In 30 years we have gained 173,000 square kilometers of mainland

Despite rising sea levels, around the planet Earth they have earned around 173,000 square kilometers of mainland, mostly thanks to human activity. And this whole process has taken place only in 30 years, from 1985 to the present.

This is what emerges from a recent study carried out by the Dutch institute Deltares published in the scientific journal Nature Climate Change.

Artificial constructions

To make the study, the researchers have developed an online tool that they have called 'Deltares Aqua Monitor', which allows any user to visualize the changes of surface water in any area of ​​the Earth, using the database used from Google Earth Engine and NASA satellite images, with a resolution of approximately 30 meters.

"We expected that the coast would be withdrawing as a result of rising sea levels, but it is surprising to see how they are growing in all parts of the world," he said. Fedor Baart, Deltares researcher.

Apparently, most of the new surface waters correspond to small lakes generated by the melting of glaciers in the Tibetan Plateau. On the other hand, the human being has dedicated to expanding 33,700 square kilometers of coastal areas, as well as the artificial creation of an island on the coast of Dubai, the modification of the coastline in China, the current size of the Aral Sea or the reduction of Lake Mead, in Nevada. Experts believe that more studies are still needed to see the impact that these global changes can have on our planet.
