    I was just thinking about the poor air quality today and yesterday here in the Midwest, and then I see this. I want to be hopeful we can change this in my lifetime, but I am also not optimistic.

      Depends how old you are. I’m 47. It’s gonna far worse. The question is will my kids be the ones to say it’s bad enough? I don’t know. Maybe theirs.

      Also it’s hilariously optimistic that this chart only thinks a 4 degree rise by 2100. Seems very conservative.

      Personally speaking I’m investigating moving my family further north here in Canada to get ahead of the madness to come.

      I am optimistic. I will get downvoted to oblivion, but I want to share what I honestly observe:

      1. AI demand is driving huge investment in production of carbon-free energy at scale.

      Yes, AI is sucking up all the immediate term cheap fossil-fuel energy while it can. But it needs more, so it’s driving carbon-free investment.

      Immediate term with Small Modular fission Reactors (SMRs)

      … and immediate term, multiple commercial fusion energy plants are being built.

      2. Commercially viable carbon-free energy at scale is coming online in < 10 years

      SMR is real, exists today, and just needs economies of scale … and stable regulation. AI datacenters are driving the orders now and even if MAGA cultists keep USA out a few more years, science-accepting countries will be investing in clusters of those, rather than coal plants, when they see working examples and so less risk.

      The Fusion plants this decade will not be just prototypes, but plants that produce more energy as a whole than they take in, multiple times over, and ofc don’t produce nuclear waste. This is largely made possible by high temperature superconductors (which didn’t exist commercially when ITER was built) and a demo plant fully online in 2027

      EDIT: ofc we should reduce excess CO2 emissions immediate term, don’t misconstrue long term optimism for polyannish denial of imemdiate term emergency

        Nah, this is the same nonsense lie cryptobros tried to peddle. Any energy used by AI is energy which could have been used for something more worthwhile, carbon-free or not. And most of it is far from carbon-free.

        AI as it now stands gives me quite the opposite of hope. It’s only intended to enslave the working class and further transfer wealth to the top 0.01%, as is fusion.

        Solarpunk gives me hope.

          Well, maybe you aren’t aware of how it’s being used to design proteins to create therapies for pretty much… everything, from cancer to Crohn’s. Another 2-3 years before you see products in human trials.

          Or how it’s revolutionized climate science and weather forecasting.

          If all you see is the hype Grok images and SEO slop, it’s reasonable to reject the technology. But that would be deeply misguided.

            I’m aware of the promises of AI, yes. LLMs are trash. Folding proteins is awesome. Nonetheless, it’s all controlled by the ultrawealthy, and that is THE problem today, which AI ain’t solving for us.

        I feel like AI companies are creating a large demand for energy no matter where it comes from, and feel like having some minor investments in potential carbon free energy is mainly a marketing ploy or something to point at if they ever get sued.

        Immediate term with Small Modular fission Reactors (SMRs)

        Tbh, the big problem with nuclear in america is that we don’t really have the federal power needed to actually coordinate and mandate the needed infrastructure for it. The US is so obsessed with state rights that we’re susceptible to nimby attacks and disputes at the local and State level governments.

        To actually cut through the red tape, we’d have to empower federal agencies for a good reason for once, and I’m not very optimistic about our current political climate.

        and immediate term, multiple commercial fusion energy plants are being built.

        Yeah… I think it would be more accurate to say that fusion experimental sites are being built. Most nuclear engineers I’ve heard talk about fusion are still skeptical about fusion being viable in the next 20 years.
