This was an ice age period. The Mystery of Wooly Mammoths. If these evidences are found, direct information on conditions following the Flood would be available to us. The more sandy the soil the more the winds can raise in a shorter time after the rains. What I saw corresponds to the idea that a post flood ice age would have less dust due to winds because everything was wet.
It is the same sort of conditioning which makes many people instinctively think in terms of millions of years for coral reef growth, for stalactites to form, and so on. It took the two of them many years, much money and several failed expeditions before the first real clue came. Volcanic history is known accurately to only years!
More dust at a time of increasing cold and the rapid onset of a much worse ice age. More importantly, we did not consider the average precipitation rate and actual depths of ice for different locations on the Greenland ice sheet. First of all, thank you for the link to it.
Greenhouse Gases The snow near the surface of the ice sheet is like a sponge with channels of air between the snow grains. The writer here is postulating more deserts by presuming a worldwide cold and dry climate. If the snow was to melt at any time during the year, some measurements such as those involving trapped gases would be spoiled.
- If it is challenged do you know on what basis.
- Nitrous oxide and other greenhouse gases also show similar trends from analysis of the ice-core bubbles.
- Then glacial flow models are tuned to this scale, assuming equilibrium of the ice sheets.
- The peak is due to the eruption in of Tambora, a volcano in Indonesia.
Furthermore, he only partially understands the climatic differences between the uniformitarian model and the creationist Ice Age model. This shows the importance of where we start. We are in an inter-glacial now. In Antarctica, by the time the ice has been buried deeply enough to no longer be influenced by the atmosphere, annual variations have been greatly dampened by diffusion Epstein, friends 3 et al. That's right - the driest!
Mr Brombley's insight quoted at the end of the article is an excellent example of pro-actively countering the evolutionist die-hard's warped hatred of God! The Bible claims to be a reliable historical record and this history from the very beginning was attested to by Christ and the Apostles. There are complications and Tom Moore is probably better at describing these to you than I am, but basically you are looking at seasonal variations. Since the ice sheet is formed by the accumulation of snow year after year, by drilling from the surface down through the ice sheet, we drill our way back in time.
What is being seen here is two possible ice ages, the first one being somewhat less and perhaps shorter than the second. However this does not necessarily have to be the case. If I presuppose a recent creation, I can look at the same data and everything fits quite nicely for me, my friend dating ugly too.
It seems to me that this would produce the same things we see in the ice cores that are now attributed to a long series of unchanging seasons. Thus, to obtain an ice core from which accurate, detailed dating can be derived, we need to find an Antarctic site where the snow accumulation is relatively high. Before I begin, I want to mention that the dating and the article are done with the presupposition of both long ages and not only uniformitarianism but gradualism. God asks us for faith in concordance with our reason, ashley dating web but not dependent upon it.
In fact, there are good reasons to believe that the ice cores are revealing important information about conditions following the Flood of Genesis and the recent formation of thick ice sheets. In order to date the ice cores accurately, the annual layers need to be thick enough to obtain about ten measurement samples from each year. Secular scientists use ice core samples to calibrate sea floor sediment dating claiming long ages.
They were taking ice cores. However, life is never as simple as implied above. Yes, the number of layers indicates many tens of thousands of years.
It amazes me that you feel freely qualified to propose answers to questions where you aren't. The Creation Answers Book. Response to Helen from Joe Meert It amazes me that you feel freely qualified to propose answers to questions where you aren't. An alternative model of recent glacier formation following the Flood described in Genesis will be suggested.
Glaciers are swallowing planes up there as well, just not as fast or as deep, smaller ice fields. There is no evidence that the ice layers going down for several thousand years were formed for any other reasons than those we know to be in effect today. There is nothing that distinguishes the layers below that from the ones above. This would easily result from volcanism and the changes in relative air temperatures, and even changes in relative areas of sea temperatures, post around the world.
Dating methods are not independent
- Thus, to examine the sulphate derived from volcanoes, the sea-salt sulphate needs first to be accounted for.
- The thickness of the annual layers depends on how much snow falls each year.
- Therefore the pattern is upset from the outset.
Colder periods are normally times of less precipitation, as cold air is dry. There are quite a few unknowns and variables associated with atmospheric acidity generation, transport, deposition and locking in the ice. As more and more snow is accumulated on top, the underlying snow is compressed into ice and the air forms bubbles in the ice.
You might also mention how moutain formation due to rapid plate movement factors into this as well. Yet they still recovered when thawed out! Yes, I will try to find out more as we go and different things are brought up, if they are, but for now, at first, why wouldn't this be an acceptable model to work with theoretically?
The lost squadron
The Greenland ice sheet averages almost feet thick. High concentrations of dust occur at the same times as the colder periods shown on the temperature graph. Thus, measurements of hydrogen peroxide dissolved in the ice also provide a good annual cycle indicator. Living near the flood prone Calif.
A question of starting assumptions
Dejected, the pair returned home. All of these factors would increase the amount of dust lifted into the atmosphere to then be blown over Antarctica and deposited with the snow on the surface of the ice sheet. This article will show that the great ages reported for the bottom layers of ice sheets depend on assumed models of past climate and are not the result of direct counting of layers.
You see, if one does not presume long ages, many rapid storms in a time of fluctuating temperatures and world upheaval can account for what we see in that graph. The purpose of my response was to present the idea that data can be interpreted different ways by different people. Thank you for finding this one, Dire Puppy.
Rocks Ice Cores and Bill Nye
At any rate, the story invented to make the mythology of the Bible seem reasonable requires that you claim different causes. Response to Helen from Joe Meert The isotopic composition of both oxygen and hydrogen deposited at the polar regions is primarily a function of temperature. Do they cause a problem for the recent-creation model of earth history? Thus, it is a logical starting position from which to create our worldview.
Yes, those not in Christ hate God and that which He revealed to us. On the other hand, there are previously unknown volcanic eruptions have been discovered from the evidence from the ice cores. Seely superficially analyzes the main methods of counting annual layers.

So I am asking for time now from you. Return to text Snelling, A. Ice cores therefore can be analysed not just for the chemical and physical properties of the ice, but also for the properties of the air trapped in the ice.
