AbstractThe termination of the African Humid Period in northern Africa has been described as abrupt, occurring within centuries, as well as gradual, in response to incremental decreases in summer insolation. This study examined the rapidity of the change in diatom assemblages over the period from 6.5 to 4.5 cal ka BP, in a core studied previously at a coarser resolution. This transition was characterized by high variability of assemblages, which could be related, in part, to changes in water… 



Climate-Driven Ecosystem Succession in the Sahara: The Past 6000 Years

This gradual rather than abrupt termination of the African Humid Period in the eastern Sahara suggests a relatively weak biogeophysical feedback on climate.

Post-glacial arid episodes in Ethiopia have implications for climate prediction

Several lines of geomorphological and stratigraphical evidence suggest that the widespread early post-glacial wet phase in tropical Africa between 12,500 and 5,000 yr BP (refs 1, 2) was interrupted

Abrupt Shifts in Horn of Africa Hydroclimate Since the Last Glacial Maximum

Quick-Dry Region The Sahara Desert is one of the driest places on Earth. However, 11,000 to 5000 years ago, it was a relatively lush region containing savannah grasslands and humid tropical forests.

Regime Shifts in the Sahara and Sahel: Interactions between Ecological and Climatic Systems in Northern Africa

The Sahara and Sahel regions of northern Africa have complex environmental histories punctuated by sudden and dramatic “regime shifts” in climate and ecological conditions. Here we review the current

Groundwater-Mediated Response to Holocene Climatic Change Recorded by the Diatom Stratigraphy of an Ethiopian Crater Lake

The diatom stratigraphy of a 23-m sediment core from Lake Tilo, a maar lake in the Ethiopian Rift Valley, provides a 10,000-yr record of lake salinity and trophic status. Until 5500 14C yr B.P., the

Holocene climate less stable than previously thought

Until recently, Holocene climate was thought to be extremely stable with none of the abrupt variations that characterize the cold climates of glacial times [Dansgaard et al., 1993]. New terrestrial,

Climate has been relatively stable at high latitudes during the past 10,000 years, but as [Gasse][1] explains in her Perspective, the tropics have seen large hydrological shifts during this time. She
