Climate change is one of those popular things for under-competent politicians and under-recognized "experts" to ride.  These people use science as the core criticism against religion while using hybrid science that is more like religion than science.  If I fail here to make that point well enough to at least raise a few serious questions, I will not repeat it.  The atmosphere is warming - markedly.  Carbon and other air-suspended compounds are increasing.  There is logic in the connection between filth and atmospheric warming.  But.  There have been many periods evidenced in ice and rock-soil that this has occurred on a number of occasions when humans could not have been involved.  Cleaning up emissions is a win-win-win approach but we have no idea what the cost-benefit would be at this time OR whether we are better off to get ready to accommodate climatic change than to try to stop it.  Many reasons...  but the one that will kill it is affordability relative to other must-do's.
