    Description: The U.N. Framework Convention on Climate Change’s (UNFCCC’s) Paris Agreement—which aims to limit climate change and increase global resilience to its effects—was a breakthrough in climate diplomacy, committing its Parties to develop and update national climate plans. Yet the Parties to the Agreement have largely overlooked the effect of climate change on ocean-based communities, economies, and ecosystems—as well as the role that the ocean can play in mitigating and adapting to climate change. Because the ocean is an integral part of the climate system, stronger inclusion of ocean issues is critical to achieving the Agreement’s goals. Here we discuss four ocean-climate linkages that suggest specific responses by Parties to the Agreement connected to 1) accelerating climate ambition, including via sustainable ocean-based mitigation strategies; 2) focusing on CO2 emissions to address ocean acidification; 3) better understanding ocean-based mitigation; and 4) pursuing ocean-based adaptation. These linkages offer a more complete perspective on the reasons strong climate action is necessary and inform a systematic approach for addressing ocean issues under the Agreement to strengthen climate mitigation and adaptation.

    Description: Over the past five years, no other issue has received more attention in the marine science community than ocean acidification. Ocean acidification is a multi-disciplinary research area that encompasses topics such as chemistry, paleontology, biology, ecology, biogeochemistry, modeling, social sciences and economics. With this complexity and the continued development of our understanding in mind, the U.S. Ocean Carbon and Biogeochemistry (OCB; www.us-ocb.org) program, with support from the UK Ocean Acidification Research Programme (UKOA; http://www.oceanacidification.org.uk/), has updated and expanded a list of frequently asked questions (FAQs) that were developed in 2010 by OCB, the European Project on Ocean Acidification (EPOCA), and UKOA. Equipped with the most up-to-date information, the global ocean acidification research community has drafted concise, understandable summaries of the current knowledge. The responses were carefully vetted during an open peer-review and revision process to ensure readability without any loss of scientific accuracy. This effort was international in scale, with 63 scientists from 47 institutions and 12 countries contributing to the process.

    Description: Many of the declarations and outcome documents from prior United Nations international meetings address ocean issues such as fishing, pollution, and climate change, but they do not address ocean acidification. This progressive alteration of seawater chemistry caused by uptake of atmospheric carbon dioxide (CO2) is an emerging issue of concern that has potential consequences for marine ecosystems and the humans that depend on them. Addressing ocean acidification will require mitigation of global CO2 emissions at the international level accompanied by regional marine resource use adaptations that reduce the integrated pressure on marine ecosystems while the global community works towards implementing permanent CO2 emissions reductions. Addressing ocean acidification head-on is necessary because it poses a direct challenge to sustainable development targets such as the Millennium Development Goals, and it cannot be addressed adequately with accords or geoengineering plans that do not specifically decrease atmospheric carbon dioxide levels. Here, we will briefly review the current state of ocean acidification knowledge and identify several mitigation and adaptation strategies that should be considered along with reductions in CO2 emissions to reduce the near-term impacts of ocean acidification. Our goal is to present potential options while identifying some of their inherent weaknesses to inform decisionmaking discussions, rather than to recommend adoption of specific policies. While the reduction of CO2 emissions should be the number one goal of the international community, it is unlikely that the widespread changes and infrastructure redevelopment necessary to accomplish this will be achieved soon, before ocean acidification’s short-term impacts become significant. Therefore, a multi-faceted approach must be employed to address this growing problem.

    Description: Global change is occurring now, often with consequences far beyond those anticipated. Although there is a wide range of assessment approaches available to address specific aspects of global change, there is currently no framework to identify what governance responses have worked and where, what has facilitated change, and what preventative options are possible. To respond to this need, we present an integrated assessment framework that builds on knowledge learned from past experience of responses to global change, to enable decision makers, researchers, managers and local stakeholders to: (1) make decisions efficiently; (2) triage and improve their responses; and (3) evaluate where to most effectively allocate resources to reduce vulnerability and enhance resilience of coastal peoples. This integrated assessment framework, IMBER-ADApT is intended to enable and enhance decision making through the development a typology of case studies providing lessons on how the natural, social and governance systems respond to the challenges of global change. The typology is developed from a database of case studies detailing the systems affected by change, responses to change and, critically, an appraisal of these responses, generating knowledge-based solutions that can be applied to other comparable situations. Fisheries, which suffer from multiple pressures, are the current focus of the proposed framework, but it could be applied to a wide range of global change issues. IMBER-ADApT has the potential to contribute to timely, cost-effective policy and governing decision making and responses. It offers cross-scale learning to help ameliorate, and eventually prevent, loss of livelihoods, food sources and habitat.

