Over the past 800 thousand years, variations in the Earth’s orbit and tilt have caused antiphased solar insolation intensity in the Northern and Southern Hemispheres. Paradoxically, glacial records suggest that global ice sheets have responded synchronously to major cold glacial and warm interglacial episodes. To address this puzzle, we present a new detailed glacier chronology that estimates the timing of multiple Patagonian ice-sheet waxing and waning cycles over the past 300 thousand years.

Understanding the history and drivers of Greenland Ice Sheet change is important to forecast future ice sheet retreat. We combined geologic mapping and cosmogenic nuclide measurements to investigate how the Greenland Ice Sheet formed the landscape of Inglefield Land, northwest Greenland. We found that Inglefield Land was covered by warm- and cold-based ice during multiple glacial cycles and that much of Inglefield Land is an ancient landscape.

We date sedimentary deposits showing that the southeastern Laurentide Ice Sheet was at or near its southernmost extent from ~ 26 000 to 21 000 years ago, when sea levels were at their lowest, with climate records indicating glacial conditions. Slow deglaciation began ~ 22 000 years ago, shown by a rise in modeled local summer temperatures, but significant deglaciation in the region did not begin until ~ 18 000 years ago, when atmospheric CO2 began to rise, marking the end of the last ice age.

Understanding how much the Greenland ice sheet melted in response to past warmth helps better predicting future sea-level change. Here we present a framework for using numerical ice-sheet model simulations to provide constraints on how much mass the ice sheet loses before different areas become ice-free. As observations from subglacial archives become more abundant, this framework can guide subglacial sampling efforts to gain the most robust information about past ice-sheet geometries.

We take advantage of a site in Alaska – where climate records are limited and a former alpine glacier deposited a dense sequence of moraines spanning the full deglaciation – to construct a proxy summer temperature record. Building on age constraints for moraines in the valley, we reconstruct paleo-glacier surfaces and estimate the summer temperatures (relative to the Little Ice Age) for each moraine. The record suggests that the influence of North Atlantic climate forcing extended to Alaska.

The Armorican region (NW France), is marked by several old coastal and marine markers that are today located several tens of meters above the sea level. This fact is commonly explained by sea-level variations and complex tectonic processes (e.g. mantle dynamic). In this study we test the role of the erosion and the associated flexural (lithospheric bending) response. We show that this simple model of flexural adjustment is to be taken into account to explain the regional evolution.

Radiocarbon is best known as a dating tool, but it also allows us to track CO2 exchange between the ocean and atmosphere. Using decades of data and novel mapping methods, we have charted the ocean’s average radiocarbon ″age” since the last Ice Age. Combined with climate model simulations, these data quantify the ocean’s role in atmospheric CO2 rise since the last Ice Age while also revealing that Earth likely received far more cosmic radiation during the last Ice Age than hitherto believed.

Glacial erosion is a fundamental process operating on Earth's surface. Two processes of glacial erosion, abrasion and plucking, are poorly understood. We reconstructed rates of abrasion and quarrying in Greenland. We derive a total glacial erosion rate of 0.26 ± 0.16 mm per year. We also learned that erosion via these two processes is about equal. Because the site is similar to many other areas covered by continental ice sheets, these results may be applied to many places on Earth.

Our study developed a record of glacier and climate change in the Mackenzie and Selwyn mountains of northwestern Canada over the past several hundred years. We estimate temperature change in this region using several methods and incorporate our glacier record with models of climate change to estimate how glacier volume in our study area has changed over time. Models of future glacier change show that our study area will become largely ice-free by the end of the 21st century.

Cosmogenic nuclides like 10Be are rare isotopes created in rocks exposed at the Earth’s surface and can be used to understand glacier histories and landscape evolution. 10Be is usually measured in the mineral quartz. Here, we show that 10Be can be reliably measured in the mineral pyroxene. We use the measurements to determine exposure ages and understand landscape processes in rocks from Antarctica that do not have quartz, expanding the use of this method to new rock types.

We present new tools in the landscape evolution model Badlands to simulate 10Be production, erosion and transport. These tools are applied to a source-to-sink system in the SW French Alps, where the model is calibrated. We propose a model that fits river incision rates and 10Be concentrations in sediments, and we show that 10Be in deep marine sediments is a signal with multiple contributions that cannot be easily interpreted in terms of climate forcing.

The 7.4 m of sea level equivalent stored as Greenland ice is getting smaller every year. The uncertain trajectory of ice loss could be better understood with knowledge of the ice sheet's response to past climate change. Within the bedrock below the present-day ice sheet is an archive of past ice-sheet history. We analyze all available data from Greenland to create maps showing where on the ice sheet scientists can drill, using currently available drills, to obtain sub-ice materials.

