Many important processes within the global mercury (Hg) cycle operate over thousands of years. Here, we explore the timing, magnitude, and expression of Hg signals retained in sediments of lakes Prespa and Ohrid over the past ∼90 000 years. Divergent signals suggest that local differences in sediment composition, lake structure, and water balance influence the local Hg cycle and determine the extent to which sedimentary Hg signals reflect local- or global-scale environmental changes.

Climate changes occur today as they occurred in the past. This study deals with climate changes reconstructed at Lake Ohrid (Albania and FYROM) between 160 000 and 70 000 years ago. Climate reconstruction, based on a high-resolution pollen study, provides quantitative estimates of past temperature and precipitation. Our data show an alternation of cold/dry and warm/wet periods. The last interglacial appears to be characterized by temperatures higher than nowadays.

The first high-resolution Lake Dojran pollen record for the last 12 500 years is presented. The ecological succession shows Late Glacial steppe vegetation gradually replaced, since 11 500 yr BP, by Holocene mesophilous forests. The first human traces are recorded around 5000 yr BP and increased considerably since the Bronze Age. Pollen data and sedimentological, biomarker and diatom data available from the same core contribute to an understanding of the environmental history of the Balkans.

Lake Ohrid is considered to be the oldest existing lake in Europe. Moreover, it has a very high degree of endemic biodiversity. During a drilling campaign at Lake Ohrid in 2013, a 569 m long sediment sequence was recovered from Lake Ohrid. The ongoing studies of this record provide first important information on the environmental and evolutionary history of the lake and the reasons for its high endimic biodiversity.

Chronology is fundamental in paleoclimatology for understanding timing of events and their origin. In this paper we try to obtain a more detailed chronology for the interval comprised between ca. 140 and 70 ka for the DEEP core in Lake Ohrid using regional independently-dated archives (i.e. speleothems and/or lacustrine succession with well-dated volcanic layers). This allows to insert the DEEP chronology within a common chronological frame between different continental and marine proxy records.

The magnetic record from Lake Ohrid reflects a strong change in geochemical conditions in the lake. Before 320 ka glacial sediments contain iron sulfides, while later glacials are dominated by siderite. Superimposed on this large-scale pattern are climatic induced changes in the magnetic mineralogy. Glacial and stadial sediments are characterized by relative increases of high- vs. low-coercivity minerals which relate to enhanced erosion in the catchment, possibly due to a sparse vegetation.

We use stable isotope data from carbonates to provide a palaeoenvironmental reconstruction covering the last 637 kyr at Lake Ohrid (FYROM/Albania). Our results indicate a relatively stable climate until 450 ka, wetter climate conditions at 400–250 ka, and a transition to a drier climate after 250 ka. This work emphasises the importance of Lake Ohrid as a valuable archive of climate change in the northern Mediterranean region.

Lake Ohrid (FYROM/Albania) is the deepest, largest and oldest lake in Europe. To understand the climatic and environmental evolution of its area, a palynological study was undertaken for the last 500 ka. We found a correspondence between forested/non-forested periods and glacial-interglacial cycles of marine isotope stratigraphy. Our record shows a progressive change from cooler and wetter to warmer and dryer interglacial conditions. This shift is also visible in glacial vegetation.

Gamma ray (GR) fluctuations and K values from downhole logging data obtained in the sediments of Lake Ohrid correlate with the global climate reference record (LR04 stack from δ18O) (Lisiecki and Raymo, 2005). GR and K values are considered a reliable proxy to depict glacial-interglacial cycles and document warm, humid and cold, drier periods. A robust age model for the downhole logging data over the past 630kyr was established and will play a crucial role for other working groups.

Short summary
We studied climate change in the central Mediterranean during the Holocene by analysing 38 pollen records. Several methods were used to obtain reliable results on seasonal temperatures and precipitation. Our results show that, during the Holocene, summer temperatures were colder in the south and warmer in the north, with wetter winters and drier summers, especially in the south. Unlike winter conditions, summers ones did not follow variations in insolation, suggesting other factors.

