Sea levels will rise drastically and change the climate says the NASA study. It says that the seas level rise twice as high by 2100 as estimated by NASA.

The rise in sea level may increase up to 65 cm in coming 80 years; this may cause serious problems to the people and climate near the coastal regions according to the detailed journal Proceedings of National Academy of Science.

“This is almost certainly a conservative estimate,” said Steve Nerem, Professor at the University of Colorado-Boulder. He is the one who led the team of NASA Sea Level Change which has conducted this study regarding the rise in sea level.

“Our extrapolation assumes that sea level continues to change in the future as it has over the last 25 years. Given the large changes we are seeing in the ice sheets today, that is not likely,” Nerem said in a statement.

“First, warmer water expands, and this “thermal expansion” of the ocean has contributed about half of the seven centimetres of global mean sea level rise that has been observed over the past 25 years,” Nerem said.

Secondly the water from melting ice flows into the ocean and increase the sea level around the world, this is the situation that will lead to the rise in sea level.

“The rate of sea level rise has risen from about 2.5 millimeters per year in the 1990s to about 3.4 millimeters per year today,” the researchers said.

The speed of the acceleration will be changed by geological events such as volcanic eruptions or climate patterns etc.
