  • Climate models may be overestimating the cooling effect of wildfire aerosols

    Original story at MIT News Whether intentionally set to consume agricultural waste or naturally ignited in forests or peatlands, open-burning fires impact the global climate system in two ways which, to some extent, cancel each other out. On one hand, they generate a significant fraction of ...

  • Forest fires increase mercury emissions

    Mercury is a global pollutant arising from many sources, including biomass burning (BMB), which includes both wildfires and intentional fires to clear land. A recent study estimates that mercury emissions from BMB make up 8 per cent of total global mercury emissions. Mercury emissions from BMB have received growing attention. Forests in particular act as mercury sinks because atmospheric mercury ...

  • 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. ...

  • Are emissions fueling Australian droughts?

    American scientists have just confirmed that parts of Australia are being slowly parched because of greenhouse gas emissions – which means that the long-term decline in rainfall over south and south-west Australia is a consequence of fossil fuel burning and depletion of the ozone layer by human activity. Such a finding is significant for two reasons. One remains contentious: it is one thing ...

  • EU nations agree on stricter emissions testing for diesel

    European Union nations have reached a tentative deal on tougher emissions tests for diesel cars after the Volkswagen scandal showed previous methods were ineffective. The slow phase-in of the new standards, however, drew fire from environmentalists. Emissions from cars on the road in the EU have been found to be four to five times above the official limits. That's largely because the current ...