Alpine landscapes are transformed by several erosion processes. 10Be concentrations measured in river sediments at the outlet of a basin represent a powerful tool to quantify how fast the catchment erodes. We measured erosion rates within the Dora Baltea catchments (western Italian Alps). Our results show that erosion is governed by topography, bedrock resistance and glacial imprint. The Mont Blanc massif has the highest erosion and therefore dominates the sediment flux of the Dora Baltea river.

Landscape evolution is highly dependent on climatic parameters, and the occurrence of intense precipitation events is considered to be an important driver of river incision. We compare the rate of erosion with the variability of river discharge in a mountainous landscape of SE France where high-magnitude floods regularly occur. Our study highlights the importance of the hypotheses made regarding the threshold that river discharge needs to exceed in order to effectively cut down into the bedrock.

Glacier reconstructions provide insights into past climatic conditions and elucidate processes and feedbacks that modulate the climate system both in the past and present. We investigate the transition from the last glacial to the current interglacial and generate beryllium-10 moraine chronologies in glaciated catchments of the eastern European Alps. We find that rapid warming was superimposed by centennial-scale cold phases that appear to have influenced large parts of the Northern Hemisphere.

Cosmogenic nuclide surface exposure dating is commonly used to constrain the timing of past glacier extents. However, Antarctic exposure age datasets are often scattered and difficult to interpret. We compile new and existing exposure ages of a glacial deposit with independently known age constraints and identify surface processes that increase or reduce the likelihood of exposure age scatter. Then we present new data for a previously unmapped and undated older deposit from the same region.

We assess the 14C plateau tuning technique used to date marine sediments and determine 14C marine reservoir ages. We identify problems linked to assumptions of the technique, the assumed shapes of the 14C / 12C records, and the sparsity and uncertainties in both atmospheric and marine data. Our concerns are supported with carbon cycle box model experiments and statistical simulations, allowing us to question the ability to tune 14C age plateaus in the context of noisy and sparse data.

Large sorted stone stripes have been discovered on the 4000 m high central Sanetti Plateau of the tropical Bale Mountains in Ethiopia. The stripes are a mystery as similar landforms have so far only been reported in the temperate zone and polar regions. Our investigations suggest that the stripes formed in the vicinity of a former ice cap on the plateau during a much colder climatic period. The distinct pattern is the result of a process related to cyclic freezing and thawing of the ground.

Retreat of the Greenland Ice Sheet (GrIS) margin is exposing a bedrock landscape that holds clues regarding the timing and extent of past ice-sheet minima. We present cosmogenic nuclide measurements from recently deglaciated bedrock surfaces (the last few decades), combined with a refined chronology of southwestern Greenland deglaciation and model simulations of GrIS change. Results suggest that inland retreat of the southwestern GrIS margin was likely minimal in the middle to late Holocene.

A recent analysis of stable isotopes of samples from larch and cembran trees, revealed that δD and δ18O exhibit no trends in adult trees, but trends in the juvenile period. In this work we applied a correlation analysis on different cambial age to verify if these changes were correlated with tree-ring width values. The results prove a significant correlation between tree-ring-width and both hydrogen and oxygen stable isotopes before 100 year of cambial age, but not afterwards, in both species.

Stable isotopes in tree-ring cellulose are tools for climatic reconstructions, but interpretation is challenging due to nonclimate trends. We analyzed the tree-age trends in tree-ring isotopes of deciduous larch and evergreen cembran pine. Samples covering the whole Holocene were collected at the tree line in the Alps. For cambial ages over 100 years, we prove the absence of age trends in δD, δ18O, and δ13C for both species. For lower cambial ages, trends differ for each isotope and species.

Slow-slipping faults are often difficult to identify in landscapes. Here we analyzed high-resolution topographic data from the Valensole area at the front of the southwestern French Alps. We measured various properties of hillslopes such as their relief and the shape of hilltops. We observed systematic spatial variations of hillslope morphology indicative of relative changes in erosion rates. These variations are potentially related to slow tectonic deformation across the studied area.

The topographic steady-state assumption is often used in geomorphology. However, recent studies suggest that a drainage network is more mobile than previously thought. Using landscape evolution models, we show that those migrations have a significant impact on basin-wide denudation rates even if an overall topographic steady state is achieved at large scale. Our approach provides new tools to derive minimal uncertainties in basin-scale denudation rates due to this topographic disequilibrium.

Glacial erosion is known to limit the height of midlatitude mountain ranges affected by substantial glaciation during cold periods. Our study examines this phenomenon in the tropics. A new form of hypsometric analysis, along with other evidence, of 10 tropical ranges reveals widespread signs of a perched glacial base level at the ELA. Although glacial influence is moderate to weak in these environments, the evidence suggests that glacial erosion acts to limit the height of tropical ranges.

