“The fossil record shows no drastic changes in plant or animal life,” says this article on SOTT. I beg to differ.
“Many doomsday theorists suggest that a magnetic reversal could lead to Earth’s destruction,” the article continues. “But would there be any dramatic effects?”
“The answer, from the geologic and fossil records we have from hundreds of past magnetic polarity reversals, seems to be ‘no.’ During the last major reversal about 780,000 years ago, at the Brunhes-Matuyama reversal, “the fossil record shows no drastic changes in plant or animal life. Deep ocean sediment cores from this period also indicate no changes in glacial activity.”
I beg to differ on almost all counts.
