  1. An Examination of Global Warming Existing and Expected Evidence in and around Washington Judy Thompson Meteorology August 14, 2010

  2. What is Global Warming? • Global warming is the unusually rapid increase in Earth’s average surface temperature over the past century primarily due to the greenhouse gases released by people burning fossil fuels. • Link to Explanation of Global Warning

  3. Definitions • Greenhouse gases -- Those gases, such as water vapor, carbon dioxide, nitrous oxide, methane, hydrofluorocarbons (HFCs), perfluorocarbons (PFCs) and sulfur hexafluoride, that are transparent to solar (short-wave) radiation but opaque to long-wave (infrared) radiation, thus preventing long-wave radiant energy from leaving Earth's atmosphere. The net effect is a trapping of absorbed radiation and a tendency to warm the planet's surface (McCracken).

  6. Raising Surface Air Temperature • It was my intent to show a histogram for temperatures in Clark Country going back at least 100 years. I was not able to find this data.

  11. Sea Level Trends for Seattle Washington

  12. Evidence of Global Warning in Washington State • According to the Washington State Department of Ecology’s web site “….more than 50 glaciers have disappeared from the Cascade Mountains, sea levels are changing along Washington’s coastlines and snowpack totals are expected to decline by 40 percent by 2040. “
