NASA: Earth’s magnetic poles are ‘switching’ with catastrophic consequences for humanity
THE Earth could be left powerless to defend against blasts of solar radiation from the Sun for up to 200 YEARS, leaving us at risk from skin cancer and worldwide electronic communication blackouts, NASA scientists have warned.

Climate researchers believe we are heading towards a reversal of the planet's magnetic field, an event that has happened before and has been attributed to wiping out the Neanderthal species.
Bruce Jakosky, MAVEN principal investigator at the University of Colorado, Boulder, said when the switch does take place, the Earth's magnetic field which prevents the Sun's dangerous radiation getting through, would be neutralised for around 200 years.
He revealed the detail during an historic announcement about how Mars lost 99% of its atmosphere and its oceans that could have housed early life.
Mr Jakosky explained that Mars had been blasted by solar winds, which had stripped it of its atmosphere, for billions of years since the beginnings of our solar system.
He said: "When the polar shift happens the Earth will have no magnetic field for about 200 years."
During that time the Sun's solar blasts are expected to strip away at our atmosphere as they did on Mars billions of years ago.
But he thankfully added that 200 years would not be long enough for the Sun to significantly reduce the atmosphere for life to die out.
