Hmmm.  "Kids Suing For the Environment" ?   Or, "Kids, Manipulated into Shills to Sue for Environmentalist Organizations"?  

But, perhaps a court case would be educational.  One of the first things to be pointed out surely would be the fact that, if the United States just disappeared tomorrow as if it never had existed, fully 3/4 of the "catastrophic climate problem" would still be here!  There is no practical, tangible effect our government policies could have on the climate system, acting in isolation - even if it did oblige us all to go back to a Neolithic standard of living and eat grass.  :-/
