This paper provides an initial exploration and comparison to climate reconstructions of the new climate model simulations of the mid-Holocene (6000 years ago). These use state-of-the-art models developed for CMIP6 and apply the same experimental set-up. The models capture several key aspects of the climate, but some persistent issues remain.

Rapid climate warming is impacting physical processes in Arctic environments. Glacier–fed lakes are influenced by many of these processes, and they are impacted by the changing behavior of weather, glaciers, and rivers. We present data from weather stations, river gauging stations, lake moorings, and more, following 4 years of environmental monitoring in the watershed of Lake Peters, a glacier–fed lake in Arctic Alaska. These data can help us study the changing dynamics of this remote setting.

A synthesis of 93 published records reveals that moisture availability increased over large portions of North America over the past 2000 years, the Common Era (CE). In many records, the second millennium CE tended to be wetter than the first millennium CE. The long-term changes formed the background for annual to multi-decade variations, such as "mega-droughts", and also provide a context for amplified rates of hydrologic change today.

Root zone storage capacity (Sumax) changes significantly over multiple decades, reflecting vegetation adaptation to climatic variability. However, this temporal evolution of Sumax cannot explain long-term fluctuations in the partitioning of water fluxes as expressed by deviations ΔIE from the parametric Budyko curve over time with different climatic conditions, and it does not have any significant effects on shorter-term hydrological response characteristics of the upper Neckar catchment.

This research examines how future climate changes impact root zone storage, a crucial hydrological model parameter. Root zone storage—the soil water accessible to plants—adapts to climate but is often treated as constant in models. We estimated climate-adapted storage for six Austrian Alps catchments. Although storage increased, streamflow projections showed minimal change, indicating that dynamic root zone representation is less critical in humid regions but warrants more study in arid areas.

Here we present summer snowline altitude (SLA) time series for 269 Arctic glaciers. Between 1984 and 2022, SLAs rose ∼ 150 m, equating to a ∼ 127 m shift per 1 °C of summer warming. SLA is most strongly correlated with annual temperature variables, highlighting their dual effect on ablation and accumulation processes. We show that SLAs are rising fastest on low-elevation glaciers and that > 50 % of the studied glaciers could have SLAs that exceed the maximum ice elevation by 2100.

A gap in understanding climate variation exists at centennial to millennial scales, particularly for warm climates. Such variations challenge detection. They exceed direct observation but are geologically short. Centennial to millennial variations that may have influenced North America were examined over the past 7 kyr. Significant patterns were detected from fossil pollen and sedimentary lake level changes, indicating ecological, hydrological, and likely human significance.

Few tropical Hg records extend beyond ~12 ka, meaning our current understanding of Hg behaviour may not fully account for the impact of long-term hydroclimate changes on the Hg cycle in these environments. Here, we present a ~96,000-year Hg record from Lake Bosumtwi, Ghana. A coupled response is observed between Hg flux and shifts in sediment composition reflective of changes in lake level, and suggesting that hydroclimate may be a key driver of tropical Hg cycling over millennial-timescales.

We reconstruct global hydroclimate anomalies for the past 21,000 years using a data assimilation methodology blending observations recorded in lake sediments with the climate dynamics simulated by climate models. The reconstruction resolves data-model disagreement in East Africa and North America, and we find that changing global temperatures and associated circulation patterns as well as orbital forcing are the dominant controls on global precipitation over this interval.

This study investigated how the deposition of mineral dust delivered by the wind influences soil development in mountain environments. At six mountain locations in the southwestern United States, modern dust was collected along with samples of soil and local bedrock. Analysis indicates that at all sites the properties of dust and soil are very similar and are very different from underlying rock. This result indicates that soils are predominantly composed of dust delivered by the wind over time.

Holocene vegetation-atmosphere interactions provide insight into intensifying land use impacts and the Holocene Conundrum- a mismatch between data- and model- inferred temperature. Using pollen records and statistical modeling, we reconstruct Holocene land cover for North America. We determine patterns and magnitudes of land cover changes across scales. We attribute land cover changes to ecological, climatic, and human drivers. These reconstructions provide benchmarks for Earth System Models.

