals, valcanoes provide their momentary disruptions to global systems, and as Wyxman points out, some theorize that increasing warmth causes more cloud cover and a corresponding albido effect that may mitigate other factors. We all necessarily must keep an open mind to the possibilities. Our passions for our strongly held beliefs can stop us from living Griz's wise advice about observation. For me though, for thousands of the world's foremost scientists steeped in the importance of common sense and observation, the CO2 - warming correlation is so striking, the observation so strongly matching the hypothesis, they, and I, cannot in good conscience walk away from the idea that this is indeed of our doing. Fossil fuel has revealed it's ugly side, it's hidden cost. Know thine enemy, for then you can defeat them. And that I believe we can do. So for sure you know my opinion. If I'm wrong, great... I don't really care, but I sure do care that we get this right as soon as possible so if necessary we still have a chance to do something. I must admit I do not burn wood only because of it's CO2 benefits. I happen to love the whole process; collecting, cutting, splitting, (not stacking though..) the smell, the excersise, and especially the art of knowing the wood, the weather, and my stove to burn cleanly and efficiently to produce comforatable heat. For me that's really what wood burning is all about. Fortunately for us, in our own small and enjoyable way, wood heat is also a part of the CO2 solution. But due to it's importance and urgency, I urge you all to continue this debate, to observe, to learn all you can. Our world may hang in the balance.
