An increase of approximately 1.5°C in the temperature of Greek seas over the past 30 years has been recorded by a study conducted by scientists from the METEO unit of the National Observatory of Athens.

However, this rise shows geographic variations. Specifically, in many areas, particularly in the Thracian Sea, the Central Ionian Sea, and sea regions south of Crete and Rhodes, the warming trend reaches and even exceeds 2°C within the past 30 years.

In contrast, areas in the Central and Southern Aegean show a much smaller warming trend.

The study, focused on trends in key climate parameters in Greece during 1991-2020, was published in the international journal Atmosphere.

The research examined trends in temperature, rainfall, and sea temperature over the past 30 years based on data from the European Copernicus service.
