Quite true, although many types of clouds are warming. But cooling clouds and cooling aerosols are quite doable and cheap. The global warming alarmists refuse to admit that their models are inadequate even though if they were adequate the cloud adjustments could be modeled and tailored to meet a desired cooling goal.
Warming clouds are very useful too. We want cooling at the poles and equator and warming during winter in the latitudes we live and grow our food in.
Clouds are somewhat local so the desired climate can be managed locally without the need for a world government. Some like it hot and some like it cold. Climate control is not the vehicle to a super invasive government the left hopes it is.
Snow might be considered a type of solid cloud because it also acts as both blanket and reflector and is made of fresh water. Clouds, fog, and snow are the most important gifts from nature we have for actively managing the climate.
