Re. CO2 & Temperatures
Actually, no. If the ice core data is to be believed, there's a *very* strong correlation between CO2 and temperature. BBC online have a nice intro to this at <http://news.bbc.co.uk/1/hi/in_depth/sci_tech/2009/copenhagen/8393855.stm>. Go to the link for the 800,000-year EPICA ice core data, download it, draw the graph. For anyone not familiar with Excel/whatever, who can't draw the graph, reply here and I'll upload my graph somewhere.
You'll notice that there's only one point where the correlation fails: right *now*, where the CO2 goes off the scale, and the temperature hasn't followed. *This* is what the climate change debate is all about: will the temperature follow, or won't it? Anyone who's seen this graph is going to have a hard time believing that it won't.
@El Reg: there's a fat chance that you'll even read this, let alone do something about it. But, if you do, and if you actually have any interest in climate change, then here's a suggestion for you. With every one of your climate stories, post a link to this data, with a graph added, and ask everyone to look at the graph *before* commenting on your story.
Paris, 'cos I found a picture of her scratching her crotch this morning, and that's about as relevant to IT as climate change is.
