Increased levels of greenhouse gases released into the atmosphere, a legacy of the industrial revolution, population growth pressures, and consumerist lifestyle choices, are the main contributors to human-induced climate change. Climate change is commensurate of warming temperatures, reductions in rainfall, increased frequency of extreme weather events, and contributions toward declining public health trends. Green Infrastructure (GI) presents diverse opportunities to mediate adverse effects, while simultaneously delivering human health, well-being, environmental, economic, and social benefits to contemporary urban dwellers. To identify the current state of GI knowledge, a systematic quantitative literature review of peer-reviewed articles (n = 171) was undertaken using the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) method. Temporal publication trends, geographical and geological information of research efforts, as well as research focus areas were recorded and reported against each article. The findings of this review confirm the research area to be in a state of development in most parts of the world, with the vast majority of the research emerging from the United States, Australia, and the United Kingdom. Cooler climates produced the majority of research, which were found largely to be of a traditional research article format. The GI research area is firmly dominated by foci comprising planning and policy, environmental and ecological, and social content, although modest attempts have also appeared in health and wellbeing, economic, and quality/performance of green infrastructure areas. Knowledge gaps identified by this review as requiring attention for research growth were identified as: (i) the ambiguity of terminology and the limited broad understanding of GI, and (ii) the absence of research produced in the continents of Asia and South America, as well as in regions with warmer climates, which are arguably equally valuable research locations as cooler climate bands.

Climate change is a profoundly social and political challenge with many social justice concerns around every corner. A global issue, climate change threatens the well-being, livelihood, and survival of people in communities worldwide. Often, those who have contributed least to climate change are the most likely to suffer from its negative consequences and are often excluded from the policy discussions and decisions that affect their lives. This book pays particular attention to the social dimensions of climate change. It examines closely people’s lived experience, climate-related injustice and inequity, why some groups are more vulnerable than others, and what can be done about it—especially through greater community inclusion in policy change. A highlight of the book is its diversity of rich, community-based examples from throughout the Global South and North. Sacrificial flood zones in urban Argentina, forced relocation of United Houma tribal members in the United States, and gendered water insecurities in Bangladesh and Australia are just some of the in-depth cases included in the book. Throughout, the book asks social and political questions about climate change. Of key importance, it asks what can be done about the unequal consequences of climate change by questioning and transforming social institutions and arrangements—guided by values that prioritize the experience of affected groups and the inclusion of diverse voices and communities in the policy process.

Understanding long-term changes in human well-being is central to understanding the consequences of economic development. An extensive anthropometric literature purports to show that heights in the United States declined between the 1830s and the 1890s, which is when the U.S. economy modernized. Most anthropometric research contends that declining heights reflect the negative health consequences of industrialization and urbanization. This interpretation, however, relies on sources subject to selection bias. Our meta-analysis shows that the declining height during industrialization emerges primarily in selected samples. We also develop a parsimonious diagnostic test that reveals, but does not correct for, selection bias in height samples. When applied to four representative height samples, the diagnostic provides compelling evidence of selection.

<p>Climate change in the Arctic is noticeable and affecting the well-being of the population. The health and emotional state, food and water availability, livelihoods are on the threat. The towns are particularly sensitive to climate change. Their population and infrastructure density is exceptionally high, and temperature fluctuations, as well as extreme weather events, have an exceptionally strong impact on air and water quality, health and other components of human well-being. At the same time, urban communities in the Arctic, especially in industrial development zones, represent a little-studied area in this case.</p><p>The report presents the interdisciplinary study results concerning the climate change consequences for the population of Russian Arctic industrial developed areas. The study carried out in Murmansk Region which is a highly industrial and highly urbanized region that is completely included in the Arctic zone of the Russian Federation. Qualitative methods were used; in-depth (more than 50 questions) interviews were conducted with residents of several towns in the region. The study showed corresponds between the subjective perceptions of climate change by urban residents of the Murmansk Region with objective data on meteorological parameters changes. The surveyed urban residents feel changes in health and environmental management practices, and many respondents associate these changes with climate fluctuations. Such a phenomenon as the destruction of infrastructure (residential, public and industrial buildings, roads, energy infrastructure) due to climate change has not been identified. Concerns have been raised about the potential impact of climate warming on the ability to have a decent job due to reduced employment in some industries (such as energy).</p><p>The results obtained contribute to a better understanding of the social consequences of climate change in the Russian Arctic. This is important for adaptation actions development.</p><p> </p>

