> Defining climate change as a "health risk" is insane, sorry.

So far in this thread, I've been called "insane" and "out of my right mind". I really wish HN were more polite, this kind of language is toxic to having a good discussion.

Climate change is certainly a health risk. Already there have been numerous issues with fresh water access in developing countries due to local climate change that is largely caused by human activity. Lack of fresh water is a health risk. There are numerous other health risks associated with a changing climate, and it is certainly not "insane" to think that's true.
