Trees are 20% to 30% bigger than they used to be.
While exposure to high levels of carbon dioxide can have ill effects on natural systems and infrastructure, trees have no issue gluttoning themselves on Earth's extra supply of the greenhouse gas.
Although such growth may not be noticeable to the average person, compared to the trees of 30 years ago, modern vegetation is about 20% to 30% bigger than it used to be.
Overall, Sohngen said this work shows that the wood volume response to carbon dioxide in our ecosystem is even higher than his colleagues predicted with experimental studies.
