We actually get most our warmth from the radiation leaking from Earths core, and we need that blanket of green house gasses to keep the heat. You are right though, that drastic variations are due to changes in the sun. Just wanted to point out that the sun alone is not keeping the planet warm enough for us to inhabit. If our core ever solidified we are all SOL.
Nobody knows what’s down there. It is theorized molten iron because they needed a reason for the magnetic field which it turns out also comes from the sun.

Seriously. The one and only source of energy for our entire planet determines the global temperature? Wow, amazing.
