There are a lot of interesting things to discuss in the Murray-Darling basin, the water market and associated system of dams and waterways is one of Australia's subtle-but-serious national achievements.

However the article is a puff piece and is at best alluding vaguely to those more interesting issues. It is only inspiring discussion of them as people are trying to find lenses to interpret it that aren't climate related. It'd be lovely if HN suddenly decided to take a deep interest in irrigation systems but I'll wait for a few more articles on the subject to hit the front page before I start believing it. The comment threads look more like we are playing a game of finding links that aren't climate related.
