Southeast Queensland Climate Change Assessment
Southeast Queensland water supply system
Applied a new procedure to assess the impacts of climate change on rainfall and streamflow in Southeast Queensland, identifying a marked increase in maximum daily temperatures since 1980 alongside significant declines in rainfall and streamflow, concluding that water-supply yield estimates based solely on historical climate conditions are likely significantly over-estimated.
