The graph shows how much sea levels changed from about 1870 to 2018. Items with pluses (+) are factors that caused ice to melt and sea levels to increase globally, while minuses (−) are variables that caused sea levels to decrease. These items are displayed at the time they were affecting sea level.
Which factor led to a decrease in sea levels?

Global dam projects
Thermal expansion
Melting mountain glaciers
Melting Antarctic ice sheets
