Comment on New NAD president: ‘I love you’ doesn’t mean we won’t deal with issues by Professor Kent.

Sean,

I recognize the superiority of your geology knowledge compared to mine. I have only had one course in geology, and it was close to 40 years ago. I don’t read much, either. However, I would like to meekly offer a few suggestions that might benefit your understanding:

1. Your sources, so far as I can see, make no mention of actual erosion rates from the summit of Mt. Everest, or even specifically from Everest itself. Also, I’m not sure what you mean by the “summit,” which itself, I believe, is perenially covered with snow and would be technically very challenging to measure erosion at. So why are you making claims about erosion rates on the summit if you cannot cite a source wherein those data are produced? Range-wide erosion measured from stream sediment does not equate to homogenous erosion rates for all valleys and summits.

2. I had read about the “buzzsaw” effect of glaciers. Apparently, you did not read about the evidence that contradicts the impact of buzzsaw effect on reducing mountain height. You can start with this:

Thomson, S. N., M. T. Brandon, J. H. Tomkin, P. W. Reiners, C. Vásquez, N. J. Wilson. 2010. Glaciation as a destructive and constructive control on mountain building. Nature 467:313-317.

From their work in the Patagonia Mountains of South America, the authors wrote: “That glaciation can act to protect an active orogen from erosion opens up the intriguing possibility that, given favourable glacio-climatic, geologic and tectonic conditions, a cooling climate can act to enhance topographic relief, not in the manner originally envisaged in ref. 16 through passive isostatic response to locally enhanced erosion, but by inhibiting erosion to promote further accretionary growth in orogen height and width.” Numerical modelling and the authors’ extensive thermochronological data suggest that, under extremely cold climatic conditions–and not just in Antarctica–mountain glaciers do not slide but are frozen to the bedrock, which protects mountain peaks rather than erodes them. (Now I’m not making a claim that Everest is particularly cold; the reader can decide that for him/herself.)

3. An issue you are overlooking is that a glacier does not cover the summit of Everest. Glaciers occur downslope where avalanche falls accumulate. If I’m not mistaken, I believe the movement of a glacier is going to be less at its higher elevation, and therefore glacier-associated erosion (the “buzzsaw” effect) will be greatest at its lower-elevation margin. When you have a perennial layer of snow packed against the actual summit rock, where is all that rock disappearing to?

4. You keep speaking of the extreme slope angle, yet Everest is regarded by many mountaineers as a relatively “easy” summit because, after all, it is not as steep as many other mountains. The summit slope is relatively broad and requires comparatively little technical climbing.

5. It’s funny…you stated that erosion is, in fact, higher on the summit of Everest than at lower elevations. And then, in your later post, you wrote: “That is why the height of Mt. Everest doesn’t increase even faster – – because it is being eroded, top down, at ~3mm/year as I’ve already explained to you several times now (ala the ‘buzzsaw’ effect). Compare this rate of mountain top and side erosion to the incision rates of the river or glacial beds which can be as high as 10-15 mm/yr.” Thank you for now agreeing with me.

@ Sean Pitman

As the waters and massive tsunamis covered and reformed the planet during the Flood and subsequent aftermath, flat sedimentary layers would have been deposited which would not resemble the previous “soil” that once covered the Earth. Then, as the surface of the Earth broke up into continents and tectonic activity went into full swing, the newly formed sedimentary layers would themselves have become warped and folded – as well see today even on the tops of the highest mountain ranges in the world…

I think you’re making it quite clear that the majority of tectonic upheavel could not have occurred during the period of the flood while it was raining, as the mountains quickly would have emerged ahead of the rising flood waters. What you’re suggesting, basically, is that the extraordinary uplift of mountains had to have happened after the rain stopped.

My two questions for you:

1. Where are your data?

2. Is it ever okay to say, “we don’t have a lot of information and we don’t have a clear picture of what happened before, during, and after the flood?” Of course, we come across as more intelligent and informed when we claim to have answers. Some of us can’t resist the bait.

Funny how all those extraordinary tectonic forces during the flood failed to generate a tsunami large enough to roll the ark. Of course, angels probably calmed the water around the ark–though this (among many other miraculous Biblical events) would be difficult to demonstrate using science.

Fourth, I am bewildered as to why Seventh-day Adventists must be required to believe that reptiles and mammals (not to mention birds, which must surely be grouped with the mammals) at one time could not coexist because of different temperature tolerances. We surely don’t see this today. Mammals (and birds) abound in the hottest and most humid lowlands today, and reptiles currently abound in the cooler mountains. And, of course, to merely survive the flood, they all had to somehow coexist on one big boat called the ark.

Perhaps someone could explain to me the physiological systems of these long-extinct animals that rendered small and large birds and mammals alike (some fast, some slow) unable to live in the lowlands, and the small and large amphibians and reptiles alike (some fast, some slow) unable to live at the higher elevations (that weren’t even very high, apparently).

Fifth, I can’t help but wonder whether someone could get fired at Southern Adventist University for questioning their apparently official position. Anyone got an answer?

Nic&#032Samojluk: No wonder most creationist writers do not even try to submit their papers to such organizations.
Who wants to waste his/her time trying to enter through a door that is closed to him/her a priori?

You have no idea what you’re writing about, Nic. As it turns out, there are in fact many of us Adventists who “waste” our time publishing articles through doors that open to us a priori. Even Leonard Brand at Loma Linda, a widely recognized creationist, has published in the top geology journals. I mean the top journals in the discipline.

The myth that creationists cannot publish in mainstream science is perpetuated by people who simply do not understand the culture of science–and will remain clueless that they do not understand it even when confronted with their misunderstandings. Such is human nature.

Pauluc,

Your questions about conservation genetics are very insightful. I don’t understand how all these life forms were able to greatly increase in genetic diversity while simultaneously winding down and losing genetic information to mutations. Sean seems to insist that both processes happen simultaneously. I had the impression he has insisted all along that the former cannot overcome the latter. But I think you must be right: God had to intervene to alter the course of nature. However, we can probably test this empirically because there must be a signature of evidence available in the DNA. I’ll bet Sean can find the evidence for this.

I’m also glad the predators (just 2 of most such species) in the ark had enough clean animals (14 of each such species) to eat during the deluge and in the months and years after they emerged from the ark that they didn’t wipe out the vast majority of animal species through predation. Maybe they all consumed manna while in the ark and during the first few months or years afterward. Perhaps Sean can find in the literature a gene for a single digestive enzyme that is common to all predatory animals, from the lowest invertebrate to the highest vertebrate. Now that would be amazing.

Wait a minute–I remember once being told that SDA biologists like Art Chadwick believe that some animals survived on floating vegetation outside the ark. Now that would solve some of these very real problems! I wonder whether readers here would allow for this possibility. Multiple arks without walls, roof, and human caretakers.

Ellen White said, “In the days of Noah, men…many times larger than now exist, were buried, and thus preserved as an evidence to later generations that the antediluvians [presumably referring to humans] perished by a flood. God designed that the discovery of these things should establish faith in inspired history…”

Sean Pitman said, “All human fossils discovered so far are Tertiary or post-Flood fossils. There are no known antediluvian human fossils.”

Ellen White tells us that humans and dinosaurs (presumably referred to in the statement, “a class of very large animals which perished at the flood… mammoth animals”) lived together before the flood. Evolutionary biologists tell us that dinosaurs and humans never lived together. You’re telling us, Sean, that the fossil record supports the conclusion of evolutionists rather than that of Ellen White and the SDA Church. Many of the “very large animals which perished at the flood” are found only in fossil deposits prior to or attributed to the flood, whereas hunans occur in fossil deposits only after the flood (when their numbers were most scarce).

Should the SDA biologists, who are supposed to teach “creation science,” be fired if they teach what you have just conceded?


La Sierra Univeristy Fires Dr. Lee Greer; Signs anti-Creation Bond
For those aghast about the LSU situation and wondering what other SDA institutions have taken out bonds, hold on to your britches. You’ll be stunned when you learn (soon) how many of our other schools, and which ones in particular, have taken out these bonds. You will be amazed to learn just how many other administrators have deliberately secularized their institutions besides Randal Wisbey, presumably because they too hate the SDA Church (as David Read has put it so tactfully).

Be sure to protest equally loudly.

@Sean Pitman:

So clearly you believe that science can explain supernatural events. Congratulations on that.
