Bohemians live in alternative spaces, these are places that are not normally considered suitable for living in. They don't make wealth their priority. Money is only a means of survival, so they can live for their arts/craft/music/literature...etc.
What causes ice-ages? Fluctuations in the amount of insolation (incoming solar radiation) are the most likely cause of large-scale changes in Earth's climate during the Quaternary. In other words, variations in the intensity and timing of heat from the sun are the most likely cause of the glacial/interglacial cycles.
As a result CO 2 levels fell and the greenhouse effect weakened, triggering an ice age. There is some evidence that the ice came and went in regular cycles, driven by changes in Earthâs orbit. If true, this would mean that the Karoo ice age operated in much the same way as the current one. Antarctica freezes over. 14 million years ago
