iflscience is sometimes interesting, but often (as here) ludicrously sensationalistic clickbait.<p>There's a couple major misrepresentations here; while 450,000 is an often-stated average, its important to note that there is no evidence of periodicity, so the idea that the planet would be "overdue" for a reversal is misguided.<p>The other cited evidence for an imminent shift is drop in the strength of the Earth's magnetic fields, but major variations in field strength appear without pole reversals.<p>The actual BBC Earth article [0] that IFLS gives a "hat tip" to as its source is <i>not</i> about an imminent pole reversal, but about research that suggests the average frequency of pole shifts has increased over time, and discussion of the possible mechanisms for that, mentioning it in passing in one sentence near the end of the article as something that some people <i>speculate</i> based on the recent weakening of the magnetic field.<p>[0] <a href="http://www.bbc.com/earth/story/20141110-earths-magnetic-field-flips-more?ocid=fbert" rel="nofollow">http://www.bbc.com/earth/story/20141110-earths-magnetic-fiel...</a>
