We present a reconstruction of permafrost and snow cover on the British Isles for the Younger Dryas period, a time of extremely cold winters that happened approximately 12 000 years ago. Our results indicate that seasonal sea ice in the North Atlantic was most likely a crucial factor to explain the observed climate shifts during this time.

A look at the climate evolution during the last warm period may allow us to test ground for future climate conditions. We quantified the temperature evolution during the Last Interglacial using a tiny amount of water trapped in the crystals of precisely dated stalagmites in caves from the southeastern European Alps. Our record indicates temperatures up to 2 °C warmer than today and an unstable climate during the first half of the Last Interglacial.

This paper utilises a novel palaeoclimate archive from caves, cryogenic cave carbonates, which allow for precisely constraining permafrost thawing events in the past. Our study provides new insights into the climate of the Younger Dryas (12 800 to 11 700 years BP) in mid-Europe from the perspective of a high-elevation cave sensitive to permafrost development. We quantify seasonal temperature and precipitation changes by using a heat conduction model.

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 Neanderthal child. In this study, we present new uranium series ages of stalagmites from the archeological sequence that allow more precise dating of the archeological finds. One key result is that the Neanderthal child may be slightly older than previously thought.

We present in this manuscript a record of temperature changes during the last deglaciation and the Holocene using isotopes of fluid inclusions in stalagmites from the northeastern region of the Iberian Peninsula. This innovative climate proxy for this study region provides a quantitative understanding of the abrupt temperature changes in southern Europe of the last 16500 years before present.

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.

Mechanical damage to stalagmites is commonly observed in mid-latitude caves. In this study we investigate ice flow along the cave bed as a possible mechanism for stalagmite damage. Utilizing models which simulate forces created by ice flow, we study the structural integrity of different stalagmite geometries. Our results suggest that structural failure of stalagmites caused by ice flow is possible, albeit unlikely.

We use multi-proxy speleothem records to reveal a two droughts–one pluvial pattern during 8.5–8.0 ka. The different rebounded rainfall quantity after two droughts causes different behavior of δ13C, suggesting the dominant role of rainfall threshold on the ecosystem. A comparison of different records suggests the prolonged 8.2 ka event is a globally common phenomenon rather than a regional signal. The variability of the AMOC strength is mainly responsible for these climate changes.

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.

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.

We reconstruct the Intertropical Convergence Zone (ITCZ) behavior during the past 3000 years over northeastern Brazil based on oxygen stable isotopes of stalagmites. Paleoclimate changes were mainly forced by the tropical South Atlantic and tropical Pacific sea surface temperature variability. We describe an ITCZ zonal behavior active around 1100 CE and the period from 1500 to 1750 CE. The dataset also records historical droughts that affected modern human population in this area of Brazil.

This study investigates the first finding of fine-grained cryogenic cave minerals in Greenland, a type of speleothem that has been notably difficult to date. We present a successful approach for determining the age of these minerals using 230Th / U disequilibrium and 14C dating. We relate the formation of the cryogenic cave minerals to a well-documented extreme weather event in 1889 CE. Additionally, we provide a detailed report on the mineralogical and isotopic composition of these minerals.

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.

Cryogenic cave carbonates (CCCs) provide a marker for past permafrost conditions. Their formation age is determined by Th / U dating. However, samples can be contaminated with small amounts of Th at formation, which can cause inaccurate ages and require correction. We analysed multiple CCCs and found that varying degrees of contamination can cause an apparent spread of ages, when samples actually formed within distinguishable freezing events. A correction method using isochrons is presented.

We present a thorough analysis of the thermal conditions of a sag-type ice cave in the Austrian Alps using temperature measurements for the period 2008–2021. Apart from a long-term increasing temperature trend in all parts of the cave, we find strong interannual and spatial variations as well as a characteristic seasonal pattern. Increasing temperatures further led to a drastic decrease in cave ice. A first attempt to model ablation based on temperature shows promising results.

The activity of slow-moving deep-seated landslides is commonly governed by pore pressure variations within the shear zone. Groundwater recharge as a consequence of precipitation therefore is a process regulating the activity of landslides. In this context, we present a highly automated geo-statistical approach to spatially assess groundwater recharge controlling the velocity of a deep-seated landslide in Tyrol, Austria.

Stalagmites are valuable climate archives, but unlike other proxies the use of stable carbon isotopes (δ13C) is still difficult. A stalagmite from the Austrian Alps was analyzed using a new laser ablation method for fast radiocarbon (14C) analysis. This allowed 14C and δ13C to be combined, showing that besides soil and bedrock a third source is contributing during periods of warm, wet climate: old organic matter.

In this study, we tested the upper limits of U–Th dating precision by analyzing three stalagmites from the Austrian Alps that have high U concentrations. The composite record spans the penultimate interglacial (MIS 7) with an average 2σ age uncertainty of 400 years. This unprecedented age control allows us to constrain the timing of temperature shifts in the Alps during MIS 7 while offering new insight into millennial-scale changes in the North Atlantic leading up to Terminations III and IIIa.

