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. \r\nThe 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.”" references: - href: http://52.38.26.42:8080/reference/006ce4db-d72c-400a-a409-c6a536e55664.yaml uri: /reference/006ce4db-d72c-400a-a409-c6a536e55664 - href: http://52.38.26.42:8080/reference/018aba6e-7bff-4124-ae9a-f2521e683bd1.yaml uri: /reference/018aba6e-7bff-4124-ae9a-f2521e683bd1 - href: http://52.38.26.42:8080/reference/128194f0-1295-4321-a7bf-a8dee1fc2247.yaml uri: /reference/128194f0-1295-4321-a7bf-a8dee1fc2247 - href: http://52.38.26.42:8080/reference/3d9112b9-6aa1-4614-9599-6966c9591ef9.yaml uri: /reference/3d9112b9-6aa1-4614-9599-6966c9591ef9 - href: http://52.38.26.42:8080/reference/3f1b7fd7-3b1b-4b7f-8b68-802eddde7a27.yaml uri: /reference/3f1b7fd7-3b1b-4b7f-8b68-802eddde7a27 - href: http://52.38.26.42:8080/reference/8b09bbe8-9f42-412e-a4d6-ef4889f56556.yaml uri: /reference/8b09bbe8-9f42-412e-a4d6-ef4889f56556 - href: http://52.38.26.42:8080/reference/b09adbe5-6a17-4d3c-ab96-b3d9e306af67.yaml uri: /reference/b09adbe5-6a17-4d3c-ab96-b3d9e306af67 - href: http://52.38.26.42:8080/reference/b78bfacb-e00f-4af6-8ad7-dff157f8b8b4.yaml uri: /reference/b78bfacb-e00f-4af6-8ad7-dff157f8b8b4 - href: http://52.38.26.42:8080/reference/c767db68-2732-424b-9dc6-e6bf94bc7a8e.yaml uri: /reference/c767db68-2732-424b-9dc6-e6bf94bc7a8e - href: http://52.38.26.42:8080/reference/d7265962-536c-4002-b3a7-1ed6e8841753.yaml uri: /reference/d7265962-536c-4002-b3a7-1ed6e8841753 - href: http://52.38.26.42:8080/reference/f516a114-4604-4062-a1b3-e70a4cbbba9e.yaml uri: /reference/f516a114-4604-4062-a1b3-e70a4cbbba9e report_identifier: nca3 statement: 'Significant habitat loss will continue to occur due to climate change for many species and areas, including Arctic and coral reef ecosystems, while habitat in other areas and for other species will expand. These changes will consequently alter the distribution, abundance, and productivity of many marine species.' type: finding uncertainties: "Regional and local variation is, again, a major component of the remaining uncertainties. Different areas, habitats, and species are responding differently and have very different adaptive capacities. Those species that are motile will certainly respond differently, or at least at a different rate, by changing distribution and migration patterns, compared to species that do not move, such as corals. \r\nAlthough it is clear that some fish stocks are moving poleward and to deeper water, how far they will move and whether most species will move remains unclear. A key uncertainty is the extent to which various areas will benefit from range expansions of valuable species or increases in productivity, while other areas will suffer as species move away from previously productive areas. The loss of critically important habitat due to climate change will result in changes in species interactions that are difficult to predict. \r\n" uri: /report/nca3/chapter/oceans-marine-resources/finding/marine-habitat-loss-and-expansion url: ~
