Global warming is causing global mean sea level to rise in two ways. First,
glaciers and ice sheets worldwide are melting and adding water to the ocean
. … A third, much smaller contributor to sea level rise is a decline in the amount of liquid water on land—aquifers, lakes and reservoirs, rivers, soil moisture.
How does climate affect rising sea levels?
A warming climate can
cause seawater to expand and ice over land to melt
, both of which can cause a rise in sea level. … The second mechanism is the melting of ice over land, which then adds water to the ocean.
What are the 3 causes of sea level rise?
Ice melting from land into the ocean, warming waters that expand, a slowing Gulf Stream, and sinking land
all contribute to sea level rise. Although a global phenomenon, the amount and speed of sea level rise varies by location, even between the East and the West Coasts.

How do we know sea levels are rising?
To estimate how much of the observed sea level rise is due to thermal expansion, scientists
measure sea surface temperature using moored and drifting buoys, satellites, and water samples collected by ships
. Temperatures in the upper half of the ocean are measured by a global fleet of aquatic robots.

- Reduce your footprint.
- Protect wetlands. Wetlands act as natural.
