PAGES-supported sessions

Forest Dynamics - B51J: Alteration of disturbance-driven forest dynamics under a changing climate (Session: 15286)
Primary Convener: Tara W Hudiburg, University of Idaho, Forest, Rangeland, and Fire Sciences, Moscow, ID, United States Conveners: Philip E Higuera1, Kristina J Anderson-Teixeira2 and Alan J Tepley2, (1)University of Montana, Ecosystem and Conservation Sciences, Missoula, MT, United States (2) Smithsonian Institution, Front Royal, VA, United States.

Climate change and disturbance are two of the major forces shaping the dynamics of forests worldwide. Their interactive effects can be particularly consequential; climate change is expected to impact the frequency and intensity of disturbances, including drought, bark beetle outbreaks, and wildfires. Moreover, climate change may alter the resilience of forests to such disturbances, in some systems potentially resulting in shifts to alternative ecosystem states or trajectories. The result will be alteration of forest composition, biogeochemistry, and interactions with the climate system on scales ranging from single trees to biomes and from minutes to millennia. Anticipating the impacts of these changes requires both empirical and modeling studies that link mechanistic processes across spatial and temporal scales.

This session will include research incorporating current, paleo ecological, modeling, or data-model integration studies to answer critical questions concerning disturbance and climate interactions in forest ecosystems across a range of spatial and temporal scales.

Floods Working Group - H42E: Shifting Extremes: Understanding Hydrological Events for Societal Benefit (Session: 18367)
Conveners: Seyedehzahra Samadi, University of South Carolina, Columbia, SC, United States, Stacey Archfield, United States Geological Survey, Reston, VA, United States, Michaela Bray, Cardiff University, Cardiff, Wales, UK, and Scott St George, University of Minnesota, Minneapolis, MN, United States.

The challenges that hydrological extremes pose to sustainable development around the world are severe and growing, underscoring the need to better characterize the mechanisms that modulate exceptional events (including intense rainfall, floods, and droughts). The session welcomes contributions using hydrological and climate models, remote sensing, in-situ observations, and proxy evidence to explore several crucial questions. First, how is the multifaceted character of extremes (including persistence, clustering, and their compound nature) influenced by climate and land-use change? Second, what is the space-time structure of extremes and how do these characteristics influence their predictability? Third, how can hypothesis testing, diagnostics, and model development help us to better quantify uncertainty in extreme prediction? And finally, how can adaptation strategies help us reduce the societal consequences of hydrological extremes? In sum, we aim to bring together hydrologists, climatologists, geologists, and paleoclimatologists working to understand changes in hydroclimatic extremes at watershed, regional, or global scales.

DICE - PP34A: Aerosols, Clouds and Paleoclimate (Session: 17393)
Primary Convener: Nav Sagoo, Yale University, New Haven, CT, United States. Conveners: Natalie Burls, George Mason University Fairfax, Fairfax, VA, United States, Gisela Winckler, Lamont-Doherty Earth Observatory, Palisades, NY, United States and Trude Storelvmo, Yale University, New Haven, CT, United States.

Aerosol and cloud radiative forcings are responsible for the large uncertainty in the overall radiative forcing over the industrial period and limit our ability to constrain climate sensitivity, but their role in paleoclimates has received limited recognition. Natural aerosols such as dust, sea-salt, ash, soot and emissions from vegetation have undoubtedly varied in Earth history, impacting radiative processes in the atmosphere, cloud formation (direct and indirect effects) and hydrological processes.

We welcome data and model contributions that consider changes in the magnitude and variability of natural aerosols and or cloud processes at all timescales (millennial to long-term). We aim to facilitate discussions between the modeling and data communities in how best to move forward in constraining pre-industrial 'pristine' climate sensitivity to aerosols and clouds, as well as move beyond CO2 forcing and temperature comparisons in improving our understanding of proxy reconstructions and model-data comparisons.

2k Network - PP51E: Climate of the Common Era (Session: 17402)
Primary Convener: Jason E Smerdon, LDEO of Columbia University, Palisades, NY, United States. Conveners: Kevin J Anchukaitis, Woods Hole Oceanographic Institution, Woods Hole, MA, United States, Kim M Cobb, Georgia Institute of Technology Main Campus, Earth and Atmospheric Sciences, Atlanta, GA, United States and Edward R Cook, Lamont -Doherty Earth Observatory, Palisades, NY, United States.

