Yeah.

Knock ya-self out!

Bugsy,

It seems that the 'hole' was known in the 1930s, before CFCs were widely manufactured (see the comments to my original post on my website). And one of your diagrams only goes to 2003. I agree with you about concentrations, and made the point myself, though I did pick it up from someone else.

When the ozone hole was discovered, only thirty years ago. It was assumed we were responsible. (on what evidence?) CFCs were blamed, we stopped using them, and the Ozone hole has done what it has probably done for centuries if not since the dawn of time. The Earth system is far too complex for the current crop of "scientists" to understand using models into which they plug the wrong data. The old computer speak term GIGO comes to mind.

Thats a hell of a reference you provided there Don!

"Someone told me..."

LOL

"one of 'my' diagrams only goes back to 2003"... well you could look up more comprehensive data yourself you know, it was just an example.

You really are turning into an old conspiracy theorist aren't you.

And thanks for that enlightening comment poida, you are so much smarter than me.

To quote your comment on knowing about the ozone 'hole' in teh 1930s:
(from your website, Don)

"A correspondent suggests to me that 'The so-called hole in the ozone layer was a well-recognised phenomenon well before fluorocarbons were invented. It affected radio transmissions that were directed around the polar regions and there were monthly charts published to guide radio amateurs transmission (antenna) directions."

You seem to be very credulous when it comes to these things. How were they able to measure ozone in the 1930s and publish charts on it on a monthly basis?

But that is irrelevant because they weren't measuring the 'ozone hole' at all were they?

Your 'correspondent' wouldn't happen to be referring to charts that are commonly published to predict the best radio propagation directions? These are still published and are generally affected from solar activity (sunspots etc), but I haven't heard that the ozone layer massively affects it because its mainly happening in the ionosphere above the ozone layer.

But please let me know when you find something won't you?

Just a squashed Bug on the Window of Life :)
