Re: Is there enough ice at the Earths Poles to cover all land if it was to melt

I didn't know the answer to this one, but fortunately NASA has a good 

description with information about their Earth Observing System.  This 
includes a PDF on 

Sea ice with lots of information about polar ice.  According to them:

"Together, Greenland and Antarctica contain about 75% of the world's fresh 
water, enough to raise sea level by over 75 meters [250 feet], if all the 
ice were returned to the oceans."

Of course that's not enough to cover all the land on Earth, although it 
would cover about 1/3 of the total land area.  There are a bunch of other 
complications in setting an exact number, but this gives you a good idea of 
the size of the effect melting all this ice and snow would have.
