Brewing oceans, brewing storms, making a blooming disaster

"Over the past year, Australia’s oceans have been hotter than ever before...The continued burning of fossil fuels has caused our atmosphere to warm by approximately 1.2 degrees C since the pre-industrial era....If you change what happens in the oceans, you start to change the whole system...The problem with climate change is we’re hitting that system incredibly hard with extra energy and we’re putting a lot of pressure on the oceans."

Global oxygen decline in the ocean
Ocean hypoxia: The science of climate change in the sea

"... The field will need to draw on ... advances to meet demands for adaptation solutions to the continued progression of global ocean deoxygenation, particularly in conjunction with ocean acidification and marine heatwaves in a multi-stressor scenario."

PFAS contamination in NSW waterways

" "This inquiry really did uncover the delays and in some ways the inability of the government agencies to admit that we have a problem," Ms Faerhmann said."
"We've known about these chemicals for 25 years … the EPA has been asleep at the wheel over this."

Lives disrupted and stunted by ongoing climate disasters

"Unicef-commissioned report shows being unable to finish high school – and the associated wage loss – is the most significant impact of increasingly frequent disasters on young people. Experts and advocates fear the lifelong consequences facing young people are being overlooked in disaster responses as what were previously known as “one-in-a-hundred years” disasters increase in frequency and severity."

"Unicef Australia is calling for the government to create a policy framework to support young people during and after natural disasters. “[We need] a better plan around the things that children need, around education and having enough supports to help them with their mental health if they’re traumatised by an event."

Fossil fuels, Marine heatwaves and Runoff: The bloom pulsates

"Algal blooms are complex, but the prevailing theory is that the 2022-23 floods washed nutrients down the Murray-Darling Basin system and out to sea. A marine heatwave and an “upwelling” of nutrients from the bottom of the ocean combined to create the perfect conditions for Karenia mikimotoi to flourish."

Extreme temperatures bake barnacles in tide pools

Tide pools contain thousands of lifeless molluscs and barnacles when the air temperatures is above 46C (116F).

Legal stoush between NSW and commonwealth halts crucial water flows into Murray-Darling

“This delay of critical water for the rivers is a result of a system that has been designed to prioritise irrigators over environmental water."

'It's a sick river. There are dangerous contaminants.'

"The Belubula River is an endangered ecological community.

"Foam containing high levels of the forever chemical PFOS have appeared on a river in central-west NSW for a second year.These concentrations just in the river are bad."

'Future studies should include the assessment of likely real exposures: platypus, livestock or humans, together with PFAS fingerprinting," Professor Naidu said."
