✓ Lake ecosystems provide vital services for humanity, but, due to
global climate change, the quality and quantity of these services is
decreasing.
✓ Lakes supply us with clean water and fish, they regulate nutrient cycling
and modify climate change effects by controlling floods and the amount of
CO2, which is the main cause of climate warming. In an urbanizing world,
the aesthetic and recreational importance of lakes for human well-being is
increasing.
✓ Changes in temperature, precipitation and wind affect lake levels and water
availability, alter the distribution of oxygen and nutrients, and impact the
survival and abundance of aquatic organisms: algal blooms expand
causing massive fish kills.
✓ Understanding these mutual interactions through improved climate
models, monitoring of water quality, and assessing ecosystem health is
crucial for managing and mitigating the impacts of climate change on lakes.
✓ As the impact of eutrophication and climate change follow the same
pathways affecting nutrient availability and cascading effects in the food
web, establishing stricter control over anthropogenic nutrient loading
is the most efficient adaptive strategy to preserve the ecological integrity
of lakes and the services they provide.
