Since the Pyrenean Last Glacial Maximum (75 ka), the deglaciation of the Ésera glacier (central Pyrenees) was characterized by complex dynamics, with advances and rapid retreats. Cosmogenic dates of moraines along the headwaters of the valley and lacustrine sediments analyses allowed to reconstruct evolutionary history of the Ésera glacier and the associated environmental implications during the last deglaciation and calculate the Equilibrium Line Altitude to determine changes in temperature.

This study presents a new speleothem record of the western Mediterranean region that offers new insights into the timeline of glacial terminations TIV, TIII, and TIII.a. The comparison among the studied deglaciations reveals differences in terms of intensity and duration and opens the opportunity to evaluate marine sediment chronologies based on orbital tuning from the North Atlantic and the Western Mediterranean.

Reconstructing past temperatures at regional scales during the Common Era is necessary to place the current warming in the context of natural climate variability. We present a climate reconstruction based on eight stalagmites from four caves in the Pyrenees, NE Spain. These stalagmites were dated precisely and analysed for their oxygen isotopes, which appear dominated by temperature changes. Solar variability and major volcanic eruptions are the two main drivers of observed climate variability.

The Aneto glacier, the largest glacier in the Pyrenees, has shown continuous surface and ice thickness losses in the last decades. In this study, we examine changes in its surface and ice thickness for 1981–2022 and the remaining ice thickness in 2020. During these 41 years, the glacier has shrunk by 64.7 %, and the ice thickness has decreased by 30.5 m on average. The mean ice thickness in 2022 was 11.9 m, compared to 32.9 m in 1981. The results highlight the critical situation of the glacier.

In this work we study the microclimate and the geomorphological features of Devaux ice cave in the Central Pyrenees. The research is based on cave monitoring, geomorphology, and geochemical analyses. We infer two different thermal regimes. The cave is impacted by flooding in late winter/early spring when the main outlets freeze, damming the water inside. Rock temperatures below 0°C and the absence of drip water indicate frozen rock, while relict ice formations record past damming events.

Our study of the chronological sequence of Monte Perdido Glacier in the Central Pyrenees (Spain) reveals that, although the intense warming associated with the Roman period or Medieval Climate Anomaly produced important ice mass losses, it was insufficient to make this glacier disappear. By contrast, recent global warming has melted away almost 600 years of ice accumulated since the Little Ice Age, jeopardising the survival of this and other southern European glaciers over the next few decades.

The manuscript identifies the main volcanic phases in the Laguna del Maule volcanic field and their impact in the lake basin through the late glacial and Holocene. We show that the bio-productivity and geochemical variabilities in the lake are related with climatic dynamics type ENSO, SPA and SWW and that the main phases are synchronous with the major regional climate changes on millennial timescales.

Coccoliths are abundant in sediments across the world’s oceans, yet it is difficult to apply traditional carbon or oxygen isotope methodologies for temperature reconstructions. We show that our coccolith clumped isotope temperature calibration with well-constrained temperatures systematically differs from inorganic carbonate calibrations. We suggest the use of our well-constrained calibration for future coccolith carbonate temperature reconstructions.

Terminations are large magnitude rapid events triggered in the North Atlantic region that manifest across the global climate system. They provide key examples of climatic teleconnections and dynamics. In this study, we use the SISAL global speleothem database and find that there are sufficient climatic records from key locations to make speleothems a valuable archive for studying Terminations and provide instances for more targeted work on speleothem research.

We have monitored water vapor isotopes since January 2020 on Amsterdam Island in the Indian Ocean. We show 11 periods associated with abrupt negative excursions of water vapor δ18Ο. Six of these events show a decrease in gaseous elemental mercury, suggesting subsidence of air from a higher altitude. Accurately representing the water isotopic signal during these cold fronts is a real challenge for the atmospheric components of Earth system models equipped with water isotopes.

The Oligocene and early Miocene periods featured dynamic glacial cycles on Antarctica. In this paper, we use Sr isotopes in marine carbonate sediments to document a change in the location and intensity of continental weathering during short periods of very intense Antarctic glaciation. Potentially, the weathering intensity of old continental rocks on Antarctica was reduced during glaciation. We also show improved age models for correlation of Southern Ocean and North Atlantic sediments.

Stalagmites formed in caves provide valuable information about past changes in climate and vegetation conditions. In this contribution, we present a new method to better estimate past changes in soil and vegetation productivity using carbon isotopes and trace elements measured in stalagmites. Applying this method to other stalagmites should provide a better indication of past vegetation feedbacks to climate change.

