Out of Africa: An alternative scenario for the first human dispersal in Eurasia
Mètode Science Studies Journal: Annual Review, 2018 Recent paleoanthropological evidence from the early Pleistocene site of Dmanisi in Georgia has revealed that the first hominins out of Africa were more archaic than the coeval African and Asian Homo erectus.

Observed Linkages Between Marine Heatwaves and Extreme Weather Over Land: A New Zealand Case Study
International Journal of Climatology, EarlyView.Marine heatwaves consistently warm New Zealand's land surface, but rainfall impacts occur only when synoptic systems enable moisture transport. This 38‐year analysis shows MHWs act as thermodynamic background drivers of heat and conditional amplifiers of extreme rainfall events or droughts.

Replication and reinsertion of stalagmites sampled for paleoclimatic purposes
International Journal of Speleology, 2018 Sampling stalagmites for paleoclimatic study can enter into conflict with preserving the beauty and integrity of caves. To minimize this impact, a variety of sampling strategies have been used by researches aware of cave-conservation issues. Based on our

Subseasonal Predictability of Weekly Rainfall and Rainy Season Onset Over East Africa
International Journal of Climatology, EarlyView.This study evaluates the subseasonal predictability of weekly rainfall and rainy season onset over East Africa using the ECMWF extended range forecast model. Results show strong skill in forecasting weekly rainfall up to 4 weeks ahead, with higher accuracy during the March–May ‘long rains’ season.

Sources and fates of silicon in the ocean: the role of diatoms in the climate and glacial cycles
Scientia Marina, 2001 Diatoms with their fast growth rates and obligate requirement for Si have a unique relationship to the oceanic Si cycle with the potential for controlling the nutrient and CO2 environment of large important areas of the ocean.

Climatology and Trends of Sub‐Daily Precipitation Extremes in Croatia
International Journal of Climatology, EarlyView.Sub‐daily extreme precipitation indices reveal pronounced spatial variability, with the highest intensities and frequencies across the Adriatic region and the highlands. Seasonal and diurnal patterns highlight distinct regional behaviour, including summer maxima over the continental interior and nocturnal or early‐morning peaks along the Adriatic coast.

South Atlantic Multi‐Site Calibration of Coral Oxygen Isotope Paleothermometer
Geochemistry, Geophysics, GeosystemsCoral‐based stable oxygen isotopes (δ18O) have been used as a proxy for sea surface temperature (SST) since the 1970s, and δ18O–SST calibration studies have been fundamental to assure robust and faithful SST reconstructions.

New Holocene pollen records from the Brazilian Caatinga
Anais da Academia Brasileira de CiênciasWe present two pollen diagrams from the semi-arid Caatinga of the Catimbau National Park, in Pernambuco and from a Mauritia palm forest in the Caatinga/Cerrado ecotone of southern Piauí, NE Brazil, spanning the last 10,000 cal.

Changing Water Resources in the Indus Basin: A Multi‐Model Budyko‐Based Analysis
International Journal of Climatology, EarlyView.Budyko‐based analysis evaluates historical (1962–2005) and future hydroclimatic change across the Indus River Basin. Budyko shifts indicate rising atmospheric evaporative demand and increasing energy limitation under future scenarios. ABSTRACT Assessing hydroclimatic variability and future water availability is crucial for sustainable water‐resource ...
