Scenario CO₂ Is Not the Only Greenhouse Gas (GHG)that Impacts Global

Multiple Choice

Scenario
CO₂ is not the only greenhouse gas (GHG) that impacts global climate change. Other GHGs may be equally or more effective than CO₂ at trapping heat on Earth. Climate scientists determine how much a GHG may impact global warming based on two factors: the efficiency with which a GHG absorbs energy (i.e., traps heat on Earth) and the length of time (in years) that the gas remains in the atmosphere. A unit of measurement called the Global Warming Potential (GWP) is used to describe how much energy a GHG absorbs over a specific period of time (100 years is a standard time frame) . All GWP values of GHGs are compared to the GWP of CO₂, which is given a value of 1.
-Chlorofluorocarbons (CFCs) are greenhouse gases that, for a specific amount of mass, trap significantly more heat than CO₂. How can you classify CFCs?

A) gases with lower GWP values than CO₂
B) gases with equal GWP values to CO₂
C) gases with greater GWP values than CO₂
