The Snake River Plane is track of past hotspot eruptions. If you want to see where “Yellowstone” used to erupt, just trace that valley from east to west. You’ll be going from most recent to least recent.So it seems the Yellowstone caldera is a deep pipe to the molten core, but the solid surface layers are on the move. So the place where it blows will be different over time.
Time scale of activity is on the order of hundreds of thousands of years.
For comparison, consider the onset of life on earth about 500 million years ago, with a dozen almost geologiic ages of a hundred million years or so.
Yellowstone is comparatively recent..... lol..... but about a thousand human lifetimes will pass by between Yellowstone caldera events.
Australia may look like a stable place geologically, as it has been geopolitically.
I had a sister who went on an LDS mission to Australia about 1962, and sent me a large fine map of Australia that I hung on my wall and studied and dreamed about.
I think there is spot that is just right for me.... a spring or something five hundred miles from the next water, about 600 miles northeast of Perth.....
Me and about five thousand cows..... huh?
This is like college parties, people have all kinds of ideas about when the fun starts or stops.To be clear, you're off by 3 billion years (likely more).
I know there's a path like that, I just think it's not all that simple. Some track it back across Northern Nevada across 12 million years, some want to see it start at Hell's Canyon.The Snake River Plane is track of past hotspot eruptions.

All the old thrust faults, from Utah to California, which saw hundreds of miles of new land accreted to the continent, and many of which have be reactivated as normal faults during the era of basin and range extension, are all considerably older than the track left by the hotspot. The two geologic histories aren’t all that hard to keep separate.I know there's a path like that, I just think it's not all that simple.

The larger context embraces some horizontal thrust plates that scrunched up and built the Great Basin ranges, and made a path in the cracks for orogeny, and gave material for chemical action that formed the large gold/arsenic deposits on the mountain flanks near the shorelines of basin lakes(Carlin-type deposits).
The thrust plate process rode on a relatively shallow molten insertion between solid layers that pushed in from the Sierras towards the Rockies, as far as Pikes Peak, and which has now receded with subsequent settling and block faulting along the ranges.
The volcanic zone from Northern California to Yellowstone is awesome, and might either be the "mother lode" of lava which fed the thrusting, or be the "daughter lode of lava" which drew from it. I think the geologic orogeny common to most Great Basin sites is 15Mya to 30Mya, so that was probably first.
The evidence is overwhelmingly clear: the solar minimum will not save us.with the prospect of a solar minimum, even a whole series of receding solar cycles that could run hundreds of years, perhaps cooling enough to deflate the CC Alarmists, the question could become how are we as a collective on a little vulnerable space rock gonna cope with an Ice Age. I don't think we're gonna hatch out with ideas like subsidizing folks who produce and burn carbon..... like paying the smudge pot crews, so to speak
But I really wouldn't be surprised I mean, it doesn't really matter what the facts are, or what the crisis is, as long good progressive foot soldiers are willing to float with the daily talking points. We can justify global power and arrogance with any crisis.
Yes, definitely.The evidence is overwhelmingly clear: the solar minimum will not save us.
Will ice grip the planet again, maybe even in a Snowball Earth event? Almost certainly, yes. Should that have really anything to do with current discussions of climate change? Certainly, no.
Don’t let me stop you from beating your favorite drum, but you underestimate the calamity that could very well ensue if the permafrost in the Arctic thaws and releases all that methane. It could totally **** food supplies for a decade.Yes, definitely.
Because anthropogenic global warming, with tipping points and all, will not be as destructive as world fascism uploaded with authoritarian but ineffective international commitments that actually doom us as a race.... as a human race..... far more powerfully than anything Nature will do.
The basic character of all government authoritarian propaganda is always falsehoods, outright if not somehow angling off of a few facts.
We are being told that we are setting record heat year by year, that the ice has melted in the Arctic and is melting in the Antarctic, but in the wrong context. These things happen without humans burning stuff. If we burned every last ounce of Carbon Earth has, and tried to restore the natural carbon dioxide atmosphere as it was billions of years ago, we would fail. Whatever carbon we could apply to the task would be soon depleted, and the inexorable processes of photosynthesis would begin again to store carbon and liberate oxygen. Nobody can imagine the quantify of Carbon Dioxide that was our atmosphere in the Precambrian epoch. That atmosphere would just crush us. We are not ever going back to that. The mineral deposits of carbon dioxide will never be significantly reduced. It's an inrreversible natural equation.
What you have is a new religion, another false religion like all the religions we can invent and establish as standards of conduct and belief. If anyone tries to be the iconoclast or heretic, they are just sidelined, marginalized, or yet thrown in prison and executed.
The basic tenets of the new age, of the Progressive or global system coming on, will destroy mankind except for perhaps a few oddballs that managed to hide out til the lunacy runs its course.

Everybody is handwringing right now about an economy that might only be able to run at 90%. The methane scenario would make 90% look like heavenly abundance.
Already had my heart stopped by that article.
