This article discusses the 100 most important questions facing Earth and Geosciences in the twenty-first century according to the largest of the LLMs. The study uncovered a discrepancy in responses using the synonymous terms earth sciences and geosciences ; as such, users of publicly accessible LLMs must account for this bias and exercise caution in interpretation. Eight fundamental topics irrespective of the query terms earth sciences/geosciences were found: while two of them originate from fundamental research in extraterrestrial geoscience and Earth’s interior, the remaining six address geoscientific questions, important due to the associated societal challenges and environmental issues. The outlined eight fundamental topics strongly resonate with eight Sustainable Development Goals of the United Nations, in certain cases with not just one.

The lab has the proper sampling equipment for field work, a sanding workshop to prepare tree-ring samples for measurement and measuring-stages with software for recording and analyzing tree-ring data. Throughout the first 20 years of activity the BTRL collected and analyzed ∼360 living and ∼470 relict samples (including historical and subfossil material) from more than 33 sites distributed mainly in Europe but including a few localities in Asia. The most represented genera are Quercus and Pinus , both among the living and the relic subsets. Open access publication of the essential ancillary scientific information of the stored material will make the sample archive of the BTRL an actual national research infrastructure.

The dendrogeomorphic method was applied, for the first time, at Xiaolong Mts in Gansu Province to obtain a quantitative estimate of the soil erosion rate. The dataset built in this pilot study allowed the identification of exhumation texture in exposed roots between 1967 and 2002. The calculated mean erosion rate estimates (Era) ranged from 2.6 to 16.5 mm yr−1 and showed an increase with the slope steepness (s). The best fitting linear model (Era = 0.043(±0.017) × s + 3.09(±1.04); R² = 0.20; R²adj = 0.16; F = 6.18; p = 0.02) could be used in future research to determine and to map soil denudation in this part of the Xiaolong Mts. Notable associations were found between erosive rainfalls and root exhumation events. Daily (Rx1day) and 5-day (Rx5day) precipitation totals of 56 and 73 mm, respectively, seem to be critical thresholds which if exceeded will always induce root exhumation in the same year or in the consecutive season in the forest of the Xiaolong Mts in the studied period.

Palaeoclimate information on multiple climate variables at different spatiotemporal scales is becoming increasingly important to understand environmental and societal responses to climate change. A lack of high-quality reconstructions of past hydroclimate has recently been identified as a critical research gap. Speleothems, with their precise chronologies, widespread distribution, and ability to record changes in local to regional hydroclimate variability, are an ideal source of such information. Here, we present a new version of the Speleothem Isotopes Synthesis and AnaLysis database (SISALv3), which has been expanded to include trace element ratios and Sr isotopes as additional, hydroclimate-sensitive geochemical proxies. The oxygen and carbon isotope data included in previous versions of the database have been substantially expanded. SISALv3 contains speleothem data from 365 sites from across the globe, including 95 Mg/Ca, 85 Sr/Ca, 52 Ba/Ca, 25 U/Ca, 29 P/Ca, and 14 Sr-isotope records. The database also has increased spatiotemporal coverage for stable oxygen (892) and carbon (620) isotope records compared with SISALv2 (which consists of 673 and 430 stable oxygen and carbon records, respectively). Additional meta information has been added to improve the machine-readability and filtering of data. Standardized chronologies are included for all new entities along with the originally published chronologies. Thus, the SISALv3 database constitutes a unique resource of speleothem palaeoclimate information that allows regional to global palaeoclimate analyses based on multiple geochemical proxies, permitting more robust interpretations of past hydroclimate and comparisons with isotope-enabled climate models and other Earth system and hydrological models. The database can be accessed at https://doi.org/10.5287/ora-2nanwp4rk (Kaushal et al., 2024).
