Yeah we don't need to look to far a field for an example of runaway selection. It is one of the foundations of modern climate science"Runaway" means a positive feedback (amplification) situation from which there is no recovery. The planet has experienced ice ages and warmer periods, so obviously it has also moved away from them. Enough time has passed that if any such feedback mechanisms existed, one of them would likely have manifested and the planet would be an ice ball or a hot foggy greenhouse. There have always been negative feedbacks - mechanisms set in motion by shifts to cooler or warmer regimes, which mitigate and reverse the cooling or warming.
The planet has been an ice ball and has been a hot foggy greenhouse???
