    Science 25 November 2011: Vol. 334 no. 6059 p. 1039 DOI: 10.1126/science.334.6059.1039-b * News of the Week Random Sample Mongolia's 'Ice Shield' Figure View larger version: * In this page * In a new window Hot zone. Flanked by desert, Ulan Bator will be cooled in summer by an "ice shield." "CREDIT: BRÜCKE-OSTEUROPA/WIKIPEDIA" As the coldest capital on Earth, you might think the last thing Ulan Bator needs is more ice. But that is just what it's about to get under a geoengineering trial aimed at "storing" freezing winter temperatures to cool and water the city during the summer. At the end of this month, engineers will drill a series of bores through the ice on the Tuul River, pump up water from below, and spray it on the surface where it will freeze. This process will be repeated throughout the winter, adding layer after layer to create a chunk of ice that will be 7 or 8 meters thick by the spring. It's an attempt to artificially create the ultra-thick slabs-known as naleds in Russian-that occur naturally in far northern climes when rivers or springs push through surface cracks. Nomads have long made their summer camps near such phenomena, which melt much later than normal ice. Flanked by desert and plagued by summer temperatures that can rise close to 40°C, Ulan Bator's municipal government hopes the $724,000 experiment will create a cool microclimate and provide fresh water as the naled melts. ECOS & EMI, the Anglo-Mongolian company behind the plan, has still greater ambitions. "Everyone is panicking about melting glaciers and icecaps, but nobody has yet found a cheap, environmentally friendly alternative," says Robin Grayson, a geologist in Ulan Bator for ECOS & EMI. "If you know how to manipulate them, naled ice shields can repair permafrost and build cool parks in cities." The process, Grayson says, can be replicated anywhere where winter temperatures fall below −5°C for at least a couple of months.

Aerosols Altered Asian Monsoons - 0 views

    Aerosols Altered Asian Monsoons Summer monsoons provide much of the water for farming on the Indian subcontinent, but the pattern of rain shifted dramatically during the last half of the 20th century. In a study appearing online 29 September in Science, researchers pin the blame on soot and other aerosols from human activities. From 1951 to 1999, central-northern India became drier while Pakistan, northwestern India, and southern India got wetter. To determine whether these changes were due to natural variability or human interference (greenhouse gases or aerosols), climate scientists Massimo Bollasina, Yi Ming, and V. Ramaswamy of the Geophysical Fluid Dynamics Laboratory/NOAA in Princeton, New Jersey, compared the history of rainfall with simulations that singled out each climate "forcing" factor to observe its impact. Although greenhouse gases would have increased rainfall over north-central India, the aerosols, they found, caused the "very pronounced drying trend," Ming says. Here's why: Under normal conditions, the northern hemisphere receives more energy from the sun from June to September; that imbalance drives the ocean-atmosphere circulation that powers the monsoons. But atmospheric aerosols shaded the northern hemisphere relative to the southern hemisphere, altering the energy balance between the two-weakening the circulation and altering where the rain falls.

Photo Credit: © Brian Skerry, www.brianskerry.com Despite covering 70 percent of the earth's surface, the ocean doesn't often make it into the news. But when it does, it makes quite a splash (so to speak). Here are the top ten ocean stories we couldn't stop talking about this year, in no particular order. Add your own in the comments! 2012: The Year of the Squid From the giant squid's giant eyes (the better to see predatory sperm whales, my dear), to the vampire squid's eerie diet of remains and feces, the strange adaptations and behavior of these cephalopods amazed us all year. Scientists found a deep-sea squid that dismembers its own glowing arm to distract predators and make a daring escape. But fascinating findings weren't relegated to the deep: at the surface, some squids will rocket themselves above the waves to fly long distances at top speeds. James Cameron Explores the Deep Sea Filmmaker James Cameron has never shied away from marine movie plots (See: Titanic, The Abyss), but this year he showed he was truly fearless, becoming the first person to hit the deepest point on the seafloor (35,804 feet) in a solo submarine. While he only managed to bring up a single mud sample from the deepest region, he found thriving biodiversity in the other deep-sea areas his expedition explored, including giant versions of organisms found in shallow water. Schooling sardines form a "bait ball." Small fish, such as these schooling sardines, received well-deserved attention for being an important part of the food chain in 2012.

    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. Survey Partners USC Sea Grant California Sea Grant Center for Ocean Solutions, Stanford University California Nevada Applications Program (CNAP) at the Scripps Institution of Oceanography, University of California, San Diego through the NOAA Regional Integrat

    Endangered Species Bulletin The U.S. Fish and Wildlife Service offers the quarterly Endangered Species Bulletin, with information on rulemakings, recovery plans and activities, conservation partnerships, research developments, and a variety of other issues. The Summer 2009 issue was focused entirely oceans and includes articles on corals, sea turtles, the Hawaiian Monk Seal, and more.
