Marks-Peterson et al. (2026) measured greenhouse gas concentrations in “blue” ice from the Allan Hills, Antarctica and concluded that atmospheric CO2 was broadly stable over the past ~3 million years....

Studies of Arctic vegetation history during the Holocene have often concluded that significant lags related to dispersal and landscape (soil) developm…

39 laboratories participated in a round robin to determine the reproducibility of glycerol dialkyl glycerol tetraethers (GDGT) proxy values and quantities Peak selection impacts the ratio values ...

Paleoclimatologists have long recognized that H and O isotopes of materials in lake sediments can help reconstruct past climate and environmental change. Here, a global synthesis of O isotopes in lab-...

Position Summary The Climate and Paleoclimate Lab in the Department of Earth, Environmental, and Planetary Sciences at WashU in St. Louis seeks a Postdoctoral Research Associate in tropical climate/pa...

Microbial growth is extremely slow within the first 30 days of thaw. Temperature may drive which taxa are active, but not growth rates Subsurface microbes preferentially produce glycolipids over ...

Serpentinites, hydrated ultramafic rocks that produce [hyper]alkaline, reducing, H2-rich groundwaters, host subsurface microbial ecosystems. Though in the presence of enormous reducing power, life in ...

Easily create overlapping grammar of graphics plots for scientific data visualization. This style of plotting is particularly common in climatology and oceanography research communities.

Abstract. As global warming progresses, changes in high-latitude precipitation are expected to impart long-lasting impacts on earth systems, including glacier mass balance and ecosystem structure. Rec...

Global temperature fluctuations during the last 2,000 years caused consistent changes in ocean evaporation and atmospheric moisture condensation processes, reflected in coherent water isotope signals ...
