Dire consequences may or may not result from man's co2 production over the past century. Perhaps only time will tell. The question we need to answer now is this: Do we wait ti find out or do we take action now? For many,myself included,it is clear that we cannot continue our current habits.International groups have called for immediate action on the part of countries producing the highest amounts of co2 today. Unfortunately, such calls to action are only slowly acted upon or even ignored by industrialized nations.
