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
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.

Cloud physics is the study of the physical processes that lead to the formation, evolution and impacts of atmospheric clouds, including precipitation and cloud radiative effects.

…and these changes then further affect the Earth's energy balance. On their own, clouds are already an important part of the climate system, as they consist of liquid droplets and ice particles, which absorb infrared radiation and reflect visible solar radiation. Clouds at low altitudes have a stronger cooling effect, and those at high altitudes…
