Climate Change Causing an Increase in Poison Ivy

A few weeks ago, I wrote about finding an increase in poison ivy at Little Falls. I didn't mention that I also saw a dramatic increase of  poison ivy surrounding the petroglyphs in Tum Tum, Washington. And of course, not to mention the plants growing at Drummheller Spring. It was strange to imagine why this plant is increasing so much. 

Then I found an article that blames climate change for the increase. In experiments, exposing poison ivy to increased carbon dioxide results in significant growth. This makes me wonder about the growth I have witnessed this year. Check out the article here
