For years scientists have been claiming that global warming and climate change are causing an increase in sea levels and now there is fresh satellite based evidence that sea levels are indeed increasing across the globe.
Scientists have published findings of their analysis of twenty-five years of satellite data proving that climate models have indeed been correct in predicting that sea levels will rise at an increasing rate. Researchers have shown in the study that since 1993, ocean waters have moved up the shore by almost 1 millimeter per decade on top of the 3 millimeter steady annual increase.
Researchers say that if we consider this acceleration sea levels will gain an additional millimeter per year for each of the coming decades with a probability that this increase could double up in future.
“The acceleration predicted by the models has now been detected directly from the observations. I think this is a game-changer as far as the climate change discussion goes,” said co-author Gary Mitchum, PhD, associate dean and professor at the University of South Florida College of Marine Science. “For example, the Tampa Bay area has been identified as one of 10 most vulnerable areas in the world to sea level rise and the increasing rate of rise is of great concern.”
Researchers used statistical analysis to enhance previous studies based on tide gauge data, which have also suggested acceleration over the last century. However, satellites give a better view of sea level rise, because samples are collected over the open ocean, rather than just along the coastline.
Experts have long said warming temperatures are heating ocean waters and melting ice sheets in Greenland and Antarctica. As it continues, the next generation will experience a far different landscape than it does today.
