Sea level is expected to rise about 0.4 m (1.3 ft) by 2100 (the blue line in the figure above). However, the prediction is uncertain; different models suggest that we can expect anywhere from 0.2 m (green line) to 0.6 m (red line). Which, if any, of these increases should we prepare for? Explain your choice.
