The impact of neogene grassland expansion and aridification on the isotopic composition of continental precipitation [PDF]
The late Cenozoic was a time of global cooling, increased aridity, and expansion of grasslands. In the last two decades numerous records of oxygen isotopes have been collected to assess plant ecological changes, understand terrestrial paleoclimate, and ...

ABSTRACT This study applies Δ₄₇/U–Pb thermochronology to the Middle Jurassic carbonates exposed in the southeastern margin of the Paris Basin. By integrating clumped isotope analyses and U–Pb dating of diagenetic carbonates, we reconstruct the thermal and exhumation history of the sedimentary succession.

Contrasting intrainterstadial climatic evolution between high and middle North Atlantic latitudes: A close-up of Greenland Interstadials 8 and 12 [PDF]
Three highly resolved pollen and sea surface temperature records from the Iberian margin (36â "42°N) reveal the local evolution of vegetation and climate associated with the rapid climatic variability of marine isotope stage 3.

ABSTRACT Future projections of climate change in the subtropics suggest warming and drying, while evidence from warm periods in the past shows increases in subtropical temperatures and precipitation. Eastern Australia is subject to interannual hydroclimate drivers and has experienced extreme flooding and droughts in recent years.

Permafrost hydrology in changing climatic conditions: seasonal variability of stable isotope composition in rivers in discontinuous permafrost [PDF]
Role of changing climatic conditions on permafrost degradation and hydrology was investigated in the transition zone between the tundra and forest ecotones at the boundary of continuous and discontinuous permafrost of the lower Yenisei River.

Abstract Coastal aquifers in the Mediterranean are increasingly stressed by climate change, intensive agriculture, and rising water demand. In Malta island, where groundwater is a key resource, nitrate contamination remains a persistent issue despite regulatory efforts and the designation of the islands as a Nitrate Vulnerable Zone.

Mapping Arsenic Risks in the Ayeyarwady (Irrawaddy) Delta, Myanmar: Implications for Public Health
Abstract The Ayeyarwady Delta in Myanmar, home to an estimated 12 million people, faces widespread arsenic contamination similar to other Asian deltas namely Bengal, Red River, and Mekong. Arsenic here primarily results from reductive dissolution of iron minerals in anoxic conditions driven by organic carbon. Here, we used digital elevation model (DEM)
