  • Emissions, Concentrations, & Temperature: A Time Series Analysis

    Abstract  We use recent advances in time series econometrics to estimate the relation among emissions of CO2 and CH4, the concentration of these gases, and global surface temperature. These models are estimated and specified to answer two questions; (1) does human activity affect global surface temperature and; (2) does global surface temperature affect the atmospheric concentration of ...

  • Remote sensing of particular pollution from space: Have we reached the promised land?

    The recent literature on satellite remote sensing of air quality is reviewed. 2009 is the 50th anniversary of the first satellite atmospheric observations. For the first 40 of those years, atmospheric composition measurements, meteorology, and atmospheric structure and dynamics dominated the missions launched. Since 1995, 42 instruments relevant to air quality measurements have been put into ...

  • A statistical model for predicting carbon monoxide levels

    This paper presents a statistical model that is able to predict carbon monoxide (CO) concentrations as a function of meteorological conditions and various air quality parameters. The experimental work was conducted in an urban atmosphere, where the emissions from cars are prevalent. A mobile air pollution monitoring laboratory was used to collect data, which were divided into two groups: a ...

  • Polish gas from Polish coal: environmental benefits

    The development of coalbed methane gas from Polish coal offers a significant opportunity to reduce noxious pollutant emissions associated with coal combustion. A review of energy supply and consumption within Poland, and of available coalbed methane resources, indicates that use of coalbed methane could eliminate 40-60 million tonnes of sulfur dioxide and particulates from the atmosphere, save ...

  • 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 ...

  • Least-Cost Approaches to Reducing Acid Emissions

    ' The costs of meeting sulfur emission targets can be high. It is essential, therefore, that countries adopt policies which (a) minimize the net economic and social costs of reducing emissions to the agreed target levels, and (b) maximize the overlap between measures designed to reduce acidifying emissions and those addressing other forms of air pollution. This note discusses alternative ...

The discussants’ comments are organized beginning with a note on the history of satellite sensing, followed with a brief discussion of the strengths and weaknesses of satellite observations relative to air quality management needs. ...

  • Innovative wet electrostatic precipitators assure competitive edge in acid marketplace

    The unsteady global economic recovery continues to subject many core industries to persistent volatility in profits, prices, markets and capital investments. However, some analysts remain optimistic about the global international trade in sulfur in all forms, particularly sulfuric acid. This versatile mineral acid is both the world’s most widely used chemical, and the one with the highest ...

  • Climate Change Initiatives are Heating Up in the United States

    If you thought the reporting of greenhouse gas (GHG) emissions would not affect you, think again! The climate change issue is heating up in the United States even though we are not a party to the Kyoto Protocol. With the number of extreme weather events tripling in the past 50 years, the global average level of the sea increasing, and the amount of snow cover declining,1 U.S. citizens want to ...