There is increasing evidence that extreme weather events such as frequent and intense cold spells and heat waves cause unprecedented deaths and diseases in both developed and developing countries. Thus, they require extensive and immediate research to limit the risks involved. Average temperatures in Europe in June–July 2019 were the hottest ever measured and attributed to climate change. The problem, however, of a thorough study of natural climate change is the lack of experimental data from the long past, where anthropogenic activity was then very limited. Today, this problem can be successfully resolved using, inter alia, biological indicators that have provided reliable environmental information for thousands of years in the past. The present study used high-resolution quantitative reconstruction data derived from biological records of Lake Silvaplana sediments covering the period 1181–1945. The purpose of this study was to determine whether a slight temperature change in the past could trigger current or future intense temperature change or changes. Modern analytical tools were used for this purpose, which eventually showed that temperature fluctuations were persistent. That is, they exhibit long memory with scaling behavior, which means that an increase (decrease) in temperature in the past was always followed by another increase (decrease) in the future with multiple amplitudes. Therefore, the increase in the frequency, intensity, and duration of extreme temperature events due to climate change will be more pronounced than expected. This will affect human well-being and mortality more than that estimated in today’s modeling scenarios. The scaling property detected here can be used for more accurate monthly to decadal forecasting of extreme temperature events. Thus, it is possible to develop improved early warning systems that will reduce the public health risk at local, national, and international levels.

The notion that digital-screen engagement decreases adolescent well-being has become a recurring feature in public, political, and scientific conversation. The current level of psychological evidence, however, is far removed from the certainty voiced by many commentators. There is little clear-cut evidence that screen time decreases adolescent well-being, and most psychological results are based on single-country, exploratory studies that rely on inaccurate but popular self-report measures of digital-screen engagement. In this study, which encompassed three nationally representative large-scale data sets from Ireland, the United States, and the United Kingdom ( N = 17,247 after data exclusions) and included time-use-diary measures of digital-screen engagement, we used both exploratory and confirmatory study designs to introduce methodological and analytical improvements to a growing psychological research area. We found little evidence for substantial negative associations between digital-screen engagement—measured throughout the day or particularly before bedtime—and adolescent well-being.

This is an advance summary of a forthcoming article in the Oxford Research Encyclopedia of Environmental Science. Please check back later for the full article. There are three important linkages to explore between climate change and health in terms of potential policy responses. The first of these linkages relates to the impacts on health resulting from climate change. In 2009, The Lancet described climate change as “the greatest global health threat of the 21st century,” referencing the direct and indirect effects it is having on public health. While a number of impacts are directly observable (i.e., an increased frequency and severity of many extreme weather events), others are more indirect, being mediated through environmental and social systems (i.e., the health complications associated with mass migration or violent conflict). Further, it is well understood that resilience and adaptive capacity play an important role in reducing these impacts—often leaving low-income communities worse off than most. The second important linkage between climate change and health relates to the co-benefits of mitigation and adaptation. Policy responses to climate change will inevitably come with both intended and unforseen externalities and “side-effects” (both positive and negative). Traditional public health tools, such as health impact assessment, can be valuable in identifying and understanding these co-benefits to better guide policy. Indeed, many of the mitigation solutions yield substantial benefits for public health: switching away from coal-fired power plants as an energy choice improves cardiovascular and respiratory health; designing cities which are cycle- and pedestrian-friendly increases rates of physical activity (helping to tackle obesity, diabetes, many cancers, and heart disease) while also reducing greenhouse gas emissions from vehicles. Finally, the health system itself has an important role in responding directly to climate change. This is frequently understood in terms of a health facility’s ability to withstand and respond to the impacts of climate change, and to the adaptive capacity of the health system itself. But there is also a role for the health system to play in reducing its own emissions. In countries like the United Kingdom and the United States, the formal health system is responsible for as much as 3–8% of national emissions, and has subsequently made commitments to reduce its environmental impact. A 2013 review of the UK National Health Service’s carbon footprint indicated that as much as 60% of this came from procurement, 17% from building energy, and 13% from health system–related transport. A number of the solutions available are often designed in a way that improves patient outcomes and satisfaction, while reducing the costs of healthcare. In low- and middle-income countries, the focus is placed on ensuring access to reliable electricity, a task well suited to decentralized micro-grids with sustainable power generation. Academic literature on the topic of health and climate change has expanded rapidly in recent years and includes the 2009 and 2015 Lancet Commissions on health and climate change, the 2010 series on the health co-benefits of mitigation, and the 2014 Intergovernmental Panel on Climate Change’s 5th Assessment Report.