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 focus on developing improved quantitative estimates of uncertainty are particularly welcome.

The session will emphasize improved estimates of past climate variability and associated atmosphere-ocean dynamics over the Common Era. New means of observing and reconstructing climate, as well as model-data comparisons over the Common Era that focus on regional or global-scale climate variability at resolutions of seasons to centuries are encouraged.

PALSEA2 working group - PP44A: Ice-sheet and sea-level variability during late-Cenozoic warm periods (Session: 17432)
Primary Convener: Anders E Carlson, Oregon State University, Corvallis, OR, United States. Convener: Glenn A. Milne, University of Ottawa, Ottawa, ON, Canada.

The behavior of ice sheets and their impact on sea level during late Cenozoic warm periods provides important information on the natural variability of ice sheets when they were in a similar configuration as today. As part of the Paleo Constraints on Sea level rise 2 (PALSEA2) PAGES/INQUA working group, this session aims to consider what the paleo record can say about rates, sources and processes of sea-level change during past warm periods such as the Holocene, the last interglaciation, other interglaciations, and the Pliocene optimum, and transitions into and out of these warm periods.

We seek contributions that draw on evidence from geologic records, and models of climate, ice sheets and glacial isostatic effects. Contributions are encouraged to synthesize results in a broader context, integrate diverse methodologies and data sources, and identify potential paths towards reconciling existing datasets and/or filling gaps in understanding past ice-sheet and sea-level behavior.

Arctic2k - PP11C: Polar hydroclimate in a paleoclimate context: current understanding and future challenges (Session: 14150)
Primary Convener: Hans W Linderholm, University of Gothenburg, Gothenburg, Sweden. Conveners: Jostein Bakke1, Björn E Gunnarson2 and Oyvind Paasche1, (1) University of Bergen, Bergen, Norway (2) Stockholm University, Stockholm, Sweden.

The impact of Polar hydroclimate change is not only local, but also global through various feedbacks and teleconnections. However, a lack of spatiotemporal observations makes quantification and understanding of Polar hydroclimate difficult. Paleoclimate proxies can provide more holistic views of past hydroclimate in these regions. Moreover, new methods enable tracking of both amount and source of local precipitation. Progress in the use of isotopes and other proxies have enhanced our understanding of how major shifts in atmospheric circulation patterns affected hydroclimate in the past. Also, co-development of numerical approaches, successfully integrating models and experimental data, has made it possible to link hydroclimate variability to shifts in the atmospheric water cycle in a long-term context.

This session aims at highlighting recent progress on Polar and Subpolar hydroclimate in a paleoclimate context, bringing together proxies, data syntheses and model simulations. Contributions exploring the mechanisms behind Polar hydroclimate variability are particularly welcome.

PlioVAR working group - PP31E: Reconstructing and modeling late Pliocene climate variability (Session: 17792)
Primary Convener: Erin McClymont, University of Durham, Durham, United Kingdom. Conveners: Natalie Burls, George Mason University Fairfax, Fairfax, VA, United States and Heather L Ford, Lamont -Doherty Earth Observatory, Palisades, NY, United States.

The Pliocene epoch (~2.6-5.3 million years ago) is arguably the best-resolved example of a climate state in long-term equilibrium with current or predicted near-future atmospheric CO2 concentrations. It was characterized by a warmer climate globally, reduced continental ice volume, and reduced ocean/atmosphere circulation intensity. Pleistocene paleoclimate studies have demonstrated the value of understanding climate variability on orbital timescales, whereby the unique spatial and temporal signatures of individual interglacials or glacial-interglacial cycles highlight sensitive regions or climate systems. Recent modeling work confirms that such variability (and regional non-synchronicity) should also be expected in the Pliocene.

As part of the PAGES PlioVAR working group, this session welcomes submissions which reconstruct and/or model mid and late Pliocene climates and environmental responses. Contributions investigating marine and terrestrial environmental change, ice-sheet behaviour, biotic responses and/or biogeochemical cycling are encouraged, so as to better understand climate forcings and feedbacks through both data analysis and data-model integration.

Two invited speakers have been confirmed: Naomi Levin (University of Michigan) and Kira Lawrence (Lafayette College).
