Climate variability during the present interglacial, the Holocene, has been rather smooth in comparison with the last glacial. Nevertheless, there were some rather abrupt climate changes. One of these changes, the desertification of the Saharan and Arabian region some 4–6 thousand years ago, was presumably quite important for human society. It could have been the stimulus leading to the foundation of civilizations along the Nile, Euphrat and Tigris rivers. Here we argue that Saharan and Arabian… 
Remote Vegetation Feedbacks and the Mid-Holocene Green Sahara
AbstractIn the mid-Holocene, the climate of northern Africa was characterized by wetter conditions than present, as evidenced by higher paleolake levels and pollen assemblages of savannah vegetation
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.
Holocene climate instability during the termination of the African Humid Period
The termination of the Holocene African Humid Period (∼9 to ∼6 kyr BP) is simulated with a three‐dimensional global coupled climate model that resolves synoptic variability associated with weather
The impact of Sahara desertification on Arctic cooling during the Holocene
Abstract. Since the start of the Holocene, temperatures in the Arctic have steadily declined. This has been accredited to the orbitally forced decrease in summer insolation reconstructed over the
Green Sahara tipping points in transient climate model simulations of the Holocene
The ‘Greening’ and subsequent desertification of the Sahara during the early to mid-Holocene is a dramatic example of natural climate change. We analyse a suite of simulations with a newly
Simulation of the Holocene climate evolution in Northern Africa : The termination of the African Humid Period
The Holocene climate evolution in Northern Africa is studied in a 9000-yr-long transient simulation with a coupled atmosphere– ocean–vegetation model forced by changes in insolation and atmospheric
On the cause of abrupt vegetation collapse in North Africa during the Holocene: Climate variability vs. vegetation feedback
The abrupt desertification over the northern Africa in the mid‐Holocene is studied in both a complex and a simple coupled climate‐vegetation model. In contrast to the previous mechanism that relies
Stability of the vegetation-atmosphere system in the early Eocene climate
So far, the transitivity of the global system has been analysed for late Quaternary (glacial, interClariy aim glacial and present-day) climate. Here, we extend this analysis to a warm, almost
Mid- to Late Holocene climate change: an overview


The greening of the Sahara during the mid-Holocene: results of an interactive atmosphere-biome model
An asynchronously coupled atmospherebiome model was used to assess the biogeophysical interaction during the mid-Holocene, 6000 years before present. The model determines its own land surface
The influence of vegetation-atmosphere-ocean interaction on climate during the mid-holocene
The model results indicate strong synergistic effects of changes in vegetation cover, ocean temperature, and sea ice at boreal latitudes, but in the subtropics, the atmosphere-vegetation feedback is most important.
Possible role of atmosphere-biosphere interactions in triggering the last glaciation
We coupled a global biome model iteratively with an atmospheric general circulation model to study the possible role of vegetation in the climate system, at the time of glacial inception 115,000
Modeling bio-geophysical feedback in the African and Indian monsoon region
Abstract. An asynchronously coupled global atmosphere-biome model is used to assess the dynamics of deserts and drought in the Sahel, Saudi-Arabia and the Indian subcontinent. Under present-day
Mid‐Holocene land‐surface conditions in northern Africa and the Arabian Peninsula: A data set for the analysis of biogeophysical feedbacks in the climate system
Large changes in the extent of northern subtropical arid regions during the Holocene are attributed to orbitally forced variations in monsoon strength and have been implicated in the regulation of
Feedbacks between climate and boreal forests during the Holocene epoch
PREVIOUS studies1–5 have demonstrated that the predictions of global climate models are highly sensitive to large changes in vegetation cover, such as the complete removal of tropical or boreal
Quantifying the role of biosphere-atmosphere feedbacks in climate change: coupled model simulations for 6000 years BP and comparison with palaeodata for northern Eurasia and northern Africa
Abstract. The LMD AGCM was iteratively coupled to the global BIOME1 model in order to explore the role of vegetation-climate interactions in response to mid-Holocene (6000 y BP) orbital forcing. The
Modelling global terrestrial vegetation–climate interaction
It is found that under present–day conditions of the Earth's orbital parameters and sea–surface temperatures, two stable equilibria of vegetation patterns are possible: one corresponding to present-day sparse vegetation in the Sahel, the second solution yielding savannah which extends far into the south–western part of the Sahara.
Mise en évidence de variations climatiques holocènes rapides, en phase dans les déserts actuels de Chine et du Nord de l'Afrique
The analysis of 718 Holocene dates from lake deposits (present-day Sahara) and palaeosols (arid zones in China), testifies to in-phase climatic variations in both regions: two optimal periods during
On multiple solutions of the atmosphere–vegetation system in present‐day climate
North Africa is probably the region on Earth which is most sensitive considering bifurcations of the atmosphere‐vegetation system at the global scale, according to an asynchronously coupled global atmosphere‐biome model.
