"Tens of thousands of fish have died off northwestern Australia, as a large and
long-lasting marine heatwave intensifies.
The fish kill at Gnoorea Beach near Karratha is concerning our team of
scientists, as the hot mass of water heads south towards Ningaloo Reef and the
seagrass gardens in Shark Bay. That’s because we’ve seen this before. An
enormous marine heatwave in 2010-11 devastated fisheries and ecosystems further
down the WA coast.
This marine heatwave began in September, with temperatures up to 3°C warmer
than usual off Broome. There’s no end in sight.
The heatwave comes as oceans worldwide experience recordbreaking heat, driven
by climate change. More than 90% of all heat trapped by greenhouse gases goes
into the oceans.
The fish kill is a visible way to glimpse a disaster often out of sight and out
of mind. But these marine heatwaves do much more, from wiping out seagrass
meadows and kelp beds to trashing fisheries."
