text: Another new study, detailed in the Nov. 1 issue of the journal Nature, found that over the past 60 years, forest fires have had the greatest direct impact on carbon emissions from the boreal forests located in the higher latitudes of Canada, Alaska and Siberia, both by the amount of carbon released as the forests burn and the emission of carbon dioxide from the soil as the sun reaches through the empty branches and promotes faster decomposition.
