I WONDER - What Is Methane?

Methane is over 25 times more effective than CO2 at trapping heat in the atmosphere, making it a significant short-term greenhouse gas. It originates from sources like landfills, natural gas systems, and livestock farming. Although methane remains in the atmosphere for only about 12 years, its high potency necessitates reducing emissions to mitigate climate change effectively.

How much more effective is methane compared to CO2 in trapping heat over a century?

• 25 times

• 100 times

• 10 times

• 50 times

Which of the following is NOT a source of methane emissions?

• Livestock farming

• Landfills

• Natural gas systems

• Solar panels

What is the approximate atmospheric lifespan of methane?

• 50 years

• 20 years

• 12 years

• 5 years

Why is reducing methane emissions important in the short term?

• Methane lasts longer than CO2 in the atmosphere

• Methane's high potency contributes significantly to climate change

• Methane emissions are easy to control

• Methane is less potent than CO2

Which of the following best describes methane's role in climate change?

• A long-term greenhouse gas

• A short-term but highly potent greenhouse gas

• A greenhouse gas with no significant impact

• A gas that only affects local climates
