Lakes in Switzerland are seeing unprecedented temperatures, exceeding 25°C due to a recent heatwave, with an average increase of 5°C over two weeks. The heat negatively affects fish species and aquatic flora struggling in these warm waters. Algae growth is fueled by the heat and sunlight, leading to oxygen depletion and harmful blue-green algae blooms that threaten water quality and health risks for humans and pets. Predictions suggest a cooling trend that may provide temporary relief to the aquatic ecosystem.
Lakes across Switzerland are experiencing record-high temperatures due to a heatwave, with some lakes exceeding 25°C. The increase negatively affects both fish and aquatic flora.
Warm water temperatures promote excess algae growth, which depletes oxygen levels in the water, endangering aquatic life and disrupting the natural ecosystem.
Toxic blue-green algae thrive in warmer conditions, affecting water quality and posing health risks to humans and pets, especially when visible as foul-smelling surface blooms.
