Which Greenhouse Effect and Global Warming term is correctly associated with climate significance: “reduces the fraction of emissions remaining in the atmosphere”, and also with “a sink can weaken if ecosystems are degraded”?

Correct Answer: Option C — Carbon sink. Carbon sink is correct because it is reduces the fraction of emissions remaining in the atmosphere. Carbon sink is also associated with a sink can weaken if ecosystems are degraded. A further identifying fact is that Carbon sink is reduces the fraction of emissions remaining in the atmosphere. Another useful fact is that Carbon sink is associated with a sink can weaken if ecosystems are degraded. Why the other options are incorrect: Option A — Albedo: It is ice loss exposes darker surfaces that absorb more heat and is associated with the ice-albedo feedback can amplify warming. Option B — Paris Agreement: It is aims to strengthen the global response to climate change and is associated with countries submit nationally determined contributions. Option D — Carbon dioxide: It is the largest contributor to human-caused long-term warming and is associated with forests and oceans absorb part of its emissions. Exam Takeaway: Link Carbon sink with “reduces the fraction of emissions remaining in the atmosphere” and “a sink can weaken if ecosystems are degraded” for quick revision.
