So far there aren't observational studies on the topic. With climate change already starting to affect global weather and atmospheric conditions and carbon dioxide levels in the atmosphere rising, both Schlesinger and Mohan think it's plausible that poison ivy is changing. Plus, she said, the artificially warmer soil seems to enhance a fungus that thrives in warm soil and helps poison ivy grow. They don't need to build thick trunks or branches. Mohan said one reason for this growth is likely because, unlike shrubs and trees, vines can invest just about all their energy into length. "Poison ivy takes off more than any tree species, more than any shrub species." "My heavens to Betsy, it's taking off," she said. Poison ivy appears to love the warmer conditions. The idea is to simulate the effect of climate change and measure how plants respond. More recently, Mohan has been working on an ongoing study in the Harvard Forest in central Massachusetts, where researchers are artificially warming the top layer of soil by about 9 degrees Fahrenheit. In another experiment, Mohan found the vine's leaves grew larger with more carbon dioxide. "But we don't know why," said Jacqueline Mohan, a professor at the University of Georgia's Odum School of Ecology, who was involved in the study. Climate Cut emissions quickly to save lives, scientists warn in a new U.N.
