Global warming = more kidney stones?
That's what this article at NewScientist.com is saying.
OK, strictly speaking, it's saying that global warming = more cases of dehydration, with dehydration being a known cause of kidney stones. But even as a lay person, I've got a problem with this claim, that being this: Even if overall global temps are going up, that doesn't mean they'll necessarily increase significantly enough to cause increased numbers of dehydration cases sufficient to cause the kind of increase in kidney-stone incidence that the writers are claiming (an additional 2.5 million cases per year).
But I could be wrong. What do you think?
