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 EU Knowledge Hub on Sea Level Rise’s Assessment Report strives to synthesize the current scientific knowledge on sea level rise and its impacts across local, national, and EU scales to support evidence-based policy and decision-making, primarily targeting coastal areas. This paper complements IPCC reports by documenting the state of knowledge of observed and 21st century projected changes in mean and extreme sea levels with more regional information for EU seas as scoped with stakeholders.

Sea level rise has major impacts in Europe, which vary from place to place and in time, depending on the source of the impacts. Flooding, erosion, and saltwater intrusion lead, via different pathways, to various consequences for coastal regions across Europe. This causes damage to assets, the environment, and people for all three categories of impacts discussed in this paper. The paper provides an overview of the various impacts in Europe.

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.

We present the geophysical data set acquired close to Ny-Ålesund (Svalbard islands) for the characterization of glacial and hydrological processes and features. The data have been organized in a repository that includes both raw and processed (filtered) data and some representative results of 2D models of the subsurface. This data set can foster multidisciplinary scientific collaborations among many disciplines: hydrology, glaciology, climatology, geology, geomorphology, etc.

The sedimentary sequence in Scladina Cave (Belgium) is well-known for its rich archeological assemblages and its numerous faunal remains. Of particular interest is the presence of a nearly complete jaw bone of a Neandertal child. In this study, we present new Uranium-series ages of stalagmites from the archeological sequence which allow more precise dating of the archeological finds. One key result is that the Neandertal child may be slightly older than previously thought.

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.

Lead (Pb) isotopes form a potent tracer in studies of provenance, mineral exploration and environmental remediation. Previously, however, Pb isotope analysis has rarely been deployed at a continental scale. Here we present a new regolith Pb isotope dataset for Australia, which includes 1119 large catchments encompassing 5.6 × 106 km2 or close to ~75 % of the continent. Isoscape maps have been produced for use in diverse fields of study.

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 Paleochrono1 probablistic dating model allows 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) Delta-depth observations. Paleochrono1 is available under the MIT open-source license.

Cyclone detection and tracking methods (CDTMs) have different approaches in defining and tracking cyclone centers. This leads to disagreements on extratropical cyclone climatologies. We present a new approach that combines tracks from individual CDTMs to produce new composite tracks. These new tracks are shown to correspond to physically meaningful systems with distinctive life stages.

Tornadoes represent disruptive and dangerous weather events. The prediction of these small-scale phenomena depends on the resolution of present weather forecast and climatic projections. This work discusses the occurrence of tornadoes in terms of atmospheric variables and provides analytical expressions for their conditional probability. These formulas represent a tool for tornado alert systems and for estimating the future evolution of tornado frequency and intensity in climate projections.

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.

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.

We provide a ca. 1000 year long (6.4–5.4 ka BP) stalagmite-based reconstruction of mid-Holocene rainfall variability in the tropical western Pacific. The annually laminated multi-proxy (δ13C, δ18O, X/Ca, gray values) record comes from Niue island and informs on El Nino-Southern Oscillation and South Pacific Convergence Zone dynamics. Our data suggest that ENSO was active and influenced rainfall seasonality over the covered time interval. Rainfall seasonality was subdued during active ENSO phases

Relative sea level in Venice rose by about 2.5 mm/year in the past 150 years due to the combined effect of subsidence and mean sea-level rise. We estimate the likely range of mean sea-level rise in Venice by 2100 due to climate changes to be between about 10 and 110 cm, with an improbable yet possible high-end scenario of about 170 cm. Projections of subsidence are not available, but historical evidence demonstrates that they can increase the hazard posed by climatically induced sea-level rise.

In this review we describe the factors leading to the extreme water heights producing the floods of Venice. We discuss the different contributions, their relative importance, and the resulting compound events. We highlight the role of relative sea level rise and the observed past and very likely future increase in extreme water heights, showing that they might be up to 160 % higher at the end of the 21st century than presently.

The city of Venice relies crucially on a good storm surge forecast to protect its population and cultural heritage. In this paper, we provide a state-of-the-art review of storm surge forecasting, starting from examples in Europe and focusing on the Adriatic Sea and the Lagoon of Venice. We discuss the physics of storm surge, as well as the particular aspects of Venice and new techniques in storm surge modeling. We also give recommendations on what a future forecasting system should look like.

