Sea level is rising at an alarming rate, say scientists

A new study has revealed that sea level rise is real and is accelerating at an alarming rate. The latest findings are roughly in agreement with the projections made by the Intergovernmental Panel on Climate Change (IPCC). The latest study predicted that the accelerating sea level rise will reach to 66 centimeters (26 inches) by the end of the century, that is, by 2100. For the study, the researchers looked at 25 years of satellite data and found that the sea level rise is not a hoax but it is actually happening and that to be at an alarming rate.

As per the report, the sea level has been rising at about three millimeters per year in the last 4-5 years and if this climate change issue goes on, then it is estimated that the sea level rise may increase to 10 millimeters per year by 2100. The study informed that the melting of glaciers in Greenland and Antarctic are the main drivers of sea level rise. Lead Author of the Study, Steve Nerem professor of aerospace engineering sciences at the University of Colorado in Boulder said, “This acceleration, driven mainly by accelerated melting in Antarctica and Greenland, has the potent to double the total sea level rise by 2100 as compared to projections that assume a constant rate — to more than 60 centimeters instead of about 30. He further said that their estimations are certainly conservative.

Co-author of the study, John Fasullo, a climate scientist at the National Center for Atmospheric Research said that their study highlights the important role that can be played by satellite records in validating climate model projections. According to Anny Cazavene, director of Earth Science at International Space Science Institute in France, the sea level rise can a better gauge of climate change in action as compared to rising temperature. The researchers of the latest study revealed that Climate change results in rising sea levels in two ways. One is thermal expansion, in which, increasing concentration of greenhouse gases in Earth’s atmosphere leads to increase in oceanic temperature which results in expansion of water. Second is the melting of ice at poles that adds more and more water to the seas.
