"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

"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. "

About the College Board Standards for College Success (CBSCS) The College Board Standards for College Success (CBSCS) define the knowledge and skills students need to develop and master in English language arts, mathematics and statistics, and science in order to be college and career ready. The CBSCS outline a clear and coherent pathway to Advanced Placement® (AP®) and college readiness with the goal of increasing the number and diversity of students who are prepared not only to enroll in college, but to succeed in college and 21st-century careers. The College Board has published these standards freely to provide a national model of rigorous academic content standards that states, districts, schools and teachers may use to vertically align curriculum, instruction, assessment and professional development to AP and college readiness. These rigorous standards: provide a model set of comprehensive standards for middle school and high school courses that lead to college and workplace readiness; reflect 21st-century skills such as problem solving, critical and creative thinking, collaboration, and media and technological literacy; articulate clear standards and objectives with supporting, in-depth performance expectations to guide instruction and curriculum development; provide teachers, districts and states with tools for increasing the rigor and alignment of courses across grades 6-12 to college and workplace readiness; and assist teachers in designing lessons and classroom assessments.
