Earth’s Magnetic Field is Shifting and Geologists Don’t Know Why
Something strange is happening with the Earth’s magnetic field and scientists are unsure why, according to a recent paper published in the journal Nature. A consortium of geologists in charge of the World Magnetic Model is having trouble keeping track of the planet’s magnetic north pole as it rapidly shifts from Canada to Northern Siberia.
Scientists updated Earth’s magnetic model in 2015, which is used for some pretty important things, including shipping navigation and GPS on smartphones. Their model was intended to last for at least five years, but due to the recent unexpected swing, it became outdated at some point in early 2018 and is now in need of adjustment.
“The error is increasing all the time,” said Arnaud Chulliat, a geomagnetist at the University of Colorado Boulder and the National Oceanic and Atmospheric Administration’s National Centers for Environmental Information.
Scientists say this shift is being driven by liquid iron sloshing around in the planet’s core, a natural process, but one that can vary as the flow changes. Over the past 20 million years, Earth’s magnetic field has consistently experienced a complete pole reversal – usually every 200-300,000 years.
At the moment, we’re long overdue for one of these events, with the last reversal having occurred 781,000 years ago. No one is quite sure what the consequences will be on modern infrastructure when and if that reversal happens. Many take ease in the fact that pole reversals have occurred hundreds of times in the planet’s history without catastrophe, but again, the effect on modern technology remains unknown.
Some scientists have pointed to this shift as a potential culprit in a slew of recent dolphin and whale beachings as well as other unexpected animal die-offs. It’s believed the planet’s natural magnetic field is necessary to some of these animals’ navigation when traveling and communicating over great distances underwater. One NASA scientist is currently looking into this potential connection.
In 2016, a larger-than-usual magnetic pulse shot up from South America, which scientists believe played a role in furthering the recent shift. However, they’re still unsure whether it will continue on this course, or even what will happen at all.
Could we be on the precipice of a massive geomagnetic reversal, or is this just due to slightly-more-anomalous-than-usual activity in the Earth’s core? And what’s even more pressing – what kind of effects is this having on us?

How Can We Imbue Artificial Intelligence With Compassion?
Can artificial intelligence be designed to be compassionate?
Given the ever-increasing pace of development in the world of artificial intelligence, many scientists and researchers are calling for more rigorous regulation to avoid potentially disastrous consequences. And the idea of building positive human values, such as compassion into AI design is quickly gaining momentum
Gregg Braden is a former senior computer systems designer, best-selling author, and leader in the fields of science and spirituality.
“The topic of compassion in artificial intelligence, while in many circles people have never heard of it, in the circles of science and technology it’s a hot topic,” Braden said. “In one way or another, this topic is going to touch each of our lives, and it’s going to happen faster than we have been led to believe. Humankind is at a crossroads right now, for the first time in the history of our species, where we have the technology to support the philosophy of the way we think about ourselves and our relationship to the world around us, to software, to robots, to artificial intelligence, (and) to machine intelligence.”
“The development of AI is moving at an exponential rate, it’s no longer linear, and it’s not regulated,” he said. “We’re talking about AI that is going to be running huge national and international systems of electricity, power, energy, water, food, and weapons systems that are the reality of our lives today. So, if we’re going to allow artificial intelligence to play a vital role in our lives, we want that intelligence to be more than intelligent — we want it to be smart, we want it to be intuitive, and we want it to be compassionate, as it makes the decisions that affect all of our lives.”
