  • Albedo Enhancement by Stratospheric Sulfur Injections: A Contribution to Resolve a Policy Dilemma?

    Fossil fuel burning releases about 25 Pg of CO2 per year into the atmosphere, which leads to global warming (Prentice et al., 2001). However, it also emits 55 Tg S as SO2 per year (Stern, 2005), about half of which is converted to sub-micrometer size sulfate particles, the remainder being dry deposited. Recent research has shown that the warming of earth by the increasing concentrations of CO2 ...

  • Atmospheric research at Ny-Ålesund

    NILU’s atmospheric research in Ny-Ålesund serves three main purposes: Characterisation of the clean atmosphere and atmospheric changes. Investigations of atmospheric transport of pollutants into the Arctic. Studies of atmospheric processes and phenomena in the Arctic.  The Arctic is an interesting area for observations relevant to the cycling of carbon dioxide and other gases which are of concern ...

  • Geoengineering: Encouraging Research and Overseeing Implementation

    Ideas on how to engineer Earth’s climate, or to modify the environment on large scales to counter human impacts, do not enjoy broad support from scientists. Refereed publications that deal with such ideas are not numerous nor are they cited widely. Paul Crutzen (2006) analyzes the idea of intentionally injecting sulfur into the stratosphere, to enhance the albedo of Earth, so as to slow the ...

  • Environmental policy issues related to atmospheric change

    Four main environmental issues are linked to the chemical changes in the atmosphere: air quality, deposition, climate change, UV radiation and stratospheric ...

  • Geo-Engineering to Confine Climate Change: Is it at all Feasible?

    Paul Crutzen (2006) has suggested a research initiative to consider whether itwould be feasible to artificially enhance the albedo of the planet Earth to counteract greenhouse warming. The enhancement of albedo would be achieved by intentionally injecting sulfur into the stratosphere. The rational for proposing the experiment is the observed cooling of the atmosphere following the recent major ...

  • How to reverse the causes of ozone layer destruction

    Since the causes of ozone layer depletion were identified, solutions were put into place to reduce or eliminate their usage. The U.S. Clean Air Act and the Montreal Protocols address the problem internationally. The goal of these treaties is to stop the damage to the ozone layer by phasing out known contributors.Although there are numerous causes of ozone layer depletion, chloroflurocarbons have ...

  • The Norwegian Troll station in the Antarctic opened

    The framework conditions for Norwegian research in Antarctica are completely changed. Queen Sonja opened the Norwegian summer station, Troll, on 12 February 2005 for year-round operations. NILU will participate in the research at Troll covering e.g. greenhouse gases, UV radiation, ozone and various air ...

  • TransCom N2O model inter-comparison – Part 1: Assessing the influence of transport and surface fluxes on tropospheric N2O variability

    We present a comparison of chemistry-transport models (TransCom-N2O) to examine the importance of atmospheric transport and surface fluxes on the variability of N2O mixing ratios in the troposphere. Six different models and two model variants participated in the inter-comparison and simulations were made for the period 2006 to 2009. In addition to N2O, simulations of CFC-12 and SF6 were made by a ...

  • The US Clean Air Act: Improving air quality and tracking greenhouse gas emissions?

    The US Clean Air Act is a federal law designed to reduce air pollution in order to improve the nation’s overall air quality. The intent of the federal law is to identify and reduce harmful substances that weaken the stratospheric ozone layer and continue to contribute to global climate change.Many of these pollutants, refrigerant gases, or Greenhouse Gases (GHGs) can be found within companies, ...

  • Nilu - A centre for air pollution studies in Europe

    NILU’s strong position in atmospheric European air research originated with studies of long range transport of air pollutants and acid rain in the 1970’s. This involvement is continued in the European Monitoring and Evaluation Programme (EMEP) established in 1977, in which NILU has a central position as the Chemical Co-ordinating ...

  • Caribbean volcano erupts and pollutes atmosphere

    The Soufriere Hills Volcano on Montserrat Island in the Caribbean erupted in the early morning hours of May 20, 2006. The eruption sent the following days a cloud of ash and volcanic gas nearly 17 kilometers (55,000 feet) into the atmosphere. Flying on NASA’s Aqua satellite, the Atmospheric Infrared Sounder (AIRS) tracked the cloud as it drifted west over the Caribbean Sea and Central America. ...

    Atmospheric chemist Susan Solomon finds hope in past environmental challenges. Written by Jennifer Chu, MIT News Office. You can read the original story in MIT News ...

  • Non-Ionising Radiation

    Pressures on the environment may occur through chemical, physical and biological agents. The subject of this study is physical agents, where physical fields are examined. Physical fields are part of the natural environment. Depending upon their properties and the surrounding conditions, physical fields are transmitted through the spaces in which we live, potentially affecting human health and ...

  • Benefits of the CFC Phaseout

    Benefits of the CFC Phaseout The CFC phaseout is already producing benefits for the environment, businesses, and individuals. This fact sheet explains some of these benefits. Several case studies of successful conversions to alternatives are listed also. Protection of the Ozone LayerThe chlorofluorocarbon (CFC) production phaseout is an important turning point in ...
