This research explores the use of a new isotope tracer, 17O excess, to better understand how hydrological processes drive large seasonal water level changes in small lakes in semiarid regions. The study shows that triple oxygen isotopes offer a more detailed understanding of these changes compared to traditional methods. These findings are valuable for reconstructing past climates and predicting how climate change, influenced by human activity, will affect small lakes in these dry areas.

Data on past relative humidity (RH) ARE needed to improve its representation in Earth system models. A novel isotope parameter (17O-excess) of plant silica has been developed to quantify past RH. Using comprehensive monitoring and novel methods, we show how environmental and plant physiological parameters influence the 17O-excess of plant silica and leaf water, i.e. its source water. The insights gained from this study will help to improve estimates of RH from fossil plant silica deposits.

Continental atmospheric humidity is a key climate parameter poorly captured by global climate models. Model–data comparison approaches that are applicable beyond the instrumental period are essential to progress on this issue but face a lack of quantitative relative humidity proxies. Here, we calibrate the triple oxygen isotope composition of phytoliths as a new quantitative proxy of continental relative humidity suitable for past climate reconstructions.

This study describes an instrumented system of 4 closed aquatic biological chambers that allows determination of the oxygen isotopic fractionation factors of aquatic biosphere in controlled realistic conditions. We validated our system with a freshwater algae species and determined its ¹⁸O/¹⁶O isotopic discrimination during respiration to be −30 ‰, in the upper range of previously published values.

We present a simple workflow for high-precision δ¹³C-CO₂ analysis from 1 mL air samples using cryogenic pre-concentration and continuous-flow isotope-ratio mass spectrometry (IRMS). The method combines vial conditioning, dual sealing, and −80 °C storage to minimise gas loss. It achieves ±0.1 ‰ precision and stable isotopic values for up to one week of storage. This low-cost approach enables high-frequency δ¹³C-CO₂ measurements in volume-limited systems such as microcosm or chamber experiments.

A measurement campaign in Toulon's port in 2021 showed a strong decrease in sulfur-related emissions after IMO2020, while black carbon, organics and polycyclic aromatic hydrocarbons (PAHs) remained at previous levels, as confirmed by their emission factors. Source analysis indicated that ships contributed notably to organic aerosol and alkylated PAHs, and dominated ultrafine particles. These results support continued monitoring as the Mediterranean becomes a sulfur emission control area in 2025.

We reassess the basis for determining the present level of long-term global warming. Unbiased estimates of both realised warming and anthropogenic warming are possible that approximate a 20-year retrospective mean. Our resulting estimates of 1.40 [1.23–1.58] °C (realised) and 1.34 [1.18–1.50] °C (anthropogenic) as at end of 2024 highlight the urgency of immediate, far-reaching and sustained climate mitigation actions if we are to meet the long term temperature goal of the Paris Agreement.

In mountain karst regions, seasonal snow is a key component of groundwater recharge, making them highly vulnerable to climate change. Using a rainfall-snow-discharge model in the southern French Alps, we show that warming shifts high-flow periods and causes a strong summer flow decline. Rapid karst flow paths lead to quick spring responses, limiting storage above the base level and increasing sensitivity to future hydrological change.

The year 2023 saw unexpectedly large global atmospheric CO2 growth. Satellite data reveal a role for increased tropical emissions. Larger emissions over eastern Brazil can be explained by warmer temperatures, which has led to exceptional drought, while hydrological changes play more of a role in emission increases elsewhere in the tropics. Broadly, we find that this situation continues into 2024.

Near-term climate change projections are strongly affected by the uncertainty from internal climate variability. Here, we present a novel approach to reduce this uncertainty by combining information from both observations and decadal predictions to constrain climate projections. This new method can outperform decadal predictions and unconstrained ensemble temperature forecasts in some regions. This improved regional climate information could support more near-term targeted adaptation strategies.

This study estimated regional and sectoral emission contributions to the unprecedented surge of atmospheric methane for 2020–2022. The methane is the second most important greenhouse gas, and its emissions reduction is urgently required to mitigate global warming. Numerical modeling-based estimates with three different sets of atmospheric observations consistently suggested large contributions of biogenic emissions from South Asia and Southeast Asia to the surge of atmospheric methane.

