Document Summary
Species loss, ecosystem disruption and human health. Climate: rends in weather patterns over an extended period of time (years: up to decades. Climate system: interactive system of five compartments: atmosphere, land surface, hydrosphere, biosphere, cryosphere (snow and ice) Earth: the heat is reflected back on the earth and released to the atmosphere, most of the waves are absorbed by greenhouse gases. More human activities cause more carbon dioxide to be released: problem with methane: more potency. Diagram: shows increase release of carbon dioxide concentration through the years, methane and nitrogen gas are also increasing all cause the planet to become warm. Every time in history, when there was a peak in carbon dioxide, there was also a peak in temperature. Temperature is directly proportional to carbon dioxide. Fossil fuels (number one human activity is burning of fossil fuels: electrically generated by coal, 42, transportation (use of crude oil, 24, industrial process, 20, residential and commercial uses, 14%