Cave monitoring studies including cave drip water are unique opportunities to sample water which has percolated through the soil and rock. The change in drip water chemistry is resolved over the course of 16 months, inferring seasonal and hydrological variations in soil and karst processes at the water–air and water–rock interface. Such data sets improve the understanding of hydrological and hydrochemical processes and ultimately advance the interpretation of geochemical stalagmite records.

Based on the analysis of the response of coccolithophores’ morphological attributes in a laboratory dissolution experiment and surface sediment samples from the South China Sea, we proposed that the thickness shape (ks) factor of fossil coccoliths together with the normalized ks variation, which is the ratio of the standard deviation of ks (σ) over the mean ks (σ/ks), is a robust and novel proxy to reconstruct past changes in deep ocean carbon chemistry.

The Mediterranean Sea is undergoing a rapid and unprecedented environmental change. Planktic foraminifera calcification is affected on different timescales. On seasonal and interannual scales, calcification trends differ according to the species and are linked mainly to sea surface temperatures and carbonate system parameters, while comparison with pre/post-industrial assemblages shows that all three species have reduced their calcification between 10 % to 35 % according to the species.

Past ocean carbon is reconstructed using proxies, but it is unknown whether preparing ocean sediment for one proxy might damage the data given by another. We have tested whether the extraction of an organic proxy archive from sediment samples impacts the geochemistry of tiny shells also within the sediment. We find no difference in shell geochemistry between samples which come from treated and untreated sediment. This will help us to maximize scientific return from valuable sediment samples.

The effect of environmental conditions on the degree of calcification of marine phytoplankton remains unclear. This study implements a new microscopic approach to quantify the calcification of ancient coccolithophores, using North Atlantic sediments. Results show significant differences in the thickness and shape factor of coccoliths for samples with minimum dissolution, providing the first evaluation of phytoplankton physiology adaptation to million-year-scale variable environmental conditions.

Soil respiration is a critical but poorly constrained component of the global carbon cycle. We analyse the effect of changing soil respiration rates on the stable carbon isotope ratio of speleothems from northern Spain covering the last deglaciation. Using geochemical analysis and forward modelling we quantify the processes affecting speleothem stable carbon isotope ratios and extract a signature of increasing soil respiration synchronous with deglacial warming.

The manuscript identifies the main volcanic phases in the Laguna del Maule volcanic field and their impact in the lake basin through the late glacial and Holocene. We show that the bio-productivity and geochemical variabilities in the lake are related with climatic dynamics type ENSO, SPA and SWW and that the main phases are synchronous with the major regional climate changes on millennial timescales.

Drought is a major driver of vegetation activity in Spain. Here we used a high-resolution remote-sensing dataset spanning the period from 1981 to 2015 to assess the sensitivity of 23 vegetation types to drought across Spain. Results demonstrate that vegetation activity is controlled largely by the interannual variability of drought. Nevertheless, there are some considerable spatio-temporal variations, which can be linked to differences in land cover and aridity conditions.

We present a new high-resolution sea surface temperature (SST) reconstruction for the Holocene (last 11 700 years) in the westernmost Mediterranean Sea. We identify three sub-periods: the Early Holocene with warmest SST; the Middle Holocene with a cooling trend ending at 4200 years, which is identified as a double peak cooling event that marks the transition between the Middle and Late Holocene; and the Late Holocene with very different behaviour in both long- and short-term SST variability.

The Mediterranean region has returned some of the clearest evidence of a climatically dry period occurring approximately 4200 years ago. We reviewed selected proxies to infer regional climate patterns between 4.3 and 3.8 ka. Temperature data suggest a cooling anomaly, even if this is not uniform, whereas winter was drier, along with dry summers. However, some exceptions to this prevail, where wetter condition seems to have persisted, suggesting regional heterogeneity.

The sinking speeds of coccoliths are relevant for laboratory methods to separate coccoliths for geochemical analysis. However, in the absence of estimates of coccolith settling velocity, previous implementations have depended mainly on time-consuming method development by trial and error. In this study, the sinking velocities of cocooliths were carefully measured for the first time. We also provide an estimation of coccolith sinking velocity by shape, which will make coccolith separation easier.

We analyzed changes in surface relative humidity (RH) at the global scale from 1979 to 2014 and compared the variability and trends in RH with those in land evapotranspiration and ocean evaporation in moisture source areas across a range of selected regions worldwide. Our results stress that the different hypotheses that may explain the decrease in RH under a global warming scenario could act together to explain recent RH trends.

Changes in atmospheric carbon dioxide affect ocean chemistry and the ability of marine organisms to manufacture shells from calcium carbonate. We describe a technique to obtain more reproducible measurements of the thickness of calcium carbonate shells made by microscopic marine algae called coccolithophores, which will allow researchers to compare how the shell thickness responds to variations in ocean chemistry in the past and present.

