Also, what I'm worried about is this...
There is evidence to show that the way the earth moves and tilts around around the sun changes, which is one of the things that leads to "normal" climate change. Those normal changes match what we have discovered from drilling ice layer tubes going almost half a million years back.
These layers show that *after* these hot peaks of the world's climate there is an increase in c02, this lags behind so it is only after the earth starts to cool down there is a peak of c02. I think this is due to the earths eco system taking a beating and there being a lot more death than usual, life hangs onto carbon so when a lot of it dies a lot of that 'living' carbon is released. There is also a lot of stored carbon in the surface of the earth that can be released... like when peat dries out due to being, well drier than before, due to a falling water table.
Anyway, what I'm worried about is having a lot more c02 around when we enter the warmer times (warmer times due to where we are in relation to the sun) it's normally not there see? Not at these levels.. And we do know that c02 is a 'greenhouse' gas, its a pretty old and understood experiment.... Btw, it was actually Eunice Foote who identified CO2 as a greenhouse gas in 1856, a woman none the less!
The ice layers seem to point to us being at the start of that warm cycle too.
I'm sure at some point we will be able to pull liquid fuel right out of the atmosphere using sunlight, but again I want the earth to see such things happen, and not extinct ourselvess before we realise such!
