  1. 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."

  2. 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."

    Chan, F., Sokolova, I. & Vopel, K. Ocean hypoxia: The science of climate change in the sea. Sci Rep 15, 4260 (2025). doi.org/10.1038/s41598-025-867

  3. 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."

  4. 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.

    "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 #Paleocene​EoceneThermalMaximum (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."

  9. Cattle, Cowboys & Climate Chaos

    https://ethicalrevolution.co.uk/cattle-cowboys-climate-chaos/

    In recent decades, scientists have warned that industrial meat production, and beef in particular, fuels climate change and leads to deforestation, soil erosion, species extinction, ocean dead zones and high levels of methane emissions.

    Yet today’s average American still eats three hamburgers per week! 🤯 🐮 🤮

    The rise of an extensive and powerful American beef industry thanks to the near-elimination of bison across the United States in the 19th century led to beef becoming a marker of American identity.

    Over a century later is now the time to forge a new identity?

    Certainly if we’re hoping to avoid the impending destruction of society-as-we-know-it a lot of us are going to have to address the cow in the room.

  10. Through Hurricanes Helene and Milton, Amateur Radio Triumphs When All Else Fails

    While some residents in hurricane-impacted areas can’t send texts or make calls, #AmateurRadio enthusiasts are helping communicate requests for help and messages between loved ones.

    Wired
    9 October

    "Hurricanes have wreaked havoc on the United States over the past month. More than 200 people have been confirmed dead as a result of #HurricaneHelene and many more have gone missing, making it the most destructive US hurricane since Katrina in 2005. Nearly a week after Helene made landfall, #CellService #DeadZones plagued the Carolinas, leaving thousands of residents unable to reach their friends, families, and even emergency responders. As #HurricaneMilton builds in the Gulf of Mexico this week, radio operators in #Florida are also preparing to launch their net—a group of operators communicating live over the air. Scott Roberts, an amateur radio section manager for northern Florida, said that operators in his area started checking their equipment and making plans to deploy to shelters as of Monday.

    "There are more than 1 million licensed radio amateurs in the US like Witherspoon and Roberts, according to a Federal Communications Commission spokesperson who spoke to WIRED last week. Some amateur radio bands are short bands, reaching only small communities of people, while others cover hundreds and even thousands of miles. When #CommunicationInfrastructure fails, like #CellularNetworks during a natural disaster, the FCC allows for amateur radio operators to assist in recovery efforts.

    "Gordon Mooneyhan, spokesperson for the American Radio Relay League, said he knows of three main #repeaters being used to convey messages inside the disaster area from Hurricane Helene, including the #MountMitchellRepeater, which is located at the highest point in #NorthCarolina at 6,600 feet and boosts localized radio broadcasts to a wider network. This is where Witherspoon read off supply requests and #RoadClosures."

  11. Deoxygenization is happening. Dead zones are increasing in number and size.

    "Oxygen levels in the world’s oceans have already dropped more than 2 percent between 1960 and 2010, and they are expected to decline up to 7 percent below the 1960 level over the next century."

  12. 4. Biochar reduces the very serious problem we have with nutrient run off. #Nitrogen and #Phosphorous are important limited resources that currently leach out with each rain creating oxygen-deprived #DeadZones in streams, rivers, and the ocean along with toxic algae and seaweed blooms like the big one currently headed for Florida. Nutrients are held in biochar so they don’t wash away and less frequent applications are needed - saving farmers $$.
