1 gallon of conventional gasoline becomes172 cubic feet / 4.87 cubic meters of CO2

125 gallon makes one ton CO125 gallon makes one ton CO22

1 ton of CO2 easily fills up a 19,866 cubic feet / 556 cubic meters container

Global Climate ChangeGlobal Climate Changechanges everythingchanges everything

CO2 changes plant behavior

Increases temperature of the atmosphere,the earth’s crust and the oceans

Affects global hydro cycle

These 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 Canadian model projects increases of more than 25°F.

For example, a July day in Atlanta that now reaches a heat index of 105°F would reach 115°F in the Hadley model, and 130°F in the Canadian model.

Achieving carbon neutrality (the switch to clean energy) = 30 years?

Absorption of latent carbon (sequestration) = 7% of planet surface & 150 years?
