- Above is a plot of changes in sea level predicted by the Hadley Centre model from the years 1860 to 2100, under a medium to high emissions scenario.
- The dotted blue line shows expected changes due to melting of the Greenland ice sheet;
- The green line predicts changes due to melting of glaciers and snow on land;
- The red line is the major component of sea level rise which is thermal expansion of ocean waters.
- Changes in the Antarctic ice sheet are difficult to estimate and are shown by the blue line.
- Adding these together gives an estimated sea level rise of about 0.4 metres from the middle of the last century to 2100, 0.1m of which should already have occurred, leaving around 0.3m over the next 100 years.
