The National Aeronautics and Space Administration (NASA) and its partners studied some satellite measurements and found that seas around the globe have risen about three inches on average for the last 23 years. They found that in some areas, ocean levels have climbed over nine inches.

According to scientists at the United States space agency, the global seas will continue to rise as warming temperatures are continuously melting ice sheets of Antarctica and Greenland. The satellite measurements warned that if world’s temperatures continue to rise, ocean levels will rise by about three feet by the end of the century.

The scientists warned that oceans will continue to rise in future, and their motive is to find out how fast and by how much they will rise. Joshua Willis, an oceanographer at NASA's Jet Propulsion Laboratory in La Cañada Flintridge, no one can stop seas from rising, and people should prepare themselves to face the situation when it will happen.

While talking about from where the additional water in seas coming from, Steve Nerem, a scientist at the University of Colorado, said about 33% of the rising sea level is because world’s oceans are expanding; one-third of the rising sea level is due to melting glaciers, and the rest is because of melting ice of Greenland and Antarctica.

“During the last decade, Greenland's ice sheet lost about 303 gigatons of ice on average each year, while Antarctica's ice sheet lost about 118 gigatons annually on average. One gigaton is a billion metric tons”, Nerem said.
