This video reiterates many of the issues that I point out in Not by Fire but by Ice and Magnetic Reversals and Evolutionary Leaps.
Right now, magnetic north has been moving south much faster than anticipated, triggering concerns that earth’s magnetic field could get weaker or even reverse, says the host.
The earth’s magnetic field, called the magnetosphere, plays a crucial role in making earth a habitable planet, she explains. “It wards off much of space’s harmful radiation like cosmic rays, acting like an essential protective cloak around the earth.”
“A weakened magnetosphere means many things:”
• “The northern lights will be visible in new parts of the world, for a start.”
• “All of our satellites would need to be fortified against extra radiation or we risk them getting totally fried by space weather, like solar wind.”
• “Electronics here on earth would be extremely vulnerable to interference and destruction by space radiation too, like our power grids.”
• “And that’s not even mentioning the human health effects by being exposed to much higher degrees of radiation from space, which, let me tell you, are not great.”
It’s also not mentioning the possibility, I might add, that magnetic reversals can lead to evolutionary leaps (via mutations caused by the radiation), increased volcanic activity (both underwater and above water), increased earthquake activity, bigger floods, bigger snowstorms, lowered sea levels, and perhaps the most dangerous of all, ice ages.
