'True polar wander' and Earth's ice ages

Rice University geophysicists have determined Earth shifted relative to its spin axis within the past 12 million years, which caused Greenland to move far enough toward the north pole to kick off the ice age that began about 3.2 million years ago. The study is based...

Research helps explain ongoing changes in geomagnetic field

Scientists from the University of Rochester used new data from sites in southern Africa to help explain recent and ongoing changes in Earth's magnetic field, best expressed by a deepening area of low field called the South Atlantic Anomaly. Their research...

Earth's magnetic flip and what it means for human civilization

Earth's magnetic field has flipped many times throughout history and is now on its way toward another reversal. While the topic was highly controversial in the 20th century, numerous studies over the past decades have proven this as a fact, that it's...

A giant lava lamp inside the Earth might be flipping the planet’s magnetic field

If you could travel back in time 41 000 years to the last ice age, your compass would point south instead of north. That’s because for a period of a few hundred years, the Earth’s magnetic field was reversed. Magnetic reversals have happened repeatedly...

Why the Earth’s magnetic poles could be about to swap places – and how it would affect us

The Earth’s magnetic field surrounds our planet like an invisible force field – protecting life from harmful solar radiation by deflecting charged particles away. Far from being constant, this field is continuously changing. Indeed, our planet’s...

Earth's magnetic field changes mapped in detail

A group of experts utilized the data collected by the ESA's SWARM satellites to show how the magnetic field is pulsating, where it's weakening and strengthening, and how fast these changes occur. For the first time, experts have mapped both the changes...

Widespread extinction after Earth's hyperactive magnetic field reversals

Research results of the new study indicate the rapid reversals of Earth's magnetic field which occurred about 550 million years ago is responsible for destroying a huge portion of the ozone layer. This destruction has, in turn, allowed a higher concentration of...

Scientists allay fears of Geomagnetic Pole Shift in the near future

A group of researchers have studied ancient volcanic rocks to conclude that Earth's magnetic field is a long time away from "flipping" even if the magnetic field's intensity is reducing fairly fast. This is because Earth's current magnetic...

3.3-million-year-old stone tools found in Kenya

Scientists working in the desert badlands of northwestern Kenya have found stone tools dating back 3.3 million years, long before the advent of modern humans, and by far the oldest such artifacts yet discovered. The tools, whose makers may or may not have been some

Earth’s magnetic field can flip in less than 100 years, new study

It is known that Earth’s magnetic field has flipped many times throughout the planet’s history. Its dipole magnetic field remains about the same intensity for thousands to millions of years, but for incompletely known reasons it occasionally weakens (such is
