英文摘要	The transition from a humid green Sahara to today's hyperarid conditions in northern Africa similar to 5.5 thousand years ago shows the dramatic environmental change to which human societies were exposed and had to adapt to. In this work, we show that in the 620,000-year environmental record from the Chew Bahir basin in the southern Ethiopian Rift, with its decadal resolution, this one thousand year long transition is particularly well documented, along with 20-80 year long droughts, recurring every similar to 160 years, as possible early warnings. Together with events of extreme wetness at the end of the transition, these droughts form a pronounced climate flickering, which can be simulated in climate models and is also present in earlier climate transitions in the Chew Bahir environmental record, indicating that transitions with flickering are characteristic of this region.
