United States, Wales, Bjorn discussed on Uncommon Knowledge


Zero energy sources close quote within ten years. Good idea as first of all is not doable. And Secondly, even if could it be phenomenally expensive, and again, I think because this is clearly motivated by a lot of fear and so going out and say, oh, it's madness. I understand where this comes from by it's important to real people back and say, look if you actually want to do something about global warming. Let's two proposals. They'll actually work. Green deal first. And then we come to the proposals will actually work because that's urine Lombards job a promise to upgrade, quote, all existing buildings close, quote to meet energy efficiency requirements, again, I believe the promises to do that within a decade. And that's even more impossible. We're talking about one point three one point four trillion dollars per year. It's half of the US budget the stature budget. That's just not gonna happen. A promise to expand high speed rail service. So broadly that within a decade most airline travel will be rendered obsolete. I can't really see that happening. But but again, even if you did that that would actually reduce emissions a lot less because again air travel is a fairly small amount globally. It's about three and a half percent. It's probably more in the US. And I'm not sure what numbers, but still, you know, it's a fairly small, but it's the guilt amount. It feels wrong to fly in. So that's what we're focusing on again like. To focus in stuff, actually work. All right. So this brings us to what you believe should reasonably be done. You wrote recently of the work of economist. William Nord house you mentioned a moment ago that he has now received a Nobel prize the only climate economist every even though they'll prize quoting you Bjorn, quote, his careful work shows that globally coordinated moderate and rising carbon tax carbon tax could reduce temperatures modestly close quote. So that's something that to take place the imposition of globe modest global carbon tax and then ratcheted up gradually. Yes. So I'm going to complicate this a little further because he's absolutely right. And almost any comments you ask we'll say the right way. It's tackle a problem where basically you have market failure. Nobody's paying for emitting next analogy then put in a carbon tax if you can do that. And. And remember if you can make globally coordinated across the century with China, India, everybody else, then you can actually make this work, and you can cut carbon emissions a little bit in the however, the problem, of course, those that you you've seen this in the US, basically leads to gridlock for ten years in many other countries, you can't do it. If you start doing it as soon as it starts ramping up a little bit. You know, you got the yellow vests on on the street, and nobody can do anything in many developing countries have realistic carbon-tax would be so expensive that it would be more than the entire intake government intake. And of course, that won't be possible. So there's a lot of practical problems. So it's a neat theoretical point. And I think in principle, we should try and do it because probably is effective. Even if only some countries do it as soon as you don't do stupid stuff like then trying to impose carbon controls at the border, which a lot of people misuse to basically breakdown free trade, but the much. Much better approach to this is to focus on technology. And if you'll allow me sort of diversion, if you think back in the eighteen sixties the world was hunting Wales to extinction. Why because Wales has this wonderful aural that burns really brightly and really cleanly so lit up most of the US and and west European homes and our current approach to tackling global warming back then would have been a little bit. Like, could you please turn down that light? Could you have a little more dim? Could you have used the old annoying suiting oil instead? And of course, you would have had no success. What did happen was somebody drill for oil in Pennsylvania? And discover oh, wait there's a much cheaper even more effective that way that we don't have to go out and hunt whales, and we can burn on homes, it's cheaper. And it's even brighter. Let's do that that technological development basically, meant we save the whales and we've seen that number of times through human..
