PAGES working group sessions
"Climate Variability Across Scales"
Climate Variability Across Scales working group (CVAS)
Conveners: Raphael Hébert, Vanessa Skiba, Shaun Lovejoy
We welcome contributions that improve quantification, understanding, and prediction of climate variability in the Earth system across space and timescales through case studies, idealized or realistic modeling, synthesis, and model-data comparison studies that provide insights into past, present and future climate variability on local to global, and synoptic to orbital timescales. In particular, we welcome contributions making use of paleoclimate data and modeling to understand changes in the climate system dynamics and variability during the last glacial cycle, and the related implications for the future.
This session aims to provide a forum to present work on:
- Characterization of longer than multi-decadal climate dynamics and variability in proxy-data and model simulations
- Proxy-system modeling to improve paleoclimate reconstructions and model-data comparisons
- Results from theoretical and conceptual climate models
- Role of the ocean, atmosphere, cryosphere and land-surface processes in fostering long-term climate variability through linear – or nonlinear – feedbacks and mechanisms.
- Attribution of climate variability to internal and/or forced dynamics, including natural (e.g. volcanic and solar) and anthropogenic forcing changes.
We encourage contributions from the PAGES working group on Climate Variability Across Scales (CVAS), but any contributions that improve our understanding of climate variability and its role in the Earth System across scales are most welcome.
Floods working group
"Flood trends in cultural riverine landscapes. Reconstruction and simulation of temporal and spatial patterns of past floods, atmospheric variability and human action"
Conveners: Lothar Schulte, Thomas Roggenkamp, Daniela Kroehling, Juan Antonio Ballesteros-Canovas, Rachel Lombardi
Climate change may regionally intensify the threat posed by future floods to societies. From a global change perspective, Holocene and historical floods and their spatial and temporal patterns are of particular interest because they can be linked to former climate patterns, a proxy for future climate predictions. Millennial and centennial time series include the very rare extreme events, which are often considered by society as 'unprecedented'. By understanding their timing, magnitude and frequency in conjunction with prevailing climate regime and human activities, we can overcome our lack of information and disentangle the so-called “unknown unknowns”.
The reconstruction and modeling of temporal and spatial flood patterns, related atmospheric variability and flood propagation in river basins under different environmental settings are the foci of this session supported by the PAGES Floods Working Group.
Because flood prone areas, particularly floodplains and wetlands, are in many regions hotspots of economic, social and cultural development (as evidenced, for example, by the location of cultural heritage sites), the historical role of human action in altering flood frequencies, hydro-sedimentary and environmental processes (e.g. contamination) is a priority topic. The key questions are where, when, and how floodplains have been heavily modified by land use, land reclamation, water management, industrialization, mining, etc., suggesting the onset of the Anthropocene?
We welcome interdisciplinary contributions using natural and documentary archives and instrumental data, which provide
i) knowledge from short-term to long-term development of cultural river-landscapes and human-environmental interaction,
ii) reconstruct and model temporal and spatial flood patterns related to atmospheric variability,
iii) develop (supra-) regional historical maps of extreme floods (MEF),
iv) highlight historical risk mitigation strategies of local (e.g. traditional) communities and assess the flood risk of cultural heritage sites, and
vi) collect evidences of the Anthropocene in floodplains.
These different foci and the interdisciplinary integration of information are critical for the provision of robust data sets and baseline information for future flood scenarios, impacts, disaster risk reduction and integrated river management.

