Question

Which of the two following is the correct sequence of greenhouse gases according to their relative global warming potential in increasing order?

This question was previously asked in
UGC NET 2019 Paper 1 Question Paper (5-Dec-2019) (Shift 2)
The correct answer is

Carbon dioxide, Methane, Nitrous oxide, Chlorofluorocarbons

The concept of Global Warming Potential (GWP) measures how much heat a greenhouse gas traps in the atmosphere over a specific time period, compared to carbon dioxide. Let's evaluate the given greenhouse gases and arrange them in increasing order of their GWP.

  1. Carbon Dioxide (CO₂): This is the baseline reference with a GWP of 1. It serves as a standard against which the GWP of other gases is measured.
  2. Methane (CH₄): Methane has a higher GWP than CO₂, estimated to be approximately 25 times greater over a 100-year period, according to the Intergovernmental Panel on Climate Change (IPCC).
  3. Nitrous Oxide (N₂O): With a GWP about 298 times that of carbon dioxide, nitrous oxide is more potent than Methane in terms of its global warming contribution.
  4. Chlorofluorocarbons (CFCs): CFCs have the highest GWP of the gases listed, with values ranging from a few thousand up to 14,800, depending on the specific type of CFC, making them extremely potent greenhouse gases.

Thus, the correct sequence of these gases according to their relative global warming potential in increasing order is:

  1. Carbon dioxide
  2. Methane
  3. Nitrous oxide
  4. Chlorofluorocarbons

This matches the given option: Carbon dioxide, Methane, Nitrous oxide, Chlorofluorocarbons.
