Unformatted text preview: A map of the Antarctic Peninsula with the location of the the Wilkins Ice Sheet, which is on the southern portion. Ice bridge broke April 5, 2009. Ice Shelf is size of Connecticut. The End of Life as WE Know It? Data Source: C.D. Keeling and T.P. Whorf, Atmospheric CO2 Concentrations (ppmv) derived from in situ air samples collected at Mauna Loa Observatory, Hawaii, Scripps Institute of Oceanography, August 1998. A. Neftel et al, Historical CO2 Record from the Siple Station Ice Core, Physics Institute, University of Bern, Switzerland, September 1994. See http://cdiac.esd.ornl.gov/trends/co2/contents.htm Atmospheric carbon dioxide (CO2) concentrations (1750 to present) 270 280 290 300 310 320 330 340 350 360 370 1750 1800 1850 1900 1950 2000 parts per million volume Mauna Loa (1958-present) Siple Station (1750-) Antarctica Note Interannual Variation 03/01/11 Global warming enhanced by emissions of man-made gases 1 2 3 4 5 6 Net addition 7 Net Loss to Atm. pH decline Carbonic Acid Other Greenhouse Gasses Methane Nitrous Oxide Ozone CFCs Plus smaller Carbon Dioxide (CO2) : Carbon dioxide enters the atmosphere through the burning of fossil fuels (oil, natural gas, and coal), solid waste, trees and wood products, and also as a result of other chemical reactions (e.g., manufacture of cement ). Methane (CH4) : Methane is emitted during the production and transport of coal, natural gas, and oil. Methane emissions also result from livestock and other agricultural practices and by the decay of organic waste in municipal solid waste landfills. Nitrous Oxide (N2O) : Nitrous oxide is emitted during agricultural and industrial activities, as well as during combustion of fossil fuels and solid waste. AND Bacteria Fluorinated Gases : Hydrofluorocarbons , perfluorocarbons, and sulfur hexafluoride are synthetic, powerful greenhouse gases that are emitted from a variety of industrial processes....