In a rapidly changing climate, evidence-based decision-making benefits from up-to-date and timely information. Here we compile monitoring datasets to track real-world changes over time. To make our work relevant to policymakers, we follow methods from the Intergovernmental Panel on Climate Change (IPCC). Human activities are increasing the Earth's energy imbalance and driving faster sea-level rise compared to the IPCC assessment.

The 2022 fire season had a huge impact on European temperate forest, with several large fires exhibiting prolonged soil combustion reported. We analyzed CO and CO2 concentration recorded at nearby atmospheric towers, revealing intense smoldering combustion. We refined a fire emission model to incorporate this process. We estimated 7.95 Mteq CO2 fire emission, twice the global estimate. Fires contributed to 1.97 % of France's annual carbon footprint, reducing forest carbon sink by 30 % this year.

This paper introduces a new optical gas analyzer based on an optical-feedback cavity-enhanced absorption spectroscopy (OF-CEAS) technique enabling high-temporal-resolution and high-precision measurements of oxygen isotopes (δ18O) and dioxygen (O2) concentration of atmospheric O2 (respectively 0.06 ‰ and 0.002 % over 10 min integration). The results underscore the good agreement with isotope ratio mass spectrometry measurements and the ability of the instrument to monitor biological processes.

The approach presented is original in its coupling between field observations and airborne lidar observations. It has been applied to an instrumented reference forest site in the south of France, which is heavily impacted by climate change. It leads to the evaluation of tree heights and ends with assessments of aerial and root carbon stocks. A detailed assessment of uncertainties is presented to add a level of reliability to the scientific products delivered.

This paper presents the first comprehensive compilation of diatom oxygen isotope records in lake sediments (δ18OBSi), supported by lake basin parameters. We infer the spatial and temporal coverage of δ18OBSi records and discuss common hemispheric trends on centennial and millennial timescales. Key results are common patterns for hydrologically open lakes in Northern Hemisphere extratropical regions during the Holocene corresponding to known climatic epochs, i.e. the Holocene Thermal Maximum.

Understanding the relationship between rivers and alluvial aquifers is crucial, yet challenging. Through a combined approach of tracing and modeling in a French Rhône River site, we reveal significant insights. We quantify the impact of pumping on water flow and identify the primary water sources. Our findings aid sustainable water management in regions facing similar challenges, offering practical guidance for policymakers on groundwater use.

Data on past relative humidity (RH) ARE needed to improve its representation in Earth system models. A novel isotope parameter (17O-excess) of plant silica has been developed to quantify past RH. Using comprehensive monitoring and novel methods, we show how environmental and plant physiological parameters influence the 17O-excess of plant silica and leaf water, i.e. its source water. The insights gained from this study will help to improve estimates of RH from fossil plant silica deposits.

To improve the interpretation of the δ18Oatm and Δ17O of O2 in air bubbles in ice cores, we need to better quantify the oxygen fractionation coefficients associated with biological processes. We performed a simplified analogue of the terrestrial biosphere in a closed chamber. We found a respiration fractionation in agreement with the previous estimates at the microorganism scale, and a terrestrial photosynthetic fractionation was found. This has an impact on the estimation of the Dole effect.

Forecasting temperature patterns beyond 2 weeks is very challenging, although occasionally, forecasts show more skill over Europe. Our study indicates that the level of skill varies concurrently for two distinct forecast systems. It also shows that higher skill occurs when forecasts are issued during specific patterns of atmospheric circulation that tend to be particularly persistent.
These results could help forecasters estimate a priori how trustworthy extended-range forecasts will be.

Currently there is growing interest in monitoring city-scale CO2 emissions based on atmospheric CO2 measurements, atmospheric transport modeling, and inversion technique. We analyze the various sources of uncertainty that impact the atmospheric CO2 modeling and that may compromise the potential of this method for the monitoring of CO2 emission over Paris. Results suggest selection criteria for the assimilation of CO2 measurements into the inversion system that aims at retrieving city emissions.

Short summary
Triple oxygen isotopes (17O-excess) are an upcoming tool in hydrological studies. We present the first one-year high-resolution record of 17O-excess in atmospheric water vapor from a Mediterranean forest site. The dataset provides insights into the processes driving variability of 17O-excess in atmospheric water vapor and precipitation across seasonal, diurnal, and event scales. These findings support model validation efforts and enhance the interpretation of paleoclimate archives.
