Alarming water temperatures: Is there a new underwater heat wave ahead?

Alarming water temperatures: Is there a new underwater heat wave ahead?

With increasing water temperatures, the coastal region is increasingly facing challenges that are important for both the navy life and for the people who live and work there. Current reports by Maritima indicate that the sea surface temperatures during the summer concern can achieve what can be dangerous not only for the underwater world, but also for the bathers.

The developments in recent years have been alarming: As early as 2022, a temperature increase of over 5 ° C compared to the normal values ​​was found, especially in the maritime space around Marseille. This led to a longer phase of more than 70 days of a so -called marine Heatwave, which is directly related to extreme weather events such as the heavy storms in Corsica. According to bonpote , the frequency of these heat waves has doubled in the leadership of sea temperatures and could increase drastically by 2100 if no measures to reduce the greenhouse gas emissions are taken.

milieu and environmental concerns

climate change forces us to think about the health of our oceans. The increasing temperatures have documented serious effects on marine biodiversity, such as the Circularplace . Marine living beings are not only threatened by temperature changes, but also by phenomena such as the acidification of the oceans, which is caused by increased CO2 emissions. These changes concern the ability of organisms such as mussels and corals to form their shells and structures. At the same time, food security is put in danger, since important fish species have to differ due to their changed habitats.

Marie Bravo-Monin, the director of the marin park on the Côte Bleue, comments concerned about the possible repetition of the events of 2022, where Gorgons in the national park were badly damaged. "If the water temperatures are too high, the entire marine flora and fauna suffers," she says. The current calculations show that the water temperature is already critical during the start of the summer.

health effects on humans and animals

But not only the underwater world is on the brink. A too high water temperature can also be dangerous for humans. For the swimmers, the sea not only becomes uncomfortably warm, but could also favor the development of algae flowers that are poisonous and can have harmful effects on health. The concern for the quality of the water has therefore become more important.

Bonpote names the Malaïgue in 2018 to ensure that numerous mussels and oysters die in areas such as the Étang de Thau. This not only had economic effects on fishing, but also pose a danger to food safety.

The considerations are clear: to protect the maritime ecosystems and also make future generations dependent on the fish and other sea resources, urgently need to be traded. Measures such as the creation of effective protected areas and the efforts to combat climate change are in the foreground. This is the only way to ensure that not only the underwater world survives, but also the people who are dependent on it.
