Someone said "where I live the ice was a mile thick 20K years ago" I have to assume he meant some city in a well populated area, not some area unpopulated like an ice shelf. Are you claiming that the Laurentide ice sheet wasn't a mile thick in many places? Sorry to burst your bubble, but it was. Your criterion for populated cities is meaningless. Back then, the entire area was, except perhaps for the occasional straggler, devoid of humans. -- Get A Free Orbiter Space Flight Simulator : http://orbit.medphys.ucl.ac.uk/orbit.html |

Notice where he says "where I am", indicating he is talking about a well populated city "TODAY". I am asking does it make any sense that ice was a "mile thick" in the area 20K years ago? I am asking about the AREA he mentioned, not greenland. Please, I am not asking a difficult or trick question. |

Unless you accept that the debris dragged by the mile thick glacier from Canada all across Ohio, Indiana and Illinois shows that there was a mile thick glacier here, and there were no men here then, and the temperature was below freezing under the ice, it must be a trick question. There are no bones of man in the US from before 11,000 years ago, but there are bones of Woolly Mammoth and Sabre Tooth Tiger in Texas. I don't understand the problem, what is the trick?

Joe Fischer Joe, you may want to also remind them that during that ice age sea level was as much as 350 feet LOWER than it is today. Maybe then the doubters can do their own calculations and determine the massive quantity of ice that stored that much water. Also, we are still recovering from that ice age and hence sea level is still rising - it is a natural occurrence. |
