Global Warming The Greenhouse Effect Carbon Sources and Sinks QUICK NOTE: FOUND AN AMAZING, SIMPLE, PRESENTATION ON GLOBAL WARMING AND COULD NOT KEEP AWAY FROM SHARING. THIS SHOULD YOU WHEN WRITING YOUR ESSAYS Love, Ms. Renteria
2
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?
3
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.
4
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!
5
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
6
Carbon Sources Natural Carbon Sources Human Induced Carbon Sources Volcanic eruptions Wildfires Organic combustion/ decomposition Burning of fossil fuels Deforestation Reduction in wetlands
7
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.) 1870- 290 ppm 1900- 295 ppm 1930- 300 ppm 1980- 340 ppm 2013- 395 ppm