In August 2022, 65 scientists from 13 countries gathered in Antigua, Guatemala, for a workshop, co-funded by the US National Science Foundation and the International Continental Scientific Drilling Program. This workshop considered the potential of establishing a continental scientific drilling program in the Lake Izabal Basin, eastern Guatemala, with the goals of establishing a borehole observatory and investigating one of the longest continental records from the northern Neotropics.

Citizen scientists often submit high-quality data, but a robust method for assessing data quality is needed. This study develops a semi-automated program that characterizes the mistakes made by citizen scientists by grouping them into communities of citizen scientists with similar mistake tendencies and flags potentially erroneous data for further review. This work may help citizen science programs assess the quality of their data and can inform training practices.

This study shows that previously reported underestimations of water ages are most likely not due to the use of seasonally variable tracers. Rather, these underestimations can be largely attributed to the choices of model approaches which rely on assumptions not frequently met in catchment hydrology. We therefore strongly advocate avoiding the use of this model type in combination with seasonally variable tracers and instead adopting StorAge Selection (SAS)-based or comparable model formulations.

Disturbance events from historic sediments from a small lake in Oregon were compared to known events to determine if Cascadia earthquakes are uniquely identifiable. Sedimentological methods and geochemical provenance data identify a deposit likely from the most recent Cascadia earthquake (which occurred in 1700), another type of earthquake deposit, and flood deposits, suggesting that small lakes are good recorders of megathrust earthquakes. New methods developed hold promise for other lakes.

We report aspartic and glutamic acid racemization analyses on Neogloboquadrina pachyderma and Cibicidoides wuellerstorfi from the Arctic Ocean (AO). The rates of racemization in the species are compared. Calibrating the rate of racemization in C. wuellerstorfi for the past 400 ka allows the estimation of sample ages from the central AO. Estimated ages are older than existing age assignments (as previously observed for N. pachyderma), confirming that differences are not due to taxonomic effects.

Accurately quantifying how the global hydrological cycle will change in the future remains challenging due to the limited availability of historical climate data from the tropics. Here we present the CoralHydro2k database – a new compilation of peer-reviewed coral-based climate records from the last 2000 years. This paper details the records included in the database and where the database can be accessed and demonstrates how the database can investigate past tropical climate variability.

Our analysis of the Santovka sedimentary record in Slovakia uncovered two major climate shifts at 8.2 and 7.4 ka BP. These shifts likely impacted temperature and humidity, and/or air mass circulation, and were caused by the drying of the lake at 7.4 ka BP. The sedimentary infill provides important information on the region's past climate, and future research must focus on its impact on the last hunter gatherers and first farmers in the context of spreading agriculture in Europe.

Rock glaciers are mixtures of ice and rock debris that are common landforms in high-mountain environments. We evaluated the role of rock glaciers as a component of mountain hydrology by collecting water samples during the summer and fall of 2021. Our results indicate that the water draining from rock glaciers late in the melt season is likely derived from old buried ice; they further demonstrate that this water collectively makes up about a quarter of streamflow during the month of September.

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.

Annually banded lake sediment can track environmental change with high resolution in locations where alternatives are not available. Yet, information about chronology is often affected by poor appearance. Traditional methods struggle with these records. To overcome this obstacle we demonstrate a Bayesian approach that combines information from radiocarbon dating and laminations on cores from Columbine Lake, Colorado, expanding possibilities for producing high-resolution records globally.

We present a method to reconstruct burnt area using a relationship between pollen and charcoal abundances and the calibration of charcoal abundance using modern observations of burnt area. We use this method to reconstruct changes in burnt area over the past 12 000 years from sites in Iberia. We show that regional changes in burnt area reflect known changes in climate, with a high burnt area during warming intervals and low burnt area when the climate was cooler and/or wetter than today.

