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

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 …

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 …

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

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 …

Maine’S Climate Yesterday, Today, And Tomorrow, George L. Jacobson, Ivan J. Fernandez, Paul A. Mayewski, Catherine V. Schmitt

Ivan J. Fernandez

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 …

Coastal Lagoons And Climate Change: Ecological And Social Ramifications In The U.S. Atlantic And Gulf Coast Ecosystems, Abigail Anthony, Joshua Atwood, Peter August, Carrie Byron, Stanley Cobb, Cheryl Foster, Crystal Fry, Arthur Gold, Kifle Hagos, Leanna Heffner, D. Kellogg, Kimberly Lellis-Dibble, James Opaluch, Candace Oviatt, Anna Pfeiffer-Herbert, Nicole Rohr, Leslie Smith, Tiffany Smythe, Judith Swift, Nathan Vinhateiro

Peter August

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 …

Federal Energy Efficiency And Conservation Laws, John Dernbach, Marianne Tyrrell

John C. Dernbach

This paper provides an overview of U.S. law and policy concerning energy efficiency and conservation. The United States appears torn between two narratives - one expressing the abundant demonstrated opportunities provided by energy savings and the other based on a fear of deprivation from using less energy. Rather than choosing between the two, U.S. law and policy splits the difference - embracing efficiency and conservation more or less halfheartedly. Energy efficiency and conservation policy thus has a Groundhog Day aspect, in which the same or similar arguments are made year after year, decade after decade, and often (it appears) to …

The Essential And Growing Role Of Legal Education In Achieving Sustainability, John Dernbach

John C. Dernbach

This article suggests that law schools need to play a leading role in the national and global effort to achieve sustainability, including the effort to address climate change. The article first describes the various drivers for sustainability in law schools. Clients are increasingly demanding that their lawyers 'walk the talk,' as many businesses and corporations already are. The universities that provide an institutional home for most law schools are also adopting sustainability policies and practices that influence their law schools. Within the legal profession, the American Bar Association, as well as many state and local bar associations, have adopted a …

The "Cash For Clunkers" Program: A Sustainability Evaluation, Marianne Tyrrell, John Dernbach

John C. Dernbach

This article describes and evaluates the effectiveness of the Consumer Assistance to Recycle and Save Act of 2009, also known as the “Cash for Clunkers” legislation. Under this law, Congress authorized persons trading in older and less fuel-efficient motor vehicles for newer and more fuel-efficient vehicles to receive a voucher worth up to $4,500 toward the purchase of the new vehicle. The article reviews various studies assessing the effectiveness of this legislation based on economic, social, and environmental criteria. Because these criteria are consistent with the goals of sustainable development, the legislation provides important lessons for future efforts to achieve …

Energy Efficiency And Conservation: New Legal Tools And Opportunities, John Dernbach, Robert Mckinstry, Darin Lowder

John C. Dernbach

Many new and ambitious energy efficiency and conservation laws are being enacted at all levels of government—and with greater financial incentives than provided previously. These innovations are intended to overcome or minimize market barriers such as principal-agent problems, information and transaction costs, high internal discount rates, and up-front capital needs that discourage cost-saving investments. Innovations such as public-private partnerships also require significant legal input and creativity for the client to reap the often remarkably large energy and cost savings. This article reviews a range of these tools, especially financial legal mechanisms, that could help significantly reduce U.S. energy consumption.

Recent Advances In The Climate Change Biology Literature: Describing The Whole Elephant, A. Townsend Peterson, Shaily Menon, Xingong Li

Shaily Menon

Climate change biology is seeing a wave of new contributions, which are reviewed herein. Contributions treat shifts in phenology and distribution, and both document past and forecast future effects. However, many of the current wave of contributions are observational and correlational, and few are experimental in nature, and too often a conceptual framework in which to contextualize the results is lacking. An additional gap is the lack of effective cross-linking among areas of research, for example, connection of sea-level rise and climate change implications for distributions of species, or evolutionary adaptation studies with distributional shift studies. Although numerous important contributions …

Making The States Full Partners In A National Climate Change Effort: A Necessary Element For Sustainable Economic Development, John Dernbach, Robert Mckinstry, Thomas Peterson

John C. Dernbach

This article explains why states and localities need to be full partners in a national climate change effort based on federal legislation or the existing Clean Air Act. A large share of reductions with the lowest cost and the greatest co-benefits (e.g., job creation, technology development, reduction of other pollutants) are in areas that a federal cap-and-trade program or other purely federal measures will not easily reach. These are also areas where the states have traditionally exercised their powers—including land use, building construction, transportation, and recycling. The economic recovery and expansion will require direct state and local management of climate …

An Agenda For Sustainable Communities, John Dernbach

John C. Dernbach

This article summarizes progress toward sustainable communities in the United States since the United Nations Conference on Environment and Development (or Earth Summit) in 1992. It shows the significant initiative that many communities have undertaken and identifies existing state and federal laws as impediments to achieving sustainability. This article also makes recommendations for further progress based on what we have already learned about how to achieve sustainable communities. They include not only more and strengthened sustainable community efforts, and broad state and federal legal support, but also deep engagement of all affected citizens. This article is based primarily on three …

Navigating The U.S. Transition To Sustainability: Matching National Governance Challenges With Appropriate Legal Tools, John Dernbach

John C. Dernbach

Sustainable development would require the United States to maintain and improve human prosperity while at the same time greatly reducing its consumption of energy, materials, water, and land. The scope of the challenge includes, but is not limited to, climate change. This Article suggests the elements of a legal structure for achieving sustainability.

Because achieving sustainable development is a significant learning experience, the United States will need to employ a form of governance—reflexive governance—that requires constant learning and supportive citizens and stakeholders who are also working to ensure sustainability in their own activities. The two basic problems reflexive governance must …

Achieving Early And Substantial Greenhouse Gas Reductions Under A Post-Kyoto Agreement, John Dernbach

John C. Dernbach

This article explains why policy makers should seriously consider substantial early reductions in greenhouse gas emissions as a part of any post-Kyoto framework, and sets out suggested elements of a framework for early action in a post-Kyoto agreement. Substantial early reductions are needed because of the growing urgency of the climate change science, the precautionary approach identified in the Framework Convention on Climate Change as a decision-making principle, the fact that cost-effective measures are now available, and the significant non-climate benefits (security, economic, social, and environmental) that can be achieved by implementing them. As a practical matter, too, long-term greenhouse …

Stabilizing And Then Reducing U.S. Energy Consumption: Legal And Policy Tools For Efficiency And Conservation, John Dernbach

John C. Dernbach

Rising global demand for energy, high energy prices, climate change, and the threat of terrorism all point to the need for greater energy efficiency and conservation in the United States. While technological innovation is plainly needed, our laws and institutional arrangements must also play an important role. The United States has scores of legal and policy tools from which to choose to improve energy efficiency and curb energy consumption. This article evaluates a handful of these tools: transit-oriented development; fuel taxation; real-time pricing for electricity use; public benefit funds; improved efficiency in existing residential and commercial buildings; and expanded use …
