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.
A Rapid Ice Age. Most creationists agree that there was one major Ice Age following the Flood. The timing of the Ice Age is quite significant, since uniformitarians claim that each ice age over the past 800,000 years lasted about 100,000 years.
