Ocean level is rising day by day claims NASA, predicted to be highly dangerous and warned that the rise in the sea level could cause worst conditions, described by the climate models.

According to the latest satellite calculations from NASA and its partner scientists claim that, the level has risen nearly three inches since 1992. Some area even has risen to nine inches due to natural variation.

One third of the rise in the sea level caused by expansion of warmer ocean water, one-third by the ice loss from Greenland, Antarctica ice-sheets and remaining from melting mountain glaciers, estimates scientists.

"Given what we know now about how the ocean expands as it warms and how ice sheets and glaciers are adding water to the seas, it's pretty certain we are locked into at least three feet of sea level rise, and probably more," explained Steve Nerem from the University of Colorado, Boulder.
Sea level does not rise uniformly all over the world. Scientists observed that the sea level has been fallen over the past 20 years in US. Natural cycles have hid the impact of global warming.

Claiming that this pattern in US could change Josh Willis, oceanographer at NASA's Jet Propulsion Laboratory (JPL) in Pasadena, California said, "Sea level along the west coast of the United States has actually fallen over the past 20 years because of the long term natural cycles which is hiding the impact of global warming.”

According to the satellite measurement, Alaska shed an average of 303 gigatons and Antarctica ice-sheet has lost 118 gigatons which is larger than US and India’s glaciers.

The melting of glaciers is not proportional and may rise or fall in the coming decades.
