To better understand and contextualize modern climate change, this systematic review synthesizes climate and oceanographic patterns in the Western United States and California Current System through the most recent 11.75 kyr. Through a literature review and coded analysis of past studies, we identify distinct environmental phases through time and linkages between marine and terrestrial systems. We explore climate change impacts on ecosystems and human–environment interactions.

To look at climate over the past 12 000 years, we reconstruct spatial temperature using natural climate archives and information from model simulations. Our results show mild global mean warmth around 6000 years ago, which differs somewhat from past reconstructions. Undiagnosed seasonal biases in the data could explain some of the observed temperature change, but this still would not explain the large difference between many reconstructions and climate models over this period.

We investigated the diversity of algae called diatoms in Lake Baikal, the oldest and deepest lake in the world, because algae sit at the base of aquatic foodwebs and provide energy (in the form of primary production) for other organisms to use. Diatom diversity and primary production have been influenced by both long-term and abrupt climate change over the past 16 000 years. The shape of these responses appears to be time-period specific.

We reconstructed the Holocene climates in Iberian Peninsula using a large pollen dataset and found that the west-east moisture gradient was much flatter than today. We also found that the winter was much colder, which can be expected from the low winter insolation during the Holocene. However, summer temperature didn’t follow the trend of summer insolation, instead, it was strongly correlated with moisture.

We created a residual tree-ring width chronology and reconstructed non-growth-season precipitation (NGSP) over the period spanning 1600–2005 in the southeastern Tibetan Plateau (SETP), China. Reconstruction model verification as well as similar variations of NGSP reconstruction and Palmer Drought Severity Index reconstructions from the surrounding region indicate the reliability of the present reconstruction. Our reconstruction is representative of NGSP variability of a large region in the SETP.

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.

We present a reconstruction of winter–spring temperatures developed using organic proxies preserved in well-dated lake sediments from southwest Iceland to assess seasonal temperature changes in the North Atlantic region over the last 2000 years. The gradual warming trend observed in our record is likely influenced by sea surface temperatures, which are sensitive to changes in ocean circulation and seasonal insolation, during the winter and spring season.

Since the understanding of Holocene climate change appears to be a relevant issue for future climate change, the paleoclimate calibrations have to be improved. Here, surface samples from Mongolia and Siberia were analyzed to provide new calibrations for pollen and biomarker climate models. These calibrations appear to be more powerful than global calibrations, especially in an arid central Asian context. These calibrations will improve the understanding of monsoon Holocene oscillations.

We found that increasing the density of chronologies in the tree-ring network resulted in estimated soil moisture conditions that better matched the spatial variability of the values that were instrumentally recorded for droughts and, to a lesser extent, pluvials. By sampling trees in 2010 compared to 1980, the sensitivity of tree rings to soil moisture decreased in the southern portion of our region, where severe drought conditions have been absent over recent decades.

In an attempt to consolidate trends in the hydrological cycle induced by recent warming, we conducted a multidisciplinary study combining meteorological data, climate proxies from the literature, and original coring and pollen data acquired in an area that has been hit by record-breaking precipitation events. A detailed study of recent flash-flood deposits compared with fossil peat bog and lake sediments supports the expected increase in precipitation intensity during warm climatic phases.

The Qinling mountains in China are biodiversity rich. We studied one of the high-latitude lakes on Mount Taibai with a view to looking at how aquatic diversity responded to long-term changes in climate over the past 3500 years. We specifically looked at a group of single-celled algae called diatoms, as they are very sensitive to the environment. We found that these algae changed gradually over time, but they showed abrupt change during the period known as the Little Ice Age, about 400 years ago.

The East Asian summer monsoon and winter monsoon are anticorrelated on a centennial timescale during 16–1 ka. The centennial monsoon variability is connected to changes of both solar activity and North Atlantic cooling events during the Early Holocene. Then, North Atlantic cooling became the major forcing of events during the Late Holocene. This work presents the great challenge and potential to understand the response of the monsoon system to global climate changes in the past and the future.

In this paper we identify warming thresholds, rates, and forcing mechanisms from a novel alpine temperature record of the southern Iberian Peninsula during the Common Era in order to contextualize the modern warming and its potential impact on these vulnerable alpine ecosystems. To do so, we have developed and applied the first lacustrine temperature calibration in alpine lakes for algal compounds, called long-chain alkyl diols, which is a significant advance in biomarker paleothermometry.

We measured the chemical composition (trace-element concentrations and stable-isotope ratios) of a Belgian speleothem that deposited annual layers. Our sub-annual resolution dataset allows us to investigate how the chemistry of this speleothem recorded changes in the environment and climate in northwestern Europe. We then use this information to reconstruct climate change during the 16th and 17th century on the seasonal scale and demonstrate that environmental change drives speleothem chemistry.

