• The natural relationship between CO2 concentrations and sea level means that sea level will continue to rise

    By comparing reconstructions of atmospheric CO2 concentrations and sea level over the past forty million years, researchers have found that greenhouse gas concentrations similar to the present (almost 400 parts per million) were systematically associated with sea levels at least nine meters above current levels

  • Study warns of more powerful quakes in the Himalayas

    A research team has discovered that massive earthquakes in the range of 8 to 8.5 magnitudes on the Richter scale have left clear ground scars in the central Himalayas;this discovery has important implications for the area along the front of the Himalayan Mountains, given that the region has a population density similar to that of New York City

  • Fiscal cliff discussions get in way of post-Sandy relief measure

    The post-Sandy rebuilding effort in the northeast has been stalled by the debate going on in Congress about a solution to the national debt

  • Potentially devastating asteroid collision in 2040 not likely to happen

    A team of astronomers from the University of Hawaii’s Institute for Astronomy (IfA) have confirmed that the chance of asteroid 2011 AG5 impacting Earth in 2040 is no longer a significant risk — prompting a collective sigh-of-relief; previously, scientists estimated that the risk of this 140-meter-diameter (about the length of two American football fields) asteroid colliding with the Earth – and releasing about 100 megatons of energy — was as high as one in 500

  • Regulating geo-engineering schemes

    With policymakers and political leaders increasingly unable to combat global climate change, more scientists are considering the use of manual manipulation of the environment to slow warming’s damage to the planet; some legal scholars argue that the legal ramifications of this kind of geo-engineering need to be thought through in advance and a global governance structure put in place soon to oversee these efforts

  • Bricks made from paper waste

    Spanish researchers have mixed waste from the paper industry with ceramic material used in the construction industry; the result is a brick that has low thermal conductivity meaning it acts as a good insulator; its mechanical resistance, however, still requires improvement

  • Some geo-engineering approaches to combat climate change may not work

    Numerous geo-engineering schemes have been suggested as possible ways to reduce levels of the greenhouse gas carbon dioxide in the atmosphere and so reduce the risk of global warming and climate change; one such technology involves dispersing large quantities of iron salts in the oceans to fertilize otherwise barren parts of the sea and trigger the growth of algal blooms and other photosynthesizing marine life; seeding the oceans with iron, however, may not address carbon emissions

  • City is sued over ban on fracking

    An industry group representing oil and gas companies filed a lawsuit Monday against a city in Colorado which has banned hydraulic fracturing; fracking has increased U.S. energy production, but it has also caused contamination of ground water; scientists say fracking may also cause earthquakes

  • Sandy relief bill says rebuilding effort should take into consideration climate-related risks

    The $60 billion Sandy relief bill being debated this week in the Senate does not specifically mention the words climate change or global warming, but it implicitly raises topics and themes which are part of the climate change discussion; the bill says that federal, state, and local agencies engaged in the post-Sandy rebuilding effort should take into consideration “future extreme weather events, sea level rise and coastal flooding”

  • A 1978 NY state law requiring updated emergency preparedness plans largely ignored

    In 1978, a New York state law was passed which required that annually updated plans for the restoration of vital services in the event of a major storm; in the three decades since, the law has been largely ignored due to tight budgets and politicians unwilling to prepare for a storm which may or may not hit

  • To keep global average temperature from rising above 2°C, action should be taken by 2020

    Limiting climate change to target levels will become much more difficult to achieve, and more expensive, if action is not taken soon, according to a new analysis; a new study explores technological, policy, and social changes that would need to take place in the near term in order to keep global average temperature from rising above 2°C, a target supported by more than 190 countries as a global limit to avoid dangerous climate change

  • New view of meteorite impact

    See video

    High-speed video of projectiles slamming into a bed of disks has given scientists a new microscopic picture of the way a meteorite or missile transfers the energy of its impact to sand and dirt grains; the research may change the way scientists model meteorite and missile impacts and their effects

  • Sandy exposes weaknesses of antiquated sewage systems in N.Y., N.J.

    Hurricane Sandy destroyed homes, apartments, and entire communities, and it also exposed the outdated sewage systems in New York and New Jersey; since Hurricane Sandy, millions of gallons of raw sewage have infiltrated waterways in both states, and it could take several years and billions of dollars to fix the systems; New York governor Andrew Cuomo estimated that it will cost about $1.1 billion to repair treatment plants; officials in the field say that much more will have to be done

  • Cybersecurity company using hackers own devices against them

    A California cybersecurity start-up, marketing itself as a private cyber intelligence agency, works to identify foreign attackers who are attempting to steal corporate secrets; it does so by  using the attackers’ own techniques and vulnerabilities against them; the company also collects data on hackers and tricks intruders into stealing false information

  • Expert show how to crack every common password in under six hours

    GPU computing has improved considerably in recent years, and Jeremi Gosney, founder and CEO of Stricture Consulting Group, used a 25-GPU cluster that can run through 350 billion guesses per second to show how easy it would be to crack practically any password out there (easy, that is, if you can use a 25-GPU cluster )
