1. Just to point out the comparison being made, Erie is the smallest in Volume of the Great Laeks

For more on Lake Erie see:

http://en.wikipedia.org/wiki/Lake_Erie

Unlike Superior the average time it takes for Erie to empty and refile is 2.7 years (Every 2.7 years the water in Lake Erie has flown out of Lake Erie to be replaced by other water from Lake Huron).

Lake Superior takes 191 years to do the same, i.e. 191 years for the same amount of water in Lake Superior to flow out of the lake to be replaced by new water that flows into the lake.

I do NOT want to minimize how much ice is disappearing, just trying to make sure everyone knows how much water is being lost.

Lake Ontario, the Second smallest lake, takes six years to empty and refill.

lake Huron 22 years

Lake Michigan 99 years:

Thus, while it would take 8 Lake Eries, that is about 3 and a 1/2 Lake Ontarios, 1/2 of Lake Huron, about 1/5 Lake Michigan, and about 1/10 Lake Superior.

To compare any lost of Ice to any of the Great Lakes shows how great a loss it is, but lets also keep the loss in its proper perspective.
