Record Heat at 500 Meters Depth: Mallorca Faces an Invisible Danger

Answer

Why is the sea around Mallorca getting warmer even far below the surface?

Scientists monitoring Mallorca’s waters have found that warming is not limited to the surface. At around 500 meters depth, temperatures have shown a strong upward trend, which is worrying because deep water stores heat for longer and changes more slowly. That can affect currents, marine habitats and the wider coastal ecosystem.
