In Which Pretty Pictures Panic The Pea-Brained

Crop circles make me smile, yes, and admire
The ingenuity of the artistes
Who make them. I have tried, but quickly tire;
To push down crops is hard work, and I cease
Long ere my handiwork takes on the scope
Of such as these, whose dire significance
Would seem all doomsday sayers' greatest hope.
Upon these wacky claims I look askance.
Ultraterrestrials (to use the late
John Keel's term), if they really did care
Enough to warn us of a baneful date
Would, I feel sure, find a clear way to share.
And yeah, the hole in our magnetosphere
And CME threat are explained right here.
