The causes of ice ages are not fully understood for either the large-scale ice age periods or the smaller ebb and flow of glacial–interglacial periods within an ice age. The consensus is that several factors are important: atmospheric composition, such as the concentrations of carbon dioxide an...
This latter observation reveals that enhanced TC activity was synchronized with increased Asian dust emissions during the Little Ice Age. TC activity was also lower in the late Roman Warm Period, when SST was higher but Asian dust emissions were lower than in the early phase. Such patterns ...
Graham Hancock a journalist and author who for over 30 years has explored the controversial possibility that there existed a lost civilization during the last Ice Age, and that it was destroyed in a global cataclysm some 12,000 years ago. He is the presenter of the Netflix documentary series ...
During glacial MIS 8 and the stadials within MIS 7 and 5, glaciation did not extend as far as during MIS 2 and 6 (Fig. 3) and so cold air outbreaks, winter monsoon intensity and aridity was not sufficient to drive such dune expansion and dust deflation. Our revised age model and ...

1). The neodymium isotopic composition of terrigenous sediment is a powerful tracer for geographical provenance; it reflects to a large extent the mean age of the corresponding source region and is preserved during erosion and transport processes (Goldstein and Jacobsen, 1988). In this study we ...
5). Section 6 is a critical evaluation of the reliability of the methods applied, followed by discussion and conclusions in Sects. 7 and 8. 2 Sea Ice Decline Sea ice in the Arctic can be characterized by areal extent, thickness, age, and movement. The conditions on top of sea ice, ...

The International Commission on Stratigraphy (ICS) utilises benchmark chronostratigraphies to divide geologic time. The reliability of these records is fundamental to understand past global change. Here we use the most detailed luminescence dating age mo
