Prove it. What did you read that tells you that a minor fluctuation in the Earths magnetic field , to the tune of double what we have to none at all, holds any biological risk. Remember, that's what this is about... you claimed that the changes int he Earth's magnetic field are dangerous. Show how a paper dealing with magnetic field strengths tens of thousands of times *greater* than the Earth's are relevant here.

(Note for those playing along: Earth's magnetic field is on the order of 0.5 Gauss. Typical MRI's are from 0.5 to 2.0 Tesla in strength. 1 Tesla = 10,000 Gauss.)

What you are basically arguing is that since if I shine a laser at you that is ten thousand times more wattage per unit area than bright sunlight, and it causes damage... then you risk damage going into the dark.

So, again, show that you ahve read *and* *understood*. What did the report say that leads you to believe that if the Earth's magnetic field shuts down, that that alone will cause biological harm?