With the use of precipitation sensitive oak ring-width series from the Main River region (southern Germany) a 2000-year long hydroclimate reconstruction has been developed. The ring series are sensitive to the sum of rainfall from 26 February to 6 July. This region suffered from severe, long-lasting droughts in the past two millennia (e.g., AD 500/510s, 940s, 1170s, 1390s and 1160s). In the AD 550s, 1050s, 1310s and 1480s, multi-year periods with high rainfall hit the region.

A new method for probabilistic spatial reconstructions of past climate states is presented, which combines pollen data with a multi-model ensemble of climate simulations in a Bayesian framework. The approach is applied to reconstruct summer and winter temperature in Europe during the mid-Holocene. Our reconstructions account for multiple sources of uncertainty and are well suited for quantitative statistical analyses of the climate under different forcing conditions.

This is the first quantitative study of lignin biomarkers in stalagmites and cave drip water. Lignin is only produced by higher plants; therefore, its analysis can be used to reconstruct the vegetation of the past. We compared our lignin results with stable isotope and trace element records from the same samples and found correlations or similarities with P, Ba, U and Mg concentrations as well as δ13C values. These results can help to better interpret other vegetation proxies.

We present a unique dataset of multiple tree-ring and stable isotope parameters, representing temperature-sensitive Siberian ecotones, to assess climatic impacts after six large stratospheric volcanic eruptions at 535, 540, 1257, 1640, 1815, and 1991 CE. Besides the well-documented effects of temperature derived from tree-ring width and latewood density, stable carbon and oxygen isotopes in tree-ring cellulose provide information about moisture and sunshine duration changes after the events.

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.

Compositing climate proxies in sediment from seven Iceland lakes documents abrupt summer cooling between 4.5 and 4.0 ka, statistically indistinguishable from 4.2 ka. Although the decline in summer insolation was an important factor, a combination of superposed changes in ocean circulation and explosive Icelandic volcanism were likely responsible for the abrupt perturbation recorded by our proxies. Lake and catchment proxies recovered to a colder equilibrium state following the perturbation.

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.

Holocene fires and vegetation are reconstructed using different molecular markers with a single analytical method, applied for the first time to lake sediments from Tibet. The early Holocene shows oscillations between grasses and conifers, with smouldering fires represented by levoglucosan peaks, and high-temperature fires represented by PAHs. The lack of human FeSts excludes local human influence on fire and vegetation changes. Late Holocene displays an increase in local to regional combustion.

We explain the procedure used to attain a high and consistent level of data stewardship across a special issue of the journal Climate of the Past. We discuss the challenges related to (1) determining which data are essential for public archival, (2) using data generated by others, and (3) understanding data citations. We anticipate that open-data sharing in paleo sciences will accelerate as the advantages become more evident and as practices that reduce data loss become the accepted convention.

The chironomid-inferred temperature record from Gonghai Lake exhibits a stepwise decreasing trend since 4 ka. A cold event in the Era of Disunity, the Sui-Tang Warm Period, the Medieval Warm Period and the Little Ice Age can all be recognized in our record, as well as in many other temperature reconstructions in China. Local wars in Shanxi Province, documented in the historical literature during the past 2700 years, are statistically significantly correlated with changes in temperature.

The Atlantic Multidecadal Oscillation (AMO) is prominent in the climate system. We study the AMO over the last 2000 years using a novel proxy framework, the Last Millennium Reanalysis. We find that the AMO is linked to continental warming, Arctic sea ice retreat, and an Atlantic precipitation shift. Low clouds decrease globally. We find no distinct multidecadal spectral peak in the AMO over the last 2 millennia, suggesting that human activities may have enhanced the AMO in the modern era.

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.

Pollen-based past climate reconstruction for regions with long-term human occupation is always controversial. We examined the bias induced by the human impact on vegetation in a climate reconstruction for temperate eastern China by comparing the deviations in the reconstructed results for a fossil record based on two pollen–climate calibration sets. Climatic signals in pollen assemblages are indeed obscured by human impact; however, the extent of the bias could be assessed.

Currently, reconstructions of past changes in the hydrological cycle are usually qualitative, which is a major drawback for testing the accuracy of models in predicting future responses. Here we present a proof of concept of a novel approach to deriving quantitative paleohydrological data, i.e. changes in relative humidity, from lacustrine sediment archives, employing a combination of organic geochemical methods and plant physiological modeling.

