William Connolley stumbles into the minefield that is defining the Australian drought:
Australia hasn’t got a mega-drought, only a 10-15% reduction in rainfall.
Many commenters complain, mostly offering up the absolutely useless evidence offered by alarmist news stories from the Australian press. Lab Lemming nails it by noting that drought is best defined by societal impact, not raw measures of precipitation falling from the sky.
By that measure, the lack of precipitation and warmer temperatures is colliding with a growing population and agricultural industry. But by any measure, it’s been darn dry over the last six years or so.
