lets not call it global warming but 'global climate change'
the world and nature is reacting to the increase of CO2 and although the plant life is trying to compensate we are also destroying the very system that will correct the imbalance.
what is even more urgent is our dependance on non renewable fuels 'oil coal etc.
if we do not use the carbon tax or any other system to change our entire society to a renewable fuel scource we as a life form are doomed .
Just as the many ancient civilaisations also died as a result of an over sophiticated society being dependant on a drying up scource of energy ie. wood from trees,or cultivating on such a scale, that they altered the local weather patterns and drought reduced the civilaisation to ether die or scatter.
