I guess, without internal lava, the insulated guts of our planet would grow colder and colder as it is isolated from the heat of the sun. So, that coldness would begin to freeze or cool the surface of the globe or at least attempt to. So, the atmosphere, the air, may act as a blanket, meaning it gets colder up in the mountains, even as you move closer to the sun.

I've always assumed that things are warmer as you move closer to sea level. I've never thought about what the temperature of the inner organs of the earth. It's true that climate change is partly due to geoengineering, Big Pharma, Monsanto, Microsoft, Bill Gates, Vaccines, Bio Weapons, etc. However, at the same time, climate and weather is mostly dependent on the sun and secondarily dependent on volcano activity, perhaps. CO2 helps the earth. Humans are carbon based. We emit carbon. The trees breath the CO2 and turn that into oxygen. We can notice climate cycles that repeat daily, monthly, quarterly (each season), annually, every decade, fifty years, century, 500 years, etc. So, climate can go up and down during droughts, ice ages, global warming, etc.
