International Journal of Climatology, EarlyView.Drought spatiotemporal propagation and direct driving variables are assessed at multiple time steps with high spatial resolution using various drought indices (SPI, SPEI and SPDI) and entropy based mutual information under an ensemble of climate change projections over Tunisia. ABSTRACT Projecting drought occurrence and spatiotemporal propagation under

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.

Sunshine Duration in Brazil From Meteosat (1983–2020): Climatology, Variability and Long‐Term Trends
International Journal of Climatology, EarlyView.Using nearly four decades of Meteosat satellite data (1983–2020), this study presents a country‐wide climatology of sunshine duration (SDU) in Brazil. The results reveal marked regional contrasts, dominant modes of variability, and significant long‐term trends, providing new information on the most relevant meteorological systems that influence SDU and

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

A Modeling Experiment on the Grounding of an Ice Shelf in the Central Arctic Ocean During MIS 6 [PDF]
, 2003 High-resolution chirp sonar subbottom profiles from the Lomonosov Ridge in the central Arctic Ocean, acquired from the Swedish icebreaker Oden in 1996, revealed large-scale erosion of the ridge crest down to depths of 1000 m below present sea level ...

Dry‐Season Water Deficits in the Southwestern Amazon Under High Emissions
International Journal of Climatology, EarlyView.Projected climatic water deficit in the study region indicates a longer and more intense dry season, with delays in the onset of the wet season under higher emission scenarios. These changes, particularly, pronounced under SSP5‐8.5, suggest increased ecological vulnerability and greater seasonal water stress.

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.

International Journal of Climatology, EarlyView.Athens' climate according to Thorthwaite is stable despite warming trends. Athens' climate remains semi‐arid and mesothermal over 165 years. Strong increases in evapotranspiration and stable precipitation were found. Soil water storage capacity affects water deficits but not aridity type.
