Question 2

Identify three greenhouse gases and briefly explain how these gases are contributing to global warming.

Accepted Answer

Although carbon dioxide is the major greenhouse gas, trace gases such as methane, surface ozone, nitrous oxide, and CFCs also contribute to global warming. These gases absorb infrared radiation in the atmosphere, and this absorption slows the flow of heat into space, thus warming the lower atmosphere.