A total of 42 Earth scientists from 14 countries met in Gioia dei Marsi, central Italy, on 23 to 27 October 2023 to explore the potential for deep drilling of the thick lake sediment sequence of the Fucino Basin. The aim was to reconstruct the history of climate, ecosystem, and biodiversity changes and of the explosive volcanism and tectonics in central Italy over the last 3.5 million years, constrained by a detailed radiometric chronology.

The uranium-thorium and uranium-lead radiometric dating methods are both capable of dating carbonate samples ranging in age from about 400,000 to 650,000 years. Here we test agreement between the two methods by 'double dating' speleothems (i.e. secondary cave mineral deposits) that grew within this age range. We demonstrate excellent agreement between the two dating methods and discuss their relative strengths and weaknesses.

Pyroclastic deposits are the only records left by pyroclastic flows at Vesuvius, deposits from past eruptions are the only way to get hints about the expected range of impact parameters. It is necessary to investigate the deposits first, then define a general model of the current that links deposit characteristics to flow dynamics, and finally reconstruct the impact parameters that better represent flow intensity in terms of damaging potential. This is the way the paper is organized.

We study the lahar hazard due to the remobilization of tephra deposits from reference eruptions at Somma–Vesuvius. To this end, we rely on the results of two companion papers dealing with field data and model calibration and run hundreds of simulations from the catchments around the target area to capture the uncertainty in the initial parameters. We process the simulations to draw maps of the probability of overcoming thresholds in lahar flow thickness and dynamic pressure relevant for risk.

We study the distribution of two historical pyroclastic fall–flow and lahar deposits from the sub-Plinian Vesuvius eruptions of 472 CE Pollena and 1631. The motivation comes directly from the widely distributed impact that both the eruptions and lahar phenomena had on the Campanian territory, not only around the volcano but also down the nearby Apennine valleys. Data on about 500 stratigraphic sections and modeling allowed us to evaluate the physical and dynamical impact of these phenomena.

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.

A new methodology to calculate a probabilistic long-term tephra fallout hazard assessment in southern Italy from the Neapolitan volcanoes is provided. By means of thousands of numerical simulations we quantify the mean annual frequency with which the tephra load at the ground exceeds critical thresholds in 50 years. The output hazard maps account for changes in eruptive regimes of each volcano and are also comparable with those of other natural disasters in which more sources are integrated.

The investigation of a 9 m long sediment core recovered at ca. 300 m water depth demonstrates that cold-water coral mound build-up within the East Melilla Coral Province (southeastern Alboran Sea) took place during both interglacial and glacial periods. Based on the combination of different analytical methods (e.g. radiometric dating, micropaleontology), we propose that corals never thrived but rather developed under stressful environmental conditions.

Levinson-Lessing Lake in northern central Siberia provides an exceptional opportunity to study the evolution of the Earth's magnetic field in the Arctic. This is the first study carried out at the lake that focus on the palaeomagnetic record. It presents the relative palaeointensity and palaeosecular variation of the upper 38 m of sediment core Co1401, spanning ~62 kyr. A comparable high-resolution record of this time does not exist in the Eurasian Arctic.

Anoxia in lakes is a major growing concern. In this study we applied a multiproxy approach combining high-resolution hyperspectral imaging (HSI) pigment data with specific HPLC data to examine the Holocene evolution and main drivers of lake anoxia and trophic state changes. We find that when human impact was low, these changes were driven by climate and natural lake-catchment evolution. In the last 500 years, increasing human impact has promoted lake eutrophication and permanent anoxia.

In this work we provide a 2D finite-element modelling of the stress field conditions around the Fuego de Colima volcano (Mexico) in order to test the response of the commercial Linear Static Analysis software to increasingly different geological constraints. Results suggest that an appropriate set of geological and geophysical data improves the mesh generation procedures and the degree of accuracy of numerical outputs, aimed at more reliable physics-based representations of the natural system.

Earth has experienced remarkable climate–environmental changes in the last 65 million years. The Weihe Basin with its 6000–8000 m infill of a continuous sedimentary sequence gives a unique continental archive for the study of the Cenozoic environment and exploration of deep biospheres. This workshop report concludes key objectives of the two-phase Weihe Basin Drilling Project and the global significance of reconstructing Cenozoic climate evolution and tectonic–monsoon interaction in East Asia.

