Climate Change, Cattle, And The Challenge Of Sustainability In A Telecoupled System In Africa, Tara S. Easter, Alexander K. Killion, Neil H. Carter
Climate Change, Cattle, And The Challenge Of Sustainability In A Telecoupled System In Africa, Tara S. Easter, Alexander K. Killion, Neil H. Carter
Neil H. Carter
Information, energy, and materials are flowing over greater distances than in the past, changing the structure and feedbacks within and across coupled human and natural systems worldwide. The telecoupling framework was recently developed to understand the feedbacks and multidirectional flows characterizing social and environmental interactions between distant systems. We extend the application of the telecoupling framework to illustrate how flows in beef affect and are affected by social-ecological processes occurring between distant systems in Africa, and how those dynamics will likely change over the next few decades because of climate-induced shifts in a major bovine disease, trypanosomosis. The disease is …

Changes In Severe Thunderstorm Environment Frequency During The 21st Century Caused By Anthropogenically Enhanced Global Radiative Forcing, Robert J. Trapp, Noah S. Diffenbaugh, Harold E. Brooks, Michael E. Baldwin, Eric D. Robinson, Jeremy S. Pal
Jeremy Pal
Severe thunderstorms comprise an extreme class of deep convective clouds and produce high-impact weather such as destructive surface winds, hail, and tornadoes. This study addresses the question of how severe thunderstorm frequency in the United States might change because of enhanced global radiative forcing associated with elevated greenhouse gas concentrations. We use global climate models and a high-resolution regional climate model to examine the larger-scale (or “environmental”) meteorological conditions that foster severe thunderstorm formation. Across this model suite, we find a net increase during the late 21st century in the number of days in which these severe thunderstorm environmental conditions …
The Costs Of Photorespiration To Food Production Now And In The Future, Berkley J. Walker, Andy Vanloocke, Carl J. Bernacchi, Donald R. Ort
The Costs Of Photorespiration To Food Production Now And In The Future, Berkley J. Walker, Andy Vanloocke, Carl J. Bernacchi, Donald R. Ort
Andy VanLoocke
Photorespiration is essential for C3 plants but operates at the massive expense of fixed carbon dioxide and energy. Photorespiration is initiated when the initial enzyme of photosynthesis, ribulose-1,5-bisphosphate carboxylase/ oxygenase (Rubisco), reacts with oxygen instead of carbon dioxide and produces a toxic compound that is then recycled by photorespiration. Photorespiration can be modeled at the canopy and regional scales to determine its cost under current and future atmospheres. A regional-scale model reveals that photorespiration currently decreases US soybean and wheat yields by 36% and 20%, respectively, and a 5% decrease in the losses due to photorespiration would be worth approximately …

Mapping Temperate Vegetation Climate Adaptation Variability Using Normalized Land Surface Phenology, Liang Liang, Mark D. Schwartz, Xiaoyang Zhang
Xiaoyang Zhang
Climate influences geographic differences of vegetation phenology through both contemporary and historical variability. The latter effect is embodied in vegetation heterogeneity underlain by spatially varied genotype and species compositions tied to climatic adaptation. Such long-term climatic effects are difficult to map and therefore often neglected in evaluating spatially explicit phenological responses to climate change. In this study we demonstrate a way to indirectly infer the portion of land surface phenology variation that is potentially contributed by underlying genotypic differences across space. The method undertaken normalized remotely sensed vegetation start-of-season (or greenup onset) with a cloned plants-based phenological model. As the …

The Impacts Of Climate Change Mitigation Strategies On Animal Welfare, Sara Shields, Geoffrey Orme-Evans
The Impacts Of Climate Change Mitigation Strategies On Animal Welfare, Sara Shields, Geoffrey Orme-Evans
Sara Shields, PhD
The objective of this review is to point out that the global dialog on reducing greenhouse gas emissions in animal agriculture has, thus far, not adequately considered animal welfare in proposed climate change mitigation strategies. Many suggested approaches for reducing emissions, most of which could generally be described as calls for the intensification of production, can have substantial effects on the animals. Given the growing world-wide awareness and concern for animal welfare, many of these approaches are not socially sustainable. This review identifies the main emission abatement strategies in the climate change literature that would negatively affect animal welfare and …

Flowering Phenology Change And Climate Warming In Southwestern Ohio, Ryan Mcewan, Robert J. Brecha, Donald R. Geiger, Grace P. John
Robert J. Brecha
Global surface temperature has increased markedly over the last 100 years. This increase has a variety of implications for human societies, and for ecological systems. One of the most obvious ways ecosystems are affected by global climate change is through alteration of organisms’ developmental timing (phenology). We used annual botanical surveys that documented the first flowering for an array of species from 1976 to 2003 to examine the potential implications of climate change for plant development. The overall trend for these species was a progressively earlier flowering time. The two earliest flowering taxa (Galanthus and Crocus) also exhibited the strongest …

Climate change is commonly cast as a significant governance challenge demanding national and international actions. Subsequently, political science research tends to focus on the policy and politics of nation-states, their domestic institutions, and/or their interplay in international venues. However, thousands of industrial facilities and hundreds of subnational US governments are active in American climate risk governance. Therefore, we argue that more research should attend to climate governance’s subnational policy and politics, their promise, and their performance. In the vacuum of national policies to mitigate and adapt to climate-change, subnational arrangements offer an ideal opportunity to study not only the spontaneity …

