    which it does on a regular basis during natural field reversals. The geologists imply its a very sharp transition like a century or less from normal field, no field, reversed field. If you donate to the UN fund that pays for the solar shield, you get shielded when the time comes. If not, well... life does survive reversals, but its likely not fun.