PalaeoCADIX-Z is an interdisciplinary project that studied three cores drilled in a marine palaeochannel that ran through the ancient city of Cádiz (Spain). These cores reveal a ≥ 50 m thick Holocene sedimentary sequence. Importantly, most of the deposits date from the 1st millennium BCE to the 1st millennium CE. Geoarchaeologists, geomorphologists, archaeologists, sedimentologists, palaeoenvironmentalists, geochemists, and geochronologists collaborated within this project.

Ferruginous lakes experience restricted primary production due to phosphorus trapping by ferric iron oxides under oxic conditions. We report the presence of large crystals of vivianite, a ferrous iron phosphate, in sediments from Lake Towuti, Indonesia. We address processes of P retention linked to diagenesis of iron phases. Vivianite crystals had light Fe2+ isotope signatures and contained mineral inclusions consistent with antecedent processes of microbial sulfate and iron reduction.

The Fuego de Colima volcano (Mexico) shows a complex eruptive history, with periods of rapid and slow lava dome growth punctuated by explosive activity. Here we reconstructed the 1998–2018 average discharge rate by means of satellite thermal data and the literature. Using spectral and wavelet analysis, we found a multi-term cyclic behavior that is in good agreement with numerical modeling, accounting for a variable magmatic feeding system composed of a single or double magma chamber system.

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.

To understand the natural variability in the climate system, the hydrological aspect (dry and wet conditions) is particularly important for its impact on our societies. The reconstruction of past precipitation regimes can provide a useful tool for forecasting future climate changes. We use multi-proxy time series (oxygen and carbon isotopes, trace elements) from a speleothem to investigate circulation pattern variations and seasonality effects during the dry 4.2 ka event in central Italy.

Climate changes occur today as they occurred in the past. This study deals with climate changes reconstructed at Lake Ohrid (Albania and FYROM) between 160 000 and 70 000 years ago. Climate reconstruction, based on a high-resolution pollen study, provides quantitative estimates of past temperature and precipitation. Our data show an alternation of cold/dry and warm/wet periods. The last interglacial appears to be characterized by temperatures higher than nowadays.

The first high-resolution Lake Dojran pollen record for the last 12 500 years is presented. The ecological succession shows Late Glacial steppe vegetation gradually replaced, since 11 500 yr BP, by Holocene mesophilous forests. The first human traces are recorded around 5000 yr BP and increased considerably since the Bronze Age. Pollen data and sedimentological, biomarker and diatom data available from the same core contribute to an understanding of the environmental history of the Balkans.

We explored the potential of a sedimentary sequence in Valle d'Aosta (Northern Italy) as a natural archive of hazards. Our results suggest that this sequence is regionally the most sensitive to earthquake shaking with the record of 8 earthquakes over the last ~270 years and that it well represents the regional and (multi-)decennial variability of Mediterranean summer–autumn floods. Hence, this sequence offers a great potential to extend chronicles of regional floods and earthquakes back in time.

Lake Ohrid is considered to be the oldest existing lake in Europe. Moreover, it has a very high degree of endemic biodiversity. During a drilling campaign at Lake Ohrid in 2013, a 569 m long sediment sequence was recovered from Lake Ohrid. The ongoing studies of this record provide first important information on the environmental and evolutionary history of the lake and the reasons for its high endimic biodiversity.

This study aims to reconstruct the climate evolution of the Mediterranean region during the Holocene from pollen data and model outputs. The model- and pollen-inferred precipitation estimates show overall agreement: the eastern Medit. experienced wetter-than-present summer conditions during the early–late Holocene. This regional climate model highlights how the patchy nature of climate signals and data in the Medit. may lead to stronger local signals than the large-scale pattern suggests.

The Towuti Drilling Project seeks to understand the long-term environmental and climatic history of the tropical western Pacific and to discover the unique microbes that live in metal-rich sediments. To accomplish these goals, in 2015 we carried out a scientific drilling project on Lake Towuti, located in central Indonesia. We recovered over 1000 m of core, and our deepest core extended 175 m below the lake floor and gives us a complete record of the lake.

