Clouds Albedo Greenhouse Debate

Discussions center on whether increased clouds or water vapor from a device would cool Earth by boosting albedo and reflecting sunlight, or warm it via enhanced greenhouse effects and reduced heat escape.

lets say it works, and makes the clouds. the clouds which rain down, and cool the surface. now your temperature differential is gone, no?

Isn't that supposed to cool the planet. The other way round is called err, normal ?

Wouldn't extra water vapor end up as clouds and reflect sunlight away from earth?

Yep, less heat making it to the upper atmosphere.

wouldn't large scale usage of a device like this essentially increase the planetary albedo and help fight climate change? especially if you just skip the "environmental heat transfer" part

The impact on global warming is the same.

Wait, doesn't that mean less greenhouse effect?

andrewmutz Oct 16, 2023 View on HN

Doesnt increasing earths albedo actually cause heat to be reflected from the earth (and lower temperatures)?

Isn't increasing the albedo cooling the planet down?

less human = less greenhouse gas emissionsless greenhouse gas emissions = less greenhouse gasless greenhouse gas = cooler watersSeems the problem is eventually self correcting.
