Lake Geneva is facing a hidden crisis as its water temperature rises at an alarming rate, much faster than the world’s oceans. The average annual temperature of the lake has reached a record high of 13.6 degrees Celsius, causing a disruption in its delicate ecosystem.
Professional fishermen are experiencing the impact of global warming firsthand, with some fish species becoming more abundant or reproducing at different times, while others are disappearing as the waters warm. Despite a sizable catch, fishermen like Eric Jaquier are concerned about the long-term effects of climate change on the lake.
Scientists are also worried about Lake Geneva’s ecosystem, as crucial processes like ‘winter mixing’ have stalled. This process, where oxygen-rich surface water mixes with deep water, is essential for oxygenation and biodiversity in the lake. However, the lake has not experienced this mixing for over a decade, leading to concerns about the health of the ecosystem.
Experts like Marie-Elodie Perga from the University of Lausanne emphasize the importance of monitoring the lake closely and taking action to control CO2 emissions to prevent a catastrophic state. The video accompanying the article highlights the rising temperatures in Lake Geneva and the potential implications for its ecosystem.
Overall, Lake Geneva is facing a urgent situation as climate change continues to impact its delicate balance. Scientists, fishermen, and environmentalists are all expressing concerns about the future of the lake and the need for immediate action to mitigate the effects of global warming.
