Does this mean we are not doomed?
No, we're still doomed. Global warming, meteors, comets. Something will get us.
This probably means that there's too much ozone, and that it will be necessary to make many government grants to find a way to eliminate some of the excess O3.
Hint to future grantees: don't depend on CFC's to do the job.
Nah. We're still going to die.
Just watch what happens when the earth's axis tilts, and the ozone hole moves to the North Pole. I just hope it travels over the Middle East when it makes its move.
