An ecological disaster has been unfolding on Australia's coast

A mysterious, brown foam appeared on a beach an hour south of Adelaide. It was just the beginning of a toxic algal bloom that has now grown to thousands of square kilometres in size, killing precious sea life in its wake. Experts say it could be a sign of things to come.

The blame was placed on an “ongoing marine heatwave” which had seen water temperatures 2.5 degrees Celsius warmer than usual.

I wonder what prciptated the marine heatwave /s

On Kangaroo Island, which reported its first fish kills in March, some beaches were so littered with dead sea life, the smell was overpowering.
