Yep. Some of the really really smart fellas say Yellowstone was and will be again one of if not the largest eruptions ever. Its also said we are overdue for a pole reversal. No one was around for the last one so no one is quite sure what will happen when it happens. I rather doubt the only result will be the water reversing its swirl down the drain.
You mean a magnetic pole reversal?
https://www.nasa.gov/topics/earth/features/2012-poleReversal.htmlHow otherwise would the north and south poles be reversed.
You mean the earth will tip over 180 degrees? Because Guam tipped over?
https://www.youtube.com/watch?v=v7XXVLKWd3QMagnetic pole reversal is a natural thing and we're overdue for the next one, so the smart fellas claim. Part of the reason they think they know this is that the magnetic field has been getting weaker over the centuries which is also part of the reason our climate is changing. The magnetic field is also our solar filter. No, I really don't think the Earth will make a back-flip. I'm thinking the poles will just up and change, don't know how long that take though. Mother Nature can be fickle about such things.
