Document Summary
Video one fossil fuel production and consumption. Fossil fuels: uneven geographies of production and consumption. Primary driver of global climate change and the changing atmospheric chemistry. Kinds of fossil fuels, contributions, uneven availability of production and consumption. Combustible materials obtained from below ground (and formed from remains of organisms during the geological past), such as coal, petroleum and natural gas . From dead vegetation and plankton + pressure = fossil fuels. Responsible for 66% of historic carbon emissions since 1850. Responsible for 88% of carbon emissions since 2000. Greater proportion of our overall contributions to climate change. 1751 2012, 337 billion tonnes of carbon released into atmos. (half of that since mid 1970s) Land us cover change increasingly smaller portion of contribution. Burning known reserves would far exceed out carbon budget" (1400 gigatonnes) for maintaining a 2 degree rise in temp. If we burn all known reserves would far exceed a 2 degrees rise.
