  abstract = {{T}he climate history of the {S}ahara desert during recent millennia is obscured by the near absence of natural climate archives, hampering insight in the relative importance of southerly (tropical) and northerly (midlatitude) weather systems at submillennial time scales. {A} new lake sediment record from {O}unianga {S}erir oasis in northern {C}had, spanning the {L}ate {H}olocene without interruption, confirms that immediately before ca 4200 years ago, the {S}ahara experienced an episode of hyperaridity even more extreme than today's desert climate. {T}he hypersaline terminal lake which formed afterwards never desiccated during the late {H}olocene due to continuous inflow of fossil groundwater, yet its water balance was sensitive to temporal variation in local rainfall and lake surface evaporation. {O}ur in-lake geochemical proxies show that, during the last 3000 years, century-scale hydroclimate variation in the central {S}ahara primarily tracked the intensity of the tropical {W}est {A}frican monsoon, modulated at shorter time scales by weather patterns linked to shifts in midlatitude {A}tlantic {O}cean circulation.},
