The higher CO2 levels that inherently come with global warming are actually a good thing if you're starving in a third world country. Plants breathe CO2, and higher levels means faster plant growth and higher crop yields.
But that isn't the story you want to paint if you're a big media operation like USA Today. Instead, you want to frame it like this:
Study: Global warming boosts poison ivy
WASHINGTON (AP) — Another reason to worry about global warming: more and itchier poison ivy. The noxious vine grows faster and bigger as carbon dioxide levels in the atmosphere rise, researchers report Monday... Compared to poison ivy grown in usual atmospheric conditions, those exposed to the extra-high carbon dioxide grew about three times larger — and produced more allergenic form of urushiol, scientists from Duke and Harvard University reported. "...the shift toward a more allergenic form of urushiol have important implications for the future health of both humans and forests," the study concludes.
There you have it. That means I can expect to get stricken with poison ivy three times more than I have in the past, which is currently a consistent zero times. This coupled with inch higher water must be part of the end of civilization that Al Gore anticipates. Remember, folks, all of this global warming nonsense you're reading about is just part of the 2008 Democratic platform as delivered by big media.
