1. Which of these is true about the melting of sea ice?

Correct Answer: Correct answer is: (B) Ice has a higher albedo than the ocean's surface and so as ice melts, the ocean absorbs more heat.

Exam Relevance: AP Environmental Science, GRE Subject Test in Environmental Science, Climate Change Exams

Difficulty: Moderate

Concept notes: The albedo of a surface is a measure of how much light or radiation it reflects. Ice and snow have a high albedo, reflecting a significant portion of the sunlight that hits them. In contrast, the ocean's surface has a lower albedo and absorbs more sunlight, leading to warming.

Common Mistakes: A common misunderstanding is that the melting of sea ice directly cools the ocean by adding cold, fresh water, which is not the primary effect.

Explanations: Ice has a higher albedo than the ocean's surface, meaning it reflects more sunlight. As sea ice melts, the darker ocean surface is exposed, which absorbs more sunlight and heat. This leads to a positive feedback loop where the warming ocean causes more ice to melt, further increasing the absorption of heat.

Option Analysis:

Option A: This option is incorrect because the addition of cold, fresh water from melting ice does not significantly cool the vast ocean. The primary effect is the change in albedo.
Option B: This option is correct because the higher albedo of ice means it reflects more sunlight, and as it melts, the ocean absorbs more heat, leading to further warming.
Option C: This option is incorrect because while polar bears are affected by melting sea ice, this is not a direct consequence of the albedo effect.
Option D: This option is incorrect and dismisses the scientific consensus on climate change.

Mnemonic: Ice reflects, ocean absorbs.

2. Which of the following is a major contributor to climate change due to its greenhouse gas emissions?
