What was the role of warmists in the Queensland flood disaster?

Australia was told to prepare for droughts as a result of climate change, and let its guard against flooding, writes Christopher Booker (Telegraph)
"Ever more alarming facts are emerging to show how Brisbane’s floods were made infinitely worse by cockeyed decisions inspired by the obsession of the Australian authorities with global warming. Inevitably, the country’s warmist lobby has been voluble in claiming that such a “freak weather event” (as the BBC called it) is a consequence of man-made climate change. But far from being an unprecedented “freak event”, the latest flood was nearly a foot below the level of one in 1974 and 10 feet below the record set in 1893. "
