What is Global Warming?  Global warming refers to the increase in temperature around the world over the last half of the twentieth century.  Class: Can you identify a pattern?

The Greenhouse Effect  The Greenhouse Effect is the process by which certain gases ( water vapour, carbon dioxide, methane and chlorofluorocarbons (CFC’s) ), allow the sun’s short wave radiation to heat up the earth, and trap an ever increasing amount of long- wave radiation from the earth.

The Enhanced Greenhouse Effect  Is the increasing amount of greenhouse gases in the atmosphere as a result of human activities.  Great Video Link! Great Video Link!

Carbon Sources and Sinks SOURCES SINKS  A carbon source is anything that releases more carbon than it absorbs  A carbon sink is anything than absorbs more carbon than it releases carbon sources- carbon sinks= ??? The Carbon Budget

Carbon Sources Natural Carbon Sources Human Induced Carbon Sources  Volcanic eruptions  Wildfires  Organic combustion/ decomposition  Burning of fossil fuels  Deforestation  Reduction in wetlands

Carbon Sinks Natural Carbon Sinks What are humans doing to each of these sinks to change their ability to absorb carbon? Why?  Plants/ Forests  Oceans  Wetlands

Carbon Dioxide Trends Historical Data (approx.) ppm ppm ppm ppm ppm
