Holocene winter rain and Sahara greening

By analyzing a sediment core from Lake Tislit, Morocco, researchers assembled a climate record of seasonal precipitation in Morocco over the past 18,500 years, and using vegetation model simulations, demonstrated that greenery in the Sahara expanded during the African Humid Period due to increased winter precipitation rather than due to a northward expansion of the monsoon; according to the authors, Sahara greenery was generated by a rainy season in winter in combination with intensified summer monsoons that did not reach the Mediterranean.
