The Antarctic continent and Southern Ocean are extremely important parts of the global physical/biological system, linked to the rest of the Earth in often highly non-linear ways. Research has shown that to understand how planet Earth works we need to study it increasingly as a system, and understand the lithosphere, the hydrosphere, the cryosphere, the biosphere and the atmosphere. One of the remotest parts of the Earth system is Antarctica, a continent larger than either Australia or Europe. We will not be able to fully understand how the Earth system works without comprehensive knowledge of the physical, biological, chemical and geological processes taking place within and above Antarctica and its surrounding Southern Ocean. That is a huge challenge given that these processes take place among some of the remotest and harshest environments anywhere on the Earth’s surface.

To understand how planet Earth works we study it increasingly as a system – a collection of interdependent parts or spheres – the lithosphere, the hydrosphere, the cryosphere, the biosphere and the atmosphere. Understanding how these spheres are connected and how they interact improves our ability to forecast how one or a combination of them may change in response to external forcings caused for example by the advent of volcanic eruptions, solar variability or human activities. One of the remotest parts of the Earth system is Antarctica, a continent larger than either Australia or Europe. We will not be able to fully understand how the Earth system works without comprehensive knowledge of the physical, biological, chemical and geological processes taking place within and above Antarctica and its surrounding Southern Ocean.

Much has been achieved in acquiring knowledge of Antarctica’s physical, biological, chemical and geological processes, especially since a network of permanent scientific stations was established for the first time on the continent during the International Geophysical Year of 1957-58. Many more results also emerged from the [http://www.ipy.org/ International Polar Year] of 2007-2008.

Currents and waves in the global ocean and the atmosphere ensure that Antarctica is affected by what happens elsewhere on the planet. Equally, ocean and atmospheric processes ensure that what happens in Antarctica may affect the rest of the world. It is the world’s freezer.

With the increasing emphasis on cross-disciplinary Antarctic studies in the early years of this century, [http://www.scar.org/ SCAR] started a series of regular meetings that focussed of developing better links between those working in the physical and biological sciences. Out of this grew an initiative that became known as Antarctic Climate Change and the Environment ([http://www.scar.org/othergroups/acce ACCE]), which was seem as a southern counterpart to the Arctic Climate Impact Assessment ([http://www.acia.uaf.edu/ ACIA]). The goal was to prepare a volume that reviewed our present understanding of the physical and chemical climate system of the Antarctic region, the way it varies through time, and the profound influence of that variation on life on land and in the ocean around the continent. It would also examine predictions of how the system would evolve over the next century under conditions of increasing concentrations of greenhouse gases and recovery of the ozone hole.

What we set out to do in this volume is to review present understanding of the physical and chemical climate system of the Antarctic region, the way it varies through time, and the profound influence of that variation on life on land and in the ocean around the continent. We then use this as the basis for predicting, albeit crudely within the limits of the dearth of information compared with the other continents, what may happen in the future as greenhouse gases build up in the atmosphere and as the ozone hole starts to diminish. This volume should be taken as a companion to the Arctic Climate Impact Assessment published in 2005.

The work has been carried out under the editorial control of representatives of three of SCAR&rsquo;s five major scientific research programmes: Antarctica in the Global Climate System (AGCS), Antarctic Climate Evolution (ACE), and Evolution and Biodiversity in the Antarctic (EBA). The process began in 2005 when the SCAR Executive Committee meeting in Sofia, Bulgaria (July 11-13, 2005) agreed that an Antarctic Climate Impact Assessment should be produced for the guidance of policy makers in the Antarctic Treaty System and to inform the public. The plan for the assessment was fleshed out at the first SCAR Cross-Linkages Workshop, in Amsterdam (November 15-17, 2005) (http://www.scar.org/researchgroups/crosslinkages/Amsterdam_Meeting_Report.pdf). Phase I focused on the physics of the climate system. The plans were presented to policy makers at the Antarctic Treaty Consultative Meeting in Edinburgh in 2006 (http://www.scar.org/treaty/atcmxxix/atcm<sup>2</sup>9_ip089.pdf). Initial results were presented to policy makers at the Antarctic Treaty Consultative Meeting in New Delhi in 2007 (http://www.scar.org/treaty/atcmxxx/Atcm<sup>3</sup>0_ip005_e.pdf) and published in the journal Reviews in Geophysics in January 2009 (Mayewski et al., 2009<ref name="Mayewski et al, 2009">Mayewski, P.A., Meredith, M.P., Summerhayes, C.P., Turner, J., Worby, A.P., Barrett, P.J., Casassa, G., Bertler, N.A.N., Bracegirdle, T.J., Naveira-Garabato, A.C., Bromwich, D.H., Campbell, H., Hamilton, G.H., Lyons, W.B., Maasch, K.A., Aoki, S., and Xiao, C. 2009. State of the Antarctic and Southern Ocean Climate System (SASOCS), ''Reviews of Geophysics'', '''47''', RG1003, doi:10.1029/2007RG000231.</ref>). In the meantime work had begun on Phase II, incorporating biology and chemistry, and preliminary results were presented to policy makers at the Antarctic Treaty Consultative Meeting in Kiev in 2008 (http://www.scar.org/treaty/atcmxxxi/ATCM31_IP62_ACCE.pdf), with final results being presented to the Antarctic Treaty Consultative Meeting in Baltimore in 2009 (http://www.scar.org/treaty/atcmxxxii/Atcm<sup>3</sup>2_ip005_e.pdf). A summary paper on the science is currently being prepared for the journal Antarctic Science.

