The effects of climate change are concentrated on the Mediterranean coasts. HE sea level Increasing three times faster than expected in the Mediterranean “and will endanger human activities and infrastructure by the end of the century,” according to a recently published report by the Italian National Institute of Geophysics and Volcanology (INGV). Scientists warn gradual subsidence of large areas of land Coming from the coast, this also aggravates the problem.
In the report, in which Radboud University (Netherlands) also collaborated, it is stated that the current estimates for sea level rise published by the Intergovernmental Panel on Climate Change (IPCC) in 2021 are as follows:underestimated along the shore.”
Ground collapse aggravates the situation
“Subsidence, that is, the slow downward movement of the ground “Due to natural or anthropogenic causes, it plays an important role in the acceleration of coastal sea level rise triggered by global warming since 1880,” explains INGV researcher Marco Anzidei in a note published by the organism in question.
“Our analysis shows that Sea level is rising almost three times faster in some parts of the Mediterranean due to subsidence adds Antonio Vecchio, researcher at Radboud Universiteit Nijmegen and first author of the study.
In light of this evidence, the team of researchers recalculated IPCC projections out to 2150. 265 zones of the Mediterranean also correspond to 51 tide gauges of international networks Surveillance, including data on sinking in analyses. Sampled destinations include Catalonia, the Valencian Community, the regions of Murcia, Almería and Andalusia, as well as the Balearic Islands.
“The results show maximum and minimum differences ranging from approximately 109 centimeters more and 77 centimeters less respectively, according to the IPCC report, with the average value approximately 8 centimeters higher,” explains Vecchio.
According to these data, it is explained that “approximately 38,500 km2 of the Mediterranean coast (about 19,000 km2 of which is only in the northern part of the basin) will disappear in the near future.” will be more exposed to the risk of sea flooding“This will result in greater impacts on the environment, human activities and infrastructure.”
“Large parts of the coasts of Italy, Greece, Spain and France are sinking, thus accelerating sea level rise,” the study adds.
“Then, Concrete measures need to be taken to support coastal populationsThe report states that they will become increasingly vulnerable to sea level rise and the increasing risks associated with it later this century and beyond.
