We’re literally doomed

At least I now have confirmation that allergies really *are* getting worse and I’m not just getting more whiny over time lol

Same goes for the toxins in poison ivy, poison oak, and related species. Increased CO2 correlates to more concentrated urushiol and bigger leaves.

Also more luxuriant growth for poison ivy:

Already poison ivy’s growth and potency has doubled since the 1960s, and it could double again once CO2 levels reach the 560 ppm mark, Mr. Ziska said. As a result, Americans might have to scratch their way into a climate-altered future.

“The chemistry of the oil itself changes in such a way that it more likely will produce a rash when you come in contact with it,” he said. “In the last 50 years, the growth rate of poison ivy plant already has doubled, increasing the risk of being exposed to urushiol.”
