Document Summary

1. 1 why studying natural hazards is important. 1. 2 magnitude and frequency of hazardous events. 1. 3 role of time in understanding hazards. 1. 5 fundamental concepts for understanding natural processes as hazards. 1. 6 many hazards provide a natural service function. Humans move 4 times as much as other natural processes. Millions of tonnes of coal production huge increase around 1900. Governments have to tell how much coal they mine. Coal mainly carbon ( c) burn it with oxygen (o2) produces carbon dioxide (co2) In 1950"s decided to directly measure co2 levels in the atmosphere. How does past e. s. e. (earth systems engineering) compare to future. 2 main differences: scale- in past, was more local, less global ii. Intent- in past, effects were unintended and unanticipated. Had more impact on the atmosphere than any other single organism in earth history". In 1921, midgley invented leaded gasoline (tetra-ethyl lead)
