Abstract Reconstructing rainfall variability and moisture sources is a critical aspect to understand past and future hydroclimate dynamics. Here, we use changes in the deuterium content of land-plant leaf waxes from two marine sediment cores located

Abstract Past East Asian Monsoon variability has been reconstructed using oxygen isotopes of cave speleothems as well as proxy indicators from Chinese loess sequences. However, where the speleothem record is dominated by precession cycles, loess magn

Abstract Fires in Africa account for more than half of global fire-carbon emissions but the long-term evolution of fire activity and its link to global climate change remains elusive. Paleofire records provide descriptive information about fire chang

Periodic meltwater pulses from the Laurentide-Greenland Ice Sheets during the last deglaciation drove abrupt changes in sea surface temperature and sea ice extent, according to sediment core biomarker proxy records from the Eirik Drift, eastern Labra

Leaf wax n-alkane biomarkers are widely used to infer past vegetation dynamics and hydroclimate changes. The use of these compounds strongly relies on the characterization of modern plants. However, few studies have explored leaf waxes of modern plan

Northern Africa’s past climate is characterized by a prolonged humid period known as the African Humid Period (AHP), giving origin to the “Green Sahara” and supporting human settlements into areas that are now desert. The spatial and temporal e

The distribution and isotopic composition (δ13C and δD) of lipids are proxies used to determinate paleoenvironmental conditions including precipitation regimes, vegetation changes and sources of organic matter, among others. This data article descr

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

Debate exists on the sign of change in tropical atmospheric circulation during global warming. Here the authors show a weaker Walker cell over the Indian Ocean during the warmer late Holocene compared to the globally colder Last Glacial Maximum, impl

It is well accepted that global circulation models equipped with stable water isotopologues help us better understand the relationships between atmospheric circulation changes and isotope records in paleoclimate archives. Still, isotope-enabled model
