on NPR: Poison ivy thriving with climate change and CO2
Elevated CO2 in Duke’s Free-Air CO2 Experiment (FACE) stimulated growth of woody plants, but none like poison ivy. Not only did it grow fast; it also increased toxicity. The interview includes PhD student Jackie Mohan and collaborator William Schlesinger on our studies of poison ivy growth in response to high CO2. The study showing this effect is here:
