Eutrophication will increase methane emissions from lakes and impoundments during the 21st century

摘要: Lakes and impoundments are an important source of methane (CH4), a potent greenhouse gas, to the atmosphere. A recent analysis shows aquatic productivity (i.e., eutrophication) is driver CH4 emissions from lentic waters. Considering that will increase over next century due climate change growing human population, concomitant in may occur. We simulate eutrophication waters under scenarios future nutrient loading inland show enhanced lakes substantially these systems (+30–90%) century. This increased emission has atmospheric impact 1.7–2.6 Pg C-CO2-eq y−1, which equivalent 18–33% annual CO2 burning fossil fuels. Thus, it not only limit preserve fragile water supplies, but also avoid acceleration change. .Agricultural intensification population likely century.  Here, authors this (+ 30–90%),
