    "Science 25 November 2011: Vol. 334 no. 6059 pp. 1052-1053 DOI: 10.1126/science.334.6059.1052 * News Focus Adaptation to Climate Change Adaptation to Climate Change Time to Adapt to a Warming World, But Where's the Science? 1. Richard A. Kerr With dangerous global warming seemingly inevitable, users of climate information-from water utilities to international aid workers-are turning to climate scientists for guidance. But usable knowledge is in short supply. Figure View larger version: * In this page * In a new window Adapt to that. Climate will change, but decision-makers want to know how, where, and when. "CREDIT: KOOS VAN DER LENDE/NEWSCOM" DENVER, COLORADO-The people who brought us the bad news about climate change are making an effort to help us figure out what to do about it. As climate scientists have shown, continuing to spew greenhouse gases into the atmosphere will surely bring sweeping changes to the world-changes that humans will find it difficult or impossible to adapt to. But beyond general warnings, there is another sort of vital climate research to be done, speakers told 1800 attendees at a meeting here last month. And so far, they warned, researchers have delivered precious little of the essential new science. At the meeting, subtitled "Climate Research in Service to Society,"* the new buzzword was "actionable": actionable science, actionable information, actionable knowledge. "There's an urgent need for actionable climate information based on sound science," said Ghassem Asrar, director of the World Climate Research Programme, the meeting's organizer based in Geneva, Switzerland. What's needed is not simply data but processed information that an engineer sizing a storm-water pipe to serve for the next 50 years or a farmer in Uganda considering irrigating his fields can use to make better decisions in a warming world. Researchers preparing for the next international climate assessment, due in 2013, delive

    Key Findings Current Coastal Management Challenges Current coastal management challenges are worsening. Top management challenges will be exacerbated by climate change. Current management challenges make adaptation planning and decision-making difficult. Climate Change Concerns, Knowledge, and Actions Attitudes and knowledge about climate change are strongly supportive of adaptation action. Attention to adaptation has increased markedly over the past five years. Adaptation planning and implementation is still in the very early stages. There is limited familiarity with innovative adaptation approaches. Information, Technical Assistance, and Training Needs Organizational missions, job responsibilities, and legal requirements shape common information use. Ease of access to information is the overriding determinant of information use. Specific information needs differ by professional group. Critical opportunities exist to meet coastal professionals' information, technical assistance, and training needs Survey Background Decision-makers in California's (CA) coastal counties recognize that climate change will impact their communities and coastline. Yet, coastal CA communities are at different stages in developing and/or implementing climate change adaptation plans. During the Summer of 2012, USC Sea Grant, in partnership with 14 other CA-based organizations (listed below), launched a survey to understand the needs and barriers coastal communities have in planning for climate change in order to develop appropriate trainings and technical assistance for communities and determine the best way to link communities to resources and tools already available.

Climate Change, Keystone Predation, and Biodiversity Loss - 0 views

    "Abstract Climate change can affect organisms both directly via physiological stress and indirectly via changing relationships among species. However, we do not fully understand how changing interspecific relationships contribute to community- and ecosystem-level responses to environmental forcing. I used experiments and spatial and temporal comparisons to demonstrate that warming substantially reduces predator-free space on rocky shores. The vertical extent of mussel beds decreased by 51% in 52 years, and reproductive populations of mussels disappeared at several sites. Prey species were able to occupy a hot, extralimital site if predation pressure was experimentally reduced, and local species richness more than doubled as a result. These results suggest that anthropogenic climate change can alter interspecific interactions and produce unexpected changes in species distributions, community structure, and diversity. "

    "What are the impacts of ocean acidification on key benthic (seabed) ecosystems, communities, habitats, species and their life cycles? The average acidity (pH) of the world's oceans has been stable for the last 25 million years. However, the oceans are now absorbing so much man made CO2 from the atmosphere that measurable changes in seawater pH and carbonate chemistry can be seen. It is predicted that this could affect the basic biological functions of many marine organisms. This in turn could have implications for the survival of populations and communities, as well as the maintenance of biodiversity and ecosystem function. In the seas around the UK, the habitats that make up the seafloor, along with the animals associated with them, play a crucial role in maintaining a healthy and productive marine ecosystem. This is important considering 40% of the world's population lives within 100km of the coast and many of these people depend on coastal systems for food, economic prosperity and well-being. Given that coastal habitats also harbour incredibly high levels of biodiversity, any environmental change that affects these important ecosystems could have substantial environmental and economical impacts. During several recent international meetings scientific experts have concluded that new research is urgently needed. In particular we need long-term studies that determine: which organisms are likely to be tolerant to high CO2 and which are vulnerable; whether organisms will have time to adapt or acclimatise to this rapid environmental change; and how the interactions between individuals that determine ecosystem structure will be affected. This current lack of understanding is a major problem as ocean acidification is a rapidly evolving management issue and, with an insufficient knowledge base, policy makers and managers are struggling to formulate effective strategies to sustain and protect the marine environment in the face of ocean acidification."

Communities Under Climate Change - 0 views

    perspective "The distribution of species on Earth and the interactions among them are tightly linked to historical and contemporary climate, so that global climate change will transform the world in which we live. Biological models can now credibly link recent decadal trends in field data to climate change, but predicting future impacts on biological communities is a major challenge. Attempts to move beyond general macroecological predictions of climate change impact on one hand, and observations from specific, local-scale cases, small-scale experiments, or studies of a few species on the other, raise a plethora of unanswered questions. On page 1124 of this issue, Harley (1) reports results that cast new light on how biodiversity, across different trophic levels, responds to climate change. "

Green Ambassadors » Results of Rise Above Plastics: 2009 - 0 views

  •  
    RISE ABOVE PLASTIC (RAP) SUCCESS! Green Ambassadors, in partnership with The Surfrider Foundation and The Algalita Marine Research Foundation, created the Rise Above Plastics Program, a student speaker series that encourages Los Angelenos to curb their single-use habits. Through the program, students learn about the impact of plastics on our lives and the environment, including plastic marine debris, chemicals and toxins. Students spread the word to their peers and the community by delivering engaging presentations that encourage practical solutions. In addition to learning about the inherent problems of living in a throwaway society, students learn the value of teamwork and polish their public speaking and presentation skills. In 2009, nearly 20 students participated in the program, delivering 30 presentations to more than 850 students and community members!

In Person: Finding a Path from Oceanography to a Science Communication Career - Science... - 1 views

  •  
    About 2 years into my Ph.D., I began to realize that I couldn't imagine my life as a researcher in 5 years' time and to wonder why that might be. Why wasn't I enthusiastic about where my first, second, or even third postdoc would be and into which new and fascinating areas of oceanography they would lead me? It wasn't that I didn't enjoy my particular area of research. I did. I still do. But I had begun to realize that my heart (and perhaps my skills) lay outside academic research. I felt like I wanted to be a communicator of leading-edge science but not necessarily a doer of it myself. Could I admit that and still say I had a passion for science?

    "Washington, DC - 03/12/2012 - The Pew Environment Group commended Sens. John Kerry (D-Mass.), Olympia J. Snowe (R-ME), John D. Rockefeller (D-WV), Scott Brown (R-MA), and Sheldon Whitehouse (D-RI) today for introducing the Fisheries Investment and Regulatory Relief Act (FIRRA). A companion bill is expected in the House by Reps. Barney Frank (D-MA) and Frank Guinta (R-NH). This bipartisan legislation would ensure that key programs critical to sustainably managing ocean fish populations, and the fishermen and communities that depend on them, would receive increased and sustained funding.

Experts Agree Global Warming Is Melting the World Rapidly - 0 views

    Experts Agree Global Warming Is Melting the World Rapidly Richard A. Kerr Forty-seven glaciologists have arrived at a community consensus over all the data on what the past century's warming has done to the great ice sheets: a current annual loss of 344 billion tons of glacial ice, accounting for 20% of current sea level rise. Greenland's share-about 263 billion tons-is roughly what most researchers expected, but Antarctica's represents the first agreement on a rate that had ranged from a far larger loss to an actual gain. The new analysis, published on page 1183 of this week's issue of Science, also makes it clear that losses from Greenland and West Antarctica have been accelerating, showing that some ice sheets are disconcertingly sensitive to warming.

Rebuilding Wetlands by Managing the Muddy Mississippi - 0 views

    Science 3 February 2012: Vol. 335 no. 6068 pp. 520-521 DOI: 10.1126/science.335.6068.520 News Focus Ecology Rebuilding Wetlands by Managing the Muddy Mississippi Carolyn Gramling Coastal managers and scientists have struggled to find ways to restore water flow through the wetlands of the Mississippi delta and bring back the sediment, supply of which has been cut in half by humanmade river channels, levees, and dams intended to control the river and save coastal communities from flooding. The U.S. Army Corps of Engineers opened the Morganza spillway during the 2011 Mississippi River floods to divert floodwaters, which offered a rare opportunity to conduct a large-scale natural experiment in real time. The floodwaters did carry enough sediment to help rebuild the wetlands, but that material didn't always stay where it could do the most good. However, researchers gained valuable insights-including ideas about how spillway design can help produce more targeted sediment deposits, and what volume of flow through the spillways might be required for effective wetland rebuilding.

Science out of context - Opinion - The Boston Globe - 0 views

  •  
    "Our experience highlights that virtually all of scientists' deliberative communications, including e-mails and attached documents, can be subject to legal proceedings without limitation. Incomplete thoughts and half-finished documents attached to e-mails can be taken out of context and impugned by people who have a motive for discrediting the findings In addition to obscuring true scientific findings, this situation casts a chill over the scientific process. In future crises, scientists may censor or avoid deliberations, and more importantly, be reluctant to volunteer valuable expertise and technology that emergency responders don't possess. Open, scientific deliberation is critical to science. It needs to be protected in a way that maintains transparency in the scientific process, but also avoids unnecessary intrusions that stifle research vital to national security and economic interests."
