Study Notes

Understanding the Greenhouse Effect and Global Warming

The greenhouse effect is the normal trapping of the earth's heat in the lower atmosphere due to the conversion of light into heat as it strikes the earth's surface.
Greenhouse gases, including carbon dioxide, methane, water vapor, nitrous oxide, and CFCs, trap heat in the atmosphere, regulating temperature.
Concentration of carbon dioxide in the atmosphere has risen from 315 parts per million (ppm) in 1960 to 391 ppm in October of 2012, with pre-Industrial Revolution levels at 280 ppm.
The average global temperature has fluctuated over time, with evidence of ice ages and warming cycles.
Global warming can have natural causes such as volcanic activity and changes in the sun's intensity, as well as human causes like burning fossil fuels and waste decomposition.
The rise in concentration of greenhouse gases can lead to an enhanced greenhouse effect, magnifying the greenhouse effect.
Human causes of increased greenhouse gas concentrations include combustion of fossil fuels and increased animal waste production from livestock.
The increased level of carbon dioxide in the atmosphere may lead to continued warming, and it remains to be determined if the earth will enter a cooling cycle.
The concentration of carbon dioxide in the atmosphere has natural fluctuations, historically measured to be between 200 and 280 ppm.
The graph shows the relationship between carbon dioxide concentrations and earth temperatures, indicating natural causes for the cycling.
Human actions, such as burning fossil fuels for energy production and transportation, are the primary contributing factors to the increase in greenhouse gas concentrations.
The decomposition of trash also contributes to increased methane gas in the atmosphere, with human actions being the primary contributing factors.
