Doesn't CO2 (and H2O vapor for that matter) make Earth's surface cooler and summers cooler?

Correct me if I'm wrong, but don't greenhouse gases soak up the heat from Earth's surface and distribute the heat from the surface throughout the troposphere so that it's warmest at the bottom and coolest at the top and, without greenhouse gases, surface temperature during the day would be like 120 C like on the Moon and only a few feet off the ground during the day would be like -40 C like on the Moon? So how does greenhouse gases increase temperature on Earth's surface as the greenhouse effect theory goes?

Curiosity measured Mars temperature as high as 6 C during the day and as low as -70 C at night, at a place near the equator. It seems, because Mars has less greenhouse effect, Mars's temperature a few feet off the ground is much less regulated as compared to Earth, where day time high and night time low are typically only a few degrees C from each other.

The atmosphere does what you describe. There is no special subset of atmospheric gases that have magical "greenhouse" superpowers.

There's a reason the Stefan-Boltzmann equation has no variables for atmospheric composition. It just doesn't matter.

If Venus were a black body it would have a much much lower temperature than what we found there.- tmiddles

Ceist - I couldn't agree with you more. But when money and religion are involved, and there are people who value them above all else, then the lies begin. - trafn

You are completely misunderstanding their use of the word "accumulation"! - Climate Scientist.

The Stefan-Boltzman equation doesn't come up with the correct temperature if greenhouse gases are not considered - Hank

:*sigh* Not the "raw data" crap. - Leafsdude

IB STILL hasn't explained what Planck's Law means. Just more hand waving that it applies to everything and more asserting that the greenhouse effect 'violates' it.- Ceist
