The Intergovernmental Panel on Climate Change (IPCC) predicts increases in global average surface temperature from 1.1 to 6.4 °C
for the year 2100. Here, we focus on the impact of climate warming on eutrophic shallow lakes in the Netherlands, using three
representative lakes that cover the full range of lake sizes and depths. In these lakes, temperature has been shown to be the main
determinant of hatching and growth of young-of-the-year fish. Because records of water temperature of our study lakes are incomplete,
we applied an existingmodel to predictwater temperatures from air temperatures for shallow, wind exposed and holomictic water bodies.
To evaluate the implications of our results for marine systems, we also analyzed water temperature data of Marsdiep, a tidal inlet to the
Waddensea.
