Cloud albedo is a measure of the albedo or reflectivity of a cloud. Clouds regulate the amount of solar radiation absorbed by a planet and its solar surface irradiance. Generally, increased cloud cove

Increased cloud droplet concentration and albedo due to aerosol effect
A cloud feedback is a climate change feedback where some aspects of cloud characteristics are altered due to climate change, and these changes then further affect the Earth's energy balance. On their

…cause atmospheric instability that influences the hydrological cycle, weather patterns, and atmospheric circulation. These effects are parameterized by cloud radiative forcing, a measure of short-wave and long-wave radiation in relation to cloud cover. The Earth Radiation Budget Experiment demonstrated that small variations…
High clouds in the tropics
Tropical clouds are known to have a cooling effect, but it is uncertain whether it would become stronger or weaker in the future
Air pollution, including from large-scale land clearing, has substantially increased the presence of aerosols in the atmosphere when compared to the preindustrial background levels. Different types of particles have different effects, and there is a variety of interactions in different atmospheric layers. Overall, they provide cooling, but complexity makes the exact strength of cooling very difficult to estimate.
