You can all label me as certifiable now if you want…
This is about ice ages. Some portions about the ice age theory – as presented – have holes in them. So, I am arguing those points and you see if my points are valid in your own minds. . .
Two years ago, over at WattsUpWithThat.com, my friend Canadian climatologist Rodney Chilton posted an article on the Younger Dryas and the Thermohaline Conveyor shutdown that is supposed to have happened. I was one of the people who vetted and edited Rodney’s paper, so it is something I had a little hand in. Rodney duly gave me credit in the Acknowledgements, even. I was quite pleased to see how many commenters at WUWT had positive comments.
Especially this one:
thank you very much for posting. i have a scientifically minded teen and have used this article to demonstrate “the way science is done”.
I am not going to comment directly on either of the topics, but will instead disuss a comment by a guy named commieBob, which was replied to by a handful of people, with a couple of them actually not having any idea what they were talking about or what science’s take was on the point of commieBob’s comment.
Ice age – What ice age?
Here’s a link to a really skeptical article:http://www.blavatsky.net/science/atlantis/emails/ice_age.htm There is ‘evidence’ that the ice ages, as we understand them, did not happen.
The first thing that attracted my attention when I found the above link was the name Blavatsky. “Verrry interesting” The new age movement might be termed “Blavatsky for dummies”. In other words, although I do not personally have the knowledge and skill to refute the information and conclusions in the above linked article, I’m darn sure it’s garbage. It is, isn’t it? Help …
I did myself read the linked article, which had some valid points and some mish-mash in it. I will pass on the mish-mash and address what I think are valid points.
To this, one comment was the following. I will comment here on the bolded parts of davidmhoffer’s comment:
I’m darn sure it’s garbage.
It is worse than garbage. The article rests upon this argument:
[Quoted improperly from the article:]
“A first and perhaps prime fact you need to know is that ice does not go uphill. Water doesn’t and ice doesn’t and glaciers don’t. Even over level ground ice doesn’t go very far. Specifically it goes up to 7 miles on level ground. Ice just can’t push ice further than that. If pressure is applied to push more than 7 miles worth of ice then it gets crushed or melts instead.
A look at the map shows that the ice would have to be pushed much farther than 7 miles.
With just this info you can see, the ice-age didn’t happen!”
An “ice age” happens when the total amount of snow that falls in winter exceeds the amount that melts in summer.
If that happens over a large area, you get a large ice sheet, it doesn’t have to “travel” to get anywhere. As for the 7 mile limitation, it all depends on speed. If the ice only moves a small amount year over year, then no crushing or melting occurrs [sic]. FAIL on the first two points of the article, no further reading required to conclude that it is drivel.
So what am I going to write about this?….
Hoffer cheated a bit on his quote of the article, by leaving out the middle paragraph of what he pasted in. Continue reading
