Each day when our part of Earth rotates into darkness, the temperature drops 30 to 40 degrees. If all of that heat from the Sun can escape in just a few hours of darkness, there is no way that any amount of human activity induced heat could not also escape within mere seconds.

The issue is not about "heat from human activity", but rather the ability of CO2 to act as an insulating blanket over the planet! Just to give you a bit to think about, the concentration of CO2 in the atmosphere has grown by ~1/3 since the dawn of the industrial revolution. Now that may not seem like a big deal, but can you imagine adding 1/3 more insulation in your attic (assuming you heat your house) and not reducing the output of the furnace.

simple logic shows that any greenhouse agent (clouds, CO2, CH4, etc) would result in positive net gain.

For example suppose clouds reflect 10% of heat. They will reduce sun induced heating by 10% during day (12hr) and decrease cooling by 10% during day and night (24hr).
10% * 12/24 = 5%
10% * 24/24 = 10%
5% < 10%

Its accepted that low white clouds provide negative forcing as in Svenmarks study.
