Experts warn that this trend will continue in the coming years, according to data collected by a group of NASA scientists. The aforementioned increase in the level of the seas of the entire planet reaches an average of 7.62 cm above the levels of 1992 , although the values change depending on the geographical areas. In some cases, the sea has risen to 22 cm.
The main culprit for rising ocean and sea levels is global warming, largely caused by human activity. As a result of warming, glaciers and large masses of ice at the poles are melting, and the temperature of the water rises, causing it to expand. According to University of Colorado geophysicist Steve Nerem, "the situation is very likely to get worse in the future." So much so that, even if the necessary actions were taken to try to reverse the situation and change the trend, it would take centuries for the seas to return to the levels prior to climate change.
For NASA experts, the rise in sea level puts the future of many cities and coastal towns around the world at risk, and threatens to erase a multitude of islands from the map forever, with which in some cases , especially in the Pacific, entire countries would disappear.
