Thick Ice Sheets: How Old Are They Really?
by Jake Hebert, Ph.D. *
Secular scientists claim that ice in deep cores extracted from the thick Greenland and Antarctic ice sheets is hundreds of thousands of years old. Do these ice cores prove an old earth?
Although these scientists believe the ice sheets to be millions of years old, vast amounts of time are not necessarily required for their formation. “Back of the envelope” calculations show that if current average snowfall rates have always been the norm, then the Greenland ice sheet could form in about 5,000 years and the Antarctic ice sheets in a little more than 10,000 years, ignoring factors such as melting.1 Of course, melting would increase the ice sheet formation time, but higher snowfall rates would decrease the time. Therefore, the 4,500 years since the Flood provide ample time for the growth of the thick ice sheets we see today, considering the much greater snowfall during the post-Flood Ice Age.

This is NOT the thick sheet you are looking for.
There’s an assumption the ice sheets didn’t exist prior to the flood or they completely melted during it. Personally, I believe such an event would be local, not global.
It pains me to see Creationists stuck in this 6,000 year old “young earth” meme.
The Bible makes clear that time is no constraint for God and that “a day is as a thousand years and a thousand years is as a day”
Creation, YES!
Young Earth, NO!
Which came first? Counting ice layers or estimating total time period.
I assume the process the article suggests is not how the ice layers age were determined. I assume the scientists first estimated how long the Antarctic and Arctic were in zones where freezing temperatures existed. Finding the total years, they then probably allocated that total sum to the ice cores. I would then assume they would try to find patterns within the ice cores to correspond the the estimate of total time.
The answer in the article seems to be “we have no earthly idea”, because we have to make assumptions about how much snow fell and how much melting occurred.
But the article did not stop there, it simply assumes more snow fell than melting, allowing the pronouncement that it was perfectly reasonable to assume the 4500 years in keeping with the assumption of a young earth.
It’s a mistake to read the story of creation literally. It’s known that the creation story is found in Sumerian cuneiform tablets, already ancient when the Torah was finally written down. The story was passed down orally and is allegorical.
Well, I don’t have the answer to that, but I do know that it takes three licks to get to the chocolate center of a Tootsie Pop! ;)

Some guy somewhere did some math based on numbers in the Bible and estimated that the Earth is six thousand years old. Unfortunately non-Christians and an increasing number of Christians latched onto this and now mistakenly believe the Bible actually says this. It doesn’t.
What? No “ back of the envelope” calculation on the compression of snow into solid ice? No calculations on the stretching of glaciers due to gravitational flow?
So by that logic ... it is a mistake to take the Ten Commandments literally.
I was really hoping that when they started wrapping candy bars in plastic, all the morons would choke to death. Clearly I was wrong.
Noah's Flood almost has to pre-date the Vela Supernova, so it's more than 11,000 to 12,300 years ago.
Agree with your #5.
That would be the Bishop of Ussher. And he made mistakes, we now know, because Hebrew uses the same word for “father” as “ancestor”.
No. The 10 Commandments were just that, commandments.
I believe their age can be dated by the microscopic pollen that are found in the ice.
Except for that bothersome genealogy from Adam to the Messiah.
Either it is true, or it is not.
God is infinitely more creative than these ICR stooges.
