Earth May Have Breached Seven of Nine Planetary Boundaries, Health Check Shows (theguardian.com) 74

Industrial civilisation is close to breaching a seventh planetary boundary, and may already have crossed it, according to scientists who have compiled the latest report on the state of the world's life-support systems. From a report: "Ocean acidification is approaching a critical threshold," particularly in higher-latitude regions, says the latest report on planetary boundaries. "The growing acidification poses an increasing threat to marine ecosystems." The report, from the Potsdam Institute for Climate Impact Research (PIK), builds on years of research showing there are nine systems and processes -- the planetary boundaries -- that contribute to the stability of the planet's life-support functions.

Thresholds beyond which they can no longer properly function have already been breached in six. Climate change, the introduction of novel entities, change in biosphere integrity and modification of biogeochemical flows are judged to be in high-risk zones, while planetary boundaries are also transgressed in land system change and freshwater change but to a lesser extent. All have worsened, according to the data. Stratospheric ozone depletion has remained stable, however, and there has been a slight improvement in atmospheric aerosol loading, the research says. At a briefing outlining the findings, Levke Caesar, a climate physicist at PIK and co-author of the report, said there were two reasons the levels of ocean acidification were concerning.

    Are these conditions ANDed together, or ORed together, to determine whether we're irreversibly screwed? And if it's ORed, does this mean we should have given up twenty years ago?

    Actually, now that I think about it, I guess we DID kind of give up twenty years ago. At least.

    When I read the title, but not yet read the text, I wondered what that meant - "Earth May Have Breached Seven of Nine Planetary Boundaries".

    If you still accept Pluto as the 9th planet, then I thought the title referred to the solar system.

    What I imagined the title meant was that man-made volatile industrial chemicals, synthetic organics that do not occur naturally, have diffused outward far enough to cross the orbit of Uranus. For Uranians and Neptunians, detecting them would be an indicator of life elsewhere.

    Admittedly, I completely misunderstood the title, but that is now an intriguing question. Since we first started making synthetic chemicals in the latter half of the 19th century, are there any that could have diffused that far at detectable levels? Keep in mind that other than nuclear and the most powerful of conventional explosives, none would have had the high impulse of rockets and spaceships, so Voyager and New Horizons exhaust don't count.

    Any thoughts?

    We have all the warnings in the universe pointed at us, every day for decades now, and still, we barely move the needle on trying to stop ourselves. Being down here in the low-middle of the economy, while being told we're all gonna die, constantly, gets a tiny bit depressing at times. It's important. It's an existential threat. It's a political and corporate football that gets tossed around for profit and bullying, but it doesn't seem like anybody with the power to affect real change actually believes any of it. Because if they did, they wouldn't be meh'ing out on the bit where they, ya know, affect change.

    I'm wondering if anything about climate change really registers to the big movers and shakers. Will they ever notice? Or will they just keep moving themselves away from the worst impacted areas and then preaching at us that *we* all have to change, but they're not gonna because there's more profit to wring from the system before it all shuts down? We truly have prioritized greed over everything, even life itself.

      Oh, the people in charge do believe in climate change. It's just that solutions feature personal cost for global benefit. Participating puts you at a disadvantage vs other politicians, businesses, nations. If people even care, you can instead do much cheaper greenwashing (also good for milking hippies).

      You do have to wonder.

      Wealthy elites who talk most about global warming live on the coasts, in their, er, energy efficient mansions ... do they really believe that their properties are going to be underwater soon, with sea level rise?

      Maybe they do, and just use cognitive dissonance ... but you can see why us great unwashed might just have a few doubts about whether they really do believe it, as opposed to just using their supposed belief as a weapon. .

        Firstly, sea level rise is happening at different rates in different places (for well-understood physical reasons). So a lot of coastline is perfectly safe. Even for the bits that aren't, the timescale is usually many decades.

          Someone is throwing the 'great unwashed' a plausible but flimsy lie to try and manipulate their thinking - don't fall for it.

          The truly wealthy elites already have several different homes. I only know a few people that register that high on the pay scale, but all of them own three or more large-scale houses, plus a few smaller properties they use for vacation/get away from the fast-pace spots.

          When the water comes, I expect most of them will be handsomely compensated. Hell, most of them will probably get a government bailout along with a formal apology from the president at the time.

        If you dig into the science with an open mind, you can't really deny the truth of it happening. It's just happening slowly enough that the big power players can literally believe that it's happening, yet disconnect when they look at their homes near the water because, "Hey, it ain't washing us away yet." People do that. Even us little people. We just hurt ourselves. They have power, so their ignorance/cognitive dissonance hurts more than just them, but it's the same principal.

    Admitting up front that I don't know anything about the actual theory of "planetary boundaries", nevertheless my BS meter is triggered by claims such as this one: "[Planetary boundaries are] thresholds beyond which [planets] can no longer properly function...".

    Indeed? And how, precisely, would they know this? Are there other planets whose "functions" we can assess to determine what is "proper" and what is not? And why are you using words like "threshold" in reference to dynamic, chaotic systems such as whole planets? Feedback-driven systems are characterized by thresholds, they undergo periodic cycles.

    And don't get me started on the limits of our knowledge about even our own planet.

    The main indicator of "oh noes, acidifaction is killing the planet" was the state of Great Barrier Reef. You may remember same scientists claiming that it getting bleached was a good litmus test of just how lethal oceanic acidification was for life in the oceans.

    I bring good news. Great Barrier Reef has never been better. Latest report showed coral cover numbers higher than ever since they began measuring it. It is doing so well, the report had to focus on "but there are many potential risks" and pointedly ignore the current state and the developments of last half a decade to continue the narrative.

    This is likely why we're now getting these sorts of propaganda articles now, as the report on its condition was released recently, and so reinforcement of narrative of ocean acidification just utterly murdering life in oceans needs to be reinforced in public's mind to maintain grants.
