Forests can store more carbon emissions
A latest study showed that the role of forests as carbon dioxide (CO2) stores was much bigger than previously thought.
The findings were published in the latest issue of the journal "Science" on Thursday.
From 1990 to 2007, 8.8 billion tonnes of carbon dioxide (CO2) were released in the world through the use of fossil fuels, but around one third of them were absorbed by forests, according to the study.
The woods are responsible for the entire terrestrial storage of CO2 while agricultural land, grassland and tundra played no role at the global level as CO2 are absorbed as much as they emit, said one of the authors, Anatoly Shvidenko, from the International Institute for Applied Systems Analysis (IIASA) in Laxenburg near Vienna.
The conclusion was made after analysing the relationship between the area change of the forests and green fields and the content change of carbon dioxide in the atmosphere.
The important role of forests as a global "vacuum cleaner" of climate-damaging greenhouse gas CO2 has long been clear but the new data have proved their higher importance as terrestrial CO2-sink, the IIASA said.
Figures showed that the still not destroyed tropical rain forests are responsible for the inclusion of more than 1 billion tons of carbon per year.
The boreal coniferous forest in northern zones, primarily in Canada and Russia, swallows some 500 million tonnes per year, while the forests in the temperate zones stores annually around 780 million tonnes of carbon.
