<h3>What happens if sea levels rise?</h3>
The main physical effects of sea level rise are beach erosion, inundation of deltas, flooding, and the loss of numerous marshes and wetlands. As a result of saltwater intrusion, increased salinity will probably become a concern in coastal aquifers and estuary systems.
<h3>How is sea level rise measured?</h3>
Tide stations and satellite laser altimeters are the main tools used to measure sea level. The height of the sea as measured along the shore in relation to a particular place on land is what tide stations all around the world tell us about what is happening locally.
<h3>How will sea level rise affect us in the future?</h3>
And as the oceans get larger due to a rising climate, more people may be at risk of coastal flooding by 2100, putting up to 410 million people at risk. The increase of coastal towns as a result of building and development also puts more people at risk.
