i. C-PEAT - Carbon in Peat on Earth through Time
Session B018: Carbon Cycling in Global Peatlands (Biogeosciences)
Convenors: Torben R Christensen, Oliver Sonnentag, Nicole K Sanderson (ECC), Julie Loisel
In this session, we invite the global peatland community to present their research on the carbon cycle in intact and degraded peatlands across latitudes. Studies from a wide range of global peatlands, including arctic, boreal, temperate and tropical peatlands are welcome. We encourage studies including but not limited to laboratory and field experiments, flux measurements, remote sensing, microbial ecology, paleoecological studies and process-based or large-scale modeling. Efforts to understand current dynamics as well as studies exploring the past, present and future natural peatland responses to climate as well as to land use change are welcome.
ii. CVAS - Climate Variability Across Scales
Session NG004 - Climate Variability Across Scales and Climate States
Convenors: Raphaël Hébert, Shaun Lovejoy, Mara Young McPartland (ECC)
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.
This session aims to provide a forum to present work on:
Characterization of climate dynamics using a variety of techniques (e.g. scaling and multifractal techniques and models, recurrence plots, variance analyses). Relationship between mean state changes (e.g. glacial to interglacial or pre-industrial to present to future), and higher-order moments of relevant climate variables, including extreme-event occurrence and predictability.
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. Synchronization and pacing of glacial cycles through dynamical interaction of external forcing (e.g. orbital forcing) and internal variability.Characterization of the probabilities of extremes, including linkage between slow climate variability and extreme event recurrence.
Members of the PAGES working group on Climate Variability Across Scales (CVAS) and others are welcome.
iii. VICS - Volcanic Impacts on Climate and Society
Session: A039 - Climatic, environmental and societal impacts of volcanic eruptions
Convenors: Davide Zanchettin, Francesco S.R. Pausat, Matthew Toohey, Lauren Marshall (ECC)
Volcanic eruptions can significantly alter the Earth's radiation budget and cause climate perturbations on interannual to multidecadal time scales. Ultimately, they may influence the biosphere and local and regional environments as well as societies. Our understanding of volcanic impacts on climate remains hampered by the paucity of observed eruptions, uncertainties in volcanic forcing datasets, limitations of proxy-based climate evidence, uncertainties of global aerosol model simulations and inconsistencies of responses across climate models. Also, how volcanic forcing will affect future climates remains uncertain. This session aims at bringing together researchers studying the impact of volcanic eruptions on climate variability and predictability by means of observations, climate reconstruction studies, and modeling. We aim to highlight contributions conducted under the umbrella of CMIP6, especially the VolMIP and PMIP4 activities, contributions aligned with the PAGES-VICS working group and with the SPARC SSiRC activity.
Session GC038 - Explaining and Predicting Earth System Change: A World Climate Research Programme Call to Action. Coupling of Observations and Models; Integrated Attribution, Prediction and Projection; Assessment of Current and Future Hazards
Convenors: Kirsten Lynn Findell, Zhuo Wang, Isla Simpson,Haiyan Teng
The World Climate Research Programme (WCRP) envisions a world “that uses sound, relevant, and timely climate science to ensure a more resilient present and sustainable future for humankind.” The goal of the WCRP Lighthouse Activity on Explaining and Predicting Earth System Change is to develop an integrated capability to understand, attribute, and predict changes in the Earth system on multi-annual to decadal timescales and global to regional space scales, including capabilities for early warning of potential high impact changes and events. With this session we aim to document current research, identify challenges, and explore potential pathways towards achieving this goal. We invite contributions in three thematic areas: (i) monitoring and modelling Earth system change, particularly approaches demonstrating tight coupling between observational and modeling efforts; (ii) integrated attribution, prediction and projection of Earth system change, and (iii) assessment of current and future hazards, such as tropical cyclones, heatwaves and droughts.
PAGES SSC Member sessions
Session A077 - Observed and simulated mid-latitude air-sea interaction and inter-basin teleconnections
Convenors: Aixue Hu, Yoshi N Sasaki, Noel Keenlyside, Rhys Parfitt
Air-sea interaction is an important driving mechanism for numerous weather and climate phenomena, such as extratropical and tropical cyclones, storm tracks, blockings, atmospheric circulation changes, IPV and AMV, etc. Teleconnections between different ocean basins through atmospheric and oceanic bridges on various timescales can magnify certain weather and climate events downstream. To serve the broader community better, a predictive understanding of these interactions and teleconnections ranging from seasonal to decadal timescales would greatly advance our capability of simulating and predicting these processes. It is also essential to find out whether these interactions and teleconnections in mid-latitudes would change under changing climate and how the internal climate mode variability would affect them. In this session, we welcome abstracts studying the observed and model simulated mid-latitude air-sea interactions and the inter-basin teleconnections on multiple timescales and how the various external forcings, e.g., solar, volcano, anthropogenic forcing, would modulate these processes.
Selected relevant sessions
Session PP006 - Climate of the Common Era
Convenors: Sloan Coats, Elizabeth Jane Wallace, Mukund Palat Rao
This session highlights recent work on all aspects of the climate of the last 2000 years (the Common Era), using new proxy records, data syntheses, reconstruction methodologies, proxy system modeling, and paleoclimate model simulations. Contributions that combine several of the above areas or that utilize the latest generation of paleoclimate model simulations and data assimilation techniques are particularly welcome. A focus of this year's session will be characterizations of internal and externally forced climate variability using paleoclimate evidence. New means of reconstructing modes of internal climate variability and associated teleconnections, as well as attempts to characterize the impacts of external forcing on these modes, are particularly encouraged.