Chronology is fundamental in paleoclimatology for understanding timing of events and their origin. In this paper we try to obtain a more detailed chronology for the interval comprised between ca. 140 and 70 ka for the DEEP core in Lake Ohrid using regional independently-dated archives (i.e. speleothems and/or lacustrine succession with well-dated volcanic layers). This allows to insert the DEEP chronology within a common chronological frame between different continental and marine proxy records.

The magnetic record from Lake Ohrid reflects a strong change in geochemical conditions in the lake. Before 320 ka glacial sediments contain iron sulfides, while later glacials are dominated by siderite. Superimposed on this large-scale pattern are climatic induced changes in the magnetic mineralogy. Glacial and stadial sediments are characterized by relative increases of high- vs. low-coercivity minerals which relate to enhanced erosion in the catchment, possibly due to a sparse vegetation.

We use stable isotope data from carbonates to provide a palaeoenvironmental reconstruction covering the last 637 kyr at Lake Ohrid (FYROM/Albania). Our results indicate a relatively stable climate until 450 ka, wetter climate conditions at 400–250 ka, and a transition to a drier climate after 250 ka. This work emphasises the importance of Lake Ohrid as a valuable archive of climate change in the northern Mediterranean region.

Lake Ohrid (FYROM/Albania) is the deepest, largest and oldest lake in Europe. To understand the climatic and environmental evolution of its area, a palynological study was undertaken for the last 500 ka. We found a correspondence between forested/non-forested periods and glacial-interglacial cycles of marine isotope stratigraphy. Our record shows a progressive change from cooler and wetter to warmer and dryer interglacial conditions. This shift is also visible in glacial vegetation.

The long-term response of the flood activity to both Atlantic and Mediterranean climatic influences was explored by reconstructing the Foréant record. Both influences result in a higher flood frequency during past cold periods. Atlantic influences seem to result in more frequent high-intensity flood events during past warm periods, suggesting an increase in flood intensity under the global warming. However, no high-intensity events occurred during the 20th century.

In this paper we use two climate models to test how Earth’s vegetation responded to changes in climate over the last 120 000 years, looking at warm interglacial climates like today, cold ice-age glacial climates, and intermediate climates. The models agree well with observations from pollen, showing smaller forested areas and larger desert areas during cold periods. Forests store most terrestrial carbon; the terrestrial carbon lost during cold climates was most likely relocated to the oceans.

Gamma ray (GR) fluctuations and K values from downhole logging data obtained in the sediments of Lake Ohrid correlate with the global climate reference record (LR04 stack from δ18O) (Lisiecki and Raymo, 2005). GR and K values are considered a reliable proxy to depict glacial-interglacial cycles and document warm, humid and cold, drier periods. A robust age model for the downhole logging data over the past 630kyr was established and will play a crucial role for other working groups.

As a pilot study for a possible depth-drilling project, an 82m long sedimentary succession was retrieved from the Fucino Basin, central Apennines, which hosts ca. 900m of lacustrine sediments. The acquired paleoclimatic record, from the retrieved core, spans the last 180ka and reveals noticeable variations related to the last two glacial-interglacial cycles. In light of these results, the Fucino sediments are likely to provide one of the longest continuous record for the last 2Ma.

Leaching experiments were carried out on fresh ash samples from the 2012 Popocatépetl, and 2011/12 Etna eruptions, in order to investigate the release of compounds in water. Results were discussed in the light of changing pH and release of compounds for the different leachates. They were used for toxicity experiments on living biota (Xenopus laevis). They are mildly toxic, and no significant differences exist between the toxic profiles of the two leachates.

The stable isotope composition of benthic sponge silica skeletons (spicules) has been shown to be a source of useful palaeoceanographic information about past deep seawater chemistry. Here, we investigate the biological vital effects on silica stable isotope composition in a Southern Ocean carnivorous sponge, Asbestopluma sp. We find significant variations in isotopic composition within the specimen – in both silicon and oxygen isotopes – that appear to be related to unusual spicule growth.

Lake Vida is one of the largest lakes in the McMurdo dry valleys, Antarctica, and has the thickest known ice cover of any lake on Earth. For the first time, Lake Vida was drilled to a depth of 27m. With depth the ice cover changes from freshwater ice to salty ice interspersed with thick sediment layers. It is hypothesized that the repetition of sediment layers in the ice will reveal climatic and hydrologic variability in the region over the last 1000--3000 years.

