Carbon Dioxide Intercepts infrared waves going into space

Gasoline is 85.5% carbon 1 gallon of conventional gasoline becomes 172 cubic feet / 4.87 cubic meters of CO2
6
Humans add about 25 billion tonne carbon dioxide to the atmosphere each year

Globally, temperatures are projected to rise an additional

Summers will be scorchers
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 models projects increases of more than 25°F. A July day in Atlanta that now reaches 105°F would reach 115°F in the Hadley model, and 130°F in the Canadian model.