Venice is an iconic place, and a paradigm of huge historical and cultural value is at risk. The threat posed by floods has dramatically increased in recent decades and is expected to continue to grow – and even accelerate – through this century. There is a need to better understand the future evolution of the relative sea level and its extremes and to develop adaptive planning strategies appropriate for present uncertainty, which might not be substantially reduced in the near future.

We analyzed lignin oxidation products (LOPs) in leaf litter and different soil horizons as well as dripwater and flowstone samples from four different cave sites from different vegetation zones in New Zealand using liquid chromatography coupled to mass spectrometry. We test whether the original source-dependent LOP signal of the overlying vegetation is preserved and can be recovered from flowstone samples and investigate how the signal is altered by the transport from the soil to the cave.

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.

The standard approach to isochron calculation assumes that the distribution of uncertainties on the data arising from isotopic analysis is strictly Gaussian. This excludes datasets that have more scatter, even though many appear to have age significance. Our new approach requires only that the central part of the uncertainty distribution of the data defines a "spine" in the trend of the data. A robust statistics approach is used to locate the spine, and an implementation in Python is given.

Speleothems are powerful archives of past climate for understanding modern local hydrology and its relation to regional circulation patterns. We use a 3-year monitoring dataset to test the sensitivity of Waipuna Cave to seasonal changes and El Niño–Southern Oscillation (ENSO) dynamics. Drip water data suggest a fast response to rainfall events; its elemental composition reflects a seasonal cycle and ENSO variability. Waipuna Cave speleothems have a high potential for past ENSO reconstructions.

Recently developed methods for in situ U–Pb age determination in carbonates have found widespread application, but the benefits and limitations of the method over bulk analysis approaches have yet to be fully explored. Here we use speleothems – cave carbonates such as stalagmites and flowstones – to investigate the utility of these in situ dating methodologies for challenging matrices with low U and Pb contents and predominantly late Cenozoic ages.

Large positive and negative sea level anomalies on the coast of the Mediterranean Sea are produced by cyclones moving along the Mediterranean storm track, which are mostly generated in the western Mediterranean. The wind around the cyclone center is the main cause of sea level anomalies when a shallow water fetch is present. The inverse barometer effect produces a positive anomaly near the cyclone pressure minimum and a negative anomaly at the opposite side of the Mediterranean Sea.

This paper uses colocated observations of temperature, precipitation and humidity to investigate the triggering of precipitation. It shows that there is a critical value of humidity above which precipitation picks up. This critical value depends on T and varies spatially. It also analyses how this dependency is reproduced in regional climate simulations over Europe. Models with too little and too light precipitation have both lower critical value of humidity and higher probability to exceed it.

The penultimate deglaciation (~ 138–128 ka), which represents the transition into the Last Interglacial period, provides a framework to investigate the climate and environmental response to large changes in boundary conditions. Here, as part of the PAGES-PMIP working group on Quaternary Interglacials, we propose a protocol to perform transient simulations of the penultimate deglaciation as well as a selection of paleo records for upcoming model-data comparisons.

Existing sedimentary palaeoclimate records in Australasia were assessed for suitability for examining the last 2 millennia. A small number of high-quality records were identified, and new Bayesian age models were constructed for each record. Findings suggest that Australasian record chronologies and confidence in proxy–climate relationships are the main factors limiting appropriate data for examining Common Era climate variability. Recommendations for improving data accessibility are provided.

Little is known about the climate of southern Australia during the Last Glacial Maximum and deglaciation owing to sparse records for this region. We present the first high-resolution data, derived from speleothems that grew 23–5 ka. It appears that recharge to the Flinders Ranges was higher than today, particularly during 18.9–15.8 ka, argued to be due to the enhanced availability of tropical moisture. An abrupt shift to aridity is recorded at 15.8 ka, associated with restored westerly airflow.

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.

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.

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.

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.

We provide both a spatial and a temporal long-term perspective on the past summer VPD and new insights into the relationship between summer VPD and large-scale atmospheric circulation. This is the first gridded reconstruction of the European summer VPD over the past 400 years.

We reconstructed the monthly mean self-calibrating Palmer drought severity index for May–July in the upper Heilongjiang (Amur) Basin since 1796. Our analysis suggests that the dry/wet variability in this basin is related to several large-scale climate stresses and atmospheric circulation patterns (El Niño–Southern Oscillation). The cause of drought is primarily a reduction in advective water vapor transport, rather than precipitation circulation processes.

