I believe that the answer is "yes" based on what I read somewhere on SkS. Unfortunately, I cannot find the statement that I recall reading. Can someone help me out on this?

Well, to some extent: If you increase the overall temperature of the atmosphere, the "scale height" (characteristic distance scale) will expand accordingly. So everything gets spaced out a bit.

If I recall correctly, the statement I read was written by John Cook and it had to do with either the height of the toposphere or the stratosphere increasing per satellite measurement.

The rising tropopause is mentioned In the Guide, I don't remember any post about it. As far as I remember we never talked about the expansion of the whole atmosphere.

I think you're talking about the tropopause (boundary between troposphere and stratosphere), which is rising.

Thanks.  

If the tropopause is rising, is the height of the stratosphere declining by a like amount?

You mean the upper boundary of the stratosphere?  Not as far as I know, but I'm not sure.

The mesosphere is also contracting.

How were the "band-widths" of the layers of the atmosphere computed prior to the advent of satellites?
