Which outcome is directly amplified when decreased Arctic ice cover reduces the Earth's albedo?

💡 Explanation

When Arctic ice decreases, the albedo effect diminishes because less solar radiation is reflected back into space, leading to increased absorption of solar energy by land and ocean. Therefore permafrost thawing advances, rather than ocean acidification, circulation weakening, or ozone destabilization, which involve different mechanisms.
