> 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 a) "Local climate change" that is "largely caused by human activity" is not what we're talking about here. b) If something causing issues with fresh water access is enough to define it as a "health risk" then every natural or human-caused disaster in the history of the world is a "health risk" and the term is meaningless. c) If we can define any problem worldwide as a "health risk" and on that basis sue anyone who disagrees with our evaluation or recommended policy, that's a recipe to legally shut down any argument.