Cellulose content (CC (%)) series from two high-Alpine species, Larix decidua Mill. (European larch, LADE) and Pinus cembra L. (Swiss stone pine, PICE) are investigated in modern wood samples and Holocene wood remains from the Early and mid-Holocene. Trends in modern and Holocene time series as well as climate–cellulose relationships for modern trees in the Alps show high potential for CC (%) to be established as novel supplementary proxy in dendroclimatology.

Climate model simulations covering the last millennium provide context for the evolution of the modern climate and for the expected changes during the coming centuries. They can help identify plausible mechanisms underlying palaeoclimatic reconstructions. Here, we describe the forcing boundary conditions and the experimental protocol for simulations covering the pre-industrial millennium. We describe the PMIP4 past1000 simulations as contributions to CMIP6 and additional sensitivity experiments.

The contribution of fossil and non-fossil carbon sources to aerosols sampled in the Arve River valley is quantified with 14C measured by AMS with a CO2 gas source. Results show a high contribution of non-fossil carbon sources during winter, which is highly correlated to levoglucosan concentration, showing that almost all of the non-fossil carbon originates from wood combustion. This correlation is also used to separate the contributions of wood burning and biogenic emissions for summer samples.

Here we utilize declassified spy satellite imagery to quantify ice volume loss of glaciers in the eastern Himalayas over approximately the last three decades. Clean-ice and debris-covered glaciers show similar magnitudes of ice loss, while calving glaciers are contributing a disproportionately large amount to total ice loss. Results highlight important physical processes affecting the ice mass budget and associated water resources in the Himalayas.

Geological evidence for past changes in glacier length provides a useful source of information about pre-historic climate change. We have used glacier modelling to show that air temperature reductions of −5 to −7 °C, relative to present, are required to simulate the glacial extent in the North Island, New Zealand, during the last ice age (approx. 20000 years ago). Our results provide data to assess climate model simulations, with the aim of determining the drivers of past natural climate change.

We present a new 10Be record at EDC between 269 and 355ka. Our 10Be-based accumulation rate is in good agreement with the one associated with the EDC3 timescale except for the warm MIS 9.3 optimum. This suggests that temperature reconstruction from water isotopes may be underestimated by 2.4K for the difference between the MIS 9.3 and present day. The CMIP5-PMIP3 models do not quantitatively reproduce changes in precipitation vs. temperature increase during glacial–interglacial transitions.

Records of the interaction between land and glacial ice movement in the Puget Lowland of Washington State are used to interpret that solid Earth movement provided stability to this marine-terminating glacial ice for at least 500 years. These results are significant because this landscape is similar to parts of the Greenland Ice Sheet and the Antarctic Peninsula, indicating that the interactions seen in this area are applicable to modern glaciated regions.

We used two lake sediment records at different elevations and landscape evidence to find that a southern Greenland outlet glacier advanced ~ 3700 years ago and then retreated ~ 1600 years ago. This retreat is unlike other nearby outlet glaciers, possibly because of the complex local ice structure or greater sensitivity to snowfall. We also find that the advanced ice surface had an elevation of ~ 670 m a.s.l. (~ 250 m higher than today) from ~ 3700 to 1600 years ago.

Retreat of the Greenland Ice Sheet (GrIS) margin is exposing a bedrock landscape that holds clues regarding the timing and extent of past ice-sheet minima. We present cosmogenic nuclide measurements from recently deglaciated bedrock surfaces (the last few decades), combined with a refined chronology of southwestern Greenland deglaciation and model simulations of GrIS change. Results suggest that inland retreat of the southwestern GrIS margin was likely minimal in the middle to late Holocene.

We present new results that show how the north Greenland Ice Sheet responded to climate changes over the last 11 700 years. We find that the ice sheet was very sensitive to past climate changes. Combining our findings with recently published studies reveals distinct differences in sensitivity to past climate changes between northwest and north Greenland. This highlights the sensitivity to past and possible future climate changes of two of the most vulnerable areas of the Greenland Ice Sheet.

In the context of a warming climate, mountain environments are especially vulnerable to a change in the risk pattern. Our study focuses on the past evolution of wet avalanches, likely triggered by warmer temperatures destabilizing the snow cover. In the last 3300 years we observed an increase of wet avalanche occurrence related to human activities, intensifying pressure on forest cover, as well as favorable climate conditions such as warmer temperatures coinciding with retreating glacier phases.

Short summary
Small mountain glaciers advance and recede as a response to summer temperature changes. Dating of glacial landforms with cosmogenic nuclides allowed us to reconstruct the advance and retreat history of an Alpine glacier throughout the past ~ 11 000 years, the Holocene. The results contribute knowledge to the debate of Holocene climate evolution, indicating that during most of this warm period, summer temperatures were similar to or warmer than in modern times.
