“Reversals are generated in the deepest parts of the Earth’s interior, but the effects manifest themselves all the way through the Earth and especially at the Earth’s surface and in the atmosphere,” said Brad Singer, study author and University of Wisconsin-Madison geologist. “Unless you have a complete, accurate and high-resolution record of what a field reversal really is like at the surface of the Earth, it’s difficult to even discuss what the mechanics of generating a reversal are.”

Earth’s Magnetic Field Reversal Took Three Times Longer Than Thought
In their paper published today in Science Advances, Brad Singer of the University of Wisconsin–Madison and his colleagues calculate that Earth’s last magnetic field reversal took roughly 22,000 years.
Earth’s Magnetic Field Went Completely Haywire During Last Reversal and Took 22,000 Years to Get Back to Normal
In a study published in Science Advances, a team led by Brad Singer, from the University of Wisconsin-Madison, looked at lava flows to trace back the last major reversal and find out how long it took.
Earth’s Magnetic Field Could Take Longer to Flip Than Previously Thought
“[Polarity reversal] is one of the few geophysical phenomena that is truly global,” says Brad Singer, professor of geoscience at the University of Wisconsin–Madison and lead author of the study.
Earth’s Last Magnetic-Pole Flip Took Much Longer Than We Thought
“We found that the last reversal was more complex, and initiated within the Earth’s outer core earlier, than previously thought,” lead study author Bradley Singer, a professor of geoscience at the University of Wisconsin-Madison, told Space.com.
UW study: Major surgery’s impact on brain is smaller than feared
Robert Sanders, UW assistant professor of anesthesiology, said on average people’s cognition is “pretty much the same” after a major operation as compared to before, according to a study he authored that was recently published in the British Medical Journal.
Earth’s last magnetic field reversal took far longer than once thought
New work from University of Wisconsin-Madison geologist Brad Singer and his colleagues finds that the most recent field reversal, some 770,000 years ago, took at least 22,000 years to complete. That’s several times longer than previously thought, and the results further call into question controversial findings that some reversals could occur within a human lifetime.
