. . . the edited collection makes for an excellent contribution to the literature on ocean acidification. Many of the contributions address issues that have not yet received much scholarly attention, while those that cover more familiar topics provide new perspectives and track recent developments in the legal and policy response to ocean acidification. Research Handbook on Ocean Acidification Law and Policy certainly succeeds in providing a navigational guide to the tangled currents of responding to ocean acidification at the global, regional and national levels. For this, the editors and the contributors are to be commended. Hopefully this guide will not only be the basis for further scholarly investigation of the different challenges ocean acidification presents, but will also be read by policymakers at different levels of governance and go some way to steering them towards more effective responses to continuing ocean acidification. -- Philipp Peter Nickels, The International Journal of Marine and Coastal Law Like climate change, ocean acidification is caused by rising carbon dioxide emissions. However, unlike the former, its adverse impacts on the marine ecosystems globally, biological diversity, human rights and food security are largely unaddressed. This Research Handbook draws attention to this gap in law and policy; a gap in dire need of closing. The opportunities, the book suggests, lie in regional, national and sub-national responses. The success depends on whether governments rise to this major challenge. In this context, the book is an alarm bell. -- Christina Voigt, University of Oslo, Norway
