Because, apparently, Australia would be subject to increasing global warming drought, damming projects in Queensland were shelved and desalination plants built instead (now mothballed). This is a matter of record and a source of anger for many residents there. Also, it's not a great idea to build on flood plains. However, the usual suspects are claiming this one for ‘catastrophic climate change’ and, as is usual, their grasp of history is about as firm as chocolate pliers.
17th January: Highest flood on record, occurred at Brisbane and Ipswich.
10th January: Heavy floods at Ipswich.
17th December: Flood at Ipswich.
11th April: Heavy floods at Brisbane and Ipswich.
19th and 20th May: Great floods at Ipswich and Brisbane; river at Ipswich rose 45 feet, and at Brisbane 12 feet.
The above is just a small sample. If you go and check here at 'Queensland Flood History' you’ll discover enough to boggle the mind. This has fuck all to do with ‘catastrophic climate change’.