Diatom Community Response To Climate Variability Over The Past 37,000 Years In The Sub-Tropics Of The Southern Hemisphere, Sarah Hembrow, Kathryn Taffs, Pia Atahan, Jeffrey Parr, Atun Zawadzki, Henk Heijnis
Jeffrey Parr
Climate change is impacting global surface water resources, increasing the need for a deeper understanding of the interaction between climate and biological diversity. This is particularly the case in the Southern Hemisphere sub-tropics, where little information exists on the aquatic biota response to climate variations. Palaeolimnological techniques, in particular the use of diatoms, are well established and can significantly contribute to the understanding of climatic variability and the impacts that change in climate have on aquatic ecosystems. A sediment core from Lake McKenzie, Fraser Island (Australia), was used to investigate interactions between climate influences and aquatic ecosystems. This study utilises …

Climate change, understood as a statistically significant variation in the mean state of the climate or its variability, is the greatest environmental challenge of this generation (Intergovernmental Panel on Climate Change, 2001). Marshfield is already being affected by changes in the climate that will have a profound effect on the town’s economy, public health, coastal resources, natural features, water systems, and public and private infrastructure. Adaptation strategies have been widely recognized as playing an important role in improving a community’s ability to respond to climate stressors by resisting damage and recovering quickly. Based on review of climate projections for the …

Lagoons are highly productive coastal features that provide a range of natural services that society values. Their setting within the coastal landscape leaves them especially vulnerable to profound physical, ecological, and associated societal disturbance from global climate change. Expected shifts in physical and ecological characteristics range from changes in flushing regime, freshwater inputs, and water chemistry to complete inundation and loss and the concomitant loss of natural and human communities. Therefore, managing coastal lagoons in the context of global climate change is critical. Although management approaches will vary depending on local conditions and cultural norms, all management scenarios will need …

Appropriate Climate Change Solutions: Towards Sustainable Bioenergy Agro-Production In Africa For Energy Equality And Poverty Alleviation, Ian Duvenage, Ros Taplin, Lindsay C. Stringer
Roslyn Taplin
Limited energy access within developing nations particularly in Africa is a primary reason for poverty. Biofuel production has been advocated by many experts as a solution to meeting the energy needs of African countries while reducing greenhouse gas (GHG) emissions. Others argue that biofuel production will compete with land needed for food production. However it appears many African countries have available land beyond food needs, hence biofuel production may be an option for poor farmers to gain skills, create economic diversification and provide affordable energy without environmental degradation. This paper reviews the situation in Africa with regard to biofuels and …
Local Governments’ Risk-Based Approach To Climate Change Adaptation: A Missed Opportunity For Resilience In New South Wales, Nadine E. White
Local Governments’ Risk-Based Approach To Climate Change Adaptation: A Missed Opportunity For Resilience In New South Wales, Nadine E. White
Nadine E White
Parts of New South Wales (NSW) have experienced warming of 1.5 to 2.0 degrees Celsius in the period 1960 to 2009, indicating that the impacts of climate change are already being felt. Immediate, effective adaptation to potential impacts is crucial in reducing vulnerability to climate change. All three levels of government in Australia have a role in adaptation planning however it is local government that is at the ‘coal face’ of the outcomes of imminent climatic changes. This empirical research seeks to discover whether the existing institutional and cultural environment of local governments in NSW facilitates or impedes effective adaptation. …
Designing For Future Buildings: Adaptive Resuse As A Strategy For Carbon Neutral Cities, Sheila Conejos, Craig Langston, Jim Smith
Designing For Future Buildings: Adaptive Resuse As A Strategy For Carbon Neutral Cities, Sheila Conejos, Craig Langston, Jim Smith
Craig Langston
Adapting existing buildings is a viable alternative to demolition and replacement in order to mitigate climate change and global warming. Australian cities with inherent cultural heritage fabric, like Melbourne and Sydney, are actively promoting building adaptive reuse as a strategy that supports their programme for developing carbon-neutral cities. Thus, designing for future buildings with embedded adaptive reuse potential is a useful criterion for sustainability. Building adaptive reuse entails less energy and waste, protects the buildings’ heritage values- its socio-cultural and historic meanings; while giving them a new lease of life. This paper looks into urban conservation-- an interdisciplinary field that …

Developing The Next Generation Of Women And Minority Scientists For The Nuclear Energy Industry, Darrell Burrell, Andrea Todd, Aikyna Finch, Maurice Dawson
Maurice Dawson
The largest source of carbon dioxide emissions globally is the combustion of fossil fuels (coal, oil and natural gas) in power plants, automobiles, industrial facilities and other sources. Generating electricity is the single largest source of carbon dioxide emissions, representing 41% of all emissions. Since 2007 the United States has been more actively considering nuclear power as an option for developing energy. Three decades after the Three Mile Island accident seemed to doom the nuclear power industry, the idea of a nuclear renaissance has been gaining public acceptance as a way to generate energy without greenhouse gas emissions and meet …

Global Effects Of Climate Change On Wildfire: Causal Relationships Of Fire, The Natural Environment And Human Activities, Lindon N. Pronto
Lindon N Pronto
Climate change and human activity is significantly impacting the frequency and severity of wildfires across the globe. Although climate change and human population are the overarching factors affecting wildfires in the current dialogue, the issues are more complex and often not fully understood. These issues range from global temperature increases and severe drought cycles to the relatively new phenomenon of the wildland urban interface (WUI). This is the area where structures are integrated with or immediately surrounded by areas of moderate to high fire risk and are directly linked to fuel types and topographic features. Because climate change is such …
