New molecular proxies of temperature and hydrology are helping to constrain tropical climate change and elucidate possible forcing mechanisms during the Holocene. Here, we examine a similar to 14,000… Expand
The termination of the African Humid Period (AHP) about 5 thousand years ago (ka) was the most dramatic climate shift in northern and equatorial Africa since the end of the Pleistocene. Based on… Expand
 The largest abrupt climatic reversal of the Holocene interglacial, the cooling event 8.6-8.2 thousand years ago (ka), was probably caused by catastrophic release of glacial Lake Agassiz-Ojibway,… Expand
This corrects the article DOI: 10.1038/nature09839
Abstract Lithologic, CHIRP (Compressed High Intensity Radar Pulse) sonar, paleomagnetic, stable isotopic and micropaleontological analyses of sediment cores from Lake Champlain (New York, Vermont)… Expand
Abstract The climate of tropical Africa transitioned from an interval of pronounced, orbitally-paced megadroughts to more humid and stable conditions approximately 70,000 years ago (Scholz et al.,… Expand

This model provides a mechanistic basis of the often-observed 2H-enrichment from the expected fractionation values in studies of broadleaf angiosperm leaf-wax δ2H, and allows the isolation of the precipitation dynamics of individual periods of the growing season. Expand
The temperature history of the Malawi basin, at least for the past 500,000 years, strongly resembles past changes in atmospheric carbon dioxide and terrigenous dust flux in the tropical Pacific Ocean, but not in global ice volume. Expand
Abstract New biomarker analyses from Lake Albert, East Africa spanning ~ 15–9 ka show the most extreme, abrupt, multi-stage climate and environmental shifts during the last deglacial transition of… Expand
Using molecular palaeotemperature proxies to reconstruct the mean annual temperature in mid-Pleistocene lacustrine sediment from the Valles Caldera, New Mexico, it is found that the driest conditions occurred during the warmest phases of interglacials, when the MAT was comparable to or higher than the modern MAT.
