Mediterranean heatwave sparks concern for marine life

A recent heatwave in the Mediterranean Sea has been so severe that scientists are concerned for marine life.

The human-induced climate crisis is making marine heatwaves more intense and prolonged, with sea surface temperatures off the coast of Mallorca since late June frequently exceeding 30C (86F).

Portugal’s maritime authority said the southern Algarve had experienced a marine heatwave between 28 June and 9 July. Temperatures have been significantly higher than the average observed over the past 20 years – with some areas 5C above normal.

This most recent marine heatwave has been the western Mediterranean’s most extreme for this time of year. While sea surface temperatures above 30C are not that unusual later in the summer, such conditions are unprecedented in late June.

The impact on marine wildlife and ecosystems from marine heatwaves can be significant. Prolonged exposure can drain the energy from sea creatures to a point where they can no longer survive. There is also evidence that some species go into survival mode and will not reproduce.