This paper presents a new database of past climate proxies which aims to facilitate the distribution of data by using a user-friendly interface. Available data from the last 40 years are often fragmented, with lots of different formats, and online libraries are sometimes nonintuitive. We thus built a new dynamic web portal for data browsing, visualizing, and batch downloading of hundreds of datasets presenting a homogeneous format.

We present a high-resolution multi-proxy study about the evolution of sea surface conditions along the last 2700 yr in the north-western Mediterranean Sea based on five sediment records from two different sites north of Minorca. The novelty of the results and the followed approach, constructing stack records from the studied proxies to preserve the most robust patterns, provides a special value to the study. This complex period appears to have significant regional changes in the climatic signal.

This paper analyzes the evolution of the Monte Perdido Glacier, Spanish Pyrenees, since 1981. Changes in ice volume were estimated by geodetic methods and terrestrial laser scanning. An acceleration in ice thinning is detected during the 21st century. Local climatic changes observed during the study period do not seem sufficient to explain the acceleration. The strong disequilibrium between the glacier and the current climate and feedback mechanisms seems to be the most plausible explanation.

Road and railway embankments contribute importantly to soil and water losses in South-Eastern Spain. Comparing with other land uses as scrubland and citrus plantations, road and railway embankments increased exponentially the amount of sediment transport and runoff. Restoration programs are needed to decrease soil and water losses in these man-made infrastructures.

This manuscript presents new Mg/Ca and previously published δ18O measurements of Neogloboquadrina pachyderma sinistral for MIS 31-19, from a sediment core from the subpolar North Atlantic. The mechanism proposed here involves northward subsurface transport of warm and salty subtropical waters during periods of weaker AMOC, leading to ice-sheet instability and IRD discharge. This is the first time that these rapid climate oscillations are described for the early Pleistocene.

The Rano Aroi peat record (Easter Island, 27ºS) is characterized by six major events of enhanced precipitation between 38 and 65 kyr BP coinciding with Heinrich and Dansgaard-Oeschger (DO) Stadials. These events draw a coherent regional picture involving atmospheric and oceanic reorganization. The singular location of Easter Island, filling a gap in an area where marine records are not available, contributes to understand the mechanisms behind these global rapid climatic excursions.

A seasonal analysis of the nitrogen isotopes of atmospheric nitrate over the remote Southern Ocean reveals that similar natural NOx sources dominate in spring and summer, while winter is representative of background-level conditions. The oxygen isotopes suggest that similar oxidation pathways involving more ozone occur in spring and winter, while the hydroxyl radical is the main oxidant in summer. This work helps to constrain NOx cycling and oxidant budgets in a data-sparse remote marine region.

Nitrate is a critical component of the atmosphere that degrades air quality and ecosystem health. We have investigated the nitrogen isotope compositions of nitrate from deposition samples collected across the northeastern United States. Spatiotemporal variability in the nitrogen isotope compositions was found to track with nitrate formation chemistry. Our results highlight that nitrogen isotope compositions may be a robust tool for improving model representation of nitrate chemistry.

Atmospheric nitrate has an important impact on human and ecosystem health. We evaluated atmospheric nitrate formation pathways in the northeastern US utilizing oxygen isotope compositions, which indicated a significant difference between the phases of nitrate (i.e., gas vs. particle). Comparing the observations with model simulations indicated that N2O5 hydrolysis chemistry was overpredicted. Our study has important implications for improving atmospheric chemistry model representation.

Nitrate isotopes in Antarctic ice do not preserve the seasonal isotopic cycles of the atmosphere, which limits their use to study the past. We studied nitrate along an 850 km Antarctic transect to learn how these cycles are changed by sunlight-driven chemistry in the snow. Our findings suggest that the snow accumulation rate and other environmental signals can be extracted from nitrate with the right sampling and analytical approaches.

Using measurements of methane isotopes in ambient air and a 3D atmospheric transport model, in Krakow, Poland, we mainly detected fossil-fuel-related sources, coming from coal mining in Silesia and from the use of natural gas in the city. Emission inventories report large emissions from coal mine activity in Silesia, which is in agreement with our measurements. However, methane sources in the urban area of Krakow related to the use of fossil fuels might be underestimated in the inventories.

Many coal seam gas (CSG) facilities in the Surat Basin, Australia, are adjacent to other sources of methane, including agricultural, urban, and natural seeps. This makes it challenging to estimate the amount of methane being emitted into the atmosphere from CSG facilities. This research demonstrates that measurements of the carbon and hydrogen stable isotopic composition of methane can distinguish between and apportion methane emissions from CSG facilities, cattle, and many other sources.

