Surficial geology and geomorphology of Greg crater, Promethei Terra, Mars
Greg crater, located in Promethei Terra, Mars is a ∼66 km diameter impact crater. The crater has been widely studied, both in terms of its overall geomorphological evolution and, more specifically, its ice-rich landforms. One category of these, glacier-like forms, appears to be closely analogous to valley glaciers on Earth. However, Greg crater hosts many other features, the origins and inter-relationships between which are of continuing interest…
Structural glaciology of Isunguata Sermia, West Greenland
We present a 1:42,000 scale map of Isunguata Sermia, a land-terminating outlet glacier draining the western-sector of the Greenland Ice Sheet. Structure-from-Motion software applied to ∼3,600 aerial images collected by a fixed-wing unmanned aerial vehicle in July 2015 allowed us to produce a high resolution (0.3 m ground sampling distance (GSD)) orthomosaic and digital elevation model (DEM; 1.5 m GSD).These products were used to map and describe …
Glaciological and geomorphological map of Glacier Noir and Glacier Blanc, French Alps
This paper presents and describes a glaciological and geomorphological map of Glacier Noir and Glacier Blanc, French Alps. Glacier Noir is a debris-covered glacier and is adjacent to Glacier Blanc, a clean-ice (debris-free) glacier. The glaciological and geomorphological evolution of Glacier Blanc is well known, but the evolution of Glacier Noir is poorly understood, as is the case for many debris-covered glaciers globally, despite their importan…
Political radicalization on the Internet
The role of the internet in radicalizing individuals to extremist action is much discussed but remains conceptually and empirically unclear. Here we consider right-wing and jihadist use of the Internet – who posts what and where. We focus on extremist content related to radicalization to violent action, and argue that victim videos and jihad videos are particularly powerful in moving individuals to radical action. We interpret these two kinds of …
The structural glaciology of southwest Antarctic Peninsula Ice Shelves (ca. 2010)
The Antarctic Peninsula has recently seen a rapid breakup of its peripheral ice shelves, attributed to atmospheric and oceanic warming in the region. Previous work has illustrated that the final breakup mechanisms are often controlled by the structural glaciology of the ice shelf, and thus understanding the structure of the remaining ‘stable’ ice shelves is of fundamental importance to assess their future response to continued environmental chang…
The Direct Impact of Climate Change on Regional Labor Productivity
Global climate change will increase outdoor and indoor heat loads, and may impair health and productivity for millions of working people. This study applies physiological evidence about effects of heat, climate guidelines for safe work environments, climate modeling, and global distributions of working populations to estimate the impact of 2 climate scenarios on future labor productivity. In most regions, climate change will decrease labor produc…
Late-Holocene North Atlantic climate ‘seesaws’, storminess changes and Greenland ice sheet (Gisp2) palaeoclimates
The oxygen-isotope record of palaeotemperature from Greenland ice cores has for many years been the kingpin of climate reconstructions for the North Atlantic region and northern Europe. An air temperature ‘seesaw’ between Greenland and northern Europe, first described in AD 1765, is also well known and is related to the North Atlantic Oscillation (NAO). Whereas the NAO index series is based on instrumental records of air pressure, the North Atlan…
Complex North Atlantic Oscillation (NAO) Index signal of historic North Atlantic storm-track changes
Previous reports have suggested a link between increased storminess in the North Atlantic during recent years with a period of time during which the North Atlantic Oscillation Index has been strongly positive. New analyses of late nineteenth-century gale-day data for meteorological stations in northern Scotland and western Ireland indicate that the relatively high storminess that characterized this period was associated with monthly NAO Index val…
