Warming Lakes: Climate Change Threatens the Ecological Stability of Lake Tanganyika

Tropical lakes in East Africa don’t grab headlines the way polar bears do, but climate change is having an effect on them, too. Although the changes are not as visible as melting polar ice caps, they are no less real. As in many lakes around the world, water temperature is on the rise in Lake…
