Tanganyika fish stocks damaged by climate change

 

Global warming has lead to a reduction in fish yields in East Africa's Lake Tanganyika, according to a new paper published in Nature.

Scientists from the University of Arizona have found that the water temperature in the lake has been rising over the past century, and that wind speeds have fallen. The combination of these factors has lead to a reduction in the nutrient flow in the lake, reducing the amount of primary productivity from photosynthetic algae at the base of the food chain.

Scientists now believe that global warming is a bigger problem for Tanganyika than human activities in and around the lake.
