#hypoxia — Public Fediverse posts

A multi-stressor scenario for the ocean and waterway ecosystems:

* The ocean is 'cooked' by the combustion of fossil fuels.
* Add a generous heap of 'nutrient-rich' floodwaters (runoff) from farms and suburbia.
* Get a harmful algal bloom (HAB) disaster, killing bio-diverse marine life and threatening the hip pocket nerve of coastal dwellers.

"A survey found that Australians remained far more concerned about disasters such as bushfires and flooding than they did HABs, despite 22 million people living with seven kilometres of the coastline and climate change modelling predicting more frequent and severe blooms."

"The study also found Australians had a "relatively low prioritisation of disasters — and HABs in particular — when compared with everyday socio-economic concerns"...Cost of living and healthcare dominated respondents' concerns in Australia, while environmental and climate change-related risks were perceived as less pressing.' >>

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."
