Abstract: The aim of this literature study was to review the effects that climate change has on the intensification of eutrophication in lakes, specifically in a temperate climate. Furthermore, the latest research on the connection between greenhouse gas emissions and eutrophication in lakes was reviewed to explore the synergistic relationship between the two processes. In summary, the results were that the increase in temperature and precipitation associated with climate change can intensify eutrophication by increasing internal loading, algal blooms in lakes and transport of nutrients to the lake from its catchment area. Several studies conclude that this effect will be more prominent in temperate or boreal lakes. The latest research on greenhouse gas emissions connection to eutrophication was divided depending on which gas was studied. CO2 showed variation from sink to source between seasons and lakes, but some were shown to be net sources. CH4 emissions however had a strong connection to eutrophication, specifically algae blooms. N2O emissions had the weakest link to eutrophication, with several studies showing no correlation parameters linked with eutrophication and N2O emissions. However, some studies did find that more eutrophic lakes did release more N2O. It was concluded that there was a clear link between eutrophication and climate change and that the two processes reinforce one another.
