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

question 34

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.
-In this scenario, how would you best describe CO₂?

• A)It is a baseline comparison for the GWP values of all other GHGs.
• B)It is a greenhouse gas whose GWP value is dependent upon the GWP values of all other GHGs.
• C)It is the greenhouse gas that is the most efficient at trapping heat on Earth.
• D)It is the greenhouse gas that is the least efficient at trapping heat on Earth.
