Methane, a greenhouse gas, is 80 times more potent than carbon dioxide in terms of its global warming capacity. Approximately 40% of methane emitted is from natural sources and about 60% comes from human-influenced sources, including livestock farming, rice agriculture, biomass burning and so forth.

Statement 1: Methane is more potent than carbon dioxide in terms of its global warming capacity.
Methane is indeed more potent than carbon dioxide when it comes to its global warming capacity. Methane has a higher global warming potential (GWP) than carbon dioxide over a 20-year time frame. This means that methane has a greater ability to trap heat in the atmosphere compared to carbon dioxide. According to the Intergovernmental Panel on Climate Change (IPCC), methane has a GWP of 28-36 times higher than carbon dioxide over a 100-year period. This makes it a significant contributor to climate change.
Statement 2: Majority of the methane emitted is from natural sources.
This statement is incorrect. While natural sources do contribute to methane emissions, the majority of methane emissions come from human activities. According to the Global Methane Initiative, approximately 60% of global methane emissions are attributed to human activities, such as fossil fuel production and use, livestock farming, rice agriculture, and waste management. These activities release significant amounts of methane into the atmosphere, contributing to the overall greenhouse gas emissions.
Statement 3: Livestock farming, rice agriculture, and biomass burning emit methane.
This statement is correct. Livestock farming, particularly enteric fermentation (digestive processes in ruminant animals) and manure management, is a significant source of methane emissions. Methane is produced during the digestive process of ruminant animals, such as cows and sheep, and is released through belching and flatulence. Manure management practices, such as storage and spreading, also release methane.
Rice agriculture is another major source of methane emissions. When rice is grown in flooded paddy fields, anaerobic conditions in the soil promote the production of methane by microorganisms. The methane is then released into the atmosphere.
Biomass burning, such as the burning of forests and agricultural residues, also emits methane. When organic materials burn incompletely, methane is produced as a byproduct and released into the atmosphere.
In conclusion, statement 1 is correct as methane is more potent than carbon dioxide in terms of its global warming capacity. Statement 2 is incorrect as the majority of methane emissions come from human activities. Statement 3 is correct as livestock farming, rice agriculture, and biomass burning are significant sources of methane emissions. Therefore, the correct answer is option B, which includes statements 1 and 3.

Statement 3 is correct as livestock farming, rice agriculture, and biomass burning are significant sources of methane emissions. Therefore, the correct answer is option B, which includes statements 1 and 3.
