Our planet is restless, and its poles are wandering. Of course, the geographic north pole is in the same place it always was, but its magnetic counterpart – indicated by the N on any compass – is roaming towards Siberia at record-breaking speeds that scientists don’t fully comprehend.
It’s worth stating that while the pace is remarkable, the movement itself isn’t. The magnetic north pole is never truly stationary, owing to fluctuations in the flow of molten iron within the core of our planet, which affect how Earth’s magnetic field behaves.
“Since its first formal discovery in 1831, the north magnetic pole has travelled around 1,400 miles (2,250 km),” the NOAA’s National Centres for Environmental Information (NCEI) explains on its website.
“This wandering has been generally quite slow, allowing scientists to keep track of its position fairly easily.”
That slow wander has quickened of late. In recent decades, the magnetic north pole accelerated to an average speed of 55 kilometres (34 miles) per year.
While it may seem obvious that a good hike through a forest or up a mountain can cleanse your mind, body, and soul, science is now discovering that hiking can actually change your brain… for the better!
Aside from the almost instant feeling of calm and contentment that accompanies time outdoors, hiking in nature can reduce rumination. Many of us often find ourselves consumed by negative thoughts, which takes us out of the enjoyment of the moment at best and leads us down a path to depression and anxiety at worst. But a recent study published in Proceedings of the National Academy of Sciences found that spending time in nature decreases these obsessive, negative thoughts by a significant margin. Leer Más
