Droughts are a normal part of our weather pattern.
Plant's need CO2 to grow. The CO2 content of a greenhouse is well over 1,000 ppm. Significantly higher than the current alarming rate of 400 ppm.
The world produces more food supplies than it ever has.
Earth has had CO2 concentrations up to 4,000 ppm before. Know what it was like then? A big steamy rain Forrest. Saudi Arabia was a jungle.
The earth hade higher C02 concentrations before man arrived and will after man is gone.
But hey it is ok - be part of the uneducated that believe hurricane Sandy is part of climate change when hurricane concentration is at an all time low. Or that the drought is as well when we have had two other drought equally as bad in this century.
I know it is an important part of your Eco system yo buy into all of this. Carry on.