This study analyzes atmospheric CO2 concentrations and global carbon budgets simulated by multiple Earth system models, using several types of simulations (CO2 concentration- and emission-driven experiments). We successfully identified problems with regard to the global carbon budget in each model. We also found urgent issues with regard to land use change CO2 emissions that should be solved in the latest generation of models.

Allometric equations predict tree biomass and are crucial for estimating forest carbon storage, thus assessing the role of forests in climate change mitigation. Usually, these equations are selected based on tree-level predictive performance. However, we evaluated the model performance at plot and forest levels, finding it varies with plot size. This has significant implications for reducing uncertainty in biomass estimates at these levels.

Research on the influences of dynamic pH on the marine ecosystem is still in its infancy.

Using novel Earth system model simulations and applying the Aerobic Growth Index, we show that only about half of the habitat loss for marine species is realized when temperature stabilization is initially reached. The maximum habitat loss happens over a century after peak warming in a temperature overshoot scenario peaking at 2 °C before stabilizing at 1.5 °C. We also emphasize that species adaptation may be key in mitigating the long-term impacts of temperature stabilization and overshoot.

Ozone (O3) pollution reduces wheat yields and quality in India, affecting amino acids essential for nutrition, like lysine and methionine. Here, we improve the DO3SE-CropN model to simulate wheat’s protective processes against O3 and their impact on protein and amino acid concentrations. While the model captures O3-induced yield losses, it underestimates amino acid reductions. Further research is needed to refine the model, enabling future risk assessments of O3's impact on yields and nutrition.

The identification of the most mechanistically realistic models allows for a substantial reduction in projection uncertainty.

The environmental impacts of ocean alkalinity enhancement (OAE) are unknown. Our synthesis, based on 68 collected studies with 84 unique species, shows that 35 % of species respond positively, 26 % respond negatively, and 39 % show a neutral response to alkalinity addition. Biological thresholds were found from 50 to 500 µmol kg−1 NaOH addition. A precautionary approach is warranted to avoid potential risks, while current regulatory framework needs improvements to assure safe biological limits.

Marine enhanced rock weathering (mERW) with olivine is a promising method for capturing CO2 from the atmosphere, yet studies in field conditions are lacking. We bridge the gap between theoretical studies and the real-world environment by estimating the predictability of mERW parameters and identifying aspects to consider when applying mERW. A major source of uncertainty is the lack of experimental studies with sediment, which can heavily influence the speed and efficiency of CO2 drawdown.

Ocean alkalinity enhancement (OAE) is a negative emission technology which may alter marine communities and the particle export they drive. Here, impacts of carbonate-based OAE on the flux and attenuation of sinking particles in an oligotrophic plankton community are presented. Whilst biological parameters remained unaffected, abiotic carbonate precipitation occurred. Among counteracting OAE’s efficiency, it influenced mineral ballasting and particle sinking velocities, requiring monitoring.

Leaf water potential was at certain thresholds, depending on soil type, water treatment, and weather conditions. In rainfed plots, the lower water availability in the stony soil resulted in fewer roots with a higher root tissue conductance than the silty soil. In the silty soil, higher stress in the rainfed soil led to more roots with a lower root tissue conductance than in the irrigated plot. Crop responses to water stress can be opposite, depending on soil water conditions that are compared.

In 2022, Europe's forests faced unprecedented dry conditions. Our study aimed to understand how different forest types respond to extreme drought. Using meteorological data and satellite imagery, we compared 2022 with two previous extreme years, 2003 and 2018. Despite less severe drought in 2022, forests showed a 30 % greater decline in photosynthesis compared to 2018 and 60 % more than 2003. This suggests an alarming level of vulnerability of forests across Europe to more frequent droughts.

The remaining carbon budget (RCB) represents the allowable future CO2 emissions before a temperature target is reached. Understanding the uncertainty in the RCB is critical for effective climate regulation and policy-making. One major source of uncertainty is the representation of the carbon cycle in Earth system models. We assessed how nutrient limitation affects the estimation of the RCB. We found a reduction in the estimated RCB when nutrient limitation is taken into account.

