EGU 2016. Recognizing and understanding the couplings between glacial cycles and the solid Earth
*****************************************************************************************************
Dear colleagues,
Please consider submitting to this cross disciplinary session at EGU 2016. This session will be an occasion to discuss the links between surface dynamics, magmatism and volcanism.

ABSTRACT
Glacial
cycles affect the processes through which water and rocks are
redistributed across the Earth's surface, thereby linking the solid
Earth and
climate dynamics. The magma productivity is sensitive to pressure
variations and therefore submarine and subaerial magmatic, volcanic and
hydrothermal activity can be affected by glacial cycles and associated
changes in continental ice load, sea level and
surface denudation rates by erosion. In turn, emissions of solid
aerosols and volatiles from the solid Earth modulate the climate system
and therefore influence all processes involved with glacial-interglacial
oscillations. Existing observational and modelling
evidence about these linkages elicited controversy and further
couplings amongst the cryosphere, atmosphere or geo-biosphere may still
be unrecognized.
Exploration of these feedbacks is timely and promising in terms of
societal and academic impact for it involves key factors related to
climate change and tectonics, management of the territory and hazard
assessments in fast-evolving and high-potential/risk
environments such as glaciated, volcanic, tectonically active and
hydrothermal terrains. Beyond this, recognizing and understanding the
mutual forcing between climate, surface processes and the solid Earth
dynamics, including the likely interactions with the
human activity, is fundamental to apprehend the functioning of the
Earth system as a whole and improve our living conditions within it.
With the aim of advancing the debate on the mass and energy fluxes
across the Earth system, this session invites contributions pertaining
to the recognition and understanding of the couplings between climate
and the solid Earth dynamics through all kind of
modelling and observations. Emphasis will be put on modern tools and
interdisciplinary investigations, addressing the interactions between
glacial processes, sea level change, sediment supply, landscape
evolution and the volcanic, hydrothermal and tectonic
activity on glacial/interglacial timescales. However, contributions
about other linkages or more specific aspects of the Earth system
evolution at all timescales relevant to glaciation are also welcome.
