Increased CO2 From Climate Change Will Make Faster Growing, More Potent Poison Ivy...

SCIENTISTS had some sobering news last week about the potential impact of climate change, and it didn't come from the foot of a shrinking glacier in Alaska or the shores of a tropical resort where the rising ocean is threatening the beachfront bar.

It came from a North Carolina forest, at an experimental plot where scientists can precisely control the concentration of carbon dioxide in the air. Duke researchers discovered that when exposed to higher levels of CO2, the greenhouse gas released in ever-increasing quantities from human activity, poison ivy goes haywire.
