Cloud formation and climate change and global warming. Some nephologists believe that an increase in global temperature could decrease the thickness and brightness (ability to reflect light energy), which would further increase global temperature. Recently research has been going on at CERN's CLOUD facility to study the effects of the solar cycle and cosmic rays on cloud formation.
