Sea level rise


New Size Estimates Define How Much Earth's Glaciers Could Raise Sea Level
The relatively small glaciers that drape the planet's mountains will play an important role in future sea level rise, according to a new study that estimated glaciers' collective size.

Researchers calculated the ice thickness for 171,000 glaciers worldwide, excluding the Greenland and Antarctic ice sheets, which hold the bulk of Earth's frozen water.


Through a combination of direct satellite observations and modeling, they determined the total volume of ice tied up in the glaciers is nearly 41,000 cubic miles (170,000 cubic kilometers), plus or minus 5,000 cubic miles (21,000 cubic km).


If all the glaciers were to melt, global sea levels would rise almost 17 inches (43 centimeters), the scientists found.
