Which Greenhouse Effect and Global Warming term is correctly associated with climate significance: “ice loss exposes darker surfaces that absorb more heat”, and also with “the ice-albedo feedback can amplify warming”?

Last Updated:

AParis Agreement
BCarbon dioxide
CAlbedo
DMethane
Correct Answer: AlbedoYour Answer: C

Explanation

Correct Answer: Option C — Albedo. Albedo is correct because it is ice loss exposes darker surfaces that absorb more heat. Albedo is also associated with the ice-albedo feedback can amplify warming. A further identifying fact is that Albedo is ice loss exposes darker surfaces that absorb more heat. Another useful fact is that Albedo is associated with the ice-albedo feedback can amplify warming. Why the other options are incorrect: Option A — Paris Agreement: It is aims to strengthen the global response to climate change and is associated with countries submit nationally determined contributions. Option B — 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. Option D — Methane: It is warms more strongly per molecule than carbon dioxide over shorter periods and is associated with it is the main component of natural gas. Exam Takeaway: Link Albedo with “ice loss exposes darker surfaces that absorb more heat” and “the ice-albedo feedback can amplify warming” for quick revision.

Important Notes

  • Albedo is the fraction of incoming radiation reflected by a surface.
  • It is associated with snow and ice generally have high albedo.
  • A key feature is that ice loss exposes darker surfaces that absorb more heat.
  • Another useful fact: the ice-albedo feedback can amplify warming.
  • Exam trap: Albedo should not be confused with Methane, which is warms more strongly per molecule than carbon dioxide over shorter periods.
