The first set of high-resolution results from ESA's three-satellite Swarm constellation reveals the most recent changes in the magnetic field that protects our planet.

Launched in November 2013, Swarm is providing unprecedented insights into the complex workings of Earth's magnetic field, which safeguards us from the bombarding cosmic radiation and charged particles.

Measurements made over the past six months confirm the general trend of the field's weakening, with the most dramatic declines over the Western Hemisphere.

But in other areas, such as the southern Indian Ocean, the magnetic field has strengthened since January.

The latest measurements also confirm the movement of magnetic North towards Siberia.

These changes are based on the magnetic signals stemming from Earth's core. Over the coming months, scientists will analyse the data to unravel the magnetic contributions from other sources, namely the mantle, crust, oceans, ionosphere and magnetosphere.

So not only will people be affected by changing climates, but also magnetic fields? Life is going to get real tough for some people.

Perhaps the title should read:

"Most Recent Changes in Earth's Magnetic Field; Sources [b]to be[\b] Analyzed."

Increased odds of power grid disruption would appear to be the main concern. http://www.scientificamerican.com/ar...than-expected/

Here is a video on the near miss in 2012. We dodged the bullet by just one week.
