SL & HL Questions on Environmental Impact: Global Warming 1. The table below lists the current tropospheric concentration and global warming potential for some common greenhouse gases: Greenhouse gas Formula Concentration GWP Carbon dioxide CO2 388500 1 Methane CH4 1870 25 Nitrous oxide N2O 323 298 CFC-12 CCl2F2 534 10900 Sulfur hexafluoride SF6 0.007 22800 Current tropospheric concentration is measured in parts per billion (ppb). Global Warming Potential (GWP) indicates the warming effect of a greenhouse gas relative to carbon dioxide over a period of 100 years. Source: Blasing: TJ and K Smith 2011. Recent Greenhouse Gas Concentrations in Trends: Compendium of Data on Global Change. Carbon Dioxide Information Analysis Centre, Oak Ridge National Laboratory, US Department of Energy, Oak Ridge, TN, USA. (a) State one other gas found in the atmosphere that also contributes to global warming: (b) In 1750, the tropospheric concentrations of carbon dioxide and methane were 280000 and 700 ppb respectively. Explain why both have increased significantly since then. (c) Explain why the tropospheric concentrations of CFC-12 and sulfur hexafluoride were both zero ppb in 1750. (d) Suggest why there are restrictions on the manufacture and use of sulfur hexafluoride even though its overall contribution to global warming is estimated to be less than 0.2%.
