Re: “But if the earth radiated back into space less than the amount of it got, wouldn't the earth's temperature climb higher every day until water boiled and earth became more like Venus?”Everything not in equilibrium is changing. If the Earth were not in equilibrium with the sun, it would adjust until a new equilibrium was found. It wouldn't necessarily get hot like Venus. It could just be a matter of a collision with a comet. Earth would initially radiate MORE of the sun's light away until the clouds cleared, then radiate away a bit less until a new equilibrium appropriate for the cold mass it had gained.

The Earth receives more from the sun than just its energy. What about its gravity? That gives the planet its orbit and its trajectory. What about its emissions? They undoubtedly play a huge role in the changes to DNA that have taken us from single-celled organisms to what we are today and may become in the future (unless science does that first.) It's a pretty important blob of heat and light and mass and warped space-time.

Anticipating you are going to say something like "warmth" or "light", I am going to ask another question:

How much of the warmth or light the earth gets each day does it radiate back into space?

But if the earth radiated back into space less than the amount of it got, wouldn't the earth's temperature climb higher every day until water boiled and earth became more like Venus?
