Answer 1

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

Methane is significantly more powerful in trapping heat compared to carbon dioxide, with a global warming potential (GWP) that can be over 25 times greater over a 100-year period. Nitrous oxide is also a potent greenhouse gas, having a GWP of about 298 times that of carbon dioxide over the same timeframe. Therefore, both gases have a considerably greater impact on global warming than carbon dioxide.
