Fatal warning of marine heatwaves in the Balearics

In 2022, there were five marine heat waves between July and December. In August, the highest average surface temperature was recorded - 29.2C. In the case of one buoy, off the island of Dragonera, a temperature of 33.3C was registered; this was another record.

The Fundació Marilles, which is dedicated to marine conservation in the Balearics, has highlighted the potentially serious consequences that increases of this nature can have for marine ecosystems as well as for the economy and human living conditions. Rising sea temperatures are also a cause of the rise in sea level. It has been calculated that this will rise by between 55 and 77 centimetres by the end of the century and by up to 129 centimetres in 2150, which would result in the loss of beaches of between seven and fifty metres.