In this study, we develop the first tree-ring-based precipitation reconstruction for the northern South American Altiplano back to 1625 CE. We established that the occurrence rate of extreme dry events together with a shift in mean dry conditions for the late 20th–beginning of the 21st century is unprecedented in the past 389 years, consistent with other paleoclimatic records. Our reconstruction provides valuable information about El Niño–Southern Oscillation influences on local precipitation.

Detection and attribution is a statistical method to evaluate if external factors or random variability have caused climatic changes. We use for the first time a comparison of simulated and observed tree-ring width that circumvents many limitations of previous studies relying on climate reconstructions.

Plant wax lipid ratios and their isotopes are used in vegetation and paleoclimate reconstructions. While studies often use either type of data, both can inform the mixing pattern of source plants. We developed a statistic model that evaluates ratios and isotopes together. Through case studies, we showed that the approach allows more detailed interpretations of vegetation and paleoclimate than traditional methods. This evolving framework can include more geochemical tracers in the future.

We studied eight New Zealand tree species and identified differences in their responses to large volcanic eruptions. The response is dependent on the species and how well it can tolerate stress, but substantial within-species differences are also observed depending on site factors, including altitude and exposure. This has important implications for tree-ring temperature reconstructions because site selection and compositing methods can change the magnitude of observed volcanic cooling.

In general, it is not easy to reconstruct past climate variations over a wide band of frequencies using a single proxy. Here, we propose a new method to reconstruct past summer climate seamlessly from annual to millennial timescales by integrating tree-ring cellulose oxygen and hydrogen isotope ratios.

Climatic reconstructions based on tree-ring isotopic series convey key information on past conditions prevailing in forested regions. However, in some cases, the relations between isotopes and climate appear unstable over time, generating isotopic divergences. Former reviews have thoroughly discussed the divergence concept for tree-ring width but not for isotopes. Here we present a synopsis of the isotopic divergence problem and suggest collaborative work for improving climatic reconstructions.

One can use the similarity between sparse indirect observations of past climates and full fields of simulated climates to learn more about past climates. Here, we detail how one can compute uncertainty estimates for such reconstructions of past climates. This highlights the ambiguity of the reconstruction.

We measured biomarker production over a year in a small inland lake in the northeastern USA. Understanding biomarkers in the modern environment helps us improve reconstructions of past climate from lake sediment records. We use these results to interpret a 900-year decadally resolved temperature record from this lake. Our record highlights multi-decadal oscillations in temperature superimposed on a long-term cooling trend, providing novel insight into climate dynamics of the region.

Abundances of plant biomarkers are compared with pollen data in a 3000-year climate archive covering the Late Glacial to Holocene transition in northern Poland. Both parameters synchronously show the rapid onset (12680–12600 yr BP) and termination
(11580–11490 yr BP) of the Younger Dryas cold interval in the study area. This demonstrates the suitability of such proxies to record pronounced changes in vegetation cover without significant delay.

The reconstruction of ground surface temperature for the last 500 years, obtained at the deepest mountain permafrost borehole of the world (Stelvio Pass, 3000 m a.s.l., Italian Alps), is presented here. The main difference with respect to MAAT reconstructions obtained through other proxy data for all of Europe relates to post Little Ice Age (LIA) events. Indeed at this site a stronger cooling of ca 1 °C between 1940 and 1989 and even a more abrupt warming between 1990 and 2011 was detected.

We have constructed a regional tree ring cellulose oxygen isotope record using a total of five chronologies obtained from the Himalaya. Centennial changes in the regional tree ring record indicate a trend of weakened Indian summer monsoon (ISM) intensity since 1820. Decreasing ISM activity is also observed in various high-resolution ISM records from southwest China and Southeast Asia, and may be the result of reduced land–ocean thermal contrasts since 1820.

We compiled 31 temperature–depth profiles to reconstruct the ground surface temperature of the last 500 years in northern Chile. They suggest that the region experienced a cooling from 1850 to 1980 followed by a warming of 1.9 K. The cooling could coincide with a cooling interval in 1960. The warming is greater than that of proxy reconstructions for nearby regions and model simulations. These differences could be due to differences in spatial and temporal resolution between data and models.

