According to a recent study published in Proceedings of the National Academy of Sciences, scientists reported that increasing carbon dioxide levels in the atmosphere are expected to foster an environment conducive to widespread poison ivy growth by the year 2050. A leading scientific expert predicts that under atmospheric carbon dioxide concentrations the planet will likely reach by the middle of this century, poison ivy will grow faster, bigger, and more poisonous.
