Forget the Mayan end of the world rumors. It's modern humans who are destroying the environment with carbon emissions. The increasingly unstable climate poses a dire security risk inexplicably ignored in the 2012 electoral campaigns. Have Americans implicitly agreed to pay for weather related damage vis a vis insurance, taxes and ruin?
Coal and unconventional natural gas (i.e. fracked) are the hardest on the environment (Nature, "The Alberta oil sands and climate," Neil C. Swart & Andrew J. Weaver, 19 February 2012). Are we allowing those industries to value their profits over our children's futures? Environmental impact must be part of the economic equation - otherwise "we the people" are underwriting our own destruction.
To quote Mssrs. Swart and Weaver "If North American and international policy makers wish to limit global warming to less than 2°C they will clearly need to put in place measures that ensure a rapid transition of global energy systems to non-greenhouse-gas-emitting sources, while avoiding commitments to new infrastructure supporting dependence on fossil fuels."
