We live in unprecedented times - the Anthropocene - defined by far-reaching human impacts on the natural systems that underpin civilisation. Planetary Health explores the many environmental changes that threaten to undermine progress in human health, and explains how these changes affect health outcomes, from pandemics to infectious diseases to mental health, from chronic diseases to injuries. It shows how people can adapt to those changes that are now unavoidable, through actions that both improve health and safeguard the environment. But humanity must do more than just adapt: we need transformative changes across many sectors - energy, housing, transport, food, and health care. The book discusses specific policies, technologies, and interventions to achieve the change required, and explains how these can be implemented. It presents the evidence, builds hope in our common future, and aims to motivate action by everyone, from the general public to policymakers to health practitioners.
This paper examines vernacular weather observations amongst rural people on Sakhalin, Russia’s largest island on the Pacific Coast, and their relationship to the ice. It is based on a weather diary (2000–2016) of one of the local inhabitants and fieldwork that the author conducted in the settlement of Trambaus in 2016. The diary as a community-based weather monitoring allows us to examine how people understand, perceive and deal with the weather both daily and in the long-term perspective. Research argues that amongst all natural phenomena, the ice is the most crucial for the local inhabitants as it determines human subsistence activities, navigation and relations with other environmental forces and beings. People perceive the ice as having an agency, engage in a dialogue with it, learn and adjust themselves to its drifting patterns. Over the past decade, the inability to predict the ice’s behaviour has become a major problem affecting people’s well-being in the settlement. The paper advocates further integrating vernacular weather observations and their relations with natural forces into research on climate change and local fisheries management policies.
In September 1909 Captain Scott announced his intention to utilise dog transport in his dash for the Pole - this being his intention until as late as February 1911. In May 1911, Scott lectured expedition members about a new plan for their Southern Journey. His lecture notes include detailed calculations, based solely on ponies and men hauling the sledges – dogs and motor sledges were now surplus to requirements. In less than three months, Scott had supplanted his published scheme of advance. This article investigates evidence relating to Scott’s change of mind. A substantial amount of research has been undertaken and a credible explanation emerges. The First Depot Journey, with its loss of ponies, inadequate animal nutrition (both dogs and ponies) and crevasse incident wrecked Scott’s original scheme of advance. When he commenced detailed planning in April 1911, it became apparent his dogs could not reach the Pole. Scott’s leadership technique for getting his men to understand and support the new transport plan is examined and its influence on current perceptions of the expedition and its men is investigated.
Salt marshes are highly dynamic and important ecosystems that dampen impacts of coastal storms and are an integral part of tidal wetland systems, which sequester half of all global marine carbon. They are now being threatened due to sea-level rise, decreased sediment influx, and human encroachment. This book provides a comprehensive review of the latest salt marsh science, investigating their functions and how they are responding to stresses through formation of salt pannes and pools, headward erosion of tidal creeks, marsh-edge erosion, ice-fracturing, and ice-rafted sedimentation. Written by experts in marsh ecology, coastal geomorphology, wetland biology, estuarine hydrodynamics, and coastal sedimentation, it provides a multidisciplinary summary of recent advancements in our knowledge of salt marshes. The future of wetlands and potential deterioration of salt marshes is also considered, providing a go-to reference for graduate students and researchers studying these coastal systems, as well as marsh managers and restoration scientists.
This paper discusses weather observations of Moravian missionaries in Greenland in the long 18th century, placing them in the broader context of their missionary work at Neu-Herrnhut and other stations as well as their comments on the natural world. Some of their climate-related remarks and measurements were published and discussed in print, notably in David Cranz’ History of Greenland and a number of scholarly reviews at the time. These publications are compared to and complemented by data retrieved by the authors from unpublished source material in the Moravian Archives in Herrnhut, Germany, demonstrating that the Moravian diaries can fill in significant gaps in Greenland’s weather charts before systematic measurements were introduced in the 19th century. Their special interest for climate studies is underscored in conclusion, in particular their observations of extreme climate events that can allow us to better characterise the amplitude and geographical extent of such events and to compare them with climate model simulations in order to better understand the respective roles of external (volcanism, solar activity) and internal (atmospheric circulation) forcings and the impacts of potential feedbacks within the ocean–atmosphere system.
Place names serve a symbolic function in enforcing colonial power over landscapes. Within colonial locales, place names reproduce and reflect the ideological goals of settlers to reinforce or claim space for an individual, group or nation. One toponymically understudied colonial region where place names play a prominent role is the Antarctic, where the names of research bases promote the cultural power of settler nations to symbolically claim the continental landscape. As Antarctica is a geopolitically contested space, Antarctic research base names serve as an ideological purpose in reinforcing claims to the Antarctic, contrasting the ostensibly scientific purpose of research bases. This paper examines Antarctic research base names by categorising and interpreting their naming sources through a critical toponymic lens. This paper discusses general Antarctic naming trends and establishes possible reasons and outcomes of their employment, using three primary arguments: (1) Antarctic research base names are often nationalistic and reflect the implicit geopolitical goals of settler nations, (2) Antarctic research base names reflect and reproduce ongoing polar colonialism and (3) contestation over the naming of Antarctic research bases exemplifies the iconographical and cultural conflict between Antarctic nations. This paper seeks to provoke a future toponymic investigation into Antarctica and study Antarctic cultural landscapes more generally.
The use of Spratt’s dog cakes is well documented in the diaries and reminiscences of many early Antarctic expedition members. Commercially produced dog food was promoted by the likes of Spratt’s as an advanced form of animal nutrition and would have been of interest to expedition planners who were already concerned with the nutritional requirements of expedition members. An approximately 100-year-old dog cake recovered from Antarctica was compared by chemical analysis and spectroscopic methods with a series of model dog cakes and a commercial dog biscuit to determine the composition and calorific content. The presence of bone fragments within the dog cake was confirmed, whereas starch in the bulk matrix of the sample was consistent with being a mixture of wheat and oat flour, while only minimal fat or oil was present. Calorific content, while insufficient compared to a modern feed for high-performance dogs, would nonetheless have been a valuable addition to the use of dried or frozen whole meat such as seal, fish, or pemmican and contributed additional energy compared to meat alone.
After completing the steps in Chapter 7, I now have a well-prepared data set of monthly averaged atmospheric CO2. The placeholders have been removed and the gaps have been filled. I can now proceed to answer my original question:
Once you have a preliminary research question, it is time to investigate the existing data that could be used to address the question. To find existing data, start by searching the published peer-reviewed literature. Google Scholar or an open web search will not necessarily limit your search to peer-reviewed publications and can therefore be a waste of time or cause you to rely on inappropriate work, or both. The easiest way to find peer-reviewed science is to use a database at your institutional library that curates peer-reviewed publications. There are many databases that are useful. Web of Science is one of the most general useful databases, but you can also use databases that are more discipline specific like Georef or BioMed. Ask your librarians for advice to ensure that you are accessing the right papers for your purpose.
A good scientific question will motivate a good research project. The process of asking questions and gaining knowledge is iterative. Asking a question directs an action: an investigation into what has been done in this field before and what is already known about this problem. Sometimes the answer to your question can be found in the published scientific literature. If that is the case, you can refine your question. Answering a question generates new knowledge, which in turn generates new questions, and so on. So your questions will become clearer and more useful as you gain information, resources, and experience in your field. Be prepared to review your research questions regularly. They may need to change over time.
