Global warming causes kidney stones

SciAm magazine reports:

Add kidney stones to the growing list of possible consequences of global warming. A new study warns that as many as 2.3 million more people may develop these mineral deposits in their kidneys by the year 2050 as the result of a warming world. The reason? There's a greater risk that they will be subject to dehydration in more sultry climes, which is believed to be a major contributor to stone formation, according to research published this week in Proceedings of the National Academy of Sciences USA.

They are really getting desperate to find scare stories about global warming. It is more likely that people will drink a little extra water, if they get too hot.
