Enhanced Acidification Of Global Coral Reefs Driven By Regional Biogeochemical Feedbacks, Tyler Cyronak, Kai G. Schulz, Isaac R. Santos, Bradley D. Eyre
Enhanced Acidification Of Global Coral Reefs Driven By Regional Biogeochemical Feedbacks, Tyler Cyronak, Kai G. Schulz, Isaac R. Santos, Bradley D. Eyre
Tyler Cyronak
Physical uptake of anthropogenic CO2 is the dominant driver of ocean acidification (OA) in the open ocean. Due to expected decreases in calcification and increased dissolution of CaCO3 framework, coral reefs are thought to be highly susceptible to OA. However, biogeochemical processes can influence the pCO2 and pH of coastal ecosystems on diel and seasonal time scales, potentially modifying the long‐term effects of increasing atmospheric CO2. By compiling data from the literature and removing the effects of short‐term variability, we show that the average pCO2 of coral reefs throughout the globe has increased ~3.5‐fold …
Marine Invertebrates: Communities At Risk, Jennifer A. Mather
Marine Invertebrates: Communities At Risk, Jennifer A. Mather
Jennifer Mather, PhD
Our definition of the word ‘animal’ centers on vertebrates, yet 99% of the animals on the planet are invertebrates, about which we know little. In addition, although the Census of Marine Life (COML.org) has recently conducted an extensive audit of marine ecosystems, we still do not understand much about the animals of the seas. Surveys of the best-known ecosystems, in which invertebrate populations often play a key role, show that the invertebrate populations are affected by human impact. Coral animals are the foundation of coral reef systems, which are estimated to contain 30% of the species in the ocean. Physical …

Teaching Climate Change Concepts And The Nature Of Science: A Library Activity To Identify Sources Of Climate Change Misconceptions, Charity Flener Lovitt, Kristen S. Shuyler
Teaching Climate Change Concepts And The Nature Of Science: A Library Activity To Identify Sources Of Climate Change Misconceptions, Charity Flener Lovitt, Kristen S. Shuyler
Kristen S. Shuyler
A library activity was developed in which students found information about climate science misconceptions from popular and scientific literatures. As part of the activity, students developed a rubric to evaluate the credibility and type of literature sources they found. The activity prepared students to produce an annotated bibliography of articles, which they then used to create a training document about a climate science misconception for staff at a local science center. Evaluation of annotated bibliographies showed that students were able to distinguish between popular and scholarly literature but struggled to identify primary and secondary sources within the scholarly literature. In …

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
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 …

Can The Financialised Atmosphere Be Effectively Regulated And Accounted For?, Patty Mcnicholas, Carolyn Windsor
Carolyn Windsor
Purpose – This paper aims to carry out a critical analysis of the proposed Australian emissions trading scheme (ETS) as a complex market solution to reduce greenhouse gases (GHGs). Specifically it seeks to examine the financial regulatory infrastructure that will more than likely oversee the Australian ETS, the same regulatory infrastructure which failed to prevent the global financial crisis.Design/methodology/approach – A critical examination of the financialisation of the atmosphere that follows the growth of the financialisation of capitalism when economic activity shifted from production and service sectors to finance. Financialisation of capitalism is supported by capitalist regulation influenced by neo-liberal …
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 …
A Model For Mountain Pine Beetle Outbreaks In An Age-Structured Forest: Predicting Severity And Outbreak Recovery Cycle Period, Jacob P. Duncan
A Model For Mountain Pine Beetle Outbreaks In An Age-Structured Forest: Predicting Severity And Outbreak Recovery Cycle Period, Jacob P. Duncan
Jacob P Duncan
The mountain pine beetle (MPB, Dendroctonus ponderosae), a tree-killing bark beetle, has historically been part of the normal disturbance regime in lodgepole pine (Pinus contorta) forests. In recent years,warm winters and summers have allowed MPB populations to achieve synchronous emergence and successful attacks, resulting in widespread population outbreaks and resultant tree mortality across western North America. We develop an age-structured forest demographic model that incorporates temperature-dependent MPB infestations. Stability of fixed points is analyzed as a function of (thermally controlled) MPB population growth rates and indicates the existence of periodic outbreaks that intensify as growth rates increase. We devise analytical …

Recent evidence suggests that climate change is occurring at an accelerated rate as a result of human-induced greenhouse gas emissions and associated pollutants. Based on a recently completed study, the authors describe the changes Maine’s climate is likely to undergo over the next century. They suggest that while reduction of greenhouse gases is crucial, Maine needs to be prepared to adapt to the impact that our already changing climate will have on various ecosystems and economic sectors within the state

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 …

Jonathan G. Cooper
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 …
