At its peak 6,000 years ago, a lake in the Sahara covered roughly 360,000 square kilometres, more than all five Great Lakes combined, yet what remains today, covers well under one per cent of that area

Let’s start with the number that stops you: roughly 360,000 square kilometres of lake surface in the middle of what is now the southern Sahara. That is a single lake larger than all five North American Great Lakes put together. And it sat where the map now shows some of the driest land on the planet.
The ghost of that lake still has a name. Lake Chad, shared by Chad, Niger, Nigeria and Cameroon, occupies the surviving southern part of the basin of the ancient giant geologists call Palaeola
