Drop That Paper And Back Slowly Away

What, bunnies ask, do zombies wanting to eat your brains have to do with the Stadium Wave? Well consider, the Weasel’s take on Wyatt and Curry’s Role for Eurasian Arctic shelf sea ice in a secularly varying hemispheric climate signal during the 20 th century .  Eli’s friend actually reads the paper and notices several things.  First, the waves, that W&C claim to be displaced from one another in several different climate indicators (see the figure below for a quick look, read the link to Stoat for more details) are the result of massive filtering of the AMO, PDO, etc.  To get an idea of how much smoothing, compare the two figures below).  Second, all of the signals were normalized in the figure displayed by W&C, even though most of them had little power in the frequency pass band.  Stoat goes on to show that ————————————————— Removing this, along with the other three that have essentially no in-band variance, leaves me with this crudely retouched version of their figure 2 a. Its now much less obviously a wave; its just three (four really, but two essentially overlay) different lines filtered to within an inch of their lives into a 60-year-ish band.
