Which gas contributes to global warming through its greenhouse effect?
Detailed Explanation:
Carbon dioxide (CO₂), methane (CH₄), and nitrous oxide (N₂O) are all greenhouse gases (GHGs) that trap heat in the atmosphere and contribute to global warming.
CO₂ is the most abundant anthropogenic GHG from fossil fuel combustion; methane has 25 times higher global warming potential (GWP) than CO₂ over 100 years and is released from agriculture and landfills; nitrous oxide has 298 times higher GWP than CO₂ and is emitted from agricultural soils and industrial processes.
Therefore, more than one of the above gases contribute to the greenhouse effect and global warming.
