Autor: Nicholas A. O’Mara, Charlotte Skonieczny, David McGee, Gisela Winckler, Aloys J.-M. Bory, Louisa I. Bradtmiller, Bruno Malaizé, Pratigya J. Polissar

Publikováno v: Nature Communications, Vol 13, Iss 1, Pp 1-11 (2022)

Plant-wax isotope and dust flux records reveal that the long-term variability of the Northwest African monsoon is controlled by tropical solar radiation gradients. Grasslands expand into the Sahara during strong monsoons, but the ultimate composition

Publikováno v: Nature Communications, Vol 8, Iss 1, Pp 1-11 (2017)

The synchrony, spatial distribution and causes of the African Humid Period termination at 5.5 ka remain debated. Here, the authors show that rapid aridification in Cameroon and the central Sahel-Sahara took place between 5.8–4.8 ka and was likely t

Air masses loaded with mineral dust and originating from the Sahara arrive frequently in Europe, which has multiple impacts on global and regional cycles. However, the occurrence of these processes may further accelerate in the future in response to

International audience; Mineral dust deposition characteristics are poorly constrained, even in the Northeastern Tropical Atlantic Ocean, which is immediately downwind of the Saharan desert and the largest marine repository of aeolian dust in the wor

Pleistocene drivers of Northwest African hydroclimate and vegetation

Publikováno v: Nature communications. 13(1)

Savanna ecosystems were the landscapes for human evolution and are vital to modern Sub-Saharan African food security, yet the fundamental drivers of climate and ecology in these ecosystems remain unclear. Here we generate plant-wax isotope and dust f

Hydroclimate and atmospheric circulation over North Africa through the last two climatic cycles reconstructed from dust deposited off West Africa

On glacial to interglacial time scales, northern Africa fluctuated between arid to hyperarid states and much wetter conditions called African Humid Periods (AHP). These AHP are characterized by a major transformation of the Saharan hydrological cycle

International audience; The Mid-Pleistocene transition (MPT; 1200 to 800 thousand years, kyr) is marked by the shift from 41-kyr to 100-kyr interglacial-glacial cyclicity without substantial change in the astronomical forcing. This change in climate
