In general, you're right, but jet fuel is one of the few things that we can't just "stop burning" right now. You simply can't replace jet fuel with batteries -- the energy density isn't there.

If some form of clean fuel were discovered, it would be amazing for air travel while we transition to electric planes, which will take a decade or more.

This is not that clean fuel, obviously, but we shouldn't discount fuels entirely.

Fill a cake pan nearly full with water and slide it sideways across the counter -- observe what happens. That's a pole shift.

Start with these videos and dig in to the other videos in those channels. the The first covers more of the global clues left behind while the second has a better handle on the physics and actual triggers. Every twelve thousand years. https://www.youtube.com/watch?v=-EAYgB07ZCE https://www.youtube.com/watch?v=WAlyvbt8Nlk There's that Ancient Apocalypse series on Netflix that covers remains of prior events too, although attributing destruction to asteroid impacts.

The best thing about hydrogen is that it requires very litle adjusment to convert natural gas combustion over to hydrogen. Already some succesfull converdion projects done for home heating. Omly hurdles are compact/save storage and clean generation.

also we've altrady have had multiple phases of the industrial revolution:

manufacturisation, factorization, electronification, digitalisation, automatisation...

We are still in a mix of digitalisation and automatisation, depending on what place we are talking about, but artificialisation is definetly somewhere in the mix soon.

If I’m remembering the article suggests there was a span of approximately 60,000 years between what they characterized as the onset of biodiversity loss and ecosystem collapse.

So geologically a blink of an eye but still 10x longer than the time since the Neolithic revolution and the adoption of agriculture.

The loss of biodiversity is reversible. We shouldn’t normalize defeatism.

Not exactly true. I had a Samsung robot vac about 6 years ago and it sucked (not in the way it was supposed to!), constantly getting stuck, eating cords, not finding it's way back to the dock, etc.

Newer vacs are WAY smarter, although you need to do some research and some are pricey. I got a Roboroc now and it's amazing. It's gotten stuck maybe twice in the 6 months I've had it, it keeps the floors spotless by vacuuming AND mopping, and is smart/capable enough to recognize floor types and lift the mop up when it hits carpet. If I move furniture around it instantly recognizes it and updates the map, it'll notice objects on the ground, recognize what said object is (cord, shoe, shirt, dog shit, etc) and both avoid it and let me know what it is. It empties its own bin, washes and dries its mop, and empties and fills its dirty/clean water tanks. I have a golden retriever who is constantly tracking dirt and fur in, but this robot keeps my place spotless with essentially no vacumming needed from me. With proper maintenance the little dude is a god send.

It should also be noted that time during which a geomagnetic reversal takes place is by any estimates 2k--12k years. So even if we're headlong into it, Comparatively, magnetic North's speedy yearly drifting would overshadow any observation of an overall movement of the poles to flip (if the pole's wobbles were a consistent-direction drift then it would be in the Antarctic within 400 years.) And because airport runways are numbered according to their magnetic compass direction (instead of true), the wobbly North pole means regular runway repainting, costing the aviation industry upwards of tens of dollars per year!

This is gonna sound gross, but work on those customer-facing skills. Being able to translate customer requirements into something that works for them will still be a thing. I don't expect AI will be able to do that part of the job for a while, savvy people will still be needed between idiot customers and the actual final product.

This will come when the end and restart comes. This will coincide. Almost all life, including nearly all humanity will die in tidal waves, earth quakes, and mudslides, the likes of which haven’t been seen since the last time this occurred. It’s all a cycle. Birth life death rebirth, and GOD is behind all of it.

Research the Younger Dryas, if you want real info on the last global reset….

We shouldnt anthropomorphise but people trying to monopolise the word "know" is ridiculous.... obviously it is not abstracting and visualising the individual concepts and stringing them together with language... but it knows that language object A and language object B are linked and it learned that by scanning its environment, the data it was given for training.

Saying that is sufficiently different from a person learning a word by, you guessed it, scanning the environment for links, that you cannot use the word "know" is pedantic and so stupid.

Maybe, but according to healthline resistance training (aka lifting) has also been proven to increase short and long term testosterone levels. Therefore, tradies are more likely to have those benefits as they lift heavy stuff a lot. Almost like that's what men were naturally meant to do.

Geophysicists measured a magnetic reversal happening 16.7 million years ago through centuries of lava flows. The field doesnt flip suddenly (like every 22 years on the Sun), but weakens and flickers over several centuries before reorganizing in the opposite direction. A magnetic compass would not be useful for navigation during this period.

Computer simulations of the geomagnetic dynamo also sees flickering, both with and without a reversal. Its possible we are merely in a minor flicker now or in the early stages of a full reversal. The intensity of the Earths field is down by 8% since first measurements about 200 years ago. There are claims of a stronger field millennia ago measured in pottery made from high iron clays. They would magnetize slightly after cooling off.

It will have consequences related to the Earth's magnetic field being significantly reduced during the midpoint of the transition.

The process will also probably take 1,000-10,000 years to complete, once it gets started.

There will be consequences, but the risk of you or I having to face any of these consequences, within our lifetimes, is almost nil.
