Global Environmental Crisis of 42,000 Years Ago Linked to Breakdown in Earth’s Magnetic Field

Scientists understand that Earth's magnetic field has flipped its polarity many times over the millennia. Many doomsday theorists have tried to take this natural geological occurrence and suggest it could lead to Earth's destruction. But really, would there be any dramatic effects? Well, yes -- The temporary breakdown of Earth’s magnetic field 42,000 years ago sparked major climate shifts that led to global environmental change and mass extinctions, according to a new international study co-led by the University of New South Wales (UNSW) Sydney and the South Australian Museum. This dramatic turning point in Earth’s history – laced with electrical storms, widespread auroras, and cosmic radiation – was triggered by the reversal of Earth’s magnetic poles and changing solar winds. While the magnetic poles often wander, some scientists are particularly concerned about the current rapid movement of the north magnetic pole across the Northern Hemisphere. The speed – along with the weakening of Earth’s magnetic field by around nine percent in the past 170 years – could indicate an upcoming reversal. If a similar event happened today, the consequences would be huge for modern society. Beyond the obvious dangers like sharp increases in UV levels affecting all land-based life forms, a flood of incoming cosmic radiation would destroy our electric power grids and satellite networks.
