Paul Bishop and the evolution of the Scottish Alliance of Geosciences, Environment and Society (Sages)
The Scottish Alliance of Geoscience, Environment and Society (SAGES) was launched in May 2007 and thrives to this day (https://www.sages.ac.uk). It is a major research partnership between ten institutions in Scotland squarely focused on the prime problem of our time, namely understanding how the natural world works and how it interacts with human society. The inspiration driving SAGES is that we can all contribute more if we collaborate. Paul Bis…
West Antarctic ice sheet and CO 2 greenhouse effect: A threat of disaster
Over 40 years ago, the glaciologist John Mercer warned that parts of the West Antarctic Ice Sheet were at risk of collapse due to the CO2 greenhouse effect. Mercer recognised the unique vulnerability of ice sheets resting on beds far below sea level (marine-based ice sheets), where an initial warming signal can initiate irreversible retreat. In this paper, we review recent work on evidence for ice sheet collapse in warmer periods of the recent ge…
Climate emergency: Lessons from the Covid-19 emergency
The COP-26 United Nations Climate Change meeting, scheduled to be held in Glasgow in 2021, is an important step in the world’s attempt to deal with the climate emergency arising from increasing greenhouse gas emissions. Here we look at how society has responded to the Covid-19 emergency and compare it with the response to the climate change emergency, the latter based on our experience of a Royal Society of Edinburgh Inquiry on climate change pub…

The East Antarctic Ice Sheet: Unstable Ice or Unstable Ideas
The Last Glaciation in Central Magellan Strait, Southernmost Chile
Glacial landforms and drift stratigraphy in central Magellan Strait, southernmost Chile, document repeated fluctuations during the last glacial cycle of outlet lobes from an ice cap centered over the southern Andes. The lobes developed comparatively low-gradient profiles because of low basal shear stresses over soft deformable beds and this made them sensitive to even small-scale changes in the mass balance. Such low profiles and rapid calving in…
Glacier Modeling and the Climate of Patagonia during the Last Glacial Maximum
Ice cap modeling constrained by empirical studies provides an effective way of reconstructing past climates. The former Patagonian ice sheet is in a climatically significant location since it lies athwart the Southern Hemisphere westerlies and responds to the latitudinal migration of climatic belts during glacial cycles. A numerical model of the Patagonian ice cap for the last glacial maximum (LGM) is developed, which is time-dependent and driven…

Modeling the Growth and Decay of the Antarctic Peninsula Ice Sheet
A model of the growth and decay of the Antarctic Peninsula Ice Sheet during the last glacial/interglacial cycle is used to identify the main controls on ice sheet behavior. Using as input glaciological assumptions derived by W. F. Budd and I. N. Smith (1982, Annals of Glaciology 3, 42–49), bedrock topography, isostatic compensation, and mass balance relationships, the model is driven by sea-level change over the last 40,000 yr in association with…
Late-Glacial and Holocene Glacier Fluctuations and Environmental Change on South Georgia, Southern Ocean
South Georgia provides a terrestrial record of postglacial environmental change from a largely oceanic zone of the Earth. The record is representative of the southern westerlies and provides a link between Antarctica and the temperate zones of southern South America. Evidence from glacial geomorphology, slope stratigraphy, and analyses of environmental indicators in peat and lake cores is used to interpret this record. Wastage of the full-glacial…

Striae and Former Ice-Flow Directions in Snowdonia, North Wales
There are two views concerning the mountains of Snowdonia and their role during former glaciations of Britain. One is that they formed a subsidiary centre for ice dispersal, while the second is that they were overrun by westward-flowing ice derived from the main Welsh ice centre in the east. In this paper striation directions are used to test the two hypotheses. The striation pattern reflects ice flow radiating from the general vicinity of Snowdo…

Late Quaternary Glacial History of George VI Sound Area, West Antarctica
During the last glacial maximum in West Antarctica separate ice caps developed on Alexander Island and on Palmer Land, became confluent in George VI Sound, and discharged northward from latitude 72° S. Radiocarbon (>32,000 yr) and amino acid (approximately 120,000 yr) age determinations on shell fragments ( Hiatella solida ) found in basal till suggest a Wisconsin age for the glaciation that incorporated them. The pattern of ice flow differed fro…

The Maximum Ice Extent on Island Groups in the Scotia Sea, Antarctica
Evidence is presented for a more extensive ice cover over South Georgia, the South Orkney Islands, the South Shetland Islands, and the tip of the Antarctic Peninsula. Ice extended across the adjacent submarine shelves to a depth of 200 m below present sea level. Troughs cut into the submarine shelves by ice streams or outlet glaciers and ice-scoured features on the shelf areas suggest that the ice caps were warm-based. The South Shetland Islands …

The Selectivity of Glacial Erosion in the Cairngorm Mountains, Scotland
THE CAIRNGORMS are a distinctive mountain group lying just north of the Dee headwaters in the north-eastern Grampian mountains. The granite summits include the second highest mountain in the British Isles, Ben Macdui, I3I0 m (4300 ft), while four others exceed an altitude of I220 m (4000 ft). Indeed, as the Kings Majesties water-poet, John Taylor, marvelled on his money-less perambulation in I6I8, 'Highgate Hill, Hampsted hill, Birdlip hill or Ma…
The Significance of Periglacial Activity on Some Scottish Mountains
There are differing views on the role of periglaciation in modifying upland landscapes in Scotland. This paper describes the periglacial phenomena in a single massif and discusses their relationships with glacial landforms. It is concluded that there has been relatively little downslope movement of regolith under periglacial conditions since the wasting of the last ice sheet; indeed, periglacial processes have done little more than create distinc…

Landforms of Deglaciation in the Cairngorm Mountains, Scotland
This paper attempts to reinterpret the landforms of deglaciation in the Cairngorm mountains. Most deglacial features are fluvioglacial in origin. Ice-directed meltwater channels and associated eskers are often discordant with the older relief and their orientation reflects the dominant direction of ice movement. On the floors of the glens (valley), valley-controlled fluvioglacial forms accord more closely with the underlying bedrock surface and r…

Structural Landforms: Landforms Associated with Granitic Rocks, Faults, and Folded Strata
Up to the end of last century, landforms were viewed largely as expressions of the structure of the earth's underlying crust. But such interpretations were concerned for the most part with generalities and broad effects; the subtleties of structural factors became overshadowed first by cyclic explanations and then by the modern emphasis on process and climatic geomorphology. This book arose from the neglect of structural factors in geomorphologic…
