I heard that this is one possible outcome scientists theorise about. A sort of positive feedback mechanism where more CO2 upsets the balance and produces even more greenhouse gases and a sort of runaway occurs.
However I heard that, at least once in the past CO2 levels were (I think) 30% or more and the Earth biological systems brought them down again so maybe the scenario is alarmist.

The global warming is a serious problem, but the scenario you mentioned is not a solid scientific one, in my believe.
I would refer you to WWF living planet report issued recently on Tue. 24 Oct 2006. In this report three different scenarios have been described :
1. Business as usual scenario
2. Slow shift scenario
3. Rapid reduction scenario
The report also provide catalyzing model to the transition to sustainability.
Yes, these scenarios about ending global overshoot and footprint and bio-capacity factors that determine overshoot. But still the scenarios are apply to the global warming.

most scientists agree that we have approximately 10 years to dramatically decrease our grennhouse gas emissions, or else it will be too late. If we fail to act, civilization will completely collapse by 2050.
