Magnetic reversal may now be in progress - BGS

17 Jan 11 - "According to the British Geological Survey (BGS), we could now be headed into a magnetic reversal."

The BGS goes on to say that Earth’s magnetic field has had many highs, lows and reversals in its past, with the last reversal taking place around 800,000 years ago. I take issue with this date because there have been many magnetic reversals since that time.

There's the Gothenburg magnetic reversal of 11,500 years ago, when the mammoths went extinct.

There's the Mono Lake magnetic reversal of 23,000 years ago, when the earth descended into catastrophic glaciation.

There's the Lake Mungo magnetic reversal of 33,500 years ago, when the Neanderthals went extinct.

And there are several others, such as the Laschamp, the Blake, Biwa I, Biwa II, Biwa III ... the list goes on. (See Magnetic Reversal Chart.)

There's even the Big Lost magnetic reversal of 640,000 years ago, when - just by coincidence? - the Yellowstone supervolcano erupted.

In fact, my research shows that our planet undergoes a magnetic reversal about every 11,500 years and, agreeing with the BGS on this point, I think the next reversal is now due.

The problem is that a magnetic reversal could be disastrous.
