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
Humans add about 25 billion tonne
carbon dioxide
to the atmosphere each year

The oceans have absorbed about 30 times more
heat than the atmosphere since 1955
Global Climate Change
changes everything

CO2 changes plant behavior

Increases temperature of the atmosphere,
the earth’s crust and the oceans

Affects global hydro cycle
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.
