  • LI-COR Analyzers Monitoring Carbon Dioxide Worldwide as Atmospheric Levels Reach 400 parts per million

    On May 13, the National Oceanic and Atmospheric Administration (NOAA) reported a preliminary daily average carbon dioxide (CO2) reading of 400.07 parts per million (ppm) at the Mauna Loa Observatory on the Big Island of Hawaii. On May 9, a reading over 400 ppm was reported at the site for the first time ever. But that reading (400.03 ppm) was later revised to 399.89 ppm. The first CO2 ...

  • Figuring out where to put the carbon

    To meet our immediate energy needs without exacerbating climate change, most experts agree, we’ll need to find a way to store the carbon dioxide given off by the combustion of coal, oil and natural gas. But no full-scale storage systems exist, and the plans to create them have many unknowns. New projects at MIT could help to fill that information gap. At the American Geophysical Union’s fall ...

  • Typhoons bury tons of carbon in the oceans

    A single typhoon in Taiwan buries as much carbon in the ocean - in the form of sediment - as all the other rains in that country all year long combined. That's the finding of an Ohio State University study published in a recent issue of the journal Geology. The study - the first ever to examine the chemistry of stream water and sediments that were being washed out to sea while a typhoon was ...


  • CSULA researchers study the effects of planting carbon underground

    Working among the pines and lakes of Mammoth Mountain, Cal State L.A. faculty and students are studying the potential impact of technologies that can slow carbon dioxide accumulation in the atmosphere by storing it underground.   The team of researchers, fueled by funding and staff support from the University’s Center for Energy and Sustainability (CEaS), are utilizing ...

  • EPA, local agencies & residents to analyze indoor air problems in basements

    The U.S. Environmental Protection Agency (EPA) will be working with residents in four Kansas counties to check potential oxygen depletion issues in the basements of their homes. Oxygen depletion can occur when carbon dioxide, methane or other soil vapors seep into building spaces, especially basements. EPA officials became concerned amid reports of carbon dioxide and methane vapors discovered in ...

  • EPA Seeks Public Comment on U.S. Greenhouse Gas Inventory

    The U.S. Environmental Protection Agency is seeking public comment on a draft report that analyzes sources of greenhouse gas emissions. The report, Inventory of U.S. Greenhouse Gas Emissions and Sinks: 1990-2005, will be open for public comment for 30 days after the Federal Register notice is published. After responding to public comments, EPA will submit, through the U.S. Department of State, ...

  • US EPA seeks public comment on greenhouse gas inventory

    The US Environmental Protection Agency is seeking public comment on a draft annual report that analyzes sources of greenhouse gas emissions. The report, Inventory of U.S. Greenhouse Gas Emissions and Sinks: 1990-2006, will be open for public comment for 30 days after the Federal Register notice is published. The major finding in this year's draft report is that overall emissions during 2006 ...

  • Science article on GHG accounting misses the mark on biofuels

    Biofuels produced from biomass feedstocks (i.e. plant matter) are, by definition, carbon neutral because carbon dioxide tailpipe emissions from the combustion of biofuels are readily absorbed by growing plants. As such, the tailpipe emissions resulting from the use of a gallon of ethanol produced from corn grown on U.S. farmland are negated by the growing of the corn itself. Yet, in a newly ...

  • Methane Levels in Air Lower Due to Leakage Control

    Despite an increase in methane-generating activities, such as drilling for fossil fuels, researchers have found that the amount of methane concentrations in the atmosphere have dropped over the past few decades, according to Climate Central. A team of atmospheric chemists have investigated and attribute this phenomenon to significantly diminished methane leakage from oil and gas wells. ...

  • Germany lowers biogas formaldehyde emissions

    The renewable energy sector has grown enormously in Germany in recent years and there are now large numbers of plants producing energy from biogas/anaerobic digestion. The emissions from these plants are regulated, but the measurement of formaldehyde (a carcinogen) is being reduced as a result of a financial incentive system. However, the measurement of formaldehyde is challenging and in order to ...
