So, when I first learned about global warming in 3rd grade or so, I figured it just meant that everywhere on Earth would get a little hotter. That was bad enough, since I grew up in the southeastern US where summers were already hot enough to make the backs of your hands sweat, and snow was a rare treat.
Of course, it’s not that simple–”Global Warming” got renamed ‘Global Climate Change” for a reason. Rising sea levels, coral reef bleaching, droughts, unusually cold winter storms, bizarre urban tornadoes–there’s a whole cornucopia of ripple effects, many of which are obvious in hindsight, but weren’t at the top of the common-sense list of things global climate change might do.
Now we can add healthier, itchier poison ivy to the shit list:
…carbon dioxide is, basically, plant food. I’m told that rising levels of CO2 in the atmosphere affect different plants in different ways, but poison ivy is definitely one of the winners of global warming. For this unpleasant little weed, more CO2 seems to mean more growth.
…not only is poison ivy growing fat and happy on the spoils of our carbon emissions, but that plants getting more CO2 also produce more, and stronger, levels of urushiol—the toxin that makes the ivy so darned appealing to begin with.
All I have to add is: That fucking sucks.
