finding 24.6 : ocean-management-adaptations

In response to observed and projected climate impacts, some existing ocean policies, practices, and management efforts are incorporating climate change impacts. These initiatives can serve as models for other efforts and ultimately enable people and communities to adapt to changing ocean conditions.



This finding is from chapter 24 of Climate Change Impacts in the United States: The Third National Climate Assessment.

Process for developing key messages: A central component of the assessment process was the Oceans and Marine Resources Climate assessment workshop that was held January 23-24, 2012, at the National Oceanographic and Atmospheric Administration (NOAA) in Silver Spring, MD, and simultaneously, via web teleconference, at NOAA in Seattle, WA. In the workshop, nearly 30 participants took part in a series of scoping presentations and breakout sessions that began the process leading to a foundational Technical Input Report (TIR) entitled “Oceans and Marine Resources in a Changing Climate: Technical Input to the 2013 National Climate Assessment.”018aba6e-7bff-4124-ae9a-f2521e683bd1 The report, consisting of nearly 220 pages of text organized into 7 sections with numerous subsections and more than 1200 references, was assembled by 122 authors representing governmental agencies, non-governmental organizations, tribes, and other entities. The chapter author team engaged in multiple technical discussions via teleconferences that permitted a careful review of the foundational TIR018aba6e-7bff-4124-ae9a-f2521e683bd1 and of approximately 25 additional technical inputs provided by the public, as well as the other published literature, and professional judgment. The chapter author team met at Conservation International in Arlington, VA on 3-4 May 2012 for expert deliberation of draft key messages by the authors, wherein each message was defended before the entire author team before the key message was selected for inclusion in the report. These discussions were supported by targeted consultation with additional experts by the lead author of each message to help define “key vulnerabilities.”

Description of evidence base: The key message is supported by extensive evidence documented in the Oceans Technical Input Report018aba6e-7bff-4124-ae9a-f2521e683bd1 and additional technical inputs reports received as part of the Federal Register Notice solicitation for public input, as well as stakeholder engagement leading up to drafting the chapter. Scenarios suggest that adjustments to fish harvest regimes can improve catch stability under increased climate variability. These actions could have a greater effect on biological and economic performance in fisheries than impacts due to warming over the next 25 years.1d6e1e85-9d87-423d-acb9-98021e7c0a49 9a6b5247-ea62-4f66-a840-0f1d00712573 6a870b46-c599-4bf3-8dcf-32067fdd8393

New information and remaining uncertainties: Efforts are underway to enhance the development and deployment of science in support of adaptation, to improve understanding and awareness of climate-related risks, and to enhance analytic capacity to translate understanding into planning and management activities. While critical knowledge gaps exist, there is a wealth of climate- and ocean-related science pertinent to adaptation.018aba6e-7bff-4124-ae9a-f2521e683bd1

Assessment of confidence based on evidence: There is high confidence that adaptation planning will help mitigate the impacts of changing ocean conditions. But there is much work to be done to craft local solutions to the set of emerging issues in ocean and coastal areas.
