(top) Global map of 2017 sea level compared to the 1993–2017 average. Blue areas were above average, and brown areas were below average. (bottom) Monthly observations of sea level (black line) overlaid with the sea level calculated by adding together the primary inputs to sea level rise (purple line): added water, mostly from melting glaciers and ice sheets (blue line) and volume expansion due to warming (red line).
