I recently heard a secondhand report re the greenhouse/ice age theories... this is hearsay so verify as needed- but apparently the most recent studies of prehistoric strata seems to indicate the earth undergoes regular cycles, where there is a sharp rise in temperatures for just a few years (5-20 years as I recall) and followed by a precipitious drop resulting in ice ages and glacier advance almost overnight(going from pine forests to frozen tundra in less than 20 years)... which makes sense- the heat rises, more evaporation, more cloud cover reflects the sun... resulting in a drop of temperature... and an ice age from which the earth slowly recovers.. The last bit of hearsay science is we are apparently overdue for an ice age... so perhaps the greenhouse effect of our air pollution is preventing or delaying the onset of an ice age... remember, Greenland was green when the Vikings settled there. So Florida may very well be flooded... and then freeze... and then finally re emerge as the icecaps are restored. I'm not sure HOW important this is, as I suspect that reanimation will be available a LOT sooner than we expect... maybe within 50 years. Its always impossible until someone does it, then everyone accepts it as commonplace. The most unusual thing is when people feel a sense of wonder about something.
