What is sea level rise?
Sea levels are rising due to two major causes: thermal expansion of the ocean (water expands as it warms) and the melting of land-based glaciers and ice sheets. As the atmosphere warms from increased atmospheric heat due to greenhouse gas emissions, the oceans absorb about 90 percent of the associated heat.

What NASA says on our warming climate
There are many local factors that determine if a specific location will have more or less sea level rise than the global average. Some local factors that determine community-level sea level rise are:
- Vertical land movement
- Regional ocean currents
- Variations in land height
- Whether the land is still rebounding from the weight of the ice age glaciers
Below are links to localized sea level predictions that take into account all of these local factors.