A large drought potentially occurred roughly 4200 years ago, but its impacts and significance are unclear. We find new evidence in carbonate oxygen isotopes from a mountain lake in southeastern Wyoming, southern Rocky Mountains, of an abrupt reduction in effective moisture (precipitation–evaporation) or snowpack from approximately 4200–4000 years ago. The drought's prominence among a growing number of sites in the North American interior suggests it was a regionally substantial climate event.

Subarctic and Arctic lake sediments provide key data to understand natural climate variability and future climate change. However, they can be difficult to date accurately and of limited use without a robust chronology. We use volcanic ash deposits from the last ~4000 BP to identify anomalously old radiocarbon ages at Cascade Lake, Alaska. A provisional ~15 000-year Bayesian age model is produced for the lake, and a new location for ash from five Late Holocene eruptions is reported.

The density of rain gauge networks plays an important role in radar rainfall bias correction. In this work, we aimed to assess the extent to which daily rainfall observations from a dense network of citizen scientists improve the accuracy of hourly radar rainfall estimates in the Tubma Basin, Thailand. Results show that citizen rain gauges significantly enhance the performance of radar rainfall bias adjustment up to a range of about 40 km from the center of the citizen rain gauge network.

The investigation of groundwater–lake-water interactions in highly permeable boreal terrain using several indicators showed that lowland lakes are embedded into the groundwater system and are thus relatively resilient to short-term hydroclimatic change, while upland lakes rely more on precipitation as their main water input, making them more sensitive to evaporative drawdown. This suggests that landscape position controls the vulnerability of lake-water levels to hydroclimatic change.

We use satellite InSAR to inventory and monitor rock glaciers, frozen bodies of ice and rock debris that are an important water resource in the Uinta Mountains, Utah, USA. Our inventory contains 205 rock glaciers, which occur within a narrow elevation band and deform at 1.94 cm yr-1 on average. Uinta rock glacier movement changes seasonally and appears to be driven by spring snowmelt. The role of rock glaciers as a perennial water resource is threatened by ice loss due to climate change.

This study investigates the effects of climate change on runoff patterns in six Alpine catchments in Austria at the end of the 21st century. Our results indicate a substantial shift to earlier occurrences in annual maximum and minimum flows in high-elevation catchments. Magnitudes of annual extremes are projected to increase under a moderate emission scenario in all catchments. Changes are generally more pronounced for high-elevation catchments.

Paleomagnetic data from Cascade Lake (Brooks Range, Alaska) extend the radiometric-based age model of the sedimentary sequence extending back 21 kyr. Correlated ages based on prominent features in paleomagnetic secular variations (PSV) diverge from the radiometric ages in the upper 1.6 m, by up to about 2000 years at around 4 ka. Four late Holocene cryptotephra in this section support the PSV chronology and suggest the influence of hard water or aged organic material.

The drivers of high accumulation of single-cell siliceous algae (diatoms) in a high-latitude lake have not been fully characterized before. We studied silicon cycling of the lake through water, radon, silicon, and stable silicon isotope balances. Results showed that groundwater brings 3 times more water and dissolved silica than the stream inlet. We demonstrate that groundwater discharge and low sediment deposition have driven the high diatom accumulation in the studied lake in the past century.

This study investigated a cave in Utah (USA) that contains a deposit of perennial ice. Such ice caves are important sources of information about past climate and are currently threatened by rising temperatures. The origin (precipitation), thickness (3 m), and age (several centuries) of the ice were constrained by a variety of methods. Liquid water recently entered the cave for the first time in many years, suggesting a destabilization of the cave environment.

The Last Interglacial (129–116 ka) experienced global temperatures and sea levels higher than today. The direct contribution of warmer conditions to global sea level (thermosteric) are uncertain. We report a global network of sea surface temperatures. We find mean global annual temperature anomalies of 0.2 ± 0.1˚C and an early maximum peak of 0.9 ± 0.1˚C. Our reconstruction suggests warmer waters contributed on average 0.08 ± 0.1 m and a peak contribution of 0.39 ± 0.1 m to global sea level.

