"Perth has just had its driest six months on record, while Western Australia
sweltered through its hottest summer on record. Those records are remarkable in
their own right. But these records are having real consequences.
Unlike us, trees and shrubs can’t escape the heat and aridity. While we turn up
the air conditioning, they bear the full brunt of the changing climate. Our
previous research has shown plants are more vulnerable to heatwaves than we had
thought.
Beginning in February 2024, large areas of vegetation started to turn brown and
die off. With no real relief in sight, we unfortunately expect this mass plant
death event to intensify and expand.
Just like a coral bleaching event, WA’s plants are responding to the cumulative
stress of the unusually long, hot and dry summer. And just like bleaching,
global heating is likely to cause more regular mass plant deaths. The last time
this happened in 2010-11, almost 20% of trees and shrubs in affected areas
died.
This is in line with climate change models, which pinpoint south-western
Australia as a warming and drying hotspot."
