1
THE ENGINE AND THE ATMOSPHERE
2
OUTLINE To show the direct relationship between engine emissions and carbon dioxide concentrations in the atmosphere---- and global warming. To relate the science to the society To provide courses of action.

5
The real planet we live on
6
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?
7
Burning hydrocarbon fuels MUST produce carbon dioxide and water
8
Thus, 1 gallon of gasoline produces 18 lbs of carbon dioxide RULE OF THUMB: 1 MILE~ 1 POUND OF CO2. It stays in the atmosphere for about 100years.
9
800 MILLION VEHICLES IN THE WORLD BURN 2 GALLONS EACH PER DAY That is about 5 billion tons (5,000,000,000,000 Kg) of carbon dioxide per year into the atmosphere!!
10
Our Atmosphere is very Thin
11
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%.
12
Mass of the Atmosphere is 5.2 thousand trillion tons
13
The vehicles added 5 billion tons of carbon dioxide per year. The mass of the atmosphere is 5.2 thousand trillion tons
14
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)

To understand the what is happening we need: Observation Theory Experiment Computation

UNDERSTANDING CLOUD FORMATION
22
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)
34
Kaya Identity N = population GDP = Gross Domestic Product E = energy usage C=carbon into the atmosphere
35
Population(N) GDP/N E/GDP C/E Projections for Kaya Hoffert et al “Nature” V.395 29 Oct. 1998
36
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……..)

ACTION 1.Internalization 2.Education/Research 3.Outreach 4.Involvement with policy 5. Examine Tradition

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.
