REKLIM Special Issue in POLARFORSCHUNG

Dear participants of the REKLIM conference, der colleagues, As a follow up of our October 2014 international REKLIM conference “Our Climate – Our Future; regional perspectives on a global challenge” we compiled a special issue in the journal POLARFORSCHUNG (Polar Research), published by the German Society of Polar Research (www.dgp-ev.de) and the Alfred Wegener Institute Helmholtz Center for Polar and Marine Research (AWI). More than 70 authors in 14 papers contributed to this special issue, providing a wide range of current understanding and knowledge about the different aspects of regional climate change, its causes, impacts and challenges. Mainly themes from topics 1, 2, 3 and 8 were covered by papers, ranging from modelling of the regional climate system to general process understanding, from data analysis to the development of data bases and associated web-based infrastructures, making scientific knowledge and data available for research and the wider public. The order of the papers is organized according to their contextual contribution to the conference topics. Herewith we thank all contributors to this conference volume. Their abiding patience is most appreciated. Twenty-three reviewers from eight countries contributed substantially to the quality of this special issue. Their efforts have been invaluable to improving the scientific content and integrity of the papers. Several agencies and governments supported the data acquisition and analysis, including the arrangement of the conference. Here, especially the Helmholtz Association needs to be mentioned, which fostered the initiation and funding of the Helmholtz Climate Initiative REKLIM. Best regards,
Klaus Grosfeld List of contents:
