Sea Levels are Rising at an Accelerating Speed

Sea levels are rising at an accelerating speed all around the world due to the ongoing melting ice sheets in Greenland and Antarctica.


According to a new satellite research, melting ice sheets in Greenland and Antarctica are speeding up sea level rise.

Looking at the current rate of melting, sea levels could rise by half an inch a year by the end of the century, says research published Monday in the Proceedings of the National Academy of Sciences. Such a level rise could leave world’s coastal cities’ portions underwater.

Satellite shows that sea levels are rising because of the warming of the ocean and melting from glaciers and ice sheets. Scientists used 25 years of satellite data to evaluate the Earth’s seas’ levels. Their calculations confirm scientists’ computer simulations and predictions from the United Nations that releases climate change reports regularly.

Sea level rise has two factors: the first one is year-to-year small rises and the second is falls and long-term rising. The causes behind the first factor are natural events and man-made climate change for another rising.

“The goal of this kind of research is not just to measure climate change but to figure out why it’s changing,” he said. “If you understand why it’s changing then you understand better what’s going to happen in the future,” said Steve Nerem, a University of Colorado, Boulder aerospace engineering professor and fellow at the Cooperative Institute for Research in Environmental Sciences.

Nerem also said that as the time has long passed we need to address this issue in the future fight against global warming.
