I'm not sure you can blame Maggie for this -
Some interesting charts on that link and links from it Gill.
The rise and fall in temperature does seem to have been remarkably regular over the last few millions of years.
It looks like we are just following a well established pattern.
Maggie funded the research into finding the now doubtful correlation between temperature and CO2, to her own ends.
If she hadnt instigated this then presumably there wouldnt have been such a rush to declare that man was to blame for global warming and we would just have been worried about how to run the world when fossil fuels ran out.
I think the blame lies firmly with her and her advisors of the time.
an increase of just 0.04% would cause the atmosphere to hold a lot more energy-
I would be interested to see what effects on global warming occurred after such massive volcanic eruptions from the likes of Krakatoa and Vesuvius.
The one on Hawaii is quite big as well and presumably they all have individualy produced more CO2 and other greenhouse gasses with each eruption than mankind has done for a century or so either side of their eruptions.
I dont think that the earth is as delicate as you think Sam, plus any increase in CO2 is absorbed by the oceans and any defecit is released by the oceans.
Nature works quite well at maintaining the status quo, although it can take a thousand years or so to compensate for these natural variations.
