Are there holes in the ozone layer from rockets going to space and do they lead to global warming?
A hole made by a rocket is largely healed within minutes. It leaves contaminants behind that deplete ozone for some time, depending on the type of fuel it used. Water vapor (fuels that contain hydrogen) and chlorine-based oxidizers (perchlorate) lead to net reduction of ozone. The depletion of the ozone layer and global warming may share some root causes, but one has very little effect on the other.
