  • US introduces new mandatory measurement and reporting of greenhouse gases

    Tough new EPA rules mean vehicle and engine manufacturers will be required to measure and report CH4 and N2O emissions from model year 2011. In April 2009 the US EPA proposed a new mandatory greenhouse gas reporting program. Although the sheer volume of CO2 in the atmosphere means that it is by far the biggest contributor to the greenhouse effect, there are other gases that also have a measurable ...

  • Trapped atmospheric waves triggered more weather extremes

    Weather extremes in the summer - such as the record heat wave in the United States that hit corn farmers and worsened wildfires in 2012 - have reached an exceptional number in the last ten years. Man-made global warming can explain a gradual increase in periods of severe heat, but the observed change in the magnitude and duration of some events is not so easily explained. It has been linked to a ...

  • Dependable detection of refrigerant gases with Crowcon’s F-Gas Detector

    Fluorinated (Freon) gases, which include hydrofluorocarbons (HFCs), perfluorocarbons (PFCs), hydro-chlorofluorocarbons (HCFCs) and sulphur hexafluoride (SF6), are a family of man-made chemicals containing fluorine. These ’F-gases’ are extremely powerful greenhouse gases that trap heat in the atmosphere, contributing to global warming – most are between 1,000 and 20,000 times ...

  • Greenhouse Gas Concentrations Reach New Record

    The amount of greenhouse gases in the atmosphere reached a new record high in 2011, according to the World Meteorological Organization. Between 1990 and 2011 there was a 30% increase in radiative forcing – the warming effect on our climate – because of carbon dioxide (CO2) and other heat-trapping long-lived gases. Since the start of the industrial era in 1750, about 375 billion tonnes ...

  • Record greenhouse gas levels: see for yourself

    For the first time, greenhouse gas data are accessed easily on a new CSIRO website.

  • Semiconductor and aluminium industries underestimate greenhouse gas emissions

    Emissions of the greenhouse gases (GHGs) tetrafluoromethane (TFM) and hexafluoroethane (HFE) reported by industry accounted for only around half actual levels measured in the atmosphere between 2002 and 2010, new research reveals. The semiconductor and aluminium production industries, the two main sources of these gases, have reported success in their voluntary efforts to control these emissions. ...

  • Greenhouse gas concentrations hit yet another record

    The amount of greenhouse gases in the atmosphere reached yet another new record high in 2014, continuing a relentless rise which is fuelling climate change and will make the planet more dangerous and inhospitable for future generations. The World Meteorological Organization’s Greenhouse Gas Bulletin says that between 1990 and ...

  • New greenhouse gas identified, say MIT scientists

    A gas used for fumigation has the potential to contribute significantly to future greenhouse warming, but because its production has not yet reached high levels there is still time to nip this potential contributor in the bud, according to an international team of researchers. Scientists at MIT, the Scripps Institution of Oceanography in San Diego and other institutions are reporting the results ...

  • Greenhouse Gas CO2 Sidetracked in Oceans` Twilight Zone

    WOODS HOLE, Massachusetts (ENS) - Climate experts have relied on the oceans to absorb enough of the greenhouse gas carbon dioxide to slow global warming, but new research by an international team of scientists shows that the oceans may have little impact on changes in the atmosphere or climate. The research indicates that instead of sinking, carbon dioxide is often consumed by ...

  • US asks for comments on planned greenhouse gas law

    The public will have an opportunity to comment before the US Environmental Protection Agency takes any action to regulate the greenhouse gases responsible for climate change, EPA chief Stephen Johnson told members of Congress in a letter last Thursday. Johnson said he will solicit public input through an Advance Notice of Proposed Rulemaking as the agency considers the specific effects of climate ...

  • Growth of Global Greenhouse Gas Emissions Accelerating

    CANBERRA, Australia, (ENS) - Global emissions of the greenhouse gas carbon dioxide have more than doubled since 1990 and the rate of increase is accelerating, according to new information gathered and analyzed by the Australian government research service. The scientists say this trend, based on data collected over the past 30 years, indicates that recent efforts to ...

  • Greenhouse Gas Concentrations in Atmosphere Reach New Record

    The amount of greenhouse gases in the atmosphere reached a new record high in 2012, continuing an upward and accelerating trend which is driving climate change and will shape the future of our planet for hundreds and thousands of years. The World Meteorological Organization’s annual Greenhouse Gas Bulletin shows that between 1990 and 2012 there was a 32% increase in radiative ...
