I find it difficult to believe something of this magnitude will not have some major impacts on the surface. Even thought this has occurred many times, not much has been done what impact magnetic shifts have had on life on the surface. A lessening magnetic field does cause a degradation in the ozone. Something Sierra Club crazies and save the snail darter seem to not mention in debates about global warming. During the no magnetic field period which will last over a 10,000 years some of the earth's atmosphere is going to be stripped away. Genetic mutations will be greatly increased. Impact on weather, Teutonic plate movements, volcanic activity seems to be a big unknown. Humanity will survive, but not necessarily civilization. Ad to the above, an overdue ice age that it is going to be a very interesting time for future generations. I suspect, if they will be dumbfounded at our concern over SUVs, hair spray and oil spills if the impacts of the above events are major.
