Problem
Dupont, a chemical company, recently invented a nanoparticle that can reflect visible and UV light. Dr. Danny Kim, the principal researcher for the nanoparticle, wants to use this nanoparticle for sprayable sunscreen. Unfortunately, once airborne, this nanoparticle will stay in the atmosphere for a very long time. If this sprayable sunscreen becomes widely available and used by people, how do you think this nanoparticle would impact climate change? Explain. Answer the question in terms of radiative forcing, not health effects.
