Abstract

The goal of this NOAA Fisheries Climate Science Strategy (Strategy) is to increase the production, delivery, and use of climate-related information required to fulfill NOAA Fisheries mandates. Although the information needed to understand, prepare for, and respond to climate change impacts on LMRs is diverse, this Strategy identifies seven common objectives to efficiently and effectively meet these information requirements. The seven objectives are:

Abstract

In late July 2013, the Island Institute hosted a workshop with approximately 110 fishermen, scientists, managers, policy makers, non-governmental organizations, and others in Portland, Maine. The goal—to discuss the latest science of climate change and the ocean, as well as changes fishermen are seeing at sea. The workshop focused on improving our collective understanding of how climate change is impacting New England fisheries and fishermen.

Abstract

This paper is intended as a reference document—a “science summary”— for the Ecosystems, Species, and Habitats Topic Advisory Group (TAG), which is one of four topic groups working with state agencies to prepare a statewide Integrated Climate Change Response Strategy. The climate change response strategy was initiated by the state legislature (SB 5560) to help the state adapt to climate change.

Abstract

Fish population variability and fisheries activities are closely linked to weather and climate dynamics. While weather at sea directly affects fishing, environmental variability determines the distribution, migration, and abundance of fish. Fishery science grew up during the last century by integrating knowledge from oceanography, fish biology, marine ecology, and fish population dynamics, largely focused on the great Northern Hemisphere fisheries. During this period, understanding and explaining interannual fish recruitment variability became a major focus for fisheries oceanographers.

Abstract

Evidence of the impacts of anthropogenic climate change on marine ecosystems is accumulating, but must be evaluated in the context of the “normal” climate cycles and variability which have caused fluctuations in fisheries throughout human history. The impacts on fisheries are due to a variety of direct and indirect effects of a number of physical and chemical factors, which include temperature, winds, vertical mixing, salinity, oxygen, pH and others.

Abstract

Cumulative human pressure on the Earth’s systems is changing both terrestrial and marine systems in significant ways – shifts in temperature, water levels, winds, extreme events and associated changes in habitat, flora and fauna. For industries, such as fisheries, and societies to remain viable despite the change they will need to adapt to it, as they have adapted to many other changes through time. There are wide range of research projects into the mechanisms that assist or hinder adaptation.

Abstract

Climate change can impact the pattern of marine biodiversity through changes in species’ distributions. However, global studies on climate change impacts on ocean biodiversity have not been performed so far. Our paper aims to investigate the global patterns of such impacts by projecting the distributional ranges of a sample of 1066 exploited marine fish and invertebrates for 2050 using a newly developed dynamic bioclimate envelope model. Our projections show that climate change may lead to numerous local extinction in the sub-polar regions, the tropics and semi-enclosed seas.

Abstract

Decision-makers in fisheries management are confronted with the challenge of how to respond to existing and predicted changes in ocean conditions that are likely to affect the stocks of fish they manage. In order to address climate change most research and thinking advises decision-makers to ensure that fisheries are well-managed and abundant in an ecosystem context. These policies can best allow fisheries to adapt to changing climate. To address climate change, decision-makers should carefully monitor changing conditions and potential changes in factors affecting fish stock abundance.

Abstract

Global climate change is impacting and will continue to impact marine and estuarine fish and fisheries. Data trends show global climate change effects ranging from increased oxygen consumption rates in fishes, to changes in foraging and migrational patterns in polar seas, to fish community changes in bleached tropical coral reefs. Projections of future conditions portend further impacts on the distribution and abundance of fishes associated with relatively small temperature changes.

Abstract

Adaptation is the adjustments that society or ecosystems make to limit negative effects of climate change. The Department’s approach to adaptation focuses on increasing the resilience of the Department’s assets, program activities, and mission responsibilities in response to climate vulnerabilities. Resilience is the ability to anticipate, prepare for, and adapt to changing conditions and withstand, respond to, and recover rapidly from disruptions.
