I was thinking of using a giant toroidal lens around the entire scene. 
Nearby objects would lie inside the torus and would not be refracted. 
Distant objects would lie outside the torus and would be refracted. Not 
sure what exact shape the lens should be. My optics is a bit rusty from 
high school...

A mirror instead of a lens might work and might even render faster, but 
I'd have to make sure most of my scene is not reflected. I would want 
the clouds to appear in the mirror, and the mirroring would probably be 
noticeable at the edge.
