Our just-right planet transforming
The “circumstellar habitable zone” is the band where temperatures on planets orbiting their sun range between 212oF and 32oF. It’s not too hot and not too cold for water to exist. Called “the Goldilocks zone,” it’s just right to support life. Here on earth’s surface, temperatures have been in another Goldilocks zone for humans, but all good things come to an end.
Assimilating the research is just the beginning. We must also understand the exponential function and get a little help with paleoclimatology and synthesizing the broad range of data.
