Seawater 4 degrees warmer than normal

That would be the result of the heat we had last week.

The seawater temperature of the Mediterranean Sea has also risen due to the heat wave in southern Europe. This in itself has no consequences for marine life, but according to VLIZ, heat waves will follow each other more frequently and the warming of the seawater will lead to a lack of oxygen. And that can have serious consequences in the long run.
