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."

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."

Mass mortality events
Dead marine sea life is washing up on the beaches
Mass bird deaths line the beaches
"There's a lot of concerning things going on with ocean ecology at the moment, so we are watching events like this with a bit of trepidation."

From 2021: An Ancient Era of #GlobalWarming Could Hint at Our Scorching Future [Bonus -- We're adding #PFAS, #microplastics and #radiation to the mix! Oh boy...!]
Looking back at the strange and sweaty days of the #PETM.
by Riley Black, August 16, 2021
"THERE WAS A TIME when alligators slid through weed-choked swamps near the North Pole. Some 55 million years ago—just around 10 million years after the mass extinction that killed T. rex and most of its kin—the average global temperature sat more than 20°F higher than it does today. Subtropical forests spread to northern latitudes, and mammals thrived in lush new habitats.
"The toasty weather had nothing to do with the event that killed the dinos. The driver for the climatic shift came not from above, but from below—in Earth’s oceans. Paleontologists and geologists suspect that some amount of natural warming that took place during the Paleocene, or the period following the die-off, caused great deposits of crystallized methane to transform into gas. Seabeds belched the excess out into the water and the air, which was bad news for the planet: Methane is a greenhouse gas far more potent than carbon dioxide. The globe rapidly warmed in response—jumping about 10°F in less than 20,000 years—and held steady for some 70,000 more before starting a long and slow recovery.
"Paleontologists call this hot spot the #PaleoceneEoceneThermalMaximum (PETM). It’s a time when subtropical forests spread over the continents and new animals got to stake their claims on the planet, all thanks to an atmosphere and oceans in turmoil. This part of the fossil record is a remnant of the past, but it may also be a preview of our future."

Vast areas of land are now dominated by one species – purple moor-grass – and good luck with seeing a bird or insect there. How do we revive these habitats, asks Guardian columnist George Monbiot
