Which of the following gases is a major contributor to global warming?

✅Explanation:
Carbon dioxide (CO₂) is the major greenhouse gas responsible for global warming. It contributes to the greenhouse effect by trapping heat in the Earth's atmosphere, preventing it from escaping into space. This leads to an increase in Earth's average temperature, contributing to climate change.
-Carbon dioxide is released primarily through the burning of fossil fuels (coal, oil, natural gas), deforestation, and other human activities.

📌📌Other Options:
 (b) Carbon monoxide: While carbon monoxide is a harmful air pollutant. It can affect air quality and health.
 (c) Sulfur dioxide: Sulfur dioxide is a major pollutant associated with acid rain and air pollution. It can influence climate in other ways, such as by reflecting sunlight and potentially having a cooling effect.
 (d) Nitrous oxide: Nitrous oxide (N₂O) is a potent greenhouse gas. It does contribute to global warming, especially due to agricultural activities and industrial processes.

🔑Key Points:
-Carbon Dioxide is the gas, which is more responsible for global warming.
-Various factors like Concentration in atmosphere, Heat absorption and Lifetime of the gas decide the contribution of a gas to global warming.
-Of all the Greenhouse gases, CO2 has the highest concentration and also has a high heat absorption capacity.
-So all climate change policies and discussions are around reduction of CO2 and reducing carbon footprint.
-The other gases like CO(Carbon monoxide) indirectly contribute to global warming by altering the amount of other Greenhouse gases.

🛑Aditional Information:
-Global warming refers to the heating of earth’s atmosphere beyond desirable levels.
-The imbalance in the composition of gases in the atmosphere, which has relatively more capacity to absorb heat radiation, is the main cause for global warming.
-The gases contributing to global warming are called Greenhouse gases.
-The major Greenhouse gases are Carbon dioxide(CO2), Methane(CH4), Nitrous Oxide(N2O) and Water vapour.
-Other gases like Fluorinated gases (like HFC, CFC, ) also contribute to global warming.
