Is (Adelaide's) stormwater contributing to the toxic algal bloom?

"... Stormwater "had never been sexy" and, as long as it was flushed away, it did not get the attention nor the government investment it deserved."

"The EPA's Adelaide Coastal Waters Study (ACWS) summary of 2008 stated that nutrient loads had increased 30 to 50 times since European settlement, and recommended steps to reduce wastewater, stormwater and industrial inputs. The study found the loss of seagrass was "mainly due to stormwater flows" "

The Guardian: Marine heatwave over Pacific Ocean could lead to flooding in north-west

Severe ‘blob’ or marine heatwave can lead to increased inundation and wintery weather in eastern North America

"...A marine heatwave known as a blob was especially severe this year in the north-western and central Pacific Ocean, which could lead in the coming months to increased flooding in the US Pacific north-west and especially wintery weather in eastern North America, according to climate scientists.

The temperature in August in the northern Pacific was 2.5C above preindustrial levels, according to Berkeley Earth, a non-profit that studies global warming...."

North Pacific Records Unprecedented Marine Heatwave Linked to Climate Change and Pollution Changes

The north Pacific Ocean experienced its warmest summer on record between July and September 2025, with sea surface temperatures surpassing previous highs by over 0.25°C. This extensive heatwave, covering an area roughly ten times the size of the Mediterranean, has puzzled climate scientists. While g... [More info]

#Jellyfish Shut Four French #NuclearReactors as #HeatWave Builds

By Eamon Farhat

"#Electricite de France SA [#EDF] was forced to shut four #AtomicReactors after a swarm of jellyfish clogged up filter drums at its #Gravelines power plant.

"The 'massive and unforeseen' [um, not if you read my posts -- very much FORESEEN] presence of jellyfish in the filter drums of pumping stations closed four out of six reactors at Gravelines on the north coast of France, EDF said in a statement on Monday. Pumping stations for coastal #NuclearPlants usually draw in sea water for cooling, sometimes exposing them to marine life.

"A #MarineHeatWave is intensifying off the west coast of France, with unusually warm waters in the English Channel near Gravelines, data from #Copernicus Marine Service show. Jellyfish populations can 'bloom' at such times, and France has closed several beaches in recent weeks due to invasions of the eight-legged molluscs, according reports compiled by the beach information app Meduseo."

Warming the climate and run off is making harmful algal blooms worse
Turning the ocean into a lifeless 'dead zone'

"The scale of each harmful algal bloom event seems to be increasing...We're basically seeing that the warming climate is changing the frequency and length and locations and toxicity of harmful algal blooms...If there isn't something done to mitigate, to reduce climate emissions, warming will continue and these kinds of events will be more and more likely."

"Climate change is an existential problem of planetary proportions."

"The International Court of Justice (ICJ) has issued a historic advisory opinion that could reshape the global legal landscape for climate action, declaring that States have binding duties under international law to protect the climate system and that a failure to take appropriate measures may constitute an internationally wrongful act."

"The ICJ also addressed the oceans, affirming that anthropogenic GHG emissions qualify as “pollution of the marine environment” under UNCLOS, triggering obligations for States to “take all measures… necessary to prevent, reduce and control pollution.”

Widespread marine species mortalities a ‘human-mediated disaster’

"Effects of marine heatwave driving ‘foreseeable’ SA algal bloom could rival black summer fires, scientists warn."

“Alongside rapidly reducing emissions, Australia needs to be better prepared for environmental disasters such as this. We should all accept that this is likely to just be the tip of the iceberg for what our future looks like with unmitigated climate change and rapid biodiversity loss,” James Trezise, Biodiversity Council director

"Prepare for “an increasingly dangerous and unstable future.""
