  1. At some point “point of no return” is like “per my last email” for climate scientists..

  2. “could set irreversible course by triggering climate tipping points”

    could? That is just gullible positive spinning. The course is already irreversible even before “drill baby drill” won.

  3. Is this 2015?

    We been knew. Did major companies act and governments act accordingly? Not by a long shot, in fact we’re going in the opposite direction.

    Fuck capitalism until extinction comes.

  4. I’m fairly certain geoengineering is going to be the outcome at this point. And that will lead to some really messy politics as countries fight over who controls the thermostat.

  5. We probably won’t take it seriously until a city is permanently under water or a wet bulb event takes out a region, crops and all.

  6. Eh, who cares.

    Let’s crank out more AI datacenters so we can make lame images and videos that suck the remaining wonder and truth out of the world, and outsource our brains, so we can concentrate on over-consuming shit we don’t need, while we frolic in the sun as it cooks us.

    Also the billionaires need to be kept happy with their imaginary numbers.

    Wheee !

  7. It’s been 20 years since “An Inconvenient Truth” was released.

    Batman has been rebooted twice since then. It’s overdue.

  8. We were screwed the last 3 “points of no return”.
    At this point we’re just cooked… pun fully intended.

    what most regular people don’t understand is how many vicious cycles of warming occur e.g. warming tundra releases methane in clathrates in the tundra which increases warming. Right now we are experiencing unprecedented instability in the polar vortex which is producing extraordinary warming in the arctic which will produce more warming and may cause future polar vortex instability.

  10. Our leaders are so arrogant they don’t give a fuck. Humanity is doomed because of the greediest and most arrogant among us rule the world.

  11. You know how in Interstellar, even after the apocalypse, there was still “normal” life on earth. People talked on the phone, recorded videos, drove cars, went to sports matches, etc. And yet, it was still undoubtedly post-apocalypse? That’s gonna be us in 50 years. Except for us, there will be no magic black hole with Matthew McConaughey in it.

  12. I have a theory. The world leaders already know this and they also know that 8.5 billion people and growing is unsustainable with capitalism. While they will denie it, they already have plans to reduce the population by half, once robots and AI are more up to speed. I bet at some point there will be a controlled war that will eliminate a large portion of society. The rest of the 4.5 billion will mostly die out from lack of support or modern day slavery. This is the only way to re balance society and the planet. While I hope this isn’t the case, being realistic makes this seem more likely. AI and the wealthy can figure out this problem, but not with 8.5 billion people.

  13. I live in Ireland.

    We’re known for various things, but hot weather is not one of those things. If we get one nice weekend in June or July that’s usually ‘it’ for the summer. We’re talking sunny and about 21/22 Celsius.

    I had to buy an air con unit this summer. My bedroom was like a sauna every night for weeks. Fans were just not cutting it. When the sun’s going down at 10pm mid summer and it’s still 28 degrees outside that is just *not normal*.

    My house is not built for 32 degree weather, it’s built to retain heat and keep the ever present rain out. The sun should not be trying to end my life. I get sunburnt looking at people’s holiday photos.

    Go full moon project on carbon capture, screw the cost. That’s the only way, but nope, gotta keep 75 year old billionaires and tech bros rich. Climate disaster just changes where the rich vacation. Fixing it will make them SLIGHTLY less rich so can be having that. A few billion people dead isn’t a bother to them, missing out on a few billion more dollars does.

  15. It’s not like we can change anything as long as megacorps and billionaires keep ruining the planet for short term gains. And most of them are old enough to never see the fallout of their greed.

  16. Sorry I could not hear you over the giggles and laughing of the elderly billionaires and powerful people, thinking about the last Pennie’s they will be able to scrape up, before dying comfortably of old age.

  17. We have known this for many many decades, I think people stop caring at this point as the entire world is ran by corrupt fuckwads who will sacrifice anything for their own gain, whilst you’re trying to drink something through a soggy paper straw.

    While I do believe in man made climate change, these scientists has been saying this exact same thing for decades.

    It gives “boy who cried wolf” vibes. I hope this is not the time the wolf actually appears. But it’s clear something needs to be done.

  19. Humanity has never been capable of long-term thinking. I was watching the excellent first couple of seasons of Silo (AppleTV). For those unfamiliar, humans have been living in these deep underground cities for generations & the characters of the one we’re introduced to are just finding out a network of them—mostly failed—were built. I said to the sig other, “If people were capable of the advanced planning and engineering feats required to achieve even one of these builds, they’d also be capable of preventing the disaster.”

    Still enjoyed the show tho.

  20. When I was a child my mom told me my generation would save the world. I’m over 30 now and her generation is still in power actively ruining the world my generation was tasked with saving.

  21. You and your kids will have to deal with it, old people with 3 rental properties get to eat off it. Good deal lol

  22. Nothing will happen until basically something so horrible and out of left field happens with human deaths and only after several times of it happening in close proximity where it starts to really have a negative effect on the quarterly earnings reports.

  23. Point of no return being used so often it’s reminding me about all the unprecedented event talk from COVID.

    The arctic will be ice free in Summer by:

    * [2013](https://www.theguardian.com/environment/2008/aug/10/climatechange.arctic) as of 2008
    * [2016](https://www.theguardian.com/environment/2012/sep/17/arctic-collapse-sea-ice) as of 2012
    * [2016](https://www.theguardian.com/environment/earth-insight/2013/dec/09/us-navy-arctic-sea-ice-2016-melt) as of 2013
    * [2018](https://www.theguardian.com/environment/2016/aug/21/arctic-will-be-ice-free-in-summer-next-year) as of 2016
    * [in the coming decades, possibly the 2030’s](https://www.theguardian.com/environment/2023/jun/06/too-late-now-to-save-arctic-summer-ice-climate-scientists-find) as of 2023.

    And that’s why I don’t take climate doom reporting by the Guardian seriously. (There’s also [“oops it hasn’t shrunk in size since 2005”](https://www.theguardian.com/environment/2025/aug/20/slowdown-in-melting-of-arctic-sea-ice-surprises-scientists) now but there are a lot of nuances to that, see the article.)

    In terms of this specific article, I recommend comparing the claims made in the article, like

    > a hellish ‘hothouse Earth’ getting closer

    with the claims made in the study:

    > Are we now at risk of crossing planetary tipping points and triggering a hothouse Earth trajectory? Science doesn’t have a precise answer,

  25. “The public and politicians were largely unaware of the risk of passing the point of no return, the researchers said.”

    You know THAT is total bullshit.

  26. and this is entirely the fault of a handful of billionaires bankrolling climate denial.

    There is no amount of “reduce your household carbon footprint” that can cancel out the industrial scale carbon emissions either made directly by the industries that they control, or indirectly via power consumed from fossil sources enabled by weakened legislation that they lobbied to be weakened.
