hardly it is just cycling though it natural progression as has been for

The problem is we could be much more vulnerable to the radiation from
solar storms during the time period that the earth's magnetic field is
reversing. No one knows for sure how long this takes. It could be months
or years. There will also be a higher risk of skin cancer during the
reversal period and compasses will be almost useless. Fortunately we
have alternatives to the compass these days.
