What could be the effects of global warming on coastal areas?

If sea levels should start to rise as the United Nations (through their working group called the IPCC) feels that it might, increased flooding of very low areas could start to occur. We have not yet experienced an increase sea level rise beyond what has been experienced for many decades. In fact this past year marked a very unusual event, sea level change was actually negative against all model projections. This, dovetailed with the fact that sea level change has been slowing means this is not a current or immediately imminent projection based on actual data.

A:As global warming continues, the oceans are beginning to warm. Warm water expands in volume. That is the main reason for the present rise in sea levels. The second reason is the melting of glaciers and ice caps. So a rise in sea levels will flood coastal areas.
