Since the extreme rising oceans have been debunked, change to inches instead of feet, what really is the downside of gobal warming? Can someone please explain?

The other question that I have is how can ozone be a pollutant, when it is just charged oxygen and very unstable? I read that it was a pollutant because it was an indicator of the presence of other pollutants. Does that mean that that the other pollutants are in too small quantities to measure, so they measure the ozone?

Ozone is considered a pollutant at ground level because it doesn't naturally occur there and when it is generated it combines with nitrogen oxides to form smog, while high up in the atmosphere it is formed naturally and serves to shield some of the solar uv rays.
