Global sea levels up 8 cm since 1992, says NASA

Sea levels worldwide rose an average of nearly 8 centimeters since 1992, the result of warming waters and melting ice, Reuters reported, citing a panel of NASA scientists.

They are rising faster than they did 50 years ago, and “it’s very likely to get worse in the future”, Nerem said Wednesday.

Some areas showed sea levels rising more than 25 cm, but they fell in other regions, such as along the US West Coast, an analysis of 23 years of satellite data showed.

Scientists believe ocean currents and natural cycles are temporarily offsetting a rise in sea levels in the Pacific, and the US West Coast could experience a significant rise in sea levels in the next 20 years.

Low-lying regions, such as Florida, are especially vulnerable, said Michael Freilich, director of NASA’s Earth Science Division.

”Even today, normal spring high tides cause street flooding in sections of Miami, something that didn’t happen regularly just a few decades ago,” Feilich said.

More than 150 million people, mostly in Asia, live within 1 meter of the sea, he said.
