Extended Chronology of Drought in South Central, Southeastern, and West Texas

open access: yesTexas Water Journal, 2011
Short instrumental climatic records prevent appropriate statistical and historical characterization of extreme events such as the extent, duration, and severity of multiyear droughts.

Anomalously cool clumped isotope temperatures in tropical lagoon carbonates

open access: yesThe Depositional Record
Carbonate clumped isotopes are a powerful tool for paleoclimate reconstruction due to the ability to reconstruct past changes in both temperature and precipitation‐evaporation balance.

Implications of Liebig’s law of the minimum for tree-ring reconstructions of climate

open access: yesEnvironmental Research Letters, 2017
A basic principle of ecology, known as Liebig’s Law of the Minimum, is that plant growth reflects the strongest limiting environmental factor. This principle implies that a limiting environmental factor can be inferred from historical growth and, in ...

Station‐Based Assessment of Sub‐Seasonal Climate Trends in the Tyrolean Alps (Austria)

open access: yesInternational Journal of Climatology, EarlyView.
In this study, we quantify the magnitude and significance of sub‐seasonal trends in the Tyrolean Alps (Austria) by collecting, processing and analysing meteorological observations from a dense network of climate stations. Our analysis indicates a warming rate of 0.43°C/dec over 1964–2023, greater sub‐seasonal trend variability when the analysis window ...

Reconstruction of Late Pleistocene Paleoenvironments Using Bulk Geochemistry of Paleosols from the Lake Victoria Region

open access: yesFrontiers in Earth Science, 2017
The impact of changing environments on the evolution and dispersal of Homo sapiens is highly debated, but few data are available from equatorial Africa. Lake Victoria is the largest freshwater lake in the tropics and is currently a biogeographic barrier ...

Machine Learning‐Based Correction of Reanalysis Surface Radiation Fluxes Using Ground‐Measured Data in the Southern Brazilian Pampa Biome

open access: yesInternational Journal of Climatology, EarlyView.
This study demonstrates that ERA5 provides more accurate surface radiation flux estimates than MERRA2 across the Southern Brazilian Pampa. Machine learning models, particularly Random Forest, further improved the precision of reanalysis data for climate applications.

Climatology of Tropical Cyclones Approaching Tanzania and Their Impacts on Rainfall in East Africa

open access: yesInternational Journal of Climatology, EarlyView.
Tropical cyclones (TCs) that approach Tanzania bring heavy rainfall over northern Mozambique, Tanzania, and south‐central Kenya, but the occurrence of these TCs reduces precipitation over southern African countries. Easterly steering winds and the Mascarene High are key features directing TCs westward.

Out of Africa: An alternative scenario for the first human dispersal in Eurasia

open access: yesMètode 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.