We present a new gridded Arctic summer temperature reconstruction back to the first millennium CE. Our method respects the age uncertainties of the data, which results in a more precise reconstruction.
The spatial average shows a millennium-scale cooling trend which is reversed in the mid-19th century. While temperatures in the 10th century were probably as warm as in the 20th century, the spatial coherence of the recent warm episodes seems unprecedented.

Here we present a multi-proxy study of flowstones in fractures of crystalline rocks with the aim of assessing the palaeoclimate significance of this new type of speleothem archive. Our results indicate a high degree of spatial heterogeneity, whereby changes in speleothem mineralogy and carbon isotope composition are likely governed by aquifer-internal processes. In contrast, the oxygen isotope composition reflects first-order climate variability.

Water availability is fundamental to societies and ecosystems, but our understanding of variations in hydroclimate (including extreme events, flooding, and decadal periods of drought) is limited due to a paucity of modern instrumental observations. We review how proxy records of past climate and climate model simulations can be used in tandem to understand hydroclimate variability over the last 2000 years and how these tools can also inform risk assessments of future hydroclimatic extremes.

We analyze a tree-ring network from several sites distributed along the Italian Peninsula with the aims of detecting common climate drivers of tree growth and of reconstructing the past climate. We detect the main climatic drivers modulating tree-ring width (RW) and tree-ring maximum latewood density (MXD) and we reconstruct late summer temperatures since the early 1700s using a MXD chronology: this reconstruction is representative of a wide area around the Italian Peninsula.

Existing sedimentary palaeoclimate records in Australasia were assessed for suitability for examining the last 2 millennia. A small number of high-quality records were identified, and new Bayesian age models were constructed for each record. Findings suggest that Australasian record chronologies and confidence in proxy–climate relationships are the main factors limiting appropriate data for examining Common Era climate variability. Recommendations for improving data accessibility are provided.

To improve our understanding of paleoclimate in the northeastern (NE) US, we compiled data from pollen, tree rings, lake levels, testate amoeba from bogs, and other proxies from the last 3000 years. The paleoclimate synthesis supports long-term cooling until the 1800s and reveals an abrupt transition from wet to dry conditions around 550–750 CE. Evidence suggests the region is now becoming warmer and wetter, but more calibrated data are needed, especially to capture multidecadal variability.

Blue intensity shows great potential for reconstructing past summer temperatures from conifer trees growing at high latitude or the treeline. However, conifer species that express a strong colour difference between the heartwood and sapwood can impart a long-term trend bias in the resultant reconstructions. Herein, we highlight this issue using eight mountain hemlock sites across the Gulf of Alaska and explore how a non-biased reconstruction of past temperature could be derived using such data.

El Niño-Southern Oscillation (ENSO) is linked to severe droughts and floods in mainland Southeast Asia. This research provides a more accurate and uniform picture of the spatio-temporal effects of ENSO on precipitation (1980–2013) and improves our understanding of long-term (1650–2004) ENSO teleconnection and its variability over the study area. The results reveal not only recognisable spatio-temporal patterns but also a high degree of variability and non-stationarity in the effects of ENSO.

A new data set of 3194 oak (Quercus spp.) ring width samples collected across the Czech Republic and covering the past 1250 years was analysed. The temporal distribution of negative and positive TRW extremes occurring is regular with no indication of clustering. Negative TRW extremes coincided with above-average March-May and June-August temperature means and below-average precipitation totals. Positive extremes coincided with higher summer precipitation, while temperatures were mostly normal.

A 601-year lake area reconstruction in NW Argentina and SW Bolivia, characterized the occurrence of annual to multi-decadal lake area fluctuations and its main oscillation modes of variability. Our reconstruction points out that the late 20th century decrease in lake area was exceptional over the period 1407–2007. A persistent negative trend in lake area is clear in the reconstruction and consistent with glacier retreat and other climate proxies from the Altiplano and the tropical Andes.

A new approach to time series analysis - the ORR method - was used to evaluate reconstructed western US streamflow records during 1500-2007. This method shows an interesting pattern of alternating drought and wet periods during the late 16th and 17th centuries, a period with relatively few drought or wet periods during the 18th century, and the and the reappearance of alternating dry and wet periods during the 19th and early 20th centuries.

Short summary
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.
To understand the natural variability in the climate system, the hydrological aspect (dry and...
