How Iowa lost inches to sea level rise
Iowa lost nearly a foot of elevation to sea-level rise between 1970 and 2016, according to new research by the University of Iowa.
Researchers found that the state lost about 6 inches of elevation during that time.
The study, which was published online by the American Geophysical Union, found that about 2,600 acres (600 hectares) of land in Iowa was lost between 1970 to 2016.
It’s unclear how much of the loss is caused by human activities and how much by natural events.
In some places, like the Des Moines area, the study found that people were actively contributing to the sea level.
Iowa lost about 4 inches (11 centimeters) of elevation in that time period, according the researchers.
The area around Des Moines has had a steady rise in sea level since the 1940s.
Iowa lost about 1.8 feet (0.8 meters) of ground between 1970-2016, the researchers said.
This includes land, water, hills and fields.
Iowa’s losses could be more significant if it doesn’t address the threat of sea-levels rising, according with the study.
