What are the 4 main 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.

Will the earth be underwater?

The simple answer is no. The whole world will never be underwater. But our coastlines would be very different. If all the ice covering Antarctica , Greenland, and in mountain glaciers around the world were to melt, sea level would rise about 70 meters (230 feet).

What happens if sea levels rise?

Consequences. When sea levels rise as rapidly as they have been, even a small increase can have devastating effects on coastal habitats farther inland, it can cause destructive erosion, wetland flooding, aquifer and agricultural soil contamination with salt, and lost habitat for fish, birds, and plants.

  • How does climate change affect sea levels?

    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. Second, the volume of the ocean is expanding as the water warms.

    How does climate change affect coastal areas?

    Climate change threatens coastal areas, which are already stressed by human activity, pollution, invasive species, and storms. Sea level rise could erode and inundate coastal ecosystems and eliminate wetlands. Warmer and more acidic oceans are likely to disrupt coastal and marine ecosystems.
