GGR202H5 Lecture Notes - Lecture 8: Thermal Pollution, Neritic Zone, Cool Air
Document Summary
Melting of sea ice, decreases albedo effect, more ice melts. Melting of permafrost, releases co2, increases temperature, increases more co2.

Advantage: identifies dangerous toxicants before they are released. Disadvantage: can slow down the pace of technological advance. What is one advantage that coal-fired power plants have over nuclear power: nuclear power is much safer. Habitat fragmentation/destruction and thermal pollution can kill fish. Prediction that u. s. oil production will peak at one point of time. What are two abatement/mitigation strategies that can be used to combat global climate change? (1) reduction of emissions of carbon dioxide gases and (2) carbon tax. What are two reasons why some critical air contaminants have been declining over time? (1) cleaner-burning vehicle and (2) improve federal policies. Thermal inversion: where a layer of cool air is trapped beneath warm air.
