Impacts of late‐Holocene climate variability and watershed‐lake interactions on diatom communities in Lac Brûlé, Québec

open access: yesEcosphere, 2017
A high‐resolution diatom analysis of a varved sediment sequence from Lac Brûlé, southwestern Québec, was used to study temporal patterns of environmental change in the late Holocene. Key periods of interest in the record included the Medieval Warm Period

Speleothem Paleoclimatology for the Caribbean, Central America, and North America [PDF]

open access: yes, 2019
Speleothem oxygen isotope records from the Caribbean, Central, and North America reveal climatic controls that include orbital variation, deglacial forcing related to ocean circulation and ice sheet retreat, and the influence of local and remote sea ...

A Study on Possible Solar Influence on the Climate of the Southern Hemisphere

open access: yesAtmosphere, 2022
Three multi-proxy reconstructions of temperature in the Southern Hemisphere, were analyzed over the last millennium. Fourier and wavelet analysis showed that century-scale (55–120 years) and bicentennial (ca 250 years) variability is present in this ...

Pacific Southwest United States Holocene Droughts and Pluvials Inferred From Sediment δ18O (calcite) and Grain Size Data (Lake Elsinore, California) [PDF]

open access: yes, 2019
Records of past climate can inform us on the natural range and mechanisms of climate change. In the arid Pacific southwestern United States (PSW), which includes southern California, there exist a variety of Holocene records that can be used to infer ...

The Atlantic Ocean at the last glacial maximum: 1. Objective mapping of the GLAMAP sea-surface conditions [PDF]

open access: yes, 2003
Recent efforts of the German paleoceanographic community have resulted in a unique data set of reconstructed sea-surface temperature for the Atlantic Ocean during the Last Glacial Maximum, plus estimates for the extents of glacial sea ice.

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 ...

Resonantly Forced Baroclinic Waves in the Oceans: A New Approach to Climate Variability

open access: yesJournal of Marine Science and Engineering, 2020
How variations in Earth’s orbit pace the glacial-interglacial cycles of the Quaternary are probably one of the greatest mysteries of modern climate science.

PaleoRec: A sequential recommender system for the annotation of paleoclimate datasets

open access: yesEnvironmental Data Science, 2022
Studying past climate variability is fundamental to our understanding of current changes. In the era of Big Data, the value of paleoclimate information critically depends on our ability to analyze large volume of data, which itself hinges on ...

Sea surface temperature changes in the southern California borderlands during the last glacial-interglacial cycle [PDF]

open access: yes, 1996
A variety of evidence suggests that average sea surface temperatures (SSTs) during the last glacial maximum in the California Borderlands region were significantly colder than during the Holocene.
