20th-Century warming in Lake Tanganyika is unprecedented

Lake Tanganyika's surface waters are currently warmer than at any time in the previous 1,500 years, a University of Arizona researcher and his colleagues report online in Nature Geoscience.

The rise in temperature during the 20th century is driving a decline in the productivity of the lake, which hosts the second-largest inland fishery in Africa.

"People throughout south-central Africa depend on the fish from Lake Tanganyika as a crucial source of protein," said study co-author Andrew S. Cohen, a UA professor of geosciences. "This resource is likely threatened by the lake's unprecedented warming since the late 19th century and the associated loss of lake productivity."

1. Since Lake Tanganyika lies in the Great Rift System,

has anybody considered whether it is warming due to surface conditions or from something happening from below (volcanism?)

2. It has been awhile since I read an article

looking at just that, there have been little in the way of tremblors or out-gassing that would indicate that it was warming by vulcanism.
