The increase in forest fires can now be seen as a factor which contributes to global warming. Trees, in the carbon cycle, are labeled a “sink” or a store for carbon. The ability of trees to store carbon dioxide has helped to reduce the amount of CO2 that is pumped into the atmosphere. But now that more trees are being burned through increased forest fires, this stored carbon is being released and the CO2 becomes part of the greenhouse gases that drive the greenhouse effects. So, we believe that extra fires intensify global warming. Furthermore, carbon is released in the decomposition of the trees after the fires. There is no doubt that global warming and forest fires are linked to rising temperatures. Which of the following is closest in meaning to word “decomposition ” in the paragraph?