At ground level, the air pollutant ozone (O3) damages wheat yield and quality. We modified the DO3SE-Crop model to simulate O3 effects on wheat quality and identified onset of leaf death as the key process affecting wheat quality upon O3 exposure. This aligns with expectations, as the onset of leaf death aids nutrient transfer from leaves to grains. Breeders should prioritize wheat varieties resistant to protein loss from delayed leaf death, to maintain yield and quality under O3 exposure.

Recent studies described the precipitation of carbonates as a result of alkalinity enhancement in seawater, which could adversely affect the carbon sequestration potential of ocean alkalinity enhancement (OAE) approaches. By conducting experiments in natural seawater, this study observed uniform patterns during the triggered runaway carbonate precipitation, which allow the prediction of safe and efficient local application levels of OAE scenarios.

Changes in pH generate stress conditions, either because high pH drastically decreases the availability of trace metals such as Fe(II), a restrictive element for primary productivity, or because reactive oxygen species are increased with low pH. The metabolic functions and composition of microalgae can be affected. These modifications in metabolites are potential factors leading to readjustments in phytoplankton community structure and diversity and possible alteration in marine ecosystems.

This study simulates long-term future climate scenarios to examine how long CO2 emissions will persist in the atmosphere. It shows that the effectiveness of carbon removal processes varies with the amount emitted. The removal of CO2 through silicate weathering is faster than previously thought, leading to a quicker reduction over time. The combined behaviour of different carbon cycle processes emphasizes the need to include all of them in models, as to better predict long-term atmospheric CO2.

Our research explores how chickpea plants can absorb essential nutrients like phosphorus, iron, and nickel directly from dust deposited on their leaves, in addition to uptake through their roots. This process was particularly effective under higher levels of atmospheric CO2, leading to increased plant growth. By using Nd isotopic tools, we traced the nutrients from dust and found that certain leaf traits enhance this uptake. This discovery may become increasingly important as CO2 levels rise.

Tackling climate change by adding, restoring, or enhancing forests is gaining global support. However, it is important to investigate the broader implications of this. We used a computer model of the Earth to investigate a future where tree cover expanded as much as possible. We found that some tropical areas were cooler because of trees pumping water into the atmosphere, but this also led to soil and rivers drying.

How do perpetually slower and warmer oceans sequester carbon? Compared to the preindustrial state, we find that biological productivity declines despite warming-stimulated growth because of a lower nutrient supply from depth. This throttles the biological carbon pump, which still sequesters more carbon because it takes longer to return to the surface. The deep ocean is isolated from the surface, allowing more carbon from the atmosphere to pass through the ocean without contributing to biology.

To mitigate our impact on the climate, research suggests that we will need to both drastically reduce emissions and perform carbon dioxide removal (CDR). We simulated future climates under three emissions scenarios, in which we removed some carbon from the air and put it into agricultural soil at varying rates. We found that agricultural CDR is much more effective at reducing global temperatures if done in a low emissions scenario and at a high rate, and it becomes less effective with time.

This paper explores the climate processes that drive increasing global average temperatures in zero-emission commitment (ZEC) simulations despite decreasing atmospheric CO2. ACCESS-ESM1.5 shows the Southern Ocean to continue to warm locally in all ZEC simulations. In ZEC simulations that start after the emission of more than 1000 Pg of carbon, the influence of the Southern Ocean increases the global temperature.

We mapped the distribution of future potential afforestation regions based on future high-resolution climate data and climate–vegetation models. After considering the national afforestation policy and climate change, we found that the future potential afforestation region was mainly located around and to the east of the Hu Line. This study provides a dataset for exploring the effects of future afforestation.

Phytoplankton play a crucial role in marine ecosystems. However, climate change's impact on phytoplankton biomass remains uncertain, particularly in the Southern Ocean. In this region, phytoplankton biomass within the water column is likely to remain stable in response to climate change, as supported by models. This stability arises from a shallower mixed layer, favoring phytoplankton growth but also increasing zooplankton grazing due to phytoplankton concentration near the surface.

