Sea temperatures off Mallorca drop temporarily — temporary reprieve or false alarm?

Answer

Why is Posidonia so important for Mallorca’s coastline?

Posidonia oceanica is a key seagrass for Mallorca’s coastal waters. It helps bind carbon, stabilizes the seabed and creates habitat for many species. If the sea stays too warm for too long, these meadows can weaken, which can also affect beach stability and fish nursery areas.
