Big holes in the ozone (atmosphere) appear. That's why global warming is happening.
The thing is, the atmosphere doesn't end abruptly. Rather, it gets thinner and thinner (less dense, to be precise) as you get away from Earth. "Outer space" is often defined as starting at an altitude of 100 kilometers above sea level - or some similar value.
The thinnest atmosphere belongs to planet Mercury . . . it may have no atmosphere, at all.
The atmosphere gets thinner the higher you climb, which is why oxygen tanks are used by climbers scaling Mount Everest.
It gets thinner (the pressure drops) and colder.

When the ozone layer gets thinner, its power becomes low. It causes the UV to penetrate it.
the air gets thinner.
The Earth's atmosphere gets thinner and thinner as we go away from the earth. It becomes negligible at a point in space. Beyond that, there is no atmosphere, only vaccum.
the air gets thinner as you get nearer the top.
