One must note that the ice sheet has **ONLY** existed for 10,000 years.
It's very important to stress this point, as those who do not understand geologic time are at risk of thinking that 10,000 years is a long time.
It's a nanosecond on the geologic clock.
This is a very young icesheet. It's loss is noteworthy, but does not have significance when viewed on macro timeframes.
