Increased Global Temperatures Are Linked to Melting Arctic Sea Ice

Increased global temperatures are linked to melting Arctic sea ice.By what process can melting Arctic sea ice increase global temperatures further,creating a positive feedback loop?

A) Melting sea ice adds freshwater to the Arctic, which is warmer than salt water.
B) Sea ice reflects solar energy, more of which will be absorbed if sea ice cover decreases.
C) Melting sea ice raises sea level, covering more of the land surface with absorbent water.
D) Melting sea ice adds water vapour to the atmosphere, increasing the greenhouse effect.
E) Thinner sea ice does not insulate the seawater from the atmosphere as well as thicker sea ice.
