Figure 23.20 Global warming and melting ice. In both (a) Antarctica and (b) Greenland, the amount of ice has steadily declined from 2002 to 2010. Data are plotted relative to the mean ice mass throughout the entire time period. (c) Measurements of sea level from 1993 to 2013 demonstrate a continual increase in sea level compared to the sea level in 1993.
