Climate scientist Dr. Maria Torres argues that reducing methane emissions would slow global warming more quickly than reducing CO2 in the short term. Methane is a more potent greenhouse gas but breaks down faster in the atmosphere.
Which data would most effectively support Torres's argument about short-term impact?
CO2 is the most abundant greenhouse gas
Methane sources include agriculture and natural gas
Climate models show a 50% methane reduction would lower global temperature 0.3°C within 20 years, while equivalent CO2 cuts would take 100+ years to show similar effects
Both gases contribute to climate change
Correct Answer: C
Choice C is the best answer. Quantifies the timeline difference: 20 years vs 100+ years for similar effects.
- Context clues: Torres claims methane cuts work "more quickly" in "short term."
- Evidence evaluation: 20-year methane effect vs 100-year CO2 effect proves speed advantage.
- Verify: Climate model comparison directly tests the timeline claim.
💡 Strategy: "Faster" claims need comparative timeline data.
