This, the fourth post in our water security series, began as a response to the first of them, the Townsville Water Discussion Paper, and addresses an issue which none of the first three looked at. Parts 2 and 3 are here and here. This is a guest post by Malcolm Tattersall. Once again, views expressed are the author’s, not those of NQCC.
When I read Gail Hamilton’s post six weeks ago I agreed with nearly all of it but noticed a gap which was potentially important, i.e. the impact of climate change on our water security: the ‘Regional Water Supply Security Assessment’ from the Department of Water and Energy Supply (2014) (pdf here), upon which she relied for her ‘current situation’ section, didn’t consider climate change effects at all.
That seemed quite odd to me since we know that climate change is with us already on a global level – that most of the hottest years on record have occurred this century, that desertification is a key driver of conflicts in the Middle East, and that sea level rise is drowning low-lying islands and threatening major cities around the world. Some of us have also been feeling, on a much more local and personal level, that Townsville has been having weaker Wet seasons and hotter summers than ever before, and I happened to know, because I looked at it recently, that Bureau of Meteorology (BoM) data backs up our feelings.
