My takeaway was that Earth as a system has operated outside of these temperatures and did not result in a runaway effect. This means that there are self correcting systems that allow Earth to be relatively stable and life bearing for billions of years. My first thought is that with increase in temperature, you get an increase in plant life which reduces CO2 levels resulting in lower temperatures and less plant life.
