Although the pottery data points are about 500 years apart, we can see that the decline has picked up speed over the last 1,000 years. Direct daily and yearly measurements of magnetic field strength have now been determined from ship logs beginning in 1590 A.D., and from sensitive instruments since 1840, and tell a slightly different but nevertheless consistent tale. The current field did not change very much between 1590 and 1840, but since 1840 it has started a significant decline, by about 5 percent per century. Whether the next major reversal happens in 100 years or 1,000 years we still cant tell for certain, but the effects will probably only impact migratory birds, whales and certain kinds of bacteria that navigate with the magnetic field. You and I will not notice much, except aurora in odd places of the world where they have not been sighted before. Ice-core data from Greenland shows that the Laschamp Event caused more cosmic rays to reach the atmosphere, but there is no evidence of species extinctions or other biological effects. Interesting timing for release of this article. Oh and weve already had aurora in odd places and fish and migratory bird disturbances. To say that this has no effect on us is totally false.
