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 CO 2

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

We are here Globally, temperatures are projected to rise an additional 2 – 5°C in the 21 st Century

Summer Arctic Sea Ice NASA Goddard Space Flight Center

Greenland is melting NY Times June 8, 2004

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.

The oceans have absorbed about 30 times more heat than the atmosphere since 1955

The atmosphere now holds 30% more carbon than a century ago Human emission rate in billion tC/yr time equilibrium Latent atmospheric Carbon is about 188 billion ton Earth absorption rate in billion tC/yr de-carbonization pathway
