Question

Responses

Neither methane nor nitrous oxide is a more effective greenhouse gas than carbon dioxide.
Neither methane nor nitrous oxide is a more effective greenhouse gas than carbon dioxide.

Only methane is a more effective greenhouse gas than carbon dioxide.
Only methane is a more effective greenhouse gas than carbon dioxide.

Only nitrous oxide is a more effective greenhouse gas than carbon dioxide.
Only nitrous oxide is a more effective greenhouse gas than carbon dioxide.

Both methane and nitrous oxide are more effective greenhouse gases than carbon dioxide.

Answer 1

Both methane and nitrous oxide are more effective greenhouse gases than carbon dioxide. Methane has a global warming potential (GWP) that is significantly higher than that of carbon dioxide over a 20-year period, and nitrous oxide also has a higher GWP than carbon dioxide. Therefore, the correct response is:

Both methane and nitrous oxide are more effective greenhouse gases than carbon dioxide.
