We don't understand climate and atmospheric dynamics well enough to fiddle about with such a delicate, chaotic system.<br /><br />Which also means we don't understand climate well enough to exclusively lay it at the feet of human CO2 production. Yes, our greenhouse gases do have an effect on naturally occurring climate variation, but we do not know the extent of that effect, nor the extent to which dramatically changing our societies will mediate climate change.<br /><br />If we stop all human production of greenhouse gases, a proposition that is probably not possible, climate will still change, as it did before humans produced GHGs. Unless we understand these nonlinear chaotic climate systems, any uninformed human response to perceived "global warming" could change the rate and direction of natural climate change in either positive or negative directions, with regard to human societies.<br /><br />Yes, we must reduce our dependence on fossil fuels, because they are, by definition, finite. And we must change our societies to operate within naturally occurring cycles of resource availability and waste dispersal. If we can accomplish these goals, greenhouse gas production will be significantly reduced as a by product.Michael A. Lewishttps://www.blogger.com/profile/04980105313542633114noreply@blogger.com
