it's interesting, but as the article said itself, it's pretty far fetched.    but I think it does good in the way that it shows how little we really do know.
i think we all know that we can't predict anything involving weather or climate.   and i also think that we are to stupid to think proactivly instead of reactivly, but hey - our planet is overpopulated anyways.   is it really that bad if millions die?
