Which compares the effectiveness of methane and nitrous oxide as a greenhouse gas with that of carbon dioxide?(1 point)

Question

Responses

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

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

Only 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.

Answer 1

Both methane and nitrous oxide are more effective greenhouse gases than carbon dioxide. Methane has a much higher global warming potential than carbon dioxide over a short time frame, and nitrous oxide is also significantly more effective at trapping heat in the atmosphere. Therefore, the correct response is:

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