"Over the past decade, southern Australia has suffered numerous extreme weather
and climate events, such as record-breaking heatwaves, bushfires, two major
droughts and even flash flooding.
While Australia has always had these disasters, our research reveals these new
extremes are the result of dramatic climate-driven changes in the upper
atmosphere above Australia.
Eight to ten kilometres above the ground, the fast-flowing jet stream air
currents have shifted further southwards, dragging rain-bearing winter weather
systems away from Australia’s southern coastline.
This means southern Australia has experienced at least 25% less annual rainfall
and is currently gripped by a continuing drought. Our findings should be a
wake-up call for governments, primary producers and residents of some of
Australia’s largest cities: the hotter, drier weather is here to stay."
