Feedbacks of lithosphere dynamics and environmental change of the Cenozoic West Antarctic Rift System.
This special issue of Global and Planetary Change contains 11 contributions dealing with various aspects of the Cenozoic West Antarctic Rift System. During the last two decades, investigations of the interplay of tectonics and climate greatly improved understanding of Cenozoic global change. Major p...

This special issue of Global and Planetary Change contains 11 contributions dealing with various aspects of the Cenozoic West Antarctic Rift System. During the last two decades, investigations of the interplay of tectonics and climate greatly improved understanding of Cenozoic global change. Major plate reorganizations in the Southern Hemisphere, starting with the breakup of Gondwana in the Mesozoic, were a key factor in the thermal isolation of Antarctica and the initiation of the East and West Antarctic Ice Sheets, which, in their turn, influenced lower latitude and Northern Hemisphere climates with the oceans as intermediaries. Recent studies are increasingly drawing attention to the tectonic effects in glaciated rifts and rifted margins. During the Pleistocene, the rifted margins around the North Atlantic repeatedly were the core regions for continental ice sheet expansions. However, as demonstrated by recent work, Cenozoic uplift of the Norwegian margin started as early as 30 Ma. Similarly, from the early Oligocene onwards, topographic uplift of the Transantarctic Mountains, the western flank of the Cenozoic West Antarctic Rift System, triggered the formation of local ice centres which merged to form large ice sheets.
