Final answer:
The difference in albedo between cleared and agricultural land becomes more pronounced when surface reflectivity changes, such as when the Arctic ice caps melt and expose dark water. This is because light-colored surfaces like snow and ice reflect more radiation than darker surfaces.
Step-by-step explanation:
The difference in albedo between cleared and agricultural land is particularly pronounced when surface reflectivity changes , such as when Arctic ice caps melt and expose dark water. Light-colored surfaces like snow and ice reflect more radiation than darker surfaces, so when the ice melts, more radiation is absorbed at the surface, which worsens global climate change.
