Rifts in the Rift?

Big changes are occurring in East Africa's Rift Valley (https://www.theguardian.com/environment/2020/dec/13/rising-waters-threaten-kenya-wildlife-aoe). Its chain of lakes appear to be particularly influenced. The most northern of these, Lake Turkana, was some 6 m deeper in November 2020 than is usually the case at that time of the year. Satellite imaging also suggests that 2 more southerly lakes (Baringo and Bogaria), are in the process of fusing. They were 20 km apart in 2013 but this had been reduced to 13 kim by 2020. This flooding has led to problems in Kenya's national parks, with marooned giraffe's having to be ferried to safety and human populations moved from their current locations. Especially striking, is the reduction in the size of the lake's flamingo colonies, from 1.5 million to only 100,000 birds. Climate change and Africa?
