A warming global climate will decrease Greenland's albedo due to melting ice and snow that are replaced by darker surfaces. This results in less sunlight being reflected and more heat being absorbed, contributing to further climate change. Therefore, the correct answer is that Greenland's albedo will go down.

A warming global climate will decrease Greenland's albedo as melting ice and snow are replaced by darker surfaces that absorb more sunlight. This change contributes to further climate warming, creating a feedback loop. Thus, the correct answer is that Greenland's albedo will go down. ;
