Winds blow away carbon dioxide, but deserts trap it, study finds.
The study used GIS technology to look at how wind affects the amount of carbon dioxide in the air over Iraq. They found that higher wind speeds tend to lower the concentration of carbon dioxide, while lower wind speeds increase it. In the spring, even though the western region had strong winds, the carbon dioxide levels were still high due to human activities and lack of vegetation. The movement of wind helps spread carbon dioxide away from its source, mixing it with fresh air and reducing its concentration.