Five hundred copies of the volume were published and distributed widely to the Antarctic community and beyond. In addition, individual downloadable chapters were made available on the SCAR web site, so as to encourage its widespread use as a research and teaching resource. The volume was a contribution to the International Polar Year 2007-2008 and to the goals of the World Climate Research Programme ([http://www.wcrp-climate.org/ WCRP]), and in particular to its Climate and Cryosphere programme ([http://www.climate-cryosphere.org/ CliC]), of which SCAR is a co-sponsor. It was also made available to attendees at the [http://unfccc.int/meetings/copenhagen_dec_2009/meeting/6295.php meeting of the UN Framework Convention on Climate Change in Copenhagen] in December 2009, and subsequently to the [http://www.ipcc.ch/ Intergovernmental Panel on Climate Change]. Brief, annual updates on advances in Antarctic climate-related science were also provided to the [http://www.ats.aq/e/ats_meetings_atcm.htm Antarctic Treaty Consultative Meetings]. However, Antarctic science is advancing very rapidly with important papers regularly being reported in the popular press. It was therefore felt that a revision to the original ACCE volume would be appropriate. But rather than produce another hardcopy book it was decided to convert the original material into a wiki so as to make it easier to revise the text.

There is a historical context to the development of the ACCE volume, which can be considered as an eventual outcome of the work of the SCAR Group of Specialists on Antarctic Climate Research formed in 1980 to plan the Antarctic contribution to the WCRP (then about to be formed). The first product of the Group was &ldquo;Antarctic Climate Research: Proposals for the Implementation of a Programme of Antarctic Research contributing to the World Climate Research Programme&rdquo;.

Following the recommendations of those reports SCAR created programmes such as Antarctic Sea Ice Processes and Climate (ASPeCt), Ice Sheet Mass Balance and Sea Level (ISMASS) and the International Trans-Antarctic Scientific Expedition (ITASE) to explore aspects of the physical and chemical elements of the climate system in the Antarctic. In parallel, SCAR developed programmes such as ANTOSTRAT to look at the geological history of climate change and the development of the ice sheet in the distant past, and SCAR biologists began working on EVOLANTA to examine the evolution of organisms through time in response to external forcings. With SCAR&rsquo;s reorganisation in 2004, the physical climate activities became absorbed into AGCS, the biological activities became absorbed into EBA, and the geological ones into ACE.

The Antarctic continent and Southern Ocean are extremely important parts of the global physical/biological system, linked to the rest of the Earth in often highly non-linear ways. Research has shown that to understand how planet Earth works we need to study it increasingly as a system, and understand the lithosphere, the hydrosphere, the cryosphere, the biosphere and the atmosphere. One of the remotest parts of the Earth system is Antarctica, a continent larger than either Australia or Europe. We will not be able to fully understand how the Earth system works without comprehensive knowledge of the physical, biological, chemical and geological processes taking place within and above Antarctica and its surrounding Southern Ocean. That is a huge challenge given that these processes take place among some of the remotest and harshest environments anywhere on the Earth’s surface.

Much has been achieved in acquiring knowledge of Antarctica’s physical, biological, chemical and geological processes, especially since a network of permanent scientific stations was established for the first time on the continent during the International Geophysical Year of 1957-58. Many more results also emerged from the International Polar Year of 2007-2008.

With the increasing emphasis on cross-disciplinary Antarctic studies in the early years of this century, SCAR started a series of regular meetings that focussed of developing better links between those working in the physical and biological sciences. Out of this grew an initiative that became known as Antarctic Climate Change and the Environment (ACCE), which was seem as a southern counterpart to the Arctic Climate Impact Assessment (ACIA). The goal was to prepare a volume that reviewed our present understanding of the physical and chemical climate system of the Antarctic region, the way it varies through time, and the profound influence of that variation on life on land and in the ocean around the continent. It would also examine predictions of how the system would evolve over the next century under conditions of increasing concentrations of greenhouse gases and recovery of the ozone hole.

Inputs were obtained through a process of open consultation with the wider community in which scientists affiliated with SCAR or known to be active in climate and environmental sciences in Antarctica or the Southern Ocean were asked for text on key topics. A first draft was then circulated to the wider community for comment in June 2008. The Editorial Board then modified the text for a second round of open consultation in March 2009.

Eventually over 100 scientists from various fields contributed to the volume, which was published in 2009 as Antarctic Climate Change and the Environment. They are listed alphabetically as authors of the appropriate chapters after the chapter editor.


Five hundred copies of the volume were published and distributed widely to the Antarctic community and beyond.
