Scientists from the University of Wisconsin-Madison and the University of Minnesota at Morris have found that increased levels of atmospheric carbon dioxide have led to the rapid growth of certain tree species. The quaking aspen, a popular North America deciduous tree, has seen a 50 percent acceleration in growth over the past 50 years due to increased CO2 levels.
Trees are necessary climate regulators since they process carbon dioxide and give off oxygen. Humans process oxygen and give off carbon dioxide, working harmoniously with natural plant life to maintain proper atmospheric composition. Since natural forests represent about 30 percent of the earth’s surface, they are highly effective at segregating greenhouse gases.
The quaking aspen is a vibrant, dominant tree found in both Canada and the United States. It is considered to be a “foundation species”, meaning that it helps dictate the dynamics of the plant and animal communities that surround it. Roughly 42 million acres in Canada and 6.5 million acres in Wisconsin and Minnesota are composed of aspen trees.
