GHG be­hind low rain in Aus­tralia

Down to Earth - - SCIENCE -

SOUTH-WESTERN parts of Aus­tralia have been fac­ing a de­cline in rain­fall dur­ing au­tumn and win­ter months since the 1980s. Rea­sons for this are an­thro­pogenic, says a new model. The model used data recorded dur­ing 19812012 to study if the im­pact could have been caused by hu­man-made or nat­u­ral fac­tors. It con­cluded that green house gas emis­sions and ozone de­ple­tion are the main cul­prits. Na­ture Geo­science, July 2014
