I am very confused right now. I am making an Earth. The scene has two layers, atmosphere and ground/clouds. Rendering them individually gives me the results I want for each layer. Specifically, here is the atmosphere layer:
But when I render both layers together I get something hideous like this:
Do you see that hideous fog on the image? That is actually a mirror image of Africa and Europe, somehow being reflected onto the fresnel. I have no idea what is causing this, and would greatly appreciate any insight.

UPDATE1 Turning diffuse bounces down to 0 worked. I am not happy with this solution.
UPDATE2 Keeping diffuse on and turning glossy bounces does NOT work. Neither does turning off the "Glossy" option under Ray Visibility
in the Object
tab. Again, I am not happy with this solution.
