What is an appropriate antonym for "genesis"?

Dissipation is the first possibility to mind, especially if you are talking about very IMMORAL weather. Probably caused by climate-change. =] http://en.wikipedia.org/wiki/Dissipation

Resolution.

Late PS: Perhaps because I'm a bit highbrow (note elevated snoot!) I tend to hate highbrow terms. Familiarity breeds contempt. So how about a good knuckle-dragging Neanderthal term instead? Like, um... fizzle.. Hurricane Gonzalo will fizzle somewhere between Bermuda and Newfoundland... fo'shizzle it'll fizzle (whoa! poetic!)

It seems to me that when "genesis" is used to describe the earth's creation, that its antonym isn't about the earth's death. It's about its "reconfiguration" or "recycling" in the cosmos.

I'm seeing several reference to hurricane dissipation: The dissipation of Hurricane Katrina, and the "Hurricane Formation, Movement, and Dissipation."

Before it dissipates, the hurricane will decay: "Hurricane Decay: Demise of a Hurricane." There's another word: demise.

Lysis seems to carry a connotation of cell death in the realm of biology. It seems like a metaphorical stretch to go from cell death to hurricane death, because one is very small and is literally dying; the other is very big and figuratively dying.

Was looking for a similar answer. Here are the words I've narrowed down to:

-terminus -coda -quietus

Hope one of those finds its way to your use.