In this study, we built a statistical model to determine the initial δ234U in submerged calcite crusts that coat the walls of Devils Hole 2 (DH2) cave (Nevada, USA) and, using a 234U–238U dating method, extended the chronology of the calcite deposition beyond previous well-established 230Th ages and determined the oldest calcite deposited in this cave, a time marker for cave genesis. The novel method presented here may be used in future speleothem studies in similar hydrogeological settings.

Tridacna, as the largest marine bivalves, can be used for high-resolution paleoclimate reconstruction in its carbonate skeleton. In this contribution, the modern δ18O shell is suggested to be a proxy for sea surface temperature in the Xisha Islands, South China Sea. Data from a fossil Tridacna (3673 ± 28 BP) indicate a warmer climate and intense ENSO-related variability but reduced ENSO frequency and more extreme El Niño winters compared to modern Tridacna.

Few studies have paid attention to the important effect of nonsummer monsoon (NSM) precipitation on the speleothem δ18O in SE China. We find the summer monsoon precipitation is equivalent to NSM precipitation amount in the area of spring persistent rain in SE China, and we discuss the relationships between seasonal precipitation amount, moisture source, δ18O, and ENSO. Characterizing the spatial differences in seasonal precipitation is key to interpreting the speleothem δ18O record.

Abrupt climate change during the last ice age can be used to provide important insights into the timescales on which the climate is capable of changing and the mechanisms that drive those changes. In this study, we construct climate records for the period 60 to 120 ka using stalagmites that formed in caves along the northern rim of the European Alps and find good agreement with the timing of climate changes in Greenland and the Asian monsoon.

Rainfall in North Africa is known to vary through time and is likely to change as global climate warms. Here, we provide a new level of understanding about past rainfall in North Africa by looking at a stalagmite which formed within northeastern Libya between 67 and 30 thousand years ago. We find that at times more rain falls, and the associated moisture is mostly derived from the western Mediterranean during winter storms. Sometimes, water comes from the eastern Mediterranean.

The
4.2 ka eventbetween 4.2 and 3.9 ka has been widely discussed in the Northern Hemsiphere but less reported in the Southern Hemisphere. Here, we use speleothem records from Rodrigues in the southwestern Indian Ocean spanning from 6000 to 3000 years ago to investigate the regional hydro-climatic variability. Our records show no evidence for an unusual climate anomaly between 4.2 and 3.9 ka. Instead, it shows a multi-centennial drought between 3.9 and 3.5 ka.

The 4.2 ka event is generally characterized as an approximately 300-year period of major global climate anomaly. However, the climatic manifestation of this event remains unclear in the Indian monsoon domain. Our high-resolution and precisely dated speleothem record from Meghalaya, India, characterizes the event as consisting of a series of multi-decadal droughts between 3.9 and 4.0 ka rather than a singular pulse of multi-centennial drought as previously thought.

The collapses of several Neolithic cultures in China are considered to have been associated with abrupt climate change during the 4.2 ka BP event; however, the hydroclimate of this event in China is still poorly known. Based on stalagmite records from monsoonal China, we found that north China was dry but south China was wet during this event. We propose that the rain belt remained longer at its southern position, giving rise to a pronounced humidity gradient between north and south China.

The last glacial period was characterized by a number of rapid climate changes seen, for example, as abrupt warmings in Greenland and changes in monsoon rainfall intensity. However, due to chronological uncertainties it is challenging to know how tightly coupled these changes were. Here we exploit cosmogenic signals caused by changes in the Sun and Earth magnetic fields to link different climate archives and improve our understanding of the dynamics of abrupt climate change.

This research has been an investigation of two stalagmites from two caves in NW Madagascar to reconstruct the region's paleoenvironmental changes, and to understand the linkage of such changes to the dynamics of the ITCZ. Stable isotopes, mineralogy, and petrography suggest wetter climate conditions than today during the early and late Holocene, when the mean ITCZ was south, and drier during the mid-Holocene when the ITCZ was north.

The use of stalagmites for last interglacial continental climate reconstructions in Europe has been successful in the past; however to expand the geographical coverage, additional data from Belgium is presented. It has been shown that stalagmite growth, morphology and stable isotope content reflect regional and local climate conditions, with Eemian optimum climate occurring between 125.3 and 117.3 ka. The start the Weichselian is expressed by a stop of growth caused by a drying climate.

The main aim of this paper is to present the summer vapor pressure deficit (VPD) reconstruction dataset for the last 400 years over Europe based on δ18O records by using a random forest approach. 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. We attribute variability in temperature-limited trees to strong volcanic eruptions and for the first time detect a spatial pattern in the growth of moisture-sensitive trees after eruptions.

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.

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.

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.

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.

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.

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.

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.

Short summary
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.