Water vapor isotopes recorded for 2 years in coastal northern Greenland largely reflect changes in sea ice cover, with distinct values when Baffin Bay is ice covered in winter vs. open in summer. Resulting changes in moisture transport, surface winds, and air temperature also modify the isotopes. Local glacial ice may thus preserve past changes in the Baffin Bay sea ice extent, and this will help us better understand how the Arctic environment and water cycle responds to global climate change.

We found that Br atoms in the marine boundary layer are the most probable oxidizer that transform gaseous elemental mercury into gaseous oxidized mercury, according to the mercury isotopes in the total gaseous mercury. On the other hand, Br or Cl atoms are not the primary oxidizers that produced oxidized mercury on particles. This study showed that mercury isotopes can provide new evidence that help us to fully understand the transformations of atmospheric mercury.

We observed the isotopic composition of nitrous oxide in the unpolluted air at Jungfraujoch for 5 years. Our results indicate a clear seasonal pattern in the isotopic composition, corresponding with that in atmospheric nitrous oxide levels. This is most likely due to temporal variations in both emission processes and air mass sources for Jungfraujoch. Our findings are of importance to global nitrous oxide modelling and to better understanding of long-term trends in atmospheric nitrous oxide.

The transfer of the nitrogen stable isotopic composition in nitrate between the air and snow at low accumulation sites in Antarctica leaves an UV imprint in the snow. Quantifying how nitrate isotope values change allows us to interpret longer ice core records. Based on nitrate observations and modelling at Kohnen, East Antarctica, the dominant factors controlling the nitrate isotope signature in deep snow layers are the depth of light penetration into the snowpack and the snow accumulation rate.

Given their critical impact on radiative forcing, sulfate aerosols have been extensively studied using their isotope signatures (δ34S, ∆33S, ∆36S, δ18O, and ∆17O). A striking observation is that ∆33S > 0 ‰, implying a missing reservoir in the sulfur cycle. Here, we measured ∆33S < 0 ‰ in black crust sulfates (i.e., formed on carbonate walls) that must therefore result from distinct chemical pathway(s) compared to sulfate aerosols, and they may well represent this complementary reservoir.

We present 14CO2 observations at a background site in Ireland and a tall tower site in the UK. These data have been used to calculate the contribution of fossil fuel sources to atmospheric CO2 mole fractions from the UK and Ireland. 14CO2 emissions from nuclear industry sites in the UK cause a higher uncertainty in the results compared to observations in other locations. The observed ffCO2 at the site was not significantly different from simulated values based on the bottom-up inventory.

Stable isotopes of Carbon Monoxide (CO) and radiocarbon carbon dioxide were measured over three summers at Indianapolis, Indiana, US, and for 1 year at a site thought to be strongly influenced by CO from oxidized volatile organic compounds (VOCs) in South Carolina, US. The Indianapolis results were used to provide an estimate of the carbon and oxygen isotopic signatures of CO produced from oxidized VOCs. This updated estimate agrees well with the data from South Carolina during the summer.

Sulfates present in urban aerosols collected worldwide usually exhibit 33S-anomalies whose origin remains unclear. Besides, the sulfate concentration is not very well modelled nowadays, which, coupled with the isotopic composition anomaly on the 33S, would highlight the presence of at least an additional oxidation pathway, different from O2+TMI, O3, OH, H2O2 and NO2. We suggest here the implication of two other possible oxidation pathways.

Improving air quality requires understanding of the atmospheric processes transforming nitrous oxides emitted by human activities into nitrates, an N form that may degrade natural ecosystems. Isotopes (∆17O, δ18O) are characterized in separate wet, particulate and gaseous nitrates for the first time. The gas ranges are distinct from those of the other nitrates, and the plume dynamics emerge as crucial in interpreting the results, which unravel key processes behind the distribution of nitrates.

Using the observational data on 13C (CO) and 13C (CH4) from the extra-tropical Southern Hemisphere (ETSH) and EMAC model we (1) provide an independent, observation-based evaluation of Cl atom concentration variations in the ETSH throughout 1994–2000, (2) show that the role of tropospheric Cl as a sink of CH4 is seriously overestimated in the literature, (3) demonstrate that the 13C/12C ratio of CO is a sensitive indicator for the isotopic composition of reacted CH4 and therefore for its sources.

Fossil fuel combustion produces water; where fossil fuel combustion is concentrated in urban areas, this humidity source may represent ~ 10 % of total humidity. In turn, this water vapor addition may alter urban meteorology, though the contribution of combustion vapor is difficult to measure. Using stable water isotopes, we estimate that up to 16 % of urban humidity may arise from combustion when the atmosphere is stable during winter, and develop recommendations for application in other cities.

