Sediment core reveals 10,800 years of precipitation history in the Sahara

The analysis of a sediment core from an oasis lake in Chad provides new insights into the history of precipitation in the Sahara. The study, led by the University of Cologne, shows that a prolonged wet phase, which lasted from 14,800 to 5,500 years ago, was interrupted by short-term droughts. Such drought events could also occur in a similar manner in the future.
