• Sea-level records reveal tight correlation between ice volume and polar temperature

    During the last few million years, global ice-volume variability has been one of the main feedback mechanisms in climate change, because of the strong reflective properties of large ice sheets. Ice volume changes in ancient times can be reconstructed from sea-level records; a new study has revealed a rapid response between global temperature and ice volume/sea-level, which could lead to sea-levels rising by over one meter

  • In 2009, engineers predicted surge threats to N.Y.-N.J. and offered detailed mitigation measures

    The leaders of the U.S. top engineering association, reflecting on the destruction inflicted by Superstorm Sandy, say that more than three years ago the association presented studies showing that a devastating storm surge in the region was all but inevitable; participants in the 30-31 March 2009 American Society of Civil Engineers (ASCE) conference called on NYC officials seriously to consider whether to install surge barriers or tide gates in New York Harbor to protect the city

  • New book discusses storm surge protection for New York City

    A new book from American Society of Civil Engineers (ASCE), to be published on 3 December, includes sixteen papers exploring the development of storm surge barriers to protect New York City and nearby New Jersey from the effects of a future deluge

  • Reasons of deadly 2010 India flood identified; findings could improve warnings

    On the night of 5 August 2010, as residents slept, water began rushing through Leh, an Indian town in a high desert valley in the Himalayas; average total rainfall in the area for August is about a half-inch; during this 24-hour period, more than eight inches fell, causing severe damage and leaving 193 dead, hundreds missing, and thousands homeless; scientists studied satellite images and what is called re-analysis data to piece together what happened to create such a torrential downpour; the results will allow for improved warnings of flash floods

  • In Pennsylvania, the U.S. mecca of fracking, more scientific research is urged

    Hydraulic fracturing or fracking is a controversial method to extract natural gas or petroleum from subterranean shale by using pressurized water to blast it open; proponents of fracking have noted its potential for helping the United States achieve energy independence while also stimulating the economy and creating jobs; these proponents have met stiff resistance from environmental groups that claim fracking can result in air and water pollution and have adverse human health effects

  • Relief organizations step up their efforts in wake of Hurricane Sandy

    In response to Superstorm Sandy, the Red Cross, Salvation Army, and other organizations have combined for the largest relief effort since Hurricane Katrina; the Red Cross has raised more than $117 million across ten states in donations and pledges

  • “Groundwater inundation” doubles previous predictions of flooding with future sea level rise

    Scientists published a study today showing that besides marine inundation (flooding), low-lying coastal areas may also be vulnerable to “groundwater inundation,” a factor largely unrecognized in earlier predictions on the effects of sea level rise (SLR)

  • CIA-commissioned climate change report outlines perils for U.S. national security

    U.S. national security leaders believe that the accelerating pace of climate change will place severe strains on U.S. military and intelligence agencies in coming years; the reason, according the National Research Council, the U.S. top scientific research body: climate changes will trigger increasingly disruptive developments around the world; a 206-page National Research Council study, commissioned by the CIA and other U.S. intelligence services, concludes that states will fail, large populations subjected to famine, flood, or disease will migrate across international borders, and national and international agencies will not have the capacity or resources to cope with the resulting conflicts and crises

  • Sandy’s damage in New York State could reach $33 billion

    Governor Andrew Cuomo said yesterday that the damage in New York state from Superstorm Sandy could reach $33 billion; a firm specializing in damage estimate had earlier estimated that Sandy might have caused between $30 billion and $50 billion in economic losses from the Carolinas to Maine; these estimates include property damage, lost business, and extra living expenses; Cuomo’s estimate, which are based on studies by experts in his administration, are likely push these figures higher

  • 2002 Alaska earthquake helped set standards for buildings, bridges

    The Denali 7.9 earthquake that hit Alaska in 2002 was the largest to hit the United States in more than 150 years, and the strongest ever recorded in Alaska; no one was killed and only a few people were injured; the only severe damage the earthquake caused was to a few highways, but the damage was not significant enough to close them; the earthquake set new national standards for building bridges as well as giving seismologists a better understanding of how earthquakes affect frozen ground

  • Future warming likely to be on high side of climate projections: analysis

    Climate model projections showing a greater rise in global temperature are likely to prove more accurate than those showing a lesser rise, according to a new analysis by scientists at the U.S. National Center for Atmospheric Research (NCAR); NCAR says that the findings could provide a breakthrough in the longstanding quest to narrow the range of global warming expected in coming decades and beyond

  • Nor'easter batters NYC, New Jersey

    A nor’easter battered New York and New Jersey on Wednesday with rain and wet snow, plunging homes back into darkness, stopping commuter trains, and inflicting yet more misery on thousands of people still trying to recover from Superstorm Sandy; ordinarily, the nor’easter would not pose major problems, but this was not the case yesterday, as the storm hit an area where electrical systems were still fragile and many of Sandy’s victims still busy cleaning their homes and coping with deepening cold

  • MIT researchers develop method to help communities plan for climate risk

    As the devastation left by Sandy continues to reverberate, decision-makers at every level are asking: How can we be better prepared? MIT researchers developed a tool to assess regional risks of climate change and potential impacts on local infrastructure and planning; the tool helps policymakers, city planners, and others see the possible local effects of climate change, such as long-term temperature and precipitation changes, allowing local planners to evaluate risks, and how these risks could shape crops, roads, and energy infrastructure

  • Dealing with power outages more efficiently

    When there is a power failure, the utility companies, public officials and emergency services must work together quickly; researchers have created a new planning software product that enables all participants to be better prepared for emergency situations

  • Building material of millennium: Autoclave Aerated Concrete

    Although widespread rebuilding in the hard-hit New York metro region from Hurricane Sandy has not yet begun, New Jersey Institute of Technology (NJIT) scientists say when the hammers start swinging, it is time to look at autoclaved aerated concrete; the material, best known as AAC, has been heralded as the building material of the new millennium