Recent technological advances allow researchers to obtain radiocarbon ages from smaller samples than previously possible. We investigate the reliability and precision of radiocarbon ages obtained from miniature (11–150 μg C) samples of terrestrial plant fragments taken from sediment cores from Lake Żabińskie, Poland. We further investigate how sampling density (the number of ages per 1000 years) and sample mass (which is related to age precision) influence the performance of age–depth models.

The Past Global Changes LandCover6k initiative will use archaeological records to refine scenarios of land use and land cover change through the Holocene to reduce the uncertainties about the impacts of human-induced changes before widespread industrialization. We describe how archaeological data are used to map land use change and how the maps can be evaluated using independent palaeoenvironmental data. We propose simulations to test land use and land cover change impacts on past climates.

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.

Rapid climate warming is impacting physical processes in Arctic environments. Glacier–fed lakes are influenced by many of these processes, and they are impacted by the changing behavior of weather, glaciers, and rivers. We present data from weather stations, river gauging stations, lake moorings, and more, following 4 years of environmental monitoring in the watershed of Lake Peters, a glacier–fed lake in Arctic Alaska. These data can help us study the changing dynamics of this remote setting.

We report amino acid racemization analyses of foraminifera from well-dated sediment cores from the Yermak Plateau, Arctic Ocean. Sample ages are compared with model predictions, revealing that the rates of racemization generally conform to a global compilation of racemization rates at deep-sea sites. These results highlight the need for further studies to test and explain the origin of the purportedly high rate of racemization indicated by previous analyses of central Arctic sediments.

The last time atmospheric CO2 was similar to the present was 3–4 million years ago. The Arctic was warmer compared to the global average, and the causes are not fully known. To investigate this, we reconstructed summer temperature, forest fire and vegetation at a 3.9 Ma fen peat in Arctic Canada. The summer temperatures averaged 15.4 °C, and charcoal was abundant. Interactions between vegetation and climate were mediated by fire and may contribute to high Arctic temperatures during the Pliocene.

A new annually resolvable sedimentary record of southern hemisphere climate has been recovered from Lake Ohau, South Island, New Zealand. The Lake Ohau Climate History (LOCH) Project acquired cores from two sites that preserve an 80 m thick sequence of laminated mud that accumulated since the lake formed ~ 17 000 years ago. Cores were recovered using a purpose-built barge and drilling system designed to recover soft sediment from relatively thick sedimentary sequences at water depths up to 100 m.

A synthesis of 93 published records reveals that moisture availability increased over large portions of North America over the past 2000 years, the Common Era (CE). In many records, the second millennium CE tended to be wetter than the first millennium CE. The long-term changes formed the background for annual to multi-decade variations, such as "mega-droughts", and also provide a context for amplified rates of hydrologic change today.

Padul is a classical and very unique site from the Mediterranean area as it contains a very long and continuous Quaternary sedimentary record. However, the uppermost part of the record was never recovered. In this study we focus on the last 4700 cal yr BP of Holocene climate variability and human activity in the Mediterranean area.

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.

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).

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.

We report on a planned Trans-Amazon Drilling Project (TADP) that will continuously sample Late Cretaceous to modern sediment in a transect along the equatorial Amazon of Brazil, from the Andean foreland to the Atlantic Ocean. The TADP will document the evolution of the Neotropical forest and will link biotic diversification to changes in the physical environment, including climate, tectonism, and landscape. We will also sample the ca. 200Ma basaltic sills that underlie much of the Amazon.

We propose an innovative framework to organize paleodust records, formalized in a publicly accessible database, and discuss the emerging properties of the global dust cycle during the Holocene by integrating our analysis with simulations performed with the Community Earth System Model. We show how the size distribution of dust is intrinsically related to the dust mass accumulation rates and that only considering a consistent size range allows for a consistent analysis of the global dust cycle.

Understanding how early farmers adapted to their environments is important regarding how we respond to the changing climate. Here, we present wood charcoal records from northwestern China to explore human–environmental interactions. Our data suggest that people started managing chestnut trees around 4600 BP and cultivating fruit trees and transporting conifers from 3500 BP. From 2500 BP, people established horticultural systems, showing that they actively adapted to the environment.

