No clue George! The huge benefits to all of mankind from using fossil fuels is the sole reason for the success of today’s civilization, a huge decrease in human suffering and the vary survival of the species. Are humans increasing the carbon dioxide content of the atmosphere -yes. But show me the science that can definitively tie this to detrimental environmental effects. There are many prognostications and models out there but there is no proven scientific proof, as has been recently discussed by several leading climate experts. So far all the drastic issues you profess have been debunked and every climate model has proven to be wrong and inconsistent with realized effects. But keep drinking the Kool-ade and submitting to the shrill calls of the ecofreaks who want total control.
