Poison
Ivy and CO2!
According to the Wall Street Journal, research published in Weed Science (is your subscription up to date?) indicates that poison ivy has gotten MUCH nastier since the 1950's. Leaf size and nasty oil content are way up.
So it is not your imagination that it is worse than when you or your parents were kids. Seems like a minor problem, all in all, considering the possible consequences of a 33% increase in CO2 in only 50 years. Since poison ivy absorbs more than its share of CO2, it is helping combat climate change. So there IS something to love about this plant.
By the way, every so often someone threatens me for talking about climate change, which they claim is a liberal hoax. So here's the deal: Every time somebody threatens me, I will increase the amount of information about climate change on this website. So go right ahead and hassle me. Make my day.
Recently, I got a few climate-change deniers hassling me, so as promised, I am adding more info about climate change every time they act up: The planet just passed above the 400 parts per-million number. It was 280 ppm before people starting burning fossil fuel. And we can't rely on poison ivy to absorb all that excess CO2. |
