Elevated carbon dioxide levels have been shown to contribute to the greenhouse effect,resulting in an increase in mean global temperature.Ecosystems where the largest warming has already occurred include snow-covered northern coniferous forests,tundra,and arctic sea ice habitats.Which statement best explains how the elimination of ice-covered ecosystems affects the rise or fall in global temperature?

Question

Ice-covered surfaces reflect more sunlight and heat back into the atmosphere, whereas darker, more absorptive surfaces such as water absorb more heat, contributing to the warming trend. As ice melts, more of these darker surfaces are exposed, exacerbating the greenhouse effect and leading to further increases in global temperature.
