What is Global Warming? Global warming is the unusually rapid increase in Earths average surface temperature over the past century primarily due to the greenhouse gases released by people burning fossil fuels.

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).

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.

Evidence of Raising Sea Levels in Washington State Extremely high tides on the Washington Coast line and the impact.

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