    Projected impacts of future climate change, ocean acidification, and management on the US Atlantic sea scallop (Placopecten magellanicus) fishery (2018)

    Description: Ocean acidification has the potential to significantly impact both aquaculture and wild-caught mollusk fisheries around the world. In this work, we build upon a previously published integrated assessment model of the US Atlantic Sea Scallop (Placopecten magellanicus) fishery to determine the possible future of the fishery under a suite of climate, economic, biological, and management scenarios. We developed a 4x4x4x4 hypercube scenario framework that resulted in 256 possible combinations of future scenarios. The study highlights the potential impacts of ocean acidification and management for a subset of future climate scenarios, with a high CO2 emissions case (RCP8.5) and lower CO2 emissions and climate mitigation case (RCP4.5). Under RCP4.5 and the highest impact and management scenario, ocean acidification has the potential to reduce sea scallop biomass by approximately 13% by the end of century; however, the lesser impact scenarios cause very little change. Under RCP8.5, sea scallop biomass may decline by more than 50% by the end of century, leading to subsequent declines in industry landings and revenue. Management-set catch limits improve the outcomes of the fishery under both climate scenarios, and the addition of a 10% area closure increases future biomass by more than 25% under the highest ocean acidification impacts. However, increased management still does not stop the projected long-term decline of the fishery under ocean acidification scenarios. Given our incomplete understanding of acidification impacts on P. magellanicus, these declines, along with the high value of the industry, suggest population-level effects of acidification should be a clear research priority. Projections described in this manuscript illustrate both the potential impacts of ocean acidification under a business-as-usual and a moderately strong climate-policy scenario. We also illustrate the importance of fisheries management targets in improving the long-term outcome of the P. magellanicus fishery under potential global change.

    Anticipating ocean acidification's economic consequences for commercial fisheries (2009)

    Description: Ocean acidification, a consequence of rising anthropogenic CO2 emissions, is poised to change marine ecosystems profoundly by increasing dissolved CO2 and decreasing ocean pH, carbonate concentration, and calcium carbonate mineral saturation state worldwide. These conditions hinder growth of calcium carbonate shells and skeletons by many marine plants and animals. The first direct impact on humans may be through declining harvests and fishery revenues from shellfish, their predators, and coral reef habitats. In a case study of U.S. commercial fishery revenues, we begin to constrain the economic effects of ocean acidification over the next 50 years using atmospheric CO2 trajectories and laboratory studies of its effects, focusing especially on mollusks. In 2007, the $3.8 billion U.S. annual domestic ex-vessel commercial harvest ultimately contributed $34 billion to the U.S. gross national product. Mollusks contributed 19%, or $748 million, of the ex-vessel revenues that year. Substantial revenue declines, job losses, and indirect economic costs may occur if ocean acidification broadly damages marine habitats, alters marine resource availability, and disrupts other ecosystem services. We review the implications for marine resource management and propose possible adaptation strategies designed to support fisheries and marine-resource-dependent communities, many of which already possess little economic resilience.

    Ocean acidification’s potential to alter global marine ecosystem services (2010)

    Description: Ocean acidification lowers the oceanic saturation states of carbonate minerals and decreases the calcification rates of some marine organisms that provide a range of ecosystem services such as wild fishery and aquaculture harvests, coastal protection, tourism, cultural identity, and ecosystem support. Damage to marine ecosystem services by ocean acidification is likely to disproportionately affect developing nations and coastal regions, which often rely more heavily on a variety of marine-related economic and cultural activities. Losses of calcifying organisms or changes in marine food webs could significantly alter global marine harvests, which provided 110 million metric tons of food for humans and were valued at US$160 billion in 2006. Some of the countries most dependent on seafood for dietary protein include developing island nations with few agricultural alternatives. Aquaculture, especially of mollusks, may meet some of the future protein demand of economically developing, growing populations, but ocean acidification may complicate aquaculture of some species. By 2050, both population increases and changes in carbonate mineral saturation state will be greatest in low-latitude regions, multiplying the stresses on tropical marine ecosystems and societies. Identifying costeffective adaptive strategies to mitigate the costs associated with ocean acidification requires development of transferable management strategies that can be tailored to meet the specific needs of regional human and marine communities.

