Residents in a regional Australian town have woken to find millions of dead fish in their river.
The large-scale fish deaths were first reported on Friday morning in the New South Wales’ (NSW) town of Menindee.
The state’s river authority said it was a result of an ongoing heatwave affecting the Darling-Baaka river.
Locals say it is the largest fish death event to hit the town, that experienced another significant mass death of fish just three years ago.
In a Facebook post, the NSW Department of Primary Industries (DPI) said the heatwave put “further stress on a system that has experienced extreme conditions from wide-scale flooding”.
Heatwaves have become more frequent, more intense, and last longer because of human-induced climate change. The world has already warmed by about 1.1C since the industrial era began and temperatures will keep rising unless governments around the world make steep cuts to emissions.
