If CO2 and H2O trap heat, then why is Earth not warmer than its moon?

You really can't compare the Earth's atmosphere to the Moon's when the Moon doesn't have one.

But the Moon's surface temperature swings in extreme, depending on if the Sun is up or not.

-----------------------

The Earth is warmer than the moon. At night the moon is something like -300 degrees, at day it's baking hot, the average is still colder than the Earth.

The temperature of the Moon one meter down is a constant minus 35C (probably a good average), pretty damn cold

due to "atmospheric pressure" ? clearly, you slept through science class. Jupiter has more pressure than earth and is colder.

You start with a wrong assumption.

You modify it with a mistaken correction.

Have you ever bothered to check what you're saying against reality?

Our moon has NO atmosphere, so with your "Additional Details", has not your question become a point of being useless as a question?

CO2 & H2O regulate heat loss. 'trapping' is a rather inaccurate & highly misleading term.

And why would I believe you?