    Description: The uptake of anthropogenic CO2 by the global ocean induces fundamental changes in seawater chemistry that could have dramatic impacts on biological ecosystems in the upper ocean. Estimates based on the Intergovernmental Panel on Climate Change (IPCC) business-as-usual emission scenarios suggest that atmospheric CO2 levels could approach 800 ppm near the end of the century. Corresponding biogeochemical models for the ocean indicate that surface water pH will drop from a pre-industrial value of about 8.2 to about 7.8 in the IPCC A2 scenario by the end of this century, increasing the ocean’s acidity by about 150% relative to the beginning of the industrial era. In contemporary ocean water, elevated CO2 will also cause substantial reductions in surface water carbonate ion concentrations, in terms of either absolute changes or fractional changes relative to pre-industrial levels. For most open-ocean surface waters, aragonite undersaturation occurs when carbonate ion concentrations drop below approximately 66 μmol kg-1. The model projections indicate that aragonite undersaturation will start to occur by about 2020 in the Arctic Ocean and 2050 in the Southern Ocean. By 2050, all of the Arctic will be undersaturated with respect to aragonite, and by 2095, all of the Southern Ocean and parts of the North Pacific will be undersaturated. For calcite, undersaturation occurs when carbonate ion concentration drops below 42 μmol kg-1. By 2095, most of the Arctic and some parts of the Bering and Chukchi seas will be undersaturated with respect to calcite. However, in most of the other ocean basins, the surface waters will still be saturated with respect to calcite, but at a level greatly reduced from the present.

    Description: New England coastal and adjacent Nova Scotia shelf waters have a reduced buffering capacity because of significant freshwater input, making the region’s waters potentially more vulnerable to coastal acidification. Nutrient loading and heavy precipitation events further acidify the region’s poorly buffered coastal waters. Despite the apparent vulnerability of these waters, and fisheries’ and mariculture’s significant dependence on calcifying species, the community lacks the ability to confidently predict how the region’s ecosystems will respond to continued ocean and coastal acidification. Here, we discuss ocean and coastal acidification processes specific to New England coastal and Nova Scotia shelf waters and review current understanding of the biological consequences most relevant to the region. We also identify key research and monitoring needs to be addressed and highlight existing capacities that should be leveraged to advance a regional understanding of ocean and coastal acidification.

    An integrated assessment model for helping the United States sea scallop (Placopecten magellanicus) fishery plan ahead for ocean acidification and warming (2015)
    Public Library of Science
    Details

    Description: © The Author(s), 2015. This is an open access article, free of all copyright. The definitive version was published in PLoS One 10 (2015): e0124145, doi:10.1371/journal.pone.0124145.
    Description: Ocean acidification, the progressive change in ocean chemistry caused by uptake of atmospheric CO2, is likely to affect some marine resources negatively, including shellfish. The Atlantic sea scallop (Placopecten magellanicus) supports one of the most economically important single-species commercial fisheries in the United States. Careful management appears to be the most powerful short-term factor affecting scallop populations, but in the coming decades scallops will be increasingly influenced by global environmental changes such as ocean warming and ocean acidification. In this paper, we describe an integrated assessment model (IAM) that numerically simulates oceanographic, population dynamic, and socioeconomic relationships for the U.S. commercial sea scallop fishery. Our primary goal is to enrich resource management deliberations by offering both short- and long-term insight into the system and generating detailed policy-relevant information about the relative effects of ocean acidification, temperature rise, fishing pressure, and socioeconomic factors on the fishery using a simplified model system. Starting with relationships and data used now for sea scallop fishery management, the model adds socioeconomic decision making based on static economic theory and includes ocean biogeochemical change resulting from CO2 emissions. The model skillfully reproduces scallop population dynamics, market dynamics, and seawater carbonate chemistry since 2000. It indicates sea scallop harvests could decline substantially by 2050 under RCP 8.5 CO2 emissions and current harvest rules, assuming that ocean acidification affects P. magellanicus by decreasing recruitment and slowing growth, and that ocean warming increases growth. Future work will explore different economic and management scenarios and test how potential impacts of ocean acidification on other scallop biological parameters may influence the social-ecological system. Future empirical work on the effect of ocean acidification on sea scallops is also needed.
