Long ago humans lived in Eden, limited in number and in harmony with our biosphere. Now we are a hyper-civilization that is only made possible by the overuse of dense energy sources such as polluting carbon fuels to manifest a colossal population of over-consuming humans that cannot last on a finite planet with a biosphere that uses self-correcting feedback loops to cycle through periods of chaos to achieve recurring states of balance. The rub is this: transitioning from a state of imbalance to a new but unknown balance that falls on a continuum from icehouse to hot house means death by chaos. The partitions of life that occur in various climatic zones (including the oceans) will transition to survival or death depending on the specific disruptions that occur as the biosphere resets to land somewhere on the climate continuum. Eden may or may not return in some distant future as a climate most favorable to humans. Our current horror is that the timeline to chaos has been drastically shortened to less than a generation by modern society's misuse of dense carbon energy that continues to rapidly heat the planet with a blanket of atmospheric CO2 gases. People have a sense of the climate horror as arguments persist about the timeline to chaos. Nothing is certain. Therefore, noting can be planned with certainty. Live until you die.
