The American Geophysical Union recently published Aerosol and cloud effects on solar brightening and the recent rapid warming. The paper uses evidence to theorize that the recent drive to clean our skies of pollution aerosols has increased the amount of sunlight that reaches the Earth and has aided the greenhouse effect in warming the Earth.
This, if true, is a prime case of good intentions pave the road to Hell. No one can deny that the Earth is a massively complex system and ideas that tinker with processes like climate cycles need to be fully weighed before initiated. Clean skies seems like a simple, noncontroversial idea. However, it serves as a warning from jumping to conclusions.
