• The Philippines is victim of geography, poor infrastructure, poverty

    Owing to its location and geography, the Philippines is one of the most natural disaster-prone countries in the world. On average the country experiences nine major typhoons and 900 earthquakes annually, and it has twenty-five active volcanoes. Poor infrastructure and pervasive poverty exacerbate the impact of disasters, making them even more deadly and destructive. “In a cruel cycle, poverty and underdevelopment make disasters worse, and disasters make poverty and underdevelopment worse,” one observer notes.

  • Past as prologue: Insights from past natural disasters relevant today

    The increasing frequency and intensity of natural disasters constitute a daunting challenge to modern society, which is characterized by a heavy infrastructure and increasing population density. Until now, coping with natural disasters has involved expensive state intervention and technology-aided approaches, but researchers believes that the past contains a wealth of unexploited resources which could also provide solutions to the problems communities face when dealing with need to cope with, and recover from, natural disasters.

  • Climate scientists say renewables are not enough

    Some of the world’s top climatologists have declared their support for nuclear energy as a complementary energy source, alongside wind and solar as energy, which would cut fossil fuel pollution and reduce the growth of global warming. The scientists say that opposing fossil fuels and promoting renewable energy sources offer but a limited solution.

  • Philippines prepares for worse disasters to come

    On average, the Philippines experiences about twenty typhoons a year, including three super-typhoons and many incidents of flooding, drought, earthquakes, tremors, and occasional volcanic eruptions, making the country one of the most naturally disaster-prone areas in the world. Filipino government agencies, with the help of international disaster and relief agencies, have created new strategies for disaster preparedness, response, and mitigation which may well have potential applications in other parts of the world. As the impact of climate change grows more pronounced, the Philippines is becoming a hothouse for developing new methods and systems in the growing business of disaster relief.

  • Sunlight-activated nanogrid breaks down pollutants in water

    Oil spills do untold damage to the environment — to the waters they pollute and to marine and other wildlife. The Deepwater Horizon spill in the Gulf of Mexico in 2010, for example, the largest accidental marine oil spill in the history of the petroleum industry, flowed unabated for three months. Typically, such oil spills are extraordinarily difficult to clean up. Soon, however, the process may become infinitely easier and ecologically friendly, the result of a new invention — “nanogrid” — a large net consisting of metal grids made of a copper tungsten oxide, that, when activated by sunlight, can break down oil from a spill, leaving only biodegradable compounds behind.

  • Chelyabinsk meteor explosion a "wake-up call," scientists warn

    Three new studies have revealed details of the meteor that exploded above Russian city, Chelyabinsk, in February this year. Their findings provide information about the meteor’s origin, trajectory, power and damage by the airburst (the shock wave that travelled through the air from the explosion). These findings may help to refine theoretical models about the likely frequency of such events, the potential damage they could cause and hazard mitigation strategies needed for planetary protection.

  • Wildfire science returns to California’s Rim Fire

    The challenging job of managing wildfires rests with other agencies, but the U.S. Geological Survey (USGS) provides the underlying science for sound land management decisions, before, during, and after wildfires. The USGS role studying natural hazards such as floods, landslides, earthquakes, and volcanoes is well known, but fewer people are aware of the USGS scientific work in major wildfire events, which are one of the most regular and sometimes most devastating natural hazards in the West.

  • Safe long-term CO2 storage possible

    Since 2004, the German Research Centre for Geosciences (GFZ) has led an international research network to investigate the geological storage of the greenhouse gas (CCS, for carbon capture and storage). GFZ’s scientists say that their work at the Ketzin site, 40 km west of Berlin, has shown that geological CO2 storage on a pilot scale can be done safely and reliably.

  • Scientists: we should prepare for hell and high water

    An international team of climate and social scientists say a new approach to climate preparedness is essential to help people adjust to coming changes. As climate-driven changes get more pronounced, people everywhere will have to adjust. In this week’s issue of the journal Science, an international group of researchers urge the development of science needed to manage climate risks and capitalize on unexpected opportunities.

  • Reducing volume of nuclear waste by 90 percent possible

    Engineers have developed a way significantly to reduce the volume of some higher activity wastes, which will reduce the cost of interim storage and final disposal. The researchers have shown that mixing plutonium-contaminated waste with blast furnace slag and turning it into glass reduces its volume by 85-95 percent. It also effectively locks in the radioactive plutonium, creating a stable end product.

  • Water shortage hobbles expansion of shale gas drilling

    Many point to the large reserves of shale gas as promising U.S. energy independence in the near future. Extracting shale gas, however, requires huge amounts of water, and growing water shortages have already led to conflicts over water use between shale gas developers and farmers. Such conflicts are only going to intensify.

  • Leading climate scientists urge support for nuclear power

    Four of the world’s leading climate scientists have urged environmentalists to support the continuing development of nuclear power as one of the ways to reduce fossil fuel pollution, saying wind and solar energy will not be enough to head off dangerous acceleration of global warming. This is an important point because environmentalists agree that global warming is a threat to ecosystems and humans, but many of the same environmentalists oppose nuclear power, arguing that new forms of renewable energy will be sufficient to meet the world’s need for power within the next few decades.

  • Planet’s arable land rapidly degrading

    Great civilizations have fallen because they failed to prevent the degradation of the soils on which they were founded. The modern world could suffer the same fate. A new study describes how the productivity of many lands has been dramatically reduced as a result of soil erosion, accumulation of salinity, and nutrient depletion.

  • Resources on disaster preparedness, resilience

    One year after Superstorm Sandy hit the eastern United States, local, state, and federal agencies as well as community groups and businesses are working to strengthen the U.S.s resilience to future disasters. A National Research Council (NRC) has issues a series of studies and reports, and has put together workshops and study groups, which should advance the national conversation on preparedness and resilience.

  • Rising temperatures threaten Salt Lake City’s water supply

    In an example of the challenges water-strapped Western cities will face in a warming world, new research shows that every degree Fahrenheit of warming in the Salt Lake City region could mean a 1.8 to 6.5 percent drop in the annual flow of streams that provide water to the city. By midcentury, warming Western temperatures may mean that some of the creeks and streams that help slake Salt Lake City’s thirst will dry up several weeks earlier in the summer and fall.