This contribution aims at assessing to what extent the analogue method, a classic technique used in other branches of meteorology and climatology, can be used to perform gridded reconstructions of annual temperature based on the limited information from available but un-calibrated proxies spread across different locations of the world. We conclude that it is indeed possible, albeit with certain limitations that render the method comparable to more classic techniques.

Data assimilation has been successfully applied in the field of paleoclimatology to reconstruct past climate. However, data reconstructed from proxies have been assimilated, as opposed to the actual proxy values, which prevented full utilization of the information recorded in the proxies. This study propose a new data assimilation system in which actual proxy data are directly assimilated.

This paper reports the first development of sub-fossil chironomid-based mean July temperature transfer functions from China. The transfer functions yield reliable reconstructions that are comparable to the instrumental record. The application of this new tool will provide long-term quantitative palaeoclimate estimates from south-western China which is a critical region for understanding the dynamic and evolution of the Indian Ocean south-west Monsoon system.

Indirect evidence on past climate comes from the former composition of ecological communities such as plants, preserved as pollen grains in sediments of lakes. Transfer functions convert relative counts of species to a climatologically meaningful scale (e.g. annual mean temperature in degrees C). We show that the fundamental assumptions in the algorithms impact the reconstruction results in he idealized model world, in particular if the reconstructed variables were not ecologically relevant.

The fossilized seeds of common millet are suited to the production of quantitative Holocene precipitation reconstructions. Our reconstructed results showed that summer precipitation from 7.7–3.4 ka BP was ~ 50 mm, or 17 % higher than present levels. Maximal mean summer precipitation peaked at 414 mm during 6.1–5.5 ka BP, ~ 109 mm, or 36 % higher than today, indicating the EASM peaked at this time. This work can provide a new proxy for further research into continuous paleoprecipitation sequences.

This study investigates the NAO (Northern Atlantic Oscillation)-related mechanisms that control winter precipitation stable oxygen and hydrogen isotope gradients across Europe. The results show that past longitudinal stable oxygen and hydrogen isotope gradients in European rainfall stored in palaeoclimate archives (e.g. speleothems) can be used to infer the past winter NAO modes from its variations.

We present a 368-year late summer maximum temperature reconstruction based on spruce tree rings. It touches on the critical topic of climate reconstruction in the eastern edge of Tibetan Plateau and represents an extension and enhancement of climate records for this area. The Little Ice Age was well represented and 20th century warming was not obvious in this reconstruction. This temperature variation may be affected by global land–sea atmospheric circulation as well as solar and volcanic forcing.

Chironomidae are a family of two-winged aquatic fly of the order Diptera. The family is species rich (> 5000 described species) and extremely sensitive to environmental change, particualy temperature. Across the Northern Hemisphere, chironomids have been widely used as paleotemperature proxies as the chitinous remains of the insect are readily preserved in lake sediments. This is the first study using chironomids as paleotemperature proxies in tropical South America.

Cushion peatlands are versatile climate archives for the study of past environmental changes. We present the environmental history for the last 2100 years of Cerro Tuzgle peatland, which is located in the NW Argentine Puna. The results reflect prominent late Holocene climate anomalies and provide evidence that Northern Hemisphere climate oscillations were extensive. Volcanic forcing at the beginning of the 19th century seems to have had an impact on climatic settings in the Central Andes

The lack of accepted data formats and data standards in paleoclimatology is a growing problem that slows progress in the field. Here, we propose a preliminary data standard for paleoclimate data, general enough to accommodate all the proxy and measurement types encountered in a large international collaboration (PAGES 2k). We also introduce a data format for such structured data (Linked Paleo Data, or LiPD), leveraging recent advances in knowledge representation (Linked Open Data).

We propose a Bayesian model for the reconstruction and analysis of former sea levels. The model provides a single, unifying framework for reconstructing and analyzing sea level through time with fully quantified uncertainty. We illustrate our approach using a case study of Common Era (last 2000 years) sea levels from New Jersey.

Ignoring nonlinearity in palaeoclimate records (e.g. continental run-off proxies) runs the risk of severely overstating changes in climate variability. Even with the correct model and parameters, some information is irretrievably lost by such proxies. However, we find that a simple empirical transform can do much to improve the situation, and makes them amenable to classical analyses. Doing so on two palaeo-ENSO records markedly changes some of the quantitative inferences made from such records.

Fluid inclusions inside stalagmites retain information on the cave temperature at the time they formed and thus can be used to reconstruct the continental climate of the past. A method for extracting this information based on a thermodynamic model and size measurements of femtosecond-laser-induced vapour bubbles is presented. Applying our method to stalagmites taken from the Milandre cave in the Swiss Jura Mountains demonstrate that palaeotemperatures can be determined with an accuracy of ±1°C.