We present coherence and time lags in spectral response of three vegetation types in the European temperate zone to the influencing meteorological factors and teleconnection indices for the period 2002–2022. Vegetation condition in broadleaved forest, coniferous forest and pastures was measured with MODIS NDVI and EVI, and the coherence between NDVI and EVI and meteorological elements was described using the methods of wavelet coherence and Pearson’s linear correlation with time lag.

Ash particles from wildfires are rich in phosphorus (P), a crucial nutrient that constitutes a limiting factor in 43 % of the world's land ecosystems. We hypothesize that wildfire ash could directly contribute to plant nutrition. We find that fire ash application boosts the growth of plants, but the only way plants can uptake P from fire ash is through the foliar uptake pathway and not through the roots. The fertilization impact of fire ash was also maintained under elevated levels of CO2.

Disturbances (e.g. fire) can change which species grow in a forest, affecting water, carbon, energy flows, and the climate. They are expected to increase with climate change, but it is uncertain by how much. We studied how future climate and disturbances might impact vegetation with a simulation model. Our findings highlight the importance of considering both factors, with future disturbance patterns posing significant uncertainty. More research is needed to understand their future development.

The general impact of afforestation on the regional climate conditions in Europe during the period 1986–2015 is investigated. For this purpose, a regional climate model simulation is performed, in which afforestation during this period is considered, and results are compared to a simulation in which this is not the case. Results show that afforestation had discernible impacts on the climate change signal in Europe, which may have mitigated the local warming trend, especially in summer in Europe.

Carbon cycle feedback metrics are employed to assess phases of positive and negative CO2 emissions. When emissions become negative, we find that the model disagreement in feedback metrics increases more strongly than expected from the assumption that the uncertainties accumulate linearly with time. The geographical patterns of such metrics over land highlight that differences in response between tropical/subtropical and temperate/boreal ecosystems are a major source of model disagreement.

Ocean acidity extremes in the upper 250 m depth of the northeastern Pacific rapidly increase with atmospheric CO2 rise, which is worrisome for marine organisms that rapidly experience pH levels outside their local environmental conditions. Presented research shows the spatiotemporal heterogeneity in this increase between regions and depths. In particular, the subsurface increase is substantially slowed down by the presence of mesoscale eddies, often not resolved in Earth system models.

Anthropogenic climate change will influence marine phytoplankton over the coming century. Here, we quantify the influence of anthropogenic climate change on marine phytoplankton internal variability using an Earth system model ensemble and identify a decline in global phytoplankton biomass variance with warming. Our results suggest that climate mitigation efforts that account for marine phytoplankton changes should also consider changes in phytoplankton variance driven by anthropogenic warming.

We quantify the impact of CO2 and climate on global patterns of burnt area, fire size, and intensity under Last Glacial Maximum (LGM) conditions using three climate scenarios. Climate change alone did not produce the observed LGM reduction in burnt area, but low CO2 did through reducing vegetation productivity. Fire intensity was sensitive to CO2 but strongly affected by changes in atmospheric dryness. Low CO2 caused smaller fires; climate had the opposite effect except in the driest scenario.

This study evaluates soil carbon projections during the 21st century in CMIP6 Earth system models. In general, we find a reduced spread of changes in global soil carbon in CMIP6 compared to the previous CMIP5 generation. The reduced CMIP6 spread arises from an emergent relationship between soil carbon changes due to change in plant productivity and soil carbon changes due to changes in turnover time. We show that this relationship is consistent with false priming under transient climate change.

Investigations in central and western China show that tree ring inverted latewood intensity expresses a strong positive relationship with growing-season temperatures, indicating exciting potential for regions south of 30° N that are traditionally not targeted for temperature reconstructions. Earlywood BI also shows good potential to reconstruct hydroclimate parameters in some humid areas and will enhance ring-width-based hydroclimate reconstructions in the future.

Here we developed a new burned-area detection algorithm between 2001–2019 across Alaska and Canada at 500 m resolution. We estimate 2.37 Mha burned annually between 2001–2019 over the domain, emitting 79.3 Tg C per year, with a mean combustion rate of 3.13 kg C m−2. We found larger-fire years were generally associated with greater mean combustion. The burned-area and combustion datasets described here can be used for local- to continental-scale applications of boreal fire science.

