BIOL 1055 Lecture Notes - Lecture 24: Indoor Air Quality, 1995 Chicago Heat Wave, 2003 European Heat Wave
Document Summary
Models: based on well-established physical principles, use data from research. Positive feedback: phenomenon in which effect of a change (or an event), furthers the change, causing even more change. Negative feedback: phenomenon in which the effect of a change, diminishes the change. Albedo: reflectivity of a material to solar radiation. Ocean levels: estimated to rise 6 to 1" over the next century. Projected temperature predicted to raise 1-7 degrees celsius by the end of this century. Warming will occur more: on land in winter at poles. Non-renewable: coal, crude oil, natural gas, petroleum, nuclear power. Coal: most abundant fossil fuel, formed when plant matter is compressed to form dense, solid carbon structures. Greater the pressure, the greater the energy content. Consequences: air pollution, exposes people to txins, people die from coal mining. Natural gas biogenic formation: anaerobic bacterial decomposition of organic matter.