Atmospheric nitrate may be produced locally and/or come from upwind regions. To address this issue we measured oxygen and nitrogen isotopes of wet and dry nitrate deposition at nearby urban and rural sites. Our results suggest that, relative to nitrate in wet deposition in urban environments and wet and dry deposition in rural environments, nitrate in dry deposition in urban environments results from local NOx emissions more so than wet deposition, which is transported longer distances.

We use observations of the oxygen isotopic composition of sulfate aerosol as a fingerprint to quantify various sulfate formation mechanisms during pollution events in Beijing, China. We found that heterogeneous reactions on aerosols dominated sulfate production in general; however, in-cloud reactions would dominate haze sulfate production when cloud liquid water content was high. The findings also suggest the heterogeneity of aerosol acidity should be parameterized in models.

Fossil fuel CO2 is the major contributor of anthropogenic CO2 in the atmosphere, and accurate quantification is essential to better understand the carbon cycle. Such accurate quantification can be conducted based on radiocarbon measurements. In this study, we present radiocarbon measurements from a tall tower site in Switzerland. From these measurements, we have observed seasonally varying fossil fuel CO2 contributions and a biospheric CO2 component that varies diurnally and seasonally.

Nitrous oxide is the third most important anthropogenic greenhouse gas with an increasing mole fraction. To understand its natural and anthropogenic sources
we employ isotope measurements. Results show that while the N2O mole fraction increases, its heavy isotope content decreases. The isotopic changes observed underline the dominance of agricultural emissions especially at the early part of the record, whereas in the later decades the contribution from other anthropogenic sources increases.

We show the first simultaneous observations of triple oxygen isotopic compositions of atmospheric sulfate, nitrate, and ozone at Dumont d'Urville, coastal Antarctica. The contrasting seasonal trends between oxygen isotopes of ozone and those of sulfate and nitrate indicate that these signatures in sulfate and nitrate are mainly controlled by changes in oxidation chemistry. We also discuss the specific oxidation chemistry induced by the unique phenomena at the site.

Methane emissions estimates from the coal sector are highly uncertain. Precise δ13C isotopic signatures of methane sources can be used in atmospheric models for a methane budget assessment. Emissions from both underground and opencast coal mines in the UK, Australia and Poland were sampled and isotopically characterised using high-precision measurements of δ13C values. Representative isotopic signatures were provided, taking into account specific ranks of coal and mine type.

Atmospheric airborne mercury is of particular concern because, once inhaled, both Hg and its vectors might have adverse effects on human beings. In this study, we attempted to identify the sources of PM2.5-Hg in Beijing, China, using Hg isotopic composition. Large range and seasonal variations in both mass-dependent and mass-independent fractionations of Hg isotopes in haze particles demonstrate the usefulness of Hg isotopes for directly tracing the sources and its vectors in the atmosphere.

The formation mechanisms of sulfate in the marine boundary layer are not well understood, which could result in large uncertainties in aerosol radiative forcing. We measure the oxygen isotopic composition (Δ17O) of sulfate collected in the MBL and analyze with a global transport model. Our results suggest that 33–50 % of MBL sulfate is formed via oxidation of S(IV) by hypohalous acids HOBr / HOCl in the aqueous phase, and the daily-mean HOBr/HOCl concentrations are on the order of 0.01–0.1 ppt.

Atmospheric nitrate is collected on the East Antarctic ice sheet. Nitrogen and oxygen stable isotopes and concentrations of nitrate are measured. Using a box model, we show that there is s systematic discrepancy between observations and model results. We suggest that this discrepancy probably results from unknown NOx chemistry above the Antarctic ice sheet. However, possible misconception in the stable isotope mass balance is not completely excluded.

In this field study at Dome C, Antarctica, we investigated the effect of solar UV photolysis on the stable isotopes of nitrate in snow via comparison of two identical snow pits while exposing only one to solar UV. From the difference between the average isotopic fractionations calculated for each pit, we determined a purely photolytic nitrogen isotopic fractionation of -55.8‰, in good agreement with what has been recently determined in a laboratory study.

Short summary
We present a large and unique dataset of the rainfall isotopic composition at seven sites from northern Iberia to characterize their variability at daily and monthly timescales and to assess the role of climate and geographic factors in the modulation of δ18O values. We found that the origin, moisture uptake along the trajectory and type of precipitation play a key role. These results will help to improve the interpretation of δ18O paleorecords from lacustrine carbonates or speleothems.
