  • Wildfires Spew Carbon Emissions Into the Atmosphere

    BOULDER, Colorado, November 1, 2007 (ENS) - Severe wildfires can contribute as much as vehicles to carbon emissions in some U.S. states, although the amount is highly variable, according to a study based on satellite data. New research published in the journal 'Carbon Balance and Management' quantifies these emissions and suggests fires will complicate emissions monitoring and modelling efforts. ...

  • Landfill Methane Emission Monitoring

    Methane (CH4) plays a critical role in the radiation balance and chemistry of the atmosphere. The major anthropogenic sources are anaerobic production from landfills, ruminant animals and their waste, release from the mining and use of fossil fuel, burning of biomass, etc.. On average, over the global scale, landfill methane emissions contribute between 10-19% of the anthropogenic methane burden ...

  • Monitoring is key to cutting emissions

    The big achievement of the Paris Agreement on climate change last December was getting more than 190 countries around the world to agree to a significant programme of lowering carbon emissions. But the reality is that promises are no good if not followed up by action. Nations also pledged to pursue various other policies aimed at ...

  • Monitoring methane emissions from agriculture and dairy farming

    Methane (CH4) is the second most prevalent greenhouse gas emitted from human activities. In 2014, CH4 was responsible for around 11 percent of all US greenhouse gas emissions caused by human actions. Methane is emitted by a range of natural sources such as marshlands, leakage from natural gas systems and livestock farming [1]. Domestic ...

  • Understanding the movement of mercury in the atmosphere

    In order to reduce mercury pollution, we need to understand its movement in the global atmosphere. A UN report summarises current information on mercury transport in the atmosphere and indicates that intensive global monitoring is needed to inform and evaluate policy. As a result of EU policy1, European emissions of mercury have dropped considerably in recent decades, decreasing by about 60 per ...

  • Monitoring Gas Emissions from Volcanoes to Predict Volcanic Activity

    To understand and predict the behaviour of volcanoes an increasing number of scientists are combining geological monitoring and geochemical models. By measuring and monitoring the prevalence of gases like CO2, scientists hope to be able to better predict the likelihood of volcanic eruptions. ...

  • “21st Century Challenges for Long-Term Monitoring” draws atmospheric scientists from around the world

    More than 250 people attended ESRL’s Global Monitoring Annual Conference in May, presenting dozens of talks and posters on atmospheric trends and analyses, many of them derived from ESRL-collected data. For three days, researchers from 19 countries discussed regional emissions of greenhouse gases, how best to interpret data showing a rise in global methane levels, and the dynamics and speed of ...

  • Earth Networks Teams with State of California and Leading Atmospheric Researchers to Deploy Advanced Greenhouse Gas Monitoring Network

    Earth NetworksSM, the operator of the largest weather, lightning and climate observation networks and owner of WeatherBug®, announces its collaboration with the State of California and leading atmospheric scientists from ...

  • 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 ...

  • EU project taking CO2 out of the atmosphere

    'The European Commission is committed to encouraging industry to reduce its carbon dioxide (CO2) emissions and research plays a vital role in that,' said the European Science and Research Commissioner, Janez Potočnik. The accumulation of CO2 is considered to be the main cause of climate change. However, the EU-backed project CO2SINK, with financing to the tune of EUR 8.7 million, aims to ...

  • Tourist cruise ships increase atmospheric pollution in the Arctic

    Levels of air pollution significantly increase on the island of Svalbard in the Norwegian Arctic when tourist cruise ships are present, according to a recent study. With shipping levels rising in the region, the researchers recommend that stricter emissions regulations are introduced in order to limit the impact of pollution on the Arctic environment. Ship traffic is a major source of ...

  • Diesel Emissions, Health and the Law

    When diesel is used as an engine fuel, it is inevitable that you will produce Products of Incomplete Combustion (PICs). Hence, we never just produce carbon dioxide (CO2) and water (H2O) alone, but rather a myriad of hydrocarbons including aromatics (e.g. benzene, toluene) aldehydes and poly-aromatic hydrocarbons (PAHs) in a semi-volatile phase or bound with carbonaceous particulate, and ...

  • Calculating emissions from shipping

    Shipping is a significant source of atmospheric pollutants, which contribute to climate change and have negative effects on human health and the environment. A new study has applied detailed methods to estimate global fuel consumption from international shipping, including for the first time, an estimation of emissions from the global fleet while in port. Developing appropriate policies to ...

  • Closing the emissions gap with peatlands

    Wetlands International urges action to mitigate CO2 emissions from peatlands, as thousands of delegates flock to the Middle East to negotiate global policies on climate change. Peatland restoration and conservation action, stimulated by UNFCCC incentives, could significantly contribute to closing the so-called “emissions gap”. The annual conference of the Parties to the United ...

  • Measuring Greenhouse Gas Emissions

    Recent reports on the measurement of greenhouse gas emissions have shown that CO2 levels within the atmosphere are steadily rising. The UN has consistently promoted the use of renewable energies for the control of atmospheric conditions. These need to be steadily monitored and in order to do so it is essential that cheap, robust, and accurate sensors ...

  • A new global map of ammonia emissions

    For the first time, a global map of atmospheric ammonia emissions has been produced using satellite measurements. This opens up new ways to survey air quality and monitor the Earth's atmospheric chemistry from space. Modern agricultural practices, especially intensive farming methods and widespread fertiliser use, are mainly responsible for ammonia emissions, which have more than doubled since ...

  • Emission sources identified in Huon Study

    Emissions from domestic wood-fired heaters in southern Tasmania's Huon Valley dwarf emissions from forest regeneration burns, according to a new CSIRO study. "Smoke plume events from prescribed burns do impact the air quality and occasionally exceed the 24-hour standard concentration for particulates but wood-fired heater emissions lead to particulate concentrations that are seven ...

  • Speakers announced for international emissions conference

    The organisers of CEM 2014 have published the titles of the Conference presentations that will take place from 14th to 16th May at the Renaissance Polat Istanbul Hotel in Turkey. The selected presentations will be given by speakers from 13 different countries covering a wide variety of subjects within the event’s emissions monitoring theme. The control of emissions to air can only be ...
