The GCCA6 conference was successfully held on December 12th and 13th, 2005 in the Mirai-CAN Hall, Miraikan, Tokyo.  Global climate changes are an urgent problem facing the world today. Current studies have suggested that the Arctic plays a crucial role in climate changes.  The goals of this conference are to (a) integrate our understanding of the role of the Arctic through investigations of complex feedback processes in the Arctic system composed of atmosphere, ocean, hydrosphere, biosphere, cryosphere, and tectonic activities, (b) organize international collaborations in Arctic researches, and (c) attract public interests in the role of the Arctic in global climate changes. We had two special sessions: International Collaborations for Arctic Environmental Change Research over the Next Decade and IPY (International Polar Year) 2007 - 2008. Papers for 8 general sessions were presented by posters. 84 scientists including 20 students attended (10 from foreign countries). Mr. Takahiro Iida (Graduate School of Fisheries Sciences, Hokkaido University) won the best student poster award. Dr. Mamoru Mohri, Executive Director of Miraikan also participated and many lively discussions on global environmental changes, especially on the Arctic changes have been done. There also have been public lectures in the afternoon of Dec. 12. Prof. Shun-Ichi Akasofu (Director of International Arctic Research Center, University of Alaska, Fairbanks) and Prof. Masami Fukuda (Institute of Low Temperature Science, Hokkaido University) presented lectures for 50 general attendants and attendants for conference.

    The Arctic affects the global climate through strong feedback processes in the system, consisting of the atmosphere, ocean, hydrosphere, biosphere, cryosphere, and tectonic activities.  Previously, five GCCA conferences were held at Sendai in 2000, Sapporo in 2001, Fairbanks Alaska in 2002, Toyokawa in 2003, and Tsukuba in 2004. Through these conferences, crucial research topics were identified and the importance of integration efforts was recognized.

    The GCCA conferences have been organized by the International Arctic Research Center (IARC) at the University of Alaska Fairbanks (UAF) and member universities of the University Consortium for GCCA in Japan in order to study Arctic climate change, global warming, and to predict the future changes. Miraikan in Tokyo is an ideal location for the next conference, bringing together both Japanese and foreign scientists for the purpose of formulating joint projects in advancing our knowledge of the climate in the Arctic. The focus of this conference is (1) to integrate our understanding of the role of the Arctic in the global climate change in order to provide the perspective of the Arctic research for the next decade and (2) to formulate joint research projects between Japanese and world-wide researchers for the specific target of the International Polar Year (IPY) to be held in 2007 to 2008.

Scientific Sessions

              Special Sessions

              International Collaborations for Arctic Environmental Change Research over the Next Decade

                            Invited Speakers: A. Ohmura, L. Hinzman, Hiroshi L. Tanaka, and Mamoru Mohri

Existing climate models do not work well in the polar regions and have failed to predict recent accelerated warming. To understand the current global climate and what might happen in future, internationally collaborated campaigns of research in the Arctic and its surrounding regions are essential. This special session aims at promoting such international collaborations planned for the next decade.

              Research plans in IPY 2007 – 2008

                            Invited Speakers: Cynan Ellis-Evans, Robert Corell, and Jerry Brown

The International Polar Year (IPY) 2007-2008 is an intense, internationally coordinated campaign of research that will initiate a new era in polar science. The IPY will include research in both polar regions and recognize the strong links these regions have with the rest of the globe. This special session introduces the proposed IPY projects in the Arctic and their links with the IPY projects in the Antarctic.
