The sustainability of the aquatic ecosystem throughout the world faces critical challenges due to the increase in anthropogenic and natural disturbances.

A study is published on Climate change induced eutrophication of cold-water lake in an ecologically fragile nature reserve in  Journal of Environmental Sciences on Climate change. The study shows that climate change has played an important role in the eutrophication of Lake Tianchi.

Lake Tianchi is a typical cold water lake and a UNESCO/MAB (Man and Biosphere) nature reserve located at high latitudes and at high altitudes with relatively low human activity, to examine the links between climate change and eutrophication.

As part of the UNESCO Biosphere Reserve and the Bogda Man, Lake Tianchi has been well preserved for the prevention of human intervention, but why has it been infected by eutrophication in recent years?

The increase in temperature, changes in precipitation patterns and hydrodynamic fluctuations induced by wind during the summer season have been suggested as an important contribution to accelerated eutrophication.

The results also showed that the local temperature and changes in precipitation were closely related to the large-scale atmospheric circulation, which opens the door to the method that will be applied in other regions without local climate information.

This study suggests that there is an urgent need to consider adaptation to climate change in the conservation and management of coldwater lakes around the world.
