John Lewis Gaddis doceert militaire- en politieke strategie aan de Yale University en wordt gezien als de meest vooraanstaande historicus over de Koude Oorlog. In zijn recente studie over Herodotus, Sun Tzu, Von Clausewitz en andere grote strategen probeert de Amerikaan uiteen te zetten waarom bepaalde leiders succesvol waren en andere niet.

Reviews on whole body human cold adaptation generally do not distinguish between population studies and dedicated acclimation studies, leading to confusing results. Population studies show that indigenous black Africans have reduced shivering thermogenesis in the cold and poor cold induced vasodilation in fingers and toes compared to Caucasians and Inuit. About 40,000 y after humans left Africa, natives in cold terrestrial areas seems to have developed not only behavioral adaptations, but also physiological adaptations to cold. Dedicated studies show that repeated whole body exposure of individual volunteers, mainly Caucasians, to severe cold results in reduced cold sensation but no major physiological changes. Repeated cold water immersion seems to slightly reduce metabolic heat production, while repeated exposure to milder cold conditions shows some increase in metabolic heat production, in particular non-shivering thermogenesis. In conclusion, human cold adaptation in the form of increased metabolism and insulation seems to have occurred during recent evolution in populations, but cannot be developed during a lifetime in cold conditions as encountered in temperate and arctic regions. Therefore, we mainly depend on our behavioral skills to live in and survive the cold.
The ongoing environmental changes in the Arctic call for a deeper understanding of how local communities experience and adapt to these transformations. This PhD examines sense of place and how this shapes future climate imaginaries within riverine communities, focusing on the Altaelva community in northern Norway. In northern Peru, the community has long experienced alternating environmental changes due to the El Niño Southern Oscillation, nowadays intensified by climate change. By examining how these communities adapt to cyclical environmental shifts, this case study provides comparative insights relevant to the Arctic, where climate change presents a more linear, continuous impact.Utilizing qualitative methods, I explore how individuals and groups form emotional and cognitive attachments to the environment while living in a changing climate. This PhD investigates locally rooted visions of climate futures that are informed by the community's sense of place, so-called “emplaced climate imaginaries”. By focusing on how the community’s attachment to the river influences their perceptions of future climate scenarios, I aim to identify the ways in which these imaginaries contribute to sustainable adaptation strategies.The study’s focus on the intersection of emotional bonds to place and anticipatory climate futures offers insights into how communities cope with and adapt to environmental change. These findings will contribute to broader discussions on climate resilience, emphasizing the importance of integrating local narratives and experiences into climate adaptation policies. The research not only provides a lens into Arctic futures but also underscores the role of local, place-based attachments in shaping responses to climate change.
