"Rising Temperatures Set the Stage for Poison Ivy's Success"

Poison ivy is expected to thrive in a warming world due to rising temperatures and increased carbon dioxide levels, growing faster and becoming more toxic. Researchers have found that poison ivy grows 70% faster with higher carbon dioxide levels and produces a more potent form of urushiol, the substance that causes the itchy rash. The plant's growth is likely due to its ability to invest energy into length rather than building thick trunks or branches. Observations from conservationists and doctors suggest an increase in poison ivy rashes, potentially exacerbated by the pandemic pushing people outdoors. The implications for human health are concerning, and precautions should be taken to avoid contact with poison ivy.
