The researchers have analysed satellite images and catchment data from over 1000 lakes worldwide (Eawag) . Of over a thousand lakes studied worldwide, about one in ten shows strange behaviour. In general, there is an increasing tendency for aquatic ecosystems to tip over. The ecological stability of lakes is decreasing, especially in regions with low GDP and large human populations. Lakes are considered precise indicators of climate change and other large-scale changes. Phenomena such as eutrophication and fundamental changes in lake species composition are accordingly well studied. But a global overview of how often such profound-hard to reverse-changes occur in the biological-physical system of a lake and which factors are responsible for them has been lacking until now.
