The average surface temperature of the Mediterranean Sea has risen by more than one degree Celsius in just 25 years. Last year, temperatures reached their highest value since measurements began.
This is evident from measurements carried out by the Italian research institutes ENEA and INGV in the Ligurian and Tyrrhenian Seas on the Genoa – Palermo route.
Water warmer, even in deep ocean layers
In addition to the increase in average surface temperature, the ‘thermal snapshot’ of the Mediterranean Sea, taken over 100 campaigns with more than 3,000 probes, also shows an increase in the deeper layers of the ocean.
Moreover, the analysis of the measurements shows that warming was above 0.4 degrees between 2013 and 2016, followed by a slight decrease and a stationary phase in subsequent years and again a gradual increase from 2021 to September 2023, when these are maximum reached. .
“The set of temperature data along the same stretch of ocean is crucial for climate studies because it allows to assess evolution over time. This allows you to see whether there is warming or cooling over time in the monitored area,” the ENEA researchers said in a press release.
Models point to further increases
“The available models indicate a possible further increase in water temperature. We will continue to measure sea temperatures to determine whether these predictions come true,” emphasizes Simona Simoncelli, researcher at the INGV Institute.
