  • The world has its own CO2 cycle so it’s not that we need to reach 0, we just need to reach a balanced emission threshold. Though at this point we will also need to aid this process with further removal.

    The issue is mostly that we are outputting too much. Shipping industries, energy production, other transport such as cars and planes. These industries are a big part of the problem and the ones fueling (e.g. oil) them are the ones most interested in your feeling of hopelessness, as then they have free reign over their actions.

    The world has and will get hotter. There will be more disasters. But it’s unlikely to be the end of civilisation. The more we act now, the fewer people will suffer.

    It’s not a hopeless cause at all. Look at our tech now vs 100 years ago. Humanity has the means to do it.



  • I have thought about it for a while but the US is basically in a cold civil war, with a significant chance of it becoming hot. And it looks very similar to their previous one. Neither side seem to have a charismatic enough leader.

    It’s easy to look over the pond and think it’s none of our problem. But if the US falls to chaos a lot of other countries will follow suit. We can already see this influence in the UK and I’d argue many other EU countries. Russia probably saw this weakness, bet on it worsening much quicker than it did, but lost that bet (so far).

    With that said, addressing the US as a whole no longer makes sense. I’m sure plenty, plenty of Americans see what is happening.

    It’s unfortunate that one of the wealthiest people on this planet has taken the anti-democratic side, but it’s not the first or the last time in history a powerful man, rich beyond measure has done so.

    It’s about which forces act on them. Other than neutrons, every particle here will interact with charged particles (e.g. electrons or protons), which makes it an EM interaction. In the world of particles, EM is long range. Whereas the force that acts on neutrons is very, very short range. There’s no actual touch the way we think of it, outside exotic conditions like in supernovae. Think of the size of a nucleus vs an atom. Those are the two forces keeping them together.

    The way concrete stops neutrons is similar to a pinball machine. It doesn’t need to be a solid material, it just needs to be dense. It just so happens that solid materials tend to be denser. But for example, older nuclear reactor designs use water to slow the neutrons.

    Btw this is a very clever use of water and by no means dinosaur tech. We just have more clever materials now, e.g. molten salt.
