High-resolution late-glacial chronology for the Gerzensee lake record (Switzerland): δ18O correlation between a Gerzensee-stack and NGRIP

Oxygen-isotope variations were analyzed on bulk samples of shallow-water lake marl from Gerzensee, Switzerland, in order to evaluate major and minor climatic oscillations during the late-glacial. To highlight the overall signature of the Gerzensee δ18O record, δ18O records of four parallel sediment cores were first correlated by synchronizing major isotope shifts and pollen abundances. Then the records were stacked with a weighting depending on the differing sampling resolution. To develop a precise chronology, the δ18O-stack was then correlated with the NGRIP δ18O record applying a Monte Carlo simulation, relying on the assumption that the shifts in δ18O were climate-driven and synchronous in both archives. The established chronology on the GICC05 time scale is the basis for (1) comparing the δ18O changes recorded in Gerzensee with observed climatic and environmental fluctuations over the whole North Atlantic region, and (2) comparing sedimentological and biological changes during the rapid warming with smaller climatic variations during the Bølling/Allerød period. The δ18O record of Gerzensee is characterized by two major isotope shifts at the onset and at the termination of the Bølling/Allerød warm period, as well as four intervening negative shifts labeled GI-1e2, d, c2, and b, which show a shift of one third to one fourth of the major δ18O shifts at the beginning and end of the Bølling/Allerød. Despite some inconsistency in terminology, these oscillations can be observed in various climatic proxies over wide regions in the North Atlantic region, especially in reconstructed colder temperatures, and they seem to be caused by hemispheric climatic variations.

CAP Reform vs WTO: Crop Diversification or Crop Rotation? : Legal opinion prepared by Dr. Christian Häberli at the request of APRODEV, the Association of World Council of Churches related Development Organisations in Europe

The European Commission’s proposals for the Legislative Framework of the Common Agricultural Policy (CAP) in the period 2014-2020 include, inter alia, the introduction of a “strong greening component”. For the first time, all EU farmers in receipt of support are to “go beyond the requirements of cross compliance and deliver environmental and climate benefits as part of their everyday activities crop diversification as a contribution to all EU farmers in receipt of support go beyond the requirements of cross compliance and deliver environmental and climate benefits as part of their everyday activities.” In a legal opinion prepared at the request of APRODEV, the Association of World Council of Churches related Development Organisations in Europe (www.aprodev.eu), Christian Häberli examines the WTO implications of this proposal, as compared with an alternative proposal to rather link direct payments to crop rotation. The conclusions are twofold: 1. Crop rotation is at least as likely to be found Green Box-compatible as crop diversification. Moreover, it will be more difficult to argue that crop diversification is “not more than minimally production-distorting” because it entails for most farmers less cost and work. 2. Even if (either of the two cropping schemes) were to be found “amber”, the EU would not have to relinquish this conditionality. This is because the direct payments involved would in all likelihood not, together with the other price support instruments, exceed the amount available under the presently scheduled maximum.

Imagery of Early Christian Rituals in the Greek Physiologus

The paper focuses on the imagery of early Christian rituals (esp. of the eucharist and baptism) as they are found in allegorical interpretations of beasts in the Greek Physiologus and trace the way of selected motifs from the New Testament to this first Christian interpretation of nature in context of early Christian literature and theology. A special attention is given to the pelican, which is one of the most famous symbols of the eucharist, and to impressive baptismal imageries in the chapter on the eagle, on the snake and in some other chapters. The aim of the analysis is to explore the theological roots of the ritual imagery of Physiologus and to show that this work of early Egyptian Christianity is anything but 'unsakramental' as argued by E. Peterson (1959).

Christian-Muslim Relations. A Bibliographical History Volume 6: Western Europe (1500-1600)

Christian-Muslim Relations. A Bibliographical History, volume 6 (CMR 6), covering the years 1500-1600, is a continuing volume in a history of relations between followers of the two faiths as it is recorded in their written works. Together with introductory essays, it comprises detailed entries on all the works known from this century. This volume traces the attitudes of Western Europeans to Islam, particularly in light of continuing Ottoman expansion, and early despatches sent from Portuguese colonies around the Indian Ocean. The result of collaboration between numerous leading scholars, CMR 6, along with the other volumes in this series, is intended as a fundamental tool for research in Christian-Muslim relations.
