Green House Gasses

Carbon Dioxide

50%

Methane

18% 27x CO2

Nitrous Oxide

6% 150xCO2

Synthetic Gasses (CFC’s) and other

26%

6% CFC10,000x CO2

CFC substitutes 300-5,000xCO2

“Careful measurements have confirmed that CO2 is increasing in the atmosphere and that human activities are the primary cause…

    • … 31% increases can not be explained by natural causes. CO2 concentrations are now likely higher than any seen in the in at least 420,000”
