Don Aitkin posted a comment on the melting of the Greenland ice cap here and mentioned the case of some WWII fighter planes having to make an emergency landing after running out of fuel etc due to severe weather. The planes were 3 miles from where they landed, and buried under 82 metres of ice over a period of 48 years.
Let’s make it 50 years to round things off and 3 miles becomes 5 km (also rounded off). Ice accumulation is 1.7 metres per year.
Empirically this suggests the Greenland ice cap, with a maximum thickness of some 3 km, only took 1,765 years to form, everything else being equal. The current estimate of the is 110,000 years from isotope data. And if we use the generally accepted thickness of more than 2km, then it’s about 1,176 years old.
Which age does one accept?
Why is Greenland called Greenland when it is obviously a whiteland.
