Poison ivy to bloom, become more toxic, thanks to global warming

Poison ivy, a noxious plant often found in North America, and parts of Asia, could become more common place as global warming creates an environment conducive to its growth.

Poison ivy is poised to be one of the big winners in this global, human-caused phenomenon. Scientists expect the dreaded three-leafed vine will take full advantage of warmer temperatures and rising levels of carbon dioxide in the atmosphere to grow faster and bigger — and become even more toxic.
