“ Magnetic disaster ‘that wiped out Neanderthals’ is due a repeat
The world reached a turning point towards the tail end of the Stone Age. In Europe our closest evolutionary cousins, the Neanderthals, vanished while in Australia every animal larger than a kangaroo disappeared. Our species displayed a creative explosion of cave art.
A new study argues that this can be linked to one event — a sudden collapse of the Earth’s magnetic field, which left the planet vulnerable to a blistering surge of cosmic radiation.
The research, published in the journal Science, points out that we are overdue a repeat. It looks at the most recent reversal of our magnetic field, which surrounds the world like an invisible balloon, defending us from a barrage of deadly particles emitted by the sun.
About 42,000 years ago the poles flipped and magnetic north essentially became south. The magnetic field, generated by the churning of molten iron in Earth’s outer core, faded to 6 per cent of its usual strength. The sun began to emit intense bursts of radiation.“

Better get more fridge magnets, or even better - get lead padded fridge before it’s too la
