If you think you smell sewer gas in your bathroom, it could be that a sewage blockage is in your pipes, causing the sewage to back up in the lines.

What causes greenhouse gasses? I dont know why do you even ask?
It could be that the condesate drain line has been connected to the wastewater/blackwater stack. The trap (hopefully installed) preventing sewer gas from moving up the condensate line may have dried out. If dry, sewer gasses are no longer blocked by the hydraulic seal... resulting in a nasty smell when the unit is turned on and the fan kicks in. Just a thought.
No, something more basic is the cause of that.
Two possible answers - tree roots growing into the pipe in your yard or tampons being flushed down your toilet.
When magma is underground it is under enormous pressure, which causes the gasses to dissolve in the magma. As the magma rises pressure decreases and the gasses come out of solution. All gasses expand when decompressed.
