The graph above shows the average trend in sea levels over the last century. One-third of the sea level rise can be contributed to the thermal expansion of the ocean water as a result of increasing ocean temperatures. Other than the thermal expansion of ocean water, what is the other factor that has contributed to the two-thirds of the average sea level rise that we have seen over the last 100 plus years?
A) the melting of icebergs and other sea ice due to increases in temperatures
B) the melting of glaciers and other land ice as a result of increases in temperatures
C) the increase in precipitation rate due to the increases in temperature and change in global climate
D) the increased absorption of carbon dioxide as a result of large quantities of carbon dioxide emissions
