Central London during the killer smog, December 1952. At this point, visibility is less than 30 feet. During the height of the smog, people could not see their own hands or feet, and buses had to be led by policemen walking with flares.Credit: 'When Smoke Ran Like Water', by Devra Davis, Perseus Books

Research by Rutgers University's Paul Lioy and others shows that as the amount of smoke and pollutants in the air shot up during the week of Dec. 5, 1952, so did the death rate in greater London. Estimates say the smog killed anywhere from 4,000 to 11,000 people. Credit: Paul Lioy, Rutgers University
In what ways are both excess and insufficient ozone bad?
How does geography and sunlight make pollution problems worse?
How is the air in CA? What are the problem areas?
What is happening to the ozone hole? Getting larger, smaller?
How do cars pollute the atmosphere? How have cars improved over the past 20? years? If cars have improved, then why is the air not cleaner?
What are the human health consequences of air pollution?
Is there a common signature of (air) pollution with economic development?
How did the US manage to get a handle on air pollution?Air Pollution lecture highlights
Air getting better despite lots of factors that increase the difficulty to improve
London Gray Smog
LA Brown Smog
Coal burning power plants
Production of smog forming chemicals is approximately constant. Air mixing attributes changes the impact of the smog.
Some cities are plagued by poorer air mixing than others.
Hence, Fairbanks, but not Anchorage, Duluth but not Dubuque, Tucson but not Tallahassee
Point source pollution: control the tailpipe…. How do we do this?
Cars, boat motors, motorcycles, trucks, lawnmowers, leafblowers…
emissions and acid rain.
Why does the east have such a problem with acid rain?
Good Ozone / Bad Ozone O3
CA is divided into air basins by the Air Resources Board (ARB)
Still an amazing number of days where CA is out of compliance
