In certain areas of the Mediterranean, sea levels are rising three times faster than estimates so far, over 38,500 square kilometres of coastline will soon be at risk of flooding.

This is shown by the study conducted by three Italian researchers from the Rome and Bologna offices of the National Institute of Geophysics and Volcanology and the Dutch University of Radboud, published in the journal Environmental Research Letters.

For Italy, the coasts most at risk are those of Friuli Venezia-Giulia, Veneto, Emilia-Romagna and the northern Pulia on the Adriatic side, along with those of Tuscany, Lacio and part of Sardinia on the Tirren side.

The cause of this increasing change in sea level rise predictions lies in the phenomenon of slipping.

"Reversal, that is, the slow movement of land due to natural or anthropogenic causes, has a crucial role in accelerating sea level rise along coastlines caused by global warming since 1880," notes Marco Anzidei, the studio engineer with Antonio Vecchio and Enrico Serpelloni.

"Our analyses show that, precisely because of the dip, in some areas of the Mediterranean sea level is rising almost three times faster than in stable areas," adds Vecchio from Radboud University and first author of the research.

In the research, Serpelloni explains, data from satellite navigation systems have been used, which allow the speed of vertical earth motion to be calculated extremely accurately. In light of this data, the three researchers recalculated current projections up to 2150 in 265 areas of the Mediterranean.

"In areas that are most at risk there will be greater impacts on the environment, human activities and infrastructure," anzidei says: "It is therefore necessary to take concrete action to support the coastal population."
