A new study published in the Proceedings of the National Academy of Sciences describes how rising water temperatures are causing a decline in Lake Tanganyika’s fish populations. Unfortunately, the full text of the study is behind a paywall. A synopsis of the study can be found on Voice of America and BBC News.

Sediment core samples have shown that in the last 150 years Lake Tanganyika’s water temperatures have been rising. This steady increase in water temperatures, not commercial fishing, has had the largest impact on fish populations in the lake. Rising water temperatures, particularly at the surface, have led to a drop in oxygen levels at all depths of the lake. For more information on the study check out the links above.
