Earth System Science: Climate, Global Change and People
Open Science Conference, Edinburgh, 10-13 May 2010
The AIMES Open Science Conference will present recent advances in the understanding of Earth-system dynamics and highlight new directions in analysing the interactions between humans and their environment. It is intended the conference will help build bridges between the natural sciences, the social sciences and the humanities, and between policy, assessment and research.
The conference is co-sponsored by QUEST (Quantifying and Understanding the Earth System), a flagship research programme funded by the UK Natural Environment Research Council (NERC) during 2003-2010. The conference will address Earth system questions in the context of past, present and future global environmental changes. Building on the exceptional growth of cross-cutting research over the past 15 years, it will emphasise interdisciplinary synthesis and linkages: between observations and models, biodiversity and climate, the humanities, social and natural sciences, policy, assessment and research.
The conference will include a small number of invited keynote presentations, providing state-of-the art overviews of major topics, and a somewhat larger number of presentations selected from responses to the Call for Abstracts, which will be issued in September 2009. The poster sessions will form an integral, and important, part of the conference programme. Registration, travel and accommodation information will be available through the conference website, which will be made available together with the Call for Abstracts in September.

The conference will be structured around three broad themes.
First, Earth-system modelling: from observations and process understanding to prediction and risk assessment. Climate models have evolved to include interactions among atmospheric composition, biogeochemical cycles and the physical climate system. With this development has come the need to integrate understanding from many disciplines not traditionally linked to climate science. The application of models fulfils distinct objectives, including near-term climate forecasting, assessment of climate change impacts and risks, and quantifying the effects of climate policies. This theme will include recent advances in the integration of Earth system components in models, the application of diverse observations to evaluate and improve them, and the applications of models to project the consequences of different policy options for the physical, chemical and biological environment.
Second, dynamics of biogeochemical cycles and climate: transitions, instabilities and feedbacks. Natural archives attest to abrupt changes involving different aspects of the Earth system (physical and biogeochemical) apparently in response to smoothly varying forcing-the signature of a highly non-linear system. Concern is growing that human pressures could activate one or more of a host of potential positive feedbacks leading to an acceleration of climate change. The work needed to quantify feedbacks in the Earth System, based on observations and models, has only begun. This theme will deal with attempts to understand abrupt transitions in the past, and to move from speculation to prediction in assessing the risks of meeting thresholds and "tipping points" in the future.
Third, people and resources-perspectives on the relations among environment, ecosystems and human needs. Sufficient, secure and safe supplies of water, food and energy are key human needs that underpin the UN's Millennium Development Goals. But increasing pressures on the underlying natural resources-potentially compounded by climate change-are creating obstacles to their attainment. This theme will highlight the growing interdisciplinary field that strives to understand human-environment interactions through the concept of socio-ecological systems. This field aims to achieve an understanding both of the drivers of change in the use of land and marine resources, and the consequences of changing resource use patterns for ecosystem services and human well-being.
Some "golden threads" run through all themes.

IGBP's Global Analysis, Integration and Modelling (GAIM) Task Force, the precursor of the Analysis, Integration and Modelling of the Earth System (AIMES) project, held its Open Science Conference in 1995. Tremendous progress has taken place during the almost 15 years since then in the field of climate and environmental changes, their causes, and their impacts on natural and human environments, and on strategies for mitigation of and adaptation to climate change. The research landscape has changed drastically, while problems at the Earth System level-climate change above all-have catapulted to the top of the international policy agenda, presenting new challenges and a new urgency to Earth system science.
