Long-term environmental change in Co. Mayo, on the mid-Atlantic seaboard of Ireland, is discussed. Pollen diagrams and bog pine, dated by ¹⁴C and dendrochronology, provide evidence for woodlands, farming and climate change. Intensive farming is dated to the early Neolithic (3800–3400 BC) prior to wide-scale spread of blanket bog. Construction of the peat-covered, stone-wall field system at Céide Fields occurred at this time which is unexpectedly early. Bronze and Iron Age activity is detailed.

Late Pleistocene Yedoma deposits of Siberia and Alaska are prone to degradation with warming temperatures. Multimodal grain-size distributions of >700 samples indicate varieties of sediment production, transport, and deposition. These processes were disentangled using robust endmember modeling analysis. Nine robust grain-size endmembers characterize these deposits. The data set was finally classified using cluster analysis. The polygenetic Yedoma origin is proved.

The Black Forest was covered by a 1000 km² large ice cap during the last glaciation. Glacial landforms in the area north-west of the highest summit of the Black Forest, the Feldberg (1493 m above sea level), were investigated to select suitable sampling sites for dating glacial landforms in future studies. Some of the terminal moraines described in this study are mapped for the first time. The application of dating methods will provide insights into the chronology of the last glaciation.