One of the main uncertainties related to future climate change has to do with how aerosols interact with climate. Dust is the most abundant aerosol in the atmosphere by mass. In order to better understand the links between dust and climate, we can turn to geological archives of ancient dust. Paleo±Dust is a compilation of measured values of the paleo-dust deposition rate. We can use this compilation to guide climate models so that they better represent dust–climate interactions.

We estimate an average (stack) of Western Pacific Warm Pool (WPWP) sea surface climate records over the last 800 kyr from 10 ocean sediment cores. To better understand glacial–interglacial differences between the tropical WPWP and high-latitude climate change, we compare our WPWP stack to global and North Atlantic deep-ocean stacks. Although we see similar timing in glacial–interglacial change between the stacks, the WPWP exhibits less amplitude of change.

This paper focuses on volcanic ash (tephra) in European annually laminated (varve) lake records from the period 25 to 8 ka. Tephra enables the synchronisation of these lake records and their proxy reconstructions to absolute timescales. The data incorporate geochemical data from tephra layers across 19 varve lake records. We highlight the potential for synchronising multiple records using tephra layers across continental scales whilst supporting reproducibility through accessible data.

During the last glacial period, cold conditions associated with changes in atmospheric circulation resulted in the deposition of widespread loess. It seems that the phases of loess accumulation were not strictly synchronous. To test this hypothesis, the chronology of loess deposition in different regions of Europe was studied by recalculating 1423 luminescence ages in a database. Our study discusses the link between the main loess sedimentation phases and the maximal advance of glaciers.

Volcanism is a key driver of climate. Based on ice cores from Greenland and Antarctica, we reconstruct its climate impact potential over the Holocene. By aligning records on a well-dated chronology from Antarctica, we resolve long-standing inconsistencies in the dating of past volcanic eruptions. We reconstruct 850 eruptions (which, in total, injected 7410 Tg of sulfur in the stratosphere) and estimate how they changed the opacity of the atmosphere, a prerequisite for climate model simulations.

The last interglacial (LIG; 130 to 115 ka) is a useful analogue for improving predictions of future changes to sea level. Here, we describe the location and characteristics of 82 LIG marine sites from the glaciated Northern Hemisphere (Russia, northern Europe, Greenland and North America). Sites are located in a variety of settings, including boreholes, riverbank exposures and along coastal cliffs.

Here we present a global chronology framework of 2831 palynological records, including globally harmonized chronologies covering up to 273 000 years. A comparison with the original chronologies reveals a major improvement according to our assessment. Our chronology framework and revised chronologies will interest a broad geoscientific community, as it provides the opportunity to make use in synthesis studies of, for example, pollen-based vegetation and climate change.

The datasets presented alongside this manuscript contain high-resolution concentration measurements of chemical impurities in deep ice cores, NGRIP and NEEM, from the Greenland ice sheet. The impurities originate from the deposition of aerosols to the surface of the ice sheet and are influenced by source, transport and deposition processes. Together, these records contain detailed, multi-parameter records of past climate variability over the last glacial period.

Using microfossils to gauge the age of rocks and sediments requires an accurate age of their first (origination) and last (extinction) appearances. But how do you know such ages can then be applied worldwide? And what causes regional differences? This paper investigates the regional consistency of ranges of species of a specific microfossil group, organic-walled dinoflagellate cysts. This overview helps in identifying regional differences in the stratigraphic ranges of species and their causes.

Radiolarians found in marine sediments are used to reconstruct past Southern Ocean environments. This requires a comprehensive modern dataset. The Southern Ocean Radiolarian (SO-RAD) dataset includes radiolarian counts from sites in the Southern Ocean. It can be used for palaeoceanographic reconstructions or to study modern species diversity and abundance. We describe the data collection and include recommendations for users unfamiliar with procedures typically used by the radiolarian community.

