Answer :

Final answer:

Methane is more potent than carbon dioxide regarding heat retention but has a shorter atmospheric lifespan. Methane emissions primarily arise from agricultural activities, while carbon dioxide emissions stem from fossil fuel combustion. Understanding the differences in their greenhouse effects helps address climate change effectively.


Explanation:

How Do Methane and Carbon Dioxide Differ in Their Greenhouse Effects?


Methane (CH₄) and carbon dioxide (CO₂) are both potent greenhouse gases, but they have different characteristics and impacts on climate change.


1. Potency and Timeframe


Methane is significantly more effective at trapping heat in the atmosphere than carbon dioxide, being about 25 times more potent over a 100-year period. However, methane has a much shorter atmospheric lifespan, persisting for about 12 years before it breaks down into carbon dioxide and water.


2. Sources and Emissions



  • Primary Sources of Methane: Methane is primarily released from agricultural practices (such as enteric fermentation in ruminants), landfills, and fossil fuel extraction. Its emissions occur during the digestion of food by livestock and the decomposition of organic waste.

  • Primary Sources of Carbon Dioxide: CO₂ is emitted during fossil fuel combustion, deforestation, and various industrial processes such as cement production. Its emissions contribute to a more prolonged increase in atmospheric CO₂ levels.


3. Climate Impact Duration


While the short-term impact of methane is profound due to its heat-trapping ability, the long-term effect of carbon dioxide is significant due to its persistence in the atmosphere. Thus, addressing methane emissions can help achieve short-term climate goals, while reducing CO₂ emissions is crucial for long-term climate stability.
