Forget global warming, worry about the MAGNETOSPHERE: Earth's
magnetic field is collapsing and it could affect the climate and wipe
out power grids
- Earth's magnetic field has weakened by 15 per cent over the last 200 years
- Could be a sign that the planet's north and south poles are about to flip
- If this happens, solar winds could punch holes into the Earth's ozone layer
- This could damage power grids, affect weather and increase cancer rates
- Evidence of flip happening in the past has been uncovered in pottery
- As the magnetic shield weakens, the spectacle of an aurora would be visible every night all over the Earth

Deep within the Earth, a
fierce molten core is generating a magnetic field capable of defending
our planet against devastating solar winds.
The
protective field extends thousands of miles into space and its
magnetism affects everything from global communication to animal
migration and weather patterns.
But
this magnetic field, so important to life on Earth, has weakened by 15
per cent over the last 200 years. And this, scientists claim, could be a
sign that the Earth’s poles are about to flip.
