3. Terminology
Greenhouse Gas Positive and Negative Feedback - Homeostasis Infrared Radiation Greenhouse Effect
Greenhouse Gas
Gas that absorbs infrared radiation
Positive Feedback
Change in some condition triggers a response that intensifies the changed condition
Infrared Radiation
Radiation that has a wavelength that is longer than that of visible light, but shorter than that of radio waves
Greenhouse Effect
Increase of heat in a system where energy enters (often as light), is absorbed as heat, and released sometime later

14. Factors Associated with Climate Change
Increased concentration of CO2 (right)
Burning fossil fuels in cars, industry and homes
Deforestation
Burning of forests
Increases in other greenhouse gasses

15. Radiative Forcing
Radiative Forcing (RF) is the measurement of the capacity of a gas or other forcing agents to affect that energy balance, thereby contributing to climate change. Put more simply, RF expresses the change in energy in the atmosphere due to GHG emissions.

16. Pollutants That Cool the Atmosphere
Atmospheric Aerosols
Both human and natural sources
Tiny particles (or sulfur) that remain in troposphere for weeks or months
Sulfur-laden layer in the atmosphere reduces the amount of sunlight reaching earth
Complicates models of climate change
