"On this chart temperature rise precedes CO2 rises."

I think you must have linked to the wrong chart Sawzaw, because the one you have linked to doesn't appear to show that happening.

In any case, so what if it the charts had demonstrated that happening? One of the effects of global warming is that CO2 levels do go up in a process of positive feedback. One of the biggest worries at present is that, as the permafrost melts, it will release enormous quantities of trapped CO2, causing yet further warming. In fact the CO2 released in this way is liable to far exceed the amounts we have released through our way of life.
