Comments regarding "Poison Ivy to get Itchier with Global Warming".
 Poison Ivy to get Itchier with Global Warming Message #20
News reports this morning are indicating that poison ivy vines will grow faster and bigger as the levels of carbon dioxide in the atmosphere rise. In fact, studies have shown the poison ivy vine can grow 3 times larger!

Vines that grow with an increase in carbon dioxide levels also produce more of its rash-causing chemical, urushiol.  Urushiol can cause an itchy blistering rash on hikers when they come in contact with the leaves of a poison ivy plant.

Details of the study can be found in this week's Proceedings of the National Academy of Sciences.
