And the most recent event had much higher effect than expected.

BTW, the Erf's magnetic field strength dropped 10% 1800- 2000, 5% in the decade between 2000 and 2010, and there doesn't appear to be any available data for the last decade.

I'm certain someone knows just how much, but for some strange reason it isn't being reported to mere mortals.

And the most recent event had much higher effect than expected based on the 2010 field strength!

I wonder why?

Yeah, gave up looking for that.

I think the scientists that did this research are sleeping with the fishes.

The Earth’s magnetic field actually reverses on a fairly regular basis. We are at a point where it is switching again. Instead of all the charged particles getting funneled to the poles it hits the atmosphere everywhere when the field is at the zero point.

Erf??? Wtf is a erf?

Or do u mean earth?
Check a dictionary for proper pronunciation.
