Gasoline is 85.5% carbon1 gallon of conventional gasoline becomes 172 cubic feet / 4.87 cubic meters of CO2
Humans add about 25 billion tonne carbon dioxideto the atmosphere each year

The oceans have absorbed about 30 times more heat than the atmosphere since 1955
Global Climate Changechanges everythingCO2 changes plant behavior
Increases temperature of the atmosphere, the earths crust and the oceans Affects global hydro cycle
Summers will be scorchersThese maps show the projected increase in average daily July heat index relative to the present. The largest increases are in the southeastern states, where the models projects increases of more than 25F. A July day in Atlanta that now reaches 105F would reach 115F in the Hadley model, and 130F in the Canadian model.
