The earth has "flipped" magnetic poles many many MANY times. Only the scientists notice.
There is no such thing as man cause global warming. If anything we are entering a period of minima and it will get quite cold.
Only scientist noticed?
You should of told that to the creatures living at the time....
It wasn't a good day for them.
Pole shifts have no measurable effect on plant or animal life.
So you are certain about that?
I see two camps
What If Earth's Magnetic Poles Flip?
Valet agrees that a weak magnetic field could lead to the formation of ozone holes. He wrote a paper last year proposing a direct link between the demise of Neanderthals, our evolutionary cousins, and a significant decrease of the geomagnetic field intensity that occurred exactly at the same period. (That time, the lead-up to a geomagnetic reversal appears to have been "aborted"; the field weakened but didn't end up flipping.)
Other scientists aren't convinced that there's a connection between pole reversals and species extinctions. "Even if the field becomes very weak, at the Earth's surface we are shielded from radiation by the atmosphere. Similarly as we cannot see or feel the presence of the geomagnetic field now, we most likely would not notice any significant change from a reversal," Korte said.
The poles have flipped countless times (on average every 200,000 years IIRC)over the last 10 million years. Guess what. Nothing happened.
Agian I provided a link, you provided an opinion.
What's up with you thinking the poles shifting has no effect? It has been documented a few times that extinctions have taken place at the same time.
Correlation does not equal causation. The flips are relatively rapid but the extinctions have taken at least a million years in most cases. Even the asteroid theory die off took around a million years. There were multiple pole reversals in that time frame. Your link is a computer model. I hate to tell you but computer models are not data. They are a science fiction story and nothing more.
