So Richard - couple questions here for you to ponder.  What do you suppose happens to all the water when these huge ice sheet melts?  If the sea level rises 2ft how many people do you suppose would have a tough time finding a place to live?  One example would be the mouth of Ganges were about 30 million people live below sea level.  How would you propose relocating those folks?  Have a look at Miami and souther Florida if you'd like something closer to home.
The idea that you who's probably never taken and passed a science class is so fervently questioning scientists across the globe is just preposterous.  The fact that you site Dennis Miller as your reference is beyond belief.
