Integrated approach for estimating climate change impacts on CO sink capacity of inland waterbodies using hydrodynamic modelling and GIS analysis.

As one of their key regulatory ecosystem functions, inland lakes serve as CO sinks. The CO sink capacity of inland lakes depends on their water temperature and salinity as well as their water volume which are all highly sensitive to climate conditions. This paper aims to quantitatively estimate the change in the CO sink capacity of Wadi El-Rayan Lakes under climate change scenarios.
