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.

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.

Global Warming Materials for Educators Below is a list of Global Warming materials for educators produced by the Union of Concerned Scientists' (UCS) Climate Change Program. All of these materials are based on published, peer-reviewed science, and have themselves been peer-reviewed by scientific experts in the relevant fields.

The shallow water reefs of the Coral Triangle, which stretches across Indonesia and north through the Philippines, host the world's greatest diversity of corals, fish, crustaceans, mollusks, and marine plant species. Now preliminary results from a joint Indonesian-U.S. marine survey indicate that the biodiversity runs deep. A remotely operated vehicle has captured stunning images of massive corals, as well as unusual crustaceans and fish living at depths never before surveyed, thousands of meters below the surface. And mapping of that sea floor has turned up a huge, previously unknown volcano.

Science On a Sphere Well-crafted visualizations provide unique and powerful teaching tools Science On a Sphere® is a large visualization system that uses computers and video projectors to display animated data onto the outside of a sphere. Researchers at NOAA developed Science On a Sphere® as an educational tool to help illustrate Earth System science to people of all ages. Animated images of complex processes such as ocean currents, sea level rise, and ocean acidification are used to to enhance the public's understanding of our dynamic environment. Ocean Acidification on Science On a Sphere® The movies below were developed for use on Science On a Sphere® and show computer model simulations of surface ocean pH and carbonate mineral saturation state for the years 1895 to 2094. The first movie shows a computer recreation of surface ocean pH from 1895 to the present, and it forecasts how ocean pH will drop even more between now and 2094. Dark gray dots show cold-water coral reefs. Medium gray dots show warm-water coral reefs. You can see that ocean acidification was slow at the beginning of the movie, but it speeds up as time goes on. This is because humans are releasing carbon dioxide faster than the atmosphere-ocean system can handle.

Three Historic Blowouts 1. Lauren Schenkman Figure Mexico 1979 "CREDIT: NOAA" The decade from 1969 to 1979 witnessed three massive spills from offshore oil wells around the world. Here is how they compare in size and impact. IXTOC 1 The biggest well-related spill was triggered on 3 June 1979, when a lack of drilling mud allowed oil and gas to shoot up through the 3.6-km-deep IXTOC 1 exploratory well, about 80 km offshore in the southern Gulf of Mexico. The initial daily outflow of 30,000 barrels of oil was eventually reduced to 10,000 barrels. The well was finally capped more than 9 months later. Mexico's state-owned oil company, PEMEX, treated the approximately 3.5-million-barrel spill with dispersants. U.S. officials had a 2-month head start to reduce impacts to the Texas coastline. Figure North Sea 1977 "CREDIT: WALLY FONG/AP PHOTO" Ekofisk The first major spill in the North Sea resulted in the release of 202,000 barrels of oil about 250 km off the coast of Norway. The 22 April 1977 blowout caused oil to gush from an open pipe 20 m above the sea surface. The well was capped after a week. Between 30% and 40% of the spill evaporated almost immediately. Rough waters broke up the slick before it reached shore. Figure Santa Barbara 1969 "CREDIT: BETTMANN/CORBIS" Santa Barbara A blown well 1 km below the sea floor and 9 km off the coast of Santa Barbara, California, spewed out a total of 100,000 barrels of oil. The initial eruption occurred on 28 January 1969, and the well was capped by mud and cement on 7 February, but the pressure forced oil through sea floor fissures until December. The oil contaminated 65 km of coastline. At least 3700 birds are known to have died, and commercial fishing in the area was closed until April.

The bad news just got worse: A new study finds that reining in greenhouse gas emissions in time to avert serious changes to Earth's climate will be at best extremely difficult. Current goals for reducing emissions fall far short of what would be needed to keep warming below dangerous levels, the study suggests. To succeed, we would most likely have to reverse the rise in emissions immediately and follow through with steep reductions through the century. Starting later would be far more expensive and require unproven technology.
