Did this mostly to learn how to do a transparent dome... this effort used:

 difference {

    sphere { <0,0,0>, 1
       texture{ pigment{ rgbf <0.98, 0.98, 0.98, 0.9> }
       finish { ambient 0.1 diffuse 0.1 reflection 0.2
       specular 0.8 roughness 0.0003 phong 1 phong_size 400}
               } // end of texture

          scale<130,70,130>  rotate<0,0,0>  translate<0,0,0>
       }  // end of sphere -----------------------------------

        sphere { <0,0,0>, .999
           texture{ pigment{ rgbf <0.98, 0.98, 0.98, 0.9> }
           finish { ambient 0.1 diffuse 0.1 reflection 0.2
           specular 0.8 roughness 0.0003 phong 1 phong_size 400}
               } // end of texture

          scale<130,70,130>  rotate<0,0,0>  translate<0,0,0>
       }  // end of sphere -----------------
}

Rotate the city. I don't want to see right through it, that makes it look
odd, makes it look much smalller. Also, if it were me, I would make the
ground/globe an isosurface, so you could give it a little geography.  It is
*very* flat.
You might also play around with camera angles; I think you could find a
quite dramatic one.
A nice image.

Why did you repeat the whole texture and finish?
A beter way to do the same:
difference{
	sphere{0,1}
	sphere{0,0.999}
	texture{pigment{rgbf<0.98,0.98,0.98,0.9>}
	finish{ambient 0.1 diffuse 0.1 reflection{0.01, 0.22 fresnel}
	specular 0.8 roughness 0.0003}//end of finish
	}//end of texture
	interior{ior 1.5}//average value for glass
	scale{130,70,130>
}//end of dome
Shorter and less error prone. It also use less memory.
