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
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!
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 SourcesHuman 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.)
1870- 290 ppm