We propose a new method to quantify carbon cycle feedbacks under negative CO2 emissions. Our method isolates the lagged carbon cycle response to preceding positive emissions from the response to negative emissions. Our findings suggest that feedback parameters calculated with the novel approach are larger than those calculated with the conventional approach whereby carbon cycle inertia is not corrected for, with implications for the effectiveness of carbon dioxide removal in reducing CO2 levels.

A promising strategy for mitigating burdens of heat extremes in Europe is to replace dark coniferous forests with brighter deciduous forests. The consequence of this would be reduced absorption of solar radiation, which should reduce the intensities of heat periods. In this study, we show that deciduous forests have a certain cooling effect on heat period intensities in Europe. However, the magnitude of the temperature reduction is quite small.

Northern soils store a lot of carbon. Most research has focused on how this carbon storage is regulated by cold temperatures. However, it is soil organisms, from minute bacteria to large earthworms, that decompose the organic material. Novel soil organisms from further south could increase decomposition rates more than climate change does and lead to carbon losses. We therefore advocate for including soil organisms when predicting the fate of soil functions in warming northern ecosystems.

Afforestation and reducing fossil fuel emissions are two important mitigation strategies to reduce the amount of global warming. Our work shows that reducing fossil fuel emissions is relatively more effective than afforestation for the same amount of carbon removed from the atmosphere. However, understanding of the processes that govern the biophysical effects of afforestation should be improved before considering our results for climate policy.

CO2 can be stored in the ocean via increasing alkalinity of ocean water. Alkalinity can be created via dissolution of alkaline materials, like limestone or soda. Presented research studies boundaries for increasing alkalinity in seawater. The best way to increase alkalinity was found using an equilibrated solution, for example as produced from reactors. Adding particles for dissolution into seawater on the other hand produces the risk of losing alkalinity and degassing of CO2 to the atmosphere.

Accurate climate models are vital for mitigating climate change; however, projections often disagree. Using Köppen–Geiger bioclimate classifications we show that CMIP6 climate models agree well on the fraction of global land surface that will change classification per degree of global warming. We find that 13 % of land will change climate per degree of warming from 1 to 3 K; thus, stabilising warming at 1.5 rather than 2 K would save over 7.5 million square kilometres from bioclimatic change.

This study provided a synthesis of three influential methods to quantify afforestation impact on surface temperature. Results showed that actual effect following afforestation was highly dependent on afforestation fraction. When full afforestation is assumed, the actual effect approaches the potential effect. We provided evidence the afforestation faction is a key factor in reconciling different methods and emphasized that it should be considered for surface cooling impacts in policy evaluation.

The answer to how much carbon land ecosystems are projected to remove from the atmosphere until 2100 is different for each Earth system model. We find that differences across models are primarily explained by the annual land carbon sink dependence on temperature and soil moisture, followed by the dependence on CO2 air concentration, and by average climate conditions. Our insights on why each model projects a relatively high or low land carbon sink can help to reduce the underlying uncertainty.

Our analysis revealed that under the two most conservative acidification projections foraminifera assemblages did not display considerable changes. However, a significant decrease in species richness was observed when pH decreases to 7.7 pH units, indicating adverse effects under high-acidification scenarios. A micro-CT analysis revealed that calcified tests of Archaias angulatus were of lower density in low pH, suggesting no acclimation capacity for this species.

The standardized vegetation optical depth index (SVODI) can be used to monitor the vegetation condition, such as whether the vegetation is unusually dry or wet. SVODI has global coverage, spans the past 3 decades and is derived from multiple spaceborne passive microwave sensors of that period. SVODI is based on a new probabilistic merging method that allows the merging of normally distributed data even if the data are not gap-free.

Short summary
Lake Ohrid (Macedonia, Albania) is thought to be more than 1.2 million years old. To recover a long paleoclimate record for the Mediterranean region, a deep drilling was carried out in 2013 within the scope of the Scientific Collaboration on Past Speciation Conditions in Lake Ohrid (SCOPSCO) project. Here, we present lithological, sedimentological, and (bio-)geochemical data from the upper 247.8 m composite depth of the overall 569 m long DEEP site record.
Lake Ohrid (Macedonia, Albania) is thought to be more than 1.2 million years old. To recover a...