Speleothem Isotopes Synthesis and AnaLysis (SISAL)
"Speleothem and karst records - Reconstructing terrestrial climatic and environmental change"
Conveners: Sophie Warken, Laura Endres, Rieneke Weij, Ezgi Unal-Imer, Monika Markowska
Speleothems are key terrestrial archives of regional to global paleoclimatic and paleoenvironmental changes on sub-seasonal to orbital scales. They provide high temporally resolved records which can be accurately and precisely dated using a variety of proxies such as stable O and C isotopes and trace elements. Recent efforts have seen the rise in more non-traditional proxies such as fluid inclusion water isotopes, organic biomarkers, pollen, dead carbon fraction etc.. This advancement towards quantitative reconstructions of past precipitation, temperature, or other environmental variables and climate patterns, are key variables for data-model comparisons and evaluation. Beyond this, caves and karst areas additionally host an enormous suite of other valuable archives such as cave ice, cryogenic carbonates, clastic sediments, tufa, or travertine sequences which complement the terrestrial palaeorecord, and are often associated with important fossils or archaeological findings.
This session aims to integrate recent developments in the field, and invites submissions from a broad range of cave- and karst-related studies from orbital to sub-seasonal timescales.
In particular we welcome contributions from:
(1) (quantitative) reconstructions of past climatic and environmental variables to reconstruct precipitation, vegetation, fire frequency, temperature etc. across different climate zones,
(2) field- and lab-based developments of process-based methods to improve our application of proxy variables,
(3) process and proxy-system model studies as well as integrated research developing and using databases such as SISAL (Speleothem Isotope Synthesis and AnaLysis).
We further welcome advancements in related and/or interdisciplinary areas, which pave the way towards robust (quantitative) interpretations of proxy time series, improve the understanding of proxy-relevant processes, or enable regional-to-global and seasonal-to-orbital scale analyses of the relationships between proxies and environmental parameters.
In addition, research contributing to current international co-ordinated activities, such as the PAGES working group on Speleothem Isotopes Synthesis and AnaLysis (SISAL) and others are welcome.
PAGES-PMIP Working Group on Quaternary Interglacials (QUIGS)
Glacial/Interglacial variability over the last 1.5 Myr
Convener: Eric Wolff | Co-conveners: Christo Buizert, Jenn Campos-AyalaECS, Margareta Hansson, Inès Ollivier
Over the last 1.5 Myr, the rhythm of Earth’s glaciations changed from a 40 kyr to a 100 kyr periodicity, crossing the Mid-Pleistocene Transition (MPT).
This transition does not follow directly from Milankovitch theory. Against the background of ongoing deep ice drilling projects and blue ice studies
in Antarctica, we encourage the broader paleo community to show their latest results on the glacial dynamics of the 40 kyr and 100 kyr worlds, and the MPT.
We invite presentations on proxy studies of paleo-environmental conditions and processes, as well as model studies providing insight into the dynamics and
drivers of the Earth climate system.
Volcanic Impacts on Climate and Society (VICS)
"Volcano-climate impacts and the stratospheric aerosol layer"
Conveners: Graham Mann, Myriam Khodri, Shih-Wei Fang, Matthew Toohey, Claudia Timmreck
Volcanic aerosol clouds from major tropical eruptions cause periods of strong surface cooling in the historical climate record and are dominant influences within decadal surface temperature trends. Advancing our understanding of the influence of volcanoes on climate relies upon better knowledge of:
(i) the radiative forcings of past eruptions and the microphysical, chemical and dynamical processes which affect the evolution of stratospheric aerosol properties and
(ii) the response mechanisms governing post-eruption climate variability and their dependency on the climate state at the time of the eruption.
This can only be achieved by combining information from satellite and in-situ observations of recent eruptions, stratospheric aerosol and climate modelling activities, and reconstructions of past volcanic histories and post-eruption climate state from proxies.
In recent years the smoke from intense wildfires in North America and Australia has also been an important component of the stratospheric aerosol layer, the presence of organic aerosol and meteoric particles in background conditions now also firmly established.
This session seeks presentations from research aimed at better understanding the stratospheric aerosol layer, its volcanic perturbations and the associated impacts on climate through the post-industrial period (1750-present) and also those further back in the historical record.
Observational and model studies on the stratosphere and climate impacts from the 2022 eruption of Hunga Tonga are also especially welcomed.
We also welcome contributions to understand the societal impacts of volcanic eruptions and the human responses to them. Contributions addressing volcanic influences on atmospheric composition, such as changes in stratospheric water vapour, ozone and other trace gases are also encouraged.
The session aims to bring together research contributing to several current international co-ordinated activities: SPARC-SSiRC, CMIP7-VolMIP, CMIP7-PMIP, and PAGES-VICS.

Research and training network on understanding Deep icE corE Proxies to Infer past antarctiC climatE dynamics (DEEPICE)
"State-of-the-art in ice core sciences"
Conveners: Rachael Rhodes, Hans Christian Steen-Larsen, Lison Soussaintjean, Piers Larkman, Thomas Blunier
The half-century since the first deep ice core drilling at Camp Century, Greenland, has seen increased spatial coverage of polar ice cores, as well as extensive development in methods of ice sample extraction, analysis and interpretation. This growth and innovation continues as we address pressing scientific questions surrounding past climate dynamics, environmental variability and glaciological phenomena. New challenges include the retrieval of old, highly thinned ice, interpretation of altered chemical signals, and the integration of chemical proxies into earth system models. We invite contributions reporting the state-of-the-art in ice coring sciences, including drilling and processing, dating, analytical techniques, results and interpretations of ice core records from polar ice sheets and mid- and low-latitude glaciers, remote and autonomous methods of surveying ice stratigraphy, proxy system modelling and related earth system modelling. We particularly encourage submissions from early career researchers from across the broad international ice core science community. This session is supported by the European DEEPICE training network for early career scientists.

"High impact climate events and storylines: from physical understanding to impacts and solutions"
Convener: Timo Kelder| Co-conveners: Erich Fischer, Henrique Moreno Dumont Goulart, Laura Suarez-Gutierrez, Karin van der Wiel
Recent extreme events with intensities unprecedented in the observational record are causing high impacts globally. The northern hemisphere summer of 2023 saw exceptional heat in North America, Europe and China. Sea surface temperatures across the North Atlantic and the Mediterranean reached record levels while the Antarctic sea ice was record low. Marine heatwaves affected almost the entire tropical north Atlantic.
Some of these events would have been nearly impossible without human-made climate change and broke records by large margins. Further, compound behaviour and cascading effects and risks are becoming evident, such as the spike in food prices induced by the effects of the war in Ukraine on top of concurrent drought across regions with subsequent crop failure. Finally, continuing warming does not only increase the frequency and intensity of events like these, or other until yet unprecedented extremes, it also potentially increases the risk of crossing tipping points and triggering abrupt changes. In order to increase preparedness for high impact climate events, it is important to develop methods and models that are able to represent these events and their impacts, and to better understand how to reduce the risks.
This session aims to bring together the latest research on modelling, understanding, development of storylines and managing plausible past and future high impact climate events and their impacts. We are interested in rare and low-probability heavy precipitation events, droughts, floods, storms and temperature extremes from time scales of hours to decades, including compound, cascading, and connected extremes, high-impact event storylines, as well as the effect of tipping points and abrupt changes driven by climate change, societal response, or other mechanisms (e.g., volcanic eruption).
We welcome a variety of methods to quantify and understand high-impact climate events in present and future climates, such model experiments and intercomparisons; insights from paleo archives; climate projections (including large ensembles, and unseen events); attribution studies; and the development of storylines. We invite work on tipping elements/tipping points; abrupt changes; worst case scenarios; identification of adaptation limits; and the opportunities and solutions to manage the greatest risks.
The session is further informed by the World Climate Research Programme lighthouse activities on Safe Landing Pathways and Understanding High-Risk Events.
