#723: Updated the Ozone data graph.

What I did was to add A high point for 2003 and then callout the low for 2003 so you could see what I mean.

NASA is clearly cherry-picking data. 1958 had a low of 110 DU (in September or October of 1958) but they report it as being somewhere near 300; in fact I'd wager that the 300 figure is correct for late in the year, say around the austral summer solstice, which is in December.

The right side of the graph clearly features numbers from September and October, since there is other data showing that ozone levels were clearly far above 200 DU at other times of the year.

I also noticed that my "actual low" for 1958 is, in fact, 10 units too high: I have it at 120 DU rather than 110. 120 is the actual low for 2003, though.

The ozone hole is not new. It was discovered in 1956, explained, and forgotten about, except for atmospheric scientists; it was a curiosity, nothing more. It wasn't until 1985 that it suddenly became an international ecological crisis.

I can't say that enough: it was discovered in 1956. IT WAS DISCOVERED IN 1956.

That was before CFCs were in widespread use anywhere in the world.

It is a natural phenomenon that has nothing to do with human activity.
