Introduction The world community is truly at a crossroads like never before faced in the history of our civilization. If we continue business-as-usual with the consumption of fossil fuels, then, according to the 2014 edition of the Intergovernmental Panel on Climate Change (IPCC)'s climate change report, grave consequences will almost surely ensue, including rising sea levels, extreme temperatures, flooding, drought, agricultural losses and, quite likely, violent conflicts among human societies. Delays may have already cost the world society USD$8 trillion.
Some who distrust the scientific consensus on climate change have taken heart at an apparent leveling off of world temperatures in the past few years. But it is now clear that this respite is short-lived, since 2014 is on track to be the hottest year on record.
