The UN General Assembly has made a unanimous decision to start negotiations to establish an international, legally-binding instrument for the conservation and sustainable use of marine biological diversity within Areas Beyond National Jurisdiction (ABNJ). However, there has of yet been little discussion on the importance of this move to the ecosystem services provided by coastal zones in their downstream zone of influence.
I provide a selected survey of the literature on the effects of climate change on the biophysics and ecology of marine ecosystems and the fisheries that depend on them. First, I discuss the effects of warming, ocean acidification and deoxygenation on marine life. Second, I describe how the projected changes in the biophysics of the ocean is likely to affect the economics and management of ocean fisheries.
Climate change will have a profound impact on human and natural systems, and will also impede economic growth and sustainable development. In this book, leading experts from around the world discuss the challenges and opportunities in building a climate resilient economy and society. The chapters are organised in three sections. The first part explores vulnerability, adaptation and resilience, whilst Part II examines climate resilience-sectoral perspectives covering different sectors such as agriculture, fisheries, marine ecosystems, cities and urban infrastructure, drought prone areas, and renewable energy. In the final part, the authors look at Incentives, institutions and policy, including topics such as carbon pricing, REDD plus, climate finance, the role of institutions and communities, and climate policies. Combining a global focus with detailed case studies of a cross section of regions, countries and sectors, this book will prove to be an invaluable resource.
The effects of climate change on marine ecosystems are accelerating. Identifying and protecting areas of the ocean where conditions are most stable may provide another tool for adaptation to climate change. To date, research on potential marine climate refugia has focused on tropical systems, particularly coral reefs. We examined a northeast Pacific temperate region – Canada’s Pacific – toidentify areas where physical conditions are stable or changing slowly. We analyzed the rate and consistency of change for climatic variables where recent historical data were available for the whole region, which included sea surface temperature, sea surface height, and chlorophyll a.
