CONTENT PREVIEW

Methane is a powerful greenhouse gas that plays a major role in climate change. Like carbon dioxide, methane traps heat in Earth's atmosphere. However, each methane molecule traps far more heat than a carbon dioxide molecule. Scientists estimate that methane traps about 28 times more heat over a 100-year period. This makes methane particularly important when studying global warming.

Methane comes from several human activities that connect our food, energy, and waste systems. Livestock farming produces large amounts of methane when cattle and other animals digest their food. Rice farming also releases methane because flooded rice paddies create conditions where bacteria produce this gas. The energy system contributes methane through leaks in oil and gas drilling operations and pipelines. Natural gas is mostly methane, so even small leaks release this potent gas directly into the air. Landfills represent another major source because organic waste rotting without oxygen produces methane.

Evidence shows that methane has one important characteristic that makes it different from carbon dioxide. Methane breaks down in the atmosphere much faster, lasting about 12 years compared to centuries for carbon dioxide. This shorter atmospheric lifetime means that cutting methane emissions can slow warming relatively quickly. Fixing a leaky natural gas pipeline or capturing gas from a landfill produces climate benefits within years rather than decades.

Scientists observe that methane reduction offers practical solutions across multiple systems. For example, California now requires large dairy farms to capture methane from animal waste and use it for energy. Some landfills install collection systems that gather methane and burn it for electricity instead of releasing it. Oil and gas companies can use infrared cameras to detect pipeline leaks and repair them. These actions demonstrate how addressing methane connects to everyday choices about food production, energy use, and waste management.

Understanding methane matters because it represents one of the fastest levers we have to slow climate change. While reducing carbon dioxide remains essential for long-term climate stability, cutting methane emissions can produce measurable cooling effects within our lifetimes. The challenge involves making changes across agriculture, energy infrastructure, and waste systems simultaneously.

Interesting Fact: A single cow can produce between 150 and 265 pounds of methane per year through digestion. With over 1 billion cattle worldwide, livestock farming accounts for roughly 32% of all human-caused methane emissions.

According to the passage, how much more heat does methane trap compared to carbon dioxide over 100 years?

About 12 times more heatAbout 28 times more heatAbout 100 times more heatThe same amount of heat

Which of the following is NOT mentioned as a major source of human-caused methane emissions?

Livestock farmingCoal-burning power plantsOil and gas pipeline leaksLandfills

What does the term 'atmospheric lifetime' mean in the context of greenhouse gases?

The age of the atmosphereHow long a gas stays in the atmosphere before breaking downThe temperature of the atmosphereHow high a gas can rise in the atmosphere

Based on the passage, what is the atmospheric lifetime of methane?

About 12 monthsAbout 12 yearsAbout 28 yearsSeveral centuries

Why does the passage suggest that reducing methane emissions can produce faster climate benefits than reducing carbon dioxide?

Methane is easier to capture than carbon dioxideMethane breaks down much faster in the atmosphereThere is less methane than carbon dioxide in the atmosphereMethane comes from fewer sources than carbon dioxide

What technology do oil and gas companies use to detect pipeline leaks?

X-ray camerasUltraviolet sensorsInfrared camerasRadar systems

According to the passage, how do rice paddies produce methane?

Rice plants naturally release methane as they growFlooded conditions allow bacteria to produce methaneFertilizers used on rice break down into methaneHarvesting equipment leaks methane into the fields

What example does the passage give of a practical methane reduction solution in California?

Banning cattle farmingRequiring dairy farms to capture methane from animal wasteClosing all landfillsStopping all natural gas production
