Ice Age Simplified

And it came to pass in the six hundredth and first year, in the first month, the first day of the month, the waters were dried up from off the earth: and Noah removed the covering of the ark, and looked, and, behold, the face of the ground was dry.
Genesis 8:13
There is strong geological evidence for only the most recent of the supposed Ice Ages, which these scientists call the Last Glacial. They call the coldest part of this period the Last Glacial Maximum.
---The best scientific explanation is that the Genesis Flood caused this one and only Ice Age.
*During the Flood, new seafloor formed very rapidly.

*Extruded magma heated the world’s oceans, greatly increasing evaporation from the sea surface.
*This resulted in more precipitation, including large amounts of snowfall at high latitudes and on mountaintops.
*Residual volcanism continued for centuries after the Flood, and the aerosols from the explosive eruptions reflected sunlight back into space, resulting in cooler summer temperatures.
*The cooler summers prevented snow and ice from melting, allowing them to accumulate and form thick ice sheets.
*As the oceans cooled and volcanic activity decreased, the Ice Age slowly came to an end."

Post-Flood Ice Cores

And the waters prevailed upon the earth an hundred and fifty days. Genesis 7:24

"Interestingly, in the upper halves of the Greenland ice cores, creationist and uniformitarian age assignments agree to within a factor of two or three of one another. Only in the bottom halves of the Greenland cores do uniformitarian and creationist age estimates dramatically diverge. Yet, the counting process is most difficult and uncertain in the bottom core sections, where ‘jumps’ in dust content are assumed to represent seasonal cycles. However, several factors together can plausibly account for overcounting in the bottoms of the Greenland cores.

First, seventyfold variations in dust content in the core bottoms

complicate the counting process.
Second, individual storms (thousands of which would be expected in
a post-Flood Ice Age lasting hundreds of years) can change ice dust content.
Third, uniformitarian expectations of very thin annual layers in the bottom core sections contribute to overcounting.
Moreover, creationists have pointed out that the frequencies and thicknesses of tephra layers within the deep Antarctic ice cores are more consistent with young-Earth expectations as is the lack of erosion of the Gamburtsev Mountains beneath the East Antarctic ice sheet.
For the above reasons, I think creationists have refuted claims that ice cores demand an old Earth."

Palm Trees of Antarctic coast

"Evidence for tropical trees has been found 5 km deep off the coast of Antarctica.

The BBC News reported that explorers dropped a drill rig 4 km down into the ocean off the east coast of Antarctica, then drilled another kilometer through sediment. The drill core included pollen grains of palm, and trees resembling baobab and macadamia. 

Remnants of single-celled archaea were also found.

“The lowland coastal region sported palm trees, while slightly inland, hills were populated with beech trees and conifers,” the article said.
The researchers infer from the flora that global temperatures were some 5°C warmer than today. “The early Eocene was a period of atmospheric CO2 concentrations higher than the current 390 parts per million (ppm)—reaching at least 600 ppm and possibly far higher,” the article said.
......evolutionists have no theory for why the earth should have warmed up at that time. 

Many Biblical creationists, though, without the millions-of-years timeline, believe that the pre-Flood world sported a moderate climate without a large difference between the poles and equator, just like the data indicate. 

The Flood, however, changed all that, burying the antediluvian world beneath miles of sediment – and ushering in a much more recent Ice Age whose effects are still damping out. 

Q: Which account is a better match to the data?"

And God saw every thing that he had made,
and, behold, it was very good.
