Missing geomagnetic flips suggest Earth’s past is dangerously incomplete
A team led by Japan’s National Institute of Polar Research has identified four time windows in the last 160 million years where Earth’s record of magnetic pole reversals appears to be missing entries.
During a brief but dramatic chapter in Earth's history about 41,000 years ago, the planet’s magnetic field nearly collapsed. What followed was a cascade of environmental and biological changes that ...
