After running computer simulations, European and Japanese scientists concluded that plants that haven’t been bulldozed, poisoned, burnt up, or attacked by invasive pests will continue to absorb more carbon as atmospheric carbon levels rise. But they found that rising temperatures could eventually prevent vegetation from absorbing any more of our CO2 pollution.
