Lakes are changing worldwide: Human activities to blame

Worldwide, lake temperatures are rising and seasonal ice cover is shorter and thiner. This effects lake ecosystems, drinking water supply and fishing. International research now shows that these global changes in lake temperature and ice cover are not due to natural climate variability. They can only be explained by massive greenhouse gas emissions since the Industrial Revolution. To demonstrate this, the team has developed multiple computer simulations with models of lakes on a global scale, on which they ran a series of climate models. The researchers found clear similarities between the observed changes in lakes and model simulations of lakes in a climate influenced by greenhouse gas emissions. Besides measuring the historical impact of climate change, the team also analyzed various future climate scenarios.
