According to scientists from the US Aeronautics Agency (NASA), many cities may be engulfed by seawater in the next 100-200 years.
Many cities may be submerged by rising sea levels
NASA said, the latest satellite data indicates that the sea level will rise by at least one meter within the next 100-200 years. The ice sheets in Greenland and Antarctica are melting fast, the ocean warms and expands at a faster rate than before.

Professor Michael Freilich, director of NASA's Earth Sciences division, said that rising sea levels could completely submerge some island nations in the Pacific region . The low-lying states of the US such as Florida and some of the world's largest cities like Tokyo are in danger of disappearing.
NASA's predictions are based on results from a series of altitudes measuring sea level from the air. NASA and the CNES French Aviation Agency began launching sea level satellites in 1992.
" Very sensitive measuring devices. If mounted on a civil plane at 1,200 m altitude, they can detect the edge of a coin lying on the ground ," Professor Freilich said.
According to NASA, since 1992, oceans in the world have risen an average of 7.6 cm, some areas have a 23 cm rise. The cause of this phenomenon is due to ice melt . Greenland ice sheets melt with a volume of 303 billion tons per year over the past decade. Similarly, Antarctica also lost an average of 118 billion tons of ice per year.
