What is the ideal average global temperature for the earth?

We hear everyday about global warming and climate change. We know that an increase of a couple of degrees to the average global temperature will be devastating. But what exactly is the ideal average temperature to sustain life as we know it?|||Earth maintains an average temperature of 15 degrees Celsius an ideal temperature for life to thrive.|||Hm, there is an entire discussion about that. Depends on what species live at the moment. In the past temperature was greater, but species who lived at that time were adapted. In the present, it's colder that most of eras in the history of Earth. But there is a difference. Most of the time there was some super-continents or even just one super-continent. Today continental mass is split and a raise of temperature will trigger more extreme environments and extreme weather (water feeds hurricanes).





You'll figure more if you take a look on paleontology to see how life behaves in different conditions and how was the climate during the geologic epochs.
