odd plant behaviour: climate change...

Yes Dai you've got one thing right carbon emissions certainly started to rise dramatically starting with the industrial revolution and ice core analysis proves this without a shadow of a doubt. Now where the CO2 goes MAY be open to debate but there is compelling evidence that the ability of of terrestrial mechanisms to absorb it is being reduced faster than the production of CO2, hence it goes up rather than down and is providing an ever thickening blanket to keep us warm.

As far as the hole in the ozone layer goes, you really need to read the research and I'd suggest your first stop is the the British Antarctic Survey (you'll find them on the www) since they first detected it. It was a very serious problem but since the reduction in use of CFCs the 'hole', as far as I'm presently aware has largely repaired itself, certainly in the southern hemsephere. Those working in Antarctica a few years ago certainly didn't take the hole as a 'a load of bovine manure'. To them it was a real safety issue and they didn't venture out of doors during their summer months without maximum sun-block.

I've seen the radar scans of the the upper atmosphere in antarctica and there was a real 'hole'.

 

Dai - no one really knows.

But the reason I showed the graph of carbon dioxide levels is that there seems to be clear evidence of something happening that is not part of a normal fluctuation. Like Dave, I think the CO2 levels are real and potentially pose a considerable threat.

Whilst the coal guzzling Victorians didn't do much good, their impact would have been fairly small. The problem is that there are an awful lot more people today worldwide using fuel much more intensively. We now have cars and aeroplanes, and central heating and air conditioning that never existed in those days. Whilst we use a lot of fuel in the winter, the Americans use heating in the winter but then use even more enrgy in the summer running air conditioning units.

 

I don't suppose Atom bombs did much good for the atmosphere either ,but there is no doubt some are making money out of "global waming".Buying and selling carbon issues.and also filling our country with Wind turbo monstrosities.
