NASA expresses worry and is now doing an “intensive research effort” to figure out the exact rate of the sea level as ice in the poles are melting. The melting of the poles results to an increase of the rise in ocean to 3.21 millimeters every year.
According to NASA, Greenland is melting faster now than of the other ice regions in the world. Although Antarctica covers more ice than Greenland, its melting rate is slower though. However, Greenland is loosing several gigantons of ice per year.
It is said that when all ice of Greenland melts, it can raise the sea level to 20 feet. But when all ice in Antarctica melts, it raises the ocean level to 200 feet.
