  • 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 ...

  • 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 ...

  • 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 ...

  • 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 ...

  • 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, ...

  • Santa Claus is Chinese -- Or -- Why China is Rising and the United States is Declining

    **Last year at this time, we released an Update entitled 'Santa Claus is Chinese,' which generated a lot of interest. Since little has changed, we thought you might like to see it again during this holiday season. I know Santa Claus is Chinese because each Christmas morning after all the gifts are unwrapped and things settle down I systematically go through the presents to see where they are ...
