This is the sort of irreversible change that a warming planet brings. This algal bloom may stay with us permanently. Or, it may become a recurring nightmare for ocean life and residents of South Australia into the future. It is not going to go back to the way it was.
As the global temperature rises above 1.5C in coming years, it's one step away from such blooms spreading wider, to many locations across the world. Already there are blooms along coastlines of Southern California, Brazil, China, South Korea, India, Persian Gulf, inland lakes in South Africa and Kenya, Baltic, Northern Ireland, Adriatic, Belgium, SW England, Lake Erie, and Florida.
Warning! - there is worse to come as marine heat waves increase in both extent and location. 90% of the energy we have trapped has gone into ocean waters.
Poisonous waters, anoxic zones, dead marine life. This is a direct threat to one of our main sources of food and we have 8 billion mouths to feed.
We need much more action from our governments. We are pushing 1.5C and some scientists say we are already committed to passing 2C. We are almost out of time - only a few short years left to get to zero and we certainly can go a lot faster to zero carbon.
We must stop approving coal, oil and gas and transition off what we already have. We must shut down the fossil fuel industry.
Please, please... go and talk to your representatives. Stop this madness before it is too late. Time is short.
On Kangaroo Island – where the bloom has washed death ashore for almost a year – a group of citizen scientists are focusing their efforts on "what’s still out there".
