Is There A Magnetic Pole Reversal In Our Future ???

According to this report, the earth's magnetic poles flip more frequently than previously thought - every 200,000 years or so:

Data collected by the European Space Agency's Swarm satellite array reveals the Earth's magnetic field has recently been weakening at a rate of around five per cent per decade. The field does change all the time, but a rate of five per cent century is more normal, leading some to speculate a pole reversal may be imminent.

It is unclear precisely what would happen if the field weakens greatly or disappears for a time during a reversal. However, scientists believe power grids and communications systems are potentially at risk.

Should the field disappear for a while, we're at risk, too.

I wonder what will happen to all those creatures whose sense of direction is dependent on the field? Will they be lost for a while?
