Overshooting 1.5C Climate Target 'Inevitable': UN Chief (nzherald.co.nz) 78

UN Secretary-General Antonio Guterres says it is now clear that efforts to cap global warming at 1.5C above pre-industrial levels will fail in the short term. AFP: Before next month's COP30 climate summit in Brazil, Guterres said going beyond 1.5C would result in "devastating" yet predictable impacts. "One thing is already clear: we will not be able to contain the global warming below 1.5C in the next few years," Guterres said at the UN's World Meteorological Organisation (WMO) weather and climate agency in Geneva.

"Overshooting is now inevitable. Which means that we're going to have a period, bigger or smaller, with higher or lower intensity, above 1.5C in the years to come." However, if leaders start taking the problem seriously by driving towards net zero greenhouse gas emissions, "the 1.5 still remains -- according to all the scientists I met -- possible before the end of the century."

      You cut off the conclusive part - we're going 1.5C above baseline. How much, being open in part to what we do now.

  • This was inevitable.

    It was idiotic to proclaim 1.5 C as a target in the first place. I suppose that there are people who advocate for setting targets that won't be achieved, on the belief that this makes people try harder, but my thinking is that setting targets that won't be achieved only defeats the purpose, by conditioning people to give up.

    There was never anything particular about the 1.5 C goal, other than that it's a conveniently round number. It's slightly worse than 1.4 C, slightly not as bad as 1.6

      On this page they identify 1.5C as the initial "tipping point" of specific bad things. There is a fairly wide uncertainty around that estimate, but it's considered the best estimate so in that sense it wasn't picked out of thin air.

      • "There is a fairly wide uncertainty around that estimate,"

        Exactly. On that page the error bars around the 1.5 C figure are so large that the specific number really has no meaning,

        And the error bars around the other seven global tipping points are even fuzzier,

  • Yes, climate change was completely preventable if we properly pursued nuclear energy. Instead we burned fossil fuels instead.
    • No beef with nuclear power, but I have to say when I read that subject line, just by itself, my first thought was nuclear winter as an outcome of "if we went nuclear" that would certainly reduce average climate temperature trends.

      What especially galling is the fact that money is totally fake (we made it ourselves and its value is arbitrary) yet it is driving us to extinction in the form of low birth rates, pollution excuses, energy stupidity, etc. with the exception of a particular dog in South America, humans are the only creatures that need money.

      • It isn't money, per se: it's the add-on benefits of money. The real driving factor is biology. We - most of us - have an innate need to boink like rabbits to create the next generation. We also want the best mate - mates, if you're not very monogamous - so like primitive animals, we gussy ourselves up to alter our presented reality, in the hopes that we'll catch the eye of a promising specimen. We use money to augment our appearances; buy flashy cars; rent fancy apartments; etc. And, since we want our

    It is going to take a rouge country or billionaire to unilaterally initiate a geo-engineering program like stratospheric aerosol injection (https://en.wikipedia.org/wiki/Stratospheric_aerosol_injection) to save us all. Pakistan is one of the counties suffering the most from global warming, so maybe they will crack and undertake this mission to save the rest of humanity from their own stupidity. The clock is ticking. Our warming atmosphere is already demonstrating positive feedback on natural methane production and within 70 years natural methane will overtake human contributions to global warming if we do not act quickly to prevent this scenario. At that point, if humanity wants a cooler planet, geo-engineering will be the only choice.
    • Stirring the pot that way will create unpredictable and likely horrifying side effects. Ask the people of Springfield.

      Easy there, Ted Faro. :) Join us in the real world. The "clawback" that worked in Horizon: Zero Dawn isn't going to work in real life. You can't fix a planetary crisis with money and some technology. The idea that one nation or tech mogul can single-handedly geoengineer us out of this mess is just hubris of the tech-bro variety. Stratospheric aerosol injection might look like salvation, but it’s just as likely to wreck monsoons, acidify oceans, and torch what’s left of our climate stability. If we want to keep Earth from turning into Arrakis (to borrow from another excellent fictional world) it won’t be through a billionaire’s good intentions -- it’ll be through collective effort, shared sacrifice, and the will to change before the biosphere collapses.

          Fair point — optimism is a tough sell in this atmosphere (pun also intended). But climates do change — that’s the whole problem and the whole opportunity. Political ones can shift faster than planetary ones if enough of us keep turning up the heat where it counts: at the polls, in the markets, and in our own habits.

          If we can engineer the weather with aerosol jets, surely we can engineer a little political will. The trick is to start the feedback loop in the right direction this time.

      • You can't fix a planetary crisis with money and some technology.

        hmmm... what if an engineer managed to create a way to pull CO2 out of the air and break apart the carbon and oxygen, sell the oxygen to rocket launches and made carbon fiber thingies out of the carbon and sold those... all while using sunlight to do all the work?

        Not saying this is likely, just pointing out that your proclamation may not be quite as solid as you think.

          You’re right that I should’ve written “with only money and some technology” — I thought the "only" was implicitly obvious, but I am happy to spell it out for you. To address your hypothetical, I'll provide one of my own: If an engineer really could build a self-sustaining photochemical CO cracker that turned greenhouse gas into profit, they’d already be running the table on carbon markets and Nobel nominations alike. The fact that nobody has done so isn’t because

            Or do you have some issue with collective action and personal responsibility?

            Why do you think I was speaking about collective action and person responsibility? I took issue to your assertion that money and tech couldn't solve the issue. It could. It probably won't, but it could.

    No one with the power to do anything, will take it seriously, that's been proven over decades. There is no debate to be had about climate change, there wasn't decades ago, but at least for the last decade it's been absolutely irrefutable. I don't understand what anyone is hoping for any more, effectively those in power adopted an Agile / Lean methodology so they could act as if they were seeking progress, well, not doing anything, and feeling empowered.
    • Yeah, we're fkd. They covered this pretty well in Don't Look Up, but I don't think they were grim enough. In reality, we're even dumber than portrayed. I'm looking forward to my "finish line" on this crusty ball of magma, but I feel bad for my kid and grandkids.

A container of Tide Pods, which I didn't need overnighted, but didn't have another option, and didn't need multiple boxes, with packing protection.

If the entire world had gone all in on nuclear for baseload and a whole bunch of other things (no airplanes for you, more than half of my CO2 budget is flying), then it might have been possible, but that was never going to happen.

Unfortunately, this problem lacks negative feedback: The ruling class will be protected by the corpses of those unable to buy protection.

        I'll be clear: I've never seen anything that would convince me that global warming is real. EVEN BILL GATES HAS TURNED AWAY FROM THE ALARMISM. I have seen a few things that are compelling, but there's a big gap between compelling and convincing.
