Theories of Jupiter Cloud Belt Disappearance

On Facebook, Matt blames Earth's global warming for the disappearance of the Jupiter Cloud Belt. The data, however, makes me skeptical:
"The SEB fades at irregular intervals, most recently in 1973-75, 1989-90, 1993, 2007, 2010," said John Rogers, director of the British Astronomical Association's Jupiter Section. "The 2007 fading was terminated rather early, but in the other years, the SEB was almost absent, as at present."
Contra Matt, I would point to the fact that three of the first four SEB fades occurred during the year of a NBER business cycle peak: 1973, 1990, and 2007. Whether the Jupiter cloud belt is a lagging or leading indicator, I cannot be sure. Regardless, I think the writing is on the wall (er, Jupiter atmosphere) that we are about to experience a double-dip recession.

Being an Oakland A's fan, those dates are also fairly coincident with their appearances in the postseason. I'll bet accordingly.

Perhaps, but then again maybe the A's performance is a indicator of business cycle peaks?