The Tibetan Plateau is quite remote, and it is difficult to collect samples on it; the previous modern pollen data are located on a nearby road, and there is a large geographic gap in the eastern and central Tibetan Plateau. Our novel pollen data can fill the gap and will be valuable in establishing a complete dataset covering the entire Tibetan Plateau, thus helping us to get a comprehensive understanding. In addition, the dataset can also be used to investigate plant species distribution.

The last interglacial (Marine Isotope Stage 5e – MIS 5e) occurred between 128 and 116 ka when sea level was about 6–8 m above its present level; sea-level changes during this period are still debated. MIS 5e represents a potential future warm-climate analogue. This paper presents an open-access database based on the review of MIS 5e coral reef records from many tropical Pacific islands. Overall, the database contains 318 age data points and 94 relative sea-level data points from 38 studies.

Sea levels during the last interglacial (130 to 73 ka) are seen as possible process analogs for future sea-level-rise scenarios as our world warms. To this end we catalog previously published ancient shoreline elevations and chronologies in a standardized data format for East Africa and the Western Indian Ocean region. These entries were then contributed to the greater World Atlas of Last Interglacial Shorelines database.

Changes in sea level during Marine Isotope Stage (MIS) 5e are comparable to modern sea levels in our global climate. Contributing to the World Atlas of Last Interglacial Shorelines (WALIS), this paper reviewed data from over 70 studies detailing sea-level markers for MIS 5e around Japan. Most sea-level markers were found as marine terraces and are often dated by comparison to dated volcanic ash or sediment layers, which has connected Japan’s landforms to global patterns of sea-level change.

During the last interglacial (130 to 115 ka), global sea level was higher than present. The World Atlas of Last Interglacial Shorelines (WALIS) has been created to document this. In this paper, we have compiled data for southeastern South America. There are landforms that indicate that sea level was 5 to 25 m higher than present during this time period. However, the quality of these data is hampered by limitations on elevation measurements, chronology, and geological descriptions.

The Last Interglacial (129–116 ka) experienced global temperatures and sea levels higher than today. The direct contribution of warmer conditions to global sea level (thermosteric) are uncertain. We report a global network of sea surface temperatures. We find mean global annual temperature anomalies of 0.2 ± 0.1˚C and an early maximum peak of 0.9 ± 0.1˚C. Our reconstruction suggests warmer waters contributed on average 0.08 ± 0.1 m and a peak contribution of 0.39 ± 0.1 m to global sea level.

Reconstructions try to extract a climate signal from paleo-observations. It is essential to understand their uncertainties. Similarly, comparing climate simulations and paleo-observations requires approaches to address their uncertainties. We describe a simple but flexible noise model for climate proxies for temperature on millennial timescales, which can assist these goals.

Evenly spaced carbon and oxygen stable isotope records were produced from central European stalagmites. To mitigate the potential bias of interpolation, the variance spectra were carefully evaluated. The derived data are ready to use with conventional uni- and multivariate statistics, which are usually not prepared to handle the general characteristic of sedimentary paleoclimate records derived from geological sequences unevenly sampled in time.

We created a database of 2134 marine sediment cores above 30° N in the North Pacific from 1951 to 2016 to facilitate paleoceanographic and paleoclimate research. This database allows for accessibility to sedimentary sequences, age models, and proxies produced in the North Pacific. We found community-wide shifts towards multiproxy investigation and increased age model generation. The database consolidates the research efforts of an entire community into an efficient tool for future investigations.

We document our best available data compilation of published ice core records of the greenhouse gases CO2, CH4, and N2O and recent measurements on firn air and atmospheric samples covering the time window from 156 000 years BP to the beginning of the year 2016 CE. A smoothing spline method is applied to translate the discrete and irregularly spaced data points into continuous time series. The radiative forcing for each greenhouse gas is computed using well-established, simple formulations.

Short summary
We present a curated database of western North American Holocene paleoclimate records, which have been screened on length, resolution, and geochronology. The database gathers paleoclimate time series that reflect temperature, hydroclimate, or circulation features from terrestrial and marine sites, spanning a region from Mexico to Alaska. This publicly accessible collection will facilitate a broad range of paleoclimate inquiry.
