Environmental Context. Excessive levels of carbon dioxide are accumulating in the atmosphere, principally from burning fossil fuels. The gas is linked to the enhanced greenhouse effect and climate change, and is thus monitored carefully, along with other trace gases that reflect human activity.The rate of growth of carbon dioxide has increased gradually over the past century, and more rapidly in the last decade. Teasing out fossil emissions from changes due to wildfires and to natural exchange with plants and oceans guide global attempts in reducing emissions.
