The uranium–thorium (U–Th) and uranium–lead (U–Pb) radiometric dating methods are both suitable for dating carbonate samples ranging in age from about 400 000 to 650 000 years. Here we test agreement between the two methods by dating speleothems (i.e. secondary cave mineral deposits) that are well-suited to both methods. We demonstrate excellent agreement between them and discuss their relative strengths and weaknesses.

We used a random forest approach to produce estimates of monthly precipitation stable isotope variability from 1962–2023, at high resolution across the entire Australian continent. Comprehensive skill and sensitivity testing shows that our random forest models skilfully predict precipitation isotope values in places and times that observations are not available. We make all outputs publicly available, facilitating use in fields from ecology and hydrology to archaeology and forensic science.

The Holocene is marked at 8.2 ka by a North Atlantic freshening event. We investigate its climatic impact in SW France using high-resolution speleothem multiproxy analysis. While the event is seen in some European records, no clear signal appears in ours. This may reflect either limited regional impact, and/or low speleothem sensitivity to the Atlantic event, possibly masked by Mediterranean influence.

This study examines how large ice sheets during the last Ice Age influenced global weather patterns. We found that the presence of these ice sheets affected rainfall patterns in regions like Eurasia and Australia. By altering wind and weather systems, they shifted the position of the tropical rainbelt and impacted the circulation of air in both the Northern and Southern Hemispheres. Our research helps us understand past climate changes and their potential effects on future climate patterns.

Climate change is causing enhanced aridity across many regions of the globe, leading to increased reliance on groundwater resources. We need to understand how groundwater recharge behaves in arid regions over long timescales; unfortunately, arid landscapes tend to preserve very little evidence of their climatic past. We present evidence to suggest that carbonate formations that grow in groundwater can be used as archives of past groundwater recharge in Australia's arid zone.

The Paleochrono-1.1 probabilistic dating model allows users to derive a common and optimized chronology for several paleoclimatic sites from various archives (ice cores, speleothems, marine cores, lake cores, etc.). It combines prior sedimentation scenarios with chronological information such as dated horizons, dated intervals, stratigraphic links and (for ice cores) Δdepth observations. Paleochrono-1.1 is available under an open-source license.

When using the uranium–lead (U–Pb) radiometric dating method on very young materials (e.g. Quaternary age zircon and carbonate minerals), it is important to accurately account for the production and decay of intermediate
daughterisotopes in the uranium-series decay chain. DQPB is open-source software that allows users to easily perform such calculations for a variety of sample types and produce publication-ready graphical outputs of the resulting age information.

The analysis of stable carbon and oxygen isotopic ratios, trace element ratios, and growth rate from a Spanish speleothem provides quantitative information on past hydrological conditions during the early Holocene in south-western Europe. Our data show that the cave site experienced increased effective recharge during the 8.2 ka event. Additionally, the oxygen isotopes indicate a change in the isotopic composition of the moisture source, associated with the meltwater flux to the North Atlantic.

Short summary
The U–Th ages of subglacial carbonate deposits from a recently exposed surface previously occupied by the disappearing glacier in the SE European Alps suggest the glacier’s presence throughout the entire Holocene. These thin deposits, formed by regelation, would have been easily eroded if exposed during previous Holocene climatic optima. The age data indicate the glacier’s present unprecedented level of retreat and the potential of subglacial carbonates to act as palaeoclimate proxies.

Short summary
Past studies used two sampling strategies, the "bulk" and "sequential" drilling methods, for stable isotopic analysis of mammoth tooth enamel and paleoenvironmental reconstruction. This study applied both methods to the same enamel ridges of multiple mammoth teeth and compared their respective δ18O values. Offsets were detected between the bulk and average sequential δ18O values. The potential reasons for the offsets and their impacts on cross-method data comparison were discussed.