This narrative review examined strategies for preparedness and response to mental health impacts of three forms of climate change from a services perspective: (1) acute and extreme weather events such as hurricanes, floods, and wildfires, (2) sub-acute or long-term events such as droughts and heatwaves; and (3) the prospect of long-term and permanent changes, including higher temperatures, rising sea levels, and an uninhabitable physical environment. Strategies for acute events included development and implementation of programs and practices for monitoring and treating mental health problems and strengthening individual and community resilience, training of community health workers to deliver services, and conducting inventories of available resources and assessments of at-risk populations. Additional strategies for sub-acute changes included advocacy for mitigation policies and programs and adaptation of guidelines and interventions to address the secondary impacts of sub-acute events, such as threats to livelihood, health and well-being, population displacement, environmental degradation, and civil conflict. Strategies for long-lasting changes included the implementation of evidence-based risk communication interventions that address the existing and potential threat of climate change, promoting the mental health benefits of environmental conservation, and promoting psychological growth and resilience.

Much of the United States’ critical infrastructure is either aging or requires significant repair, leaving U.S. communities and the economy vulnerable. Outdated and dilapidated infrastructure places coastal communities, in particular, at risk from the increasingly frequent and intense coastal storm events and rising sea levels. Therefore, investments in coastal infrastructure are urgently needed to ensure community safety and prosperity; however, these investments should not jeopardize the ecosystems and natural resources that underlie economic wealth and human well-being. Over the past 50 years, efforts have been made to integrate built infrastructure with natural landscape features, often termed “green” infrastructure, in order to sustain and restore valuable ecosystem functions and services. For example, significant advances have been made in implementing green infrastructure approaches for stormwater management, wastewater treatment, and drinking water conservation and delivery. However, the implementation of natural and nature-based infrastructure (NNBI) aimed at flood prevention and coastal erosion protection is lagging. There is an opportunity now, as the U.S. government reacts to the recent, unprecedented flooding and hurricane damage and considers greater infrastructure investments, to incorporate NNBI into coastal infrastructure projects. Doing so will increase resilience and provide critical services to local communities in a cost-effective manner and thereby help to sustain a growing economy.

Previous research concerning climate change in the United States clearly illustrates the necessity for observing how ecological systems are influenced by natural disasters (Staudinger et. al. 2013; Nelson et. al. 2013). Traditionally, ecology is concerned with the relationships between organisms (human and other living beings) and their environment (Tyler & Spoolman, 2013). Human understanding of how organisms are affected by, how they adapt to, and how they work to sustain their environment has become even more diverse in recent years (Staudinger et. al. 2013). This may be due to a number of environmental factors that have occurred in recent years. However, this paper seeks to examine the ecological effects of the wind factor. In particular, we address the ecological effects of hurricanes as it relates to (1) environmental outcomes and alterations among organisms in the United States, (2) the well-being and adaptation of human and organismic life (i.e. animals, plants, etc.) post Hurricane Katrina and Camille (3) and how hurricanes alter and transform health and restoration patterns in the U.S.


Significance For the first time in the eleven-year history of the survey, no economic risk makes the list of the top five most likely or biggest impact risks. In contrast, large-scale terrorist attacks make the top five most likely risks for the first time and weapons of mass destruction are cited as the highest impact risk. All five environment-related risks are ranked among the top ten highest impact risks for the first time -- four in the top five: extreme weather events; water crises; major natural disasters; and failure of climate change mitigation and adaptation. The survey cites strengthening global cooperation systems as a top five challenge, and says these environmental risks will be exacerbated if cooperation diminishes. Impacts Nearly a third of respondents think that increasing polarisation will be an underlying trend over the next ten years. More must be done to include the people left behind by technological change -- more than 4 billion lack internet access. The United States may withdraw from the Paris climate change agreement, and a number of free trade deals are at risk.
