Columbia Engineering and Georgia Institute of Technology researchers have published a study in the Proceedings of the National Academy of Sciences showing that certain volatile organic gases can promote cloud formation in a way never considered before by atmospheric scientists. They say this is the first time gases have been shown to affect cloud formation in this way and will 鈥渋mprove our ability to model cloud formation, an important component of climate.鈥�
