You are not reasoning. You are, in effect, using a cooking recipe book to describe how to fix a car.

What they'll possibly try to do now is to lose that mess in a bigger mess that'll they'll try to create, going forward. Trash the political landscape with strategic lies and uncertainties to level the increasingly asymmetric situation they now face, and then convince people they are the way of this mess. Sound familiar? Then, pull out Project 2025 again as a solution.

Taken in aggregate with his support of Project 2025 and other stuff, a duck is a duck.

The air blowers will reduce the amount of natural carbonic acid, which is highly unstable in a turbulent environment. You might knock it down to the same pH as the catchment water if you turn off the blowers to find out. You only need to expose the lake surface to the atmosphere for it to oxygenate. The air blowers function is to temporarily disrupt the surface tension to allow gas exchange, it doesn't actually force air into the water directly. A bottom/up circulation should provide sufficient exchange without agitating the water too much, such that it liberates the carbonic acid as carbon dioxide. The carbonic acid is an integral part of the lake's natural pH management system. My reference is experience in dealing with persistently rising pH in hydroponic systems. Took me a long time to figure it out. Look into the carbonic acid cycle if you want to understand it more deeply. TLDR. Aim for water circulation from lower down to rise to the water's surface for gaseous exchange without agitation. I think the pump can be lifted some way off the lake bed, say mid-water, to avoid making the water cloudy and turbid from sediments. Plan your pump arrangement so that the water body moves around in a manner that covers the majority of the lake. The rain and wind will also contribute to breaking up the surface tension for gas exchange, so it doesn't have to be all artificially generated. You could try this as an experiment in a bath of the lake water and monitor the pH as you play around with it. To start, put some lake water in a mini-lake arrangement and leave it undisturbed, whilst monitoring the pH over time. It might take a few days. Then play around with your circulation pumps to find the best circulation pattern.

60-100psi.

Yes, although I'm not sufficiently competent myself, I appreciate that verbosity is no substitute for mathematical descriptions.

Why make a big deal out of it? I see the title as someone who is RELATIVELY knowledgeable on one or more of the 3 main branches compared to the sites general readership. I think you are nitpicking. Careers or degrees aren't made or lost on this forum. Someone doing a degree will not rely on one source.

It looks like to me that it is not possible to relate every single detail and at certain level, like yours, there needs to be a minimum of knowledge on the part of the questioner that needs to be assumed they have.

Here's the clip shown by Adam Schiff on Twitter: https://x.com/i/status/1817007890496102490

I've seen pretty much every member argue with each other, one way or the other, over the years, on matters of science. I think anyone would be called out if they were consistently saying unscientific things. In a nutshell, I think the peer review outlook is pretty good here. Maybe not as strict as somewhere like Physics Forums, but that's not for everyone, including me.

With Harris up now against him, the contrast is much clearer for voters to see. He's a walking train wreck and sewer mouth.

I think he's covering for Trump. I think it's plain as day what he means. If it walks like a duck... and he is a duck.

This is why it's important to have as many players in a biosphere as possible to minimize the effect of a significant population alteration of a single species. If populations are moderated by competition, so is a biosphere. Catastrophic population change is ok as long some form of life can persist in the adverse environment until organism diversity can resume and evolution begin again. I think no species is favoured, only that DNA/RNA, as the information/pattern/signal carriers, can persist. As long as the minimum information survives, so can life as it is. It doesn't have to start all over again from basic molecules compounded from astronomical events.

Absolutely, 'correlation is not causation' has to be kept in mind.

In the predator-prey dynamic, the weak can act as a buffer and keep the predator fed, but those with the environmentally superior genetics can be left to survive a bit longer to reproduce. This benefits the predator as well by ensuring continuity of food supply.

The weak may carry genes that could could help us survive through some future catastrophe. Sickle anaemia confers some some protection from malaria, for example. A weakness is only one when that condition doesn't help an organism prevail under a particular environmental condition; which can change. SCA confers a benefit in a malaria-prevalent environment, but is a handicap in a malaria-free one.

There are macro events that the biosphere can't change, vulcanism being one, and will inevitably have to adapt to it. It's not all one or the other i.e. dichotomy.

There maybe vested interests but they are competing vested interests. They are decentralized. Trump would neuter them to centralize the power around himself. Competition is good, monopoly not so much.

Harris has support of enough Democratic delegates to become party’s presidential nominee: AP survey Looks like the nomination part is probably going to be straightforward.

Lovelock is a chemist. Margulis is an evolutionary biologist.

Would the pressure at 5km deep make a difference to the rate of reaction? 1649atm.

Yes, the dinosaurs will stay as they are: dinosaurs.

It makes sense, she already has the exposure and is pretty solid. If she wins, it would be historic as well, and I think that's probably a plus. We said that earlier, didn't we?

Just read the BBC site. Holy smoking mackeral! I could hug him, even If I didn't agree with all his agenda. He can now leave with his legacy intact. What happens henceforth won't be down to him.

Humour comes out in stressful scenarios. I suppose it's a way of stepping back a bit. Last thing one needs to feel is concern turning into fear. It looks like we are now leaving peace and heading for a global conflict on many levels and not just militarily.
