GASOLINE OR COAL OR NATURAL GAS ALWAYS PRODUCES CARBON DIOXIDE AND WATER WHEN BURNED IN AIR Other products too in very small amounts.What are they?
Burning hydrocarbon fuels MUSTproduce carbon dioxide and water
Thus, 1 gallon of gasoline produces 18 lbs of carbon dioxideRULE OF THUMB: 1 MILE~ 1 POUND OF CO2.It stays in the atmosphere for about 100years.
800 MILLION VEHICLES IN THE WORLD BURN 2 GALLONS EACH PER DAYThat is about 5 billion tons (5,000,000,000,000 Kg) of carbon dioxide per year into the atmosphere!!
The Atmosphere • The atmosphere of the earth is mainly Nitrogen (78%) and Oxygen (21%) by volume. • Carbon dioxide (a green house gas) is only around 0.038%.
The vehicles added 5 billion tons of carbon dioxide per year.The mass of the atmosphere is 5.2 thousand trillion tons
i.e. one part of Carbon Dioxide per million parts of atmospheric mass per year. (in volume units it is nearly 0.7 ppmv/yr) This is for vehicles only (add power plants etc. and it comes to around 2 ppmv/yr)

IPCC 2007
To understand the what is happening we need: Observation Theory Experiment Computation
Artists provide insight too Studies of these and other paintings show that cloud cover was greater in the 19th century than it it is today

Carbon emissions are related to: • Population (N) • amount of carbon to make a unit of energy (C/E) • energy usage per unit of GDP (E/GDP) • GDP/capita (GDP/N)
Kaya Identity N = population GDP = Gross Domestic Product E = energy usage C=carbon into the atmosphere
Projections for Kaya Population(N) GDP/N E/GDP Hoffert et al “Nature” V.395 29 Oct. 1998 C/E
CO2 and global warming are due to:Population increase(demography, geography,economics,sociology,psychology,history….)Increase in standard of living(development,sociology,economics,business,engineering,government………… )The amount of carbon we use to produce the energy(engineering, chemistry,physics,materials science…….)The energy usage per unit of GDP(business, economics,engineering,operations research……..)

1990 5.9 billion tons of C added. • 2006 6.3 billion tons of C added. • To cut to 2 billion tons (the 1955 value) by 2100 with the anticipated rate of GDP/capita and power /GDP decline the carbon/power will have to be 10% of today’s value.
