My intent is not to argue that global warming is real but to question the cause. I offer no defence for environment polution and I support any possible reduction of any crap that we put into our living space.
That being said we must pause and take a (cough, cough) deep breath:
We are being bamboozled by bad science that is ignoring many facts.
The Earth has been undergoing climate changes ever since its creation and it will continue to do so as long as time itself exists. To say a certain summer was the hottest on record means nothing if that record only goes back 100 years. We know that climate changes follow cycles that are far beyond our control. 25 thousand years ago most of North America was under a glacial blanket and woolly mammoths roamed it's perimiter. 1000 years ago North America was warm enough that Lief Erikson found wild grapes growing on the Northern tip of Newfoundland.
Today there are neither woolly mammoth or Newfoundland grapes. Tomorrow there may be neither polar bear or mankind. We must do what we can but before we take too big a guilt trip we must also understand that our power to change nature is limited.
