Earth on the Brink of an Ice Age
The earth is now on the brink of entering another Ice Age, according to a large and compelling body of evidence from within the field of climate science. Many sources of data which provide our knowledge base of long-term climate change indicate that the warm, twelve thousand year-long Holocene period will rather soon be coming to an end, and then the earth will return to Ice Age conditions for the next 100,000 years.

They assume this because of the polarity shift.
From what I have read on this topic previously, we are long overdue for another climate shift.
Indeed we are. Theres something about like 2012 (fuck end of the world BS) but apparently the entire solar system is suppose to line up.Originally Posted by Rick Scarf
I think we should start to prepare by taking back Al Gore's Nobel Peace Prize.
Well global warming could eventually lead to a cooling of the planet. The ice caps melt releasing fresh water and this fresh water then disrupts the ocean's currents. Example, without the Gulf Stream the UK and most of north-west Europe would be almost unbearable because of the cold.
Well, I thought this was common knowledge.
The Day After Tomorrow really threw the idea into the mainstream.
The Day After Tomorrow was a crock of shit.
Actually, the expectation of the occurrence of a new ice age is not based on magnetic polarity shifts. As explained in the article, the prediction of the next ice age is primarily based on the periodicity of previous ice ages as seen in polar ice core samples, ocean sediment cores, and in other geological data. It is also based on cycles of the Earth's tilt, the shape of the Earth's orbit, and precession of the Earth's axis, known as Milankovitch cycles.
I'm not extremely knowledgeable about this, but as far as I'm aware, the link between changes in the Earth's magnetic field and ice ages isn't completely confirmed. Even if it is, the primary evidence that suggests a new ice age should be happening soon is the evidence mentioned above.
I was led to believe this myself, but it turns out that the bit about the Gulf Stream was simply incorrect.

Thank you for the link.
Interestingly, I've seen a study (let me look for a link) that points out that the correlation of the Milankovitch cycles to variations in climate show an effect that is always within upper and lower boundaries of the biochemical phase the Earth is within at any given historical period.
So it seems that while the effect of the Milankovitch cycles are certainly there, the magnitude of the effect always acts between limits set by the atmospheric and geologic context of the period being examined. This is consistent with the fact that the Earth's climate has always, at least since life emerged, been actively determined above all by it's biochemical equilibrium.
In other words, change the chemistry of the Earth's biosphere and the biochemical equilibrium will shift along with the range of temperatures experienced. The Milankovitch cycles then tend to act to affect the average temperature within that range, high when the mean orbital radius is low and low when the mean orbital radius is high.

Wait a second! What about global warming?
I hear the voices inside my head. They counsel me. They understand. They talk to me.
So how does this impact my life? How soon will this shit happen?
Long after you die.
People are actin like it could be any day now.
lol, they really are
Well according to The Day After Tomorrow it will all happen within 1 week.
People are stupid.
Hype for the media imo.
Interesting. Yeah, there has been more and more of a realization about how striking of an effect life has on climate. Obviously, the extremely chemically reactive atmosphere with a very high oxygen content can only be stable if life exits to keep pumping out O2, but other extremely large feedback loops have been discovered in which life is key, such as one associated with rain cloud formation nucleating around bacteria.
But thanks for pointing it out. I didn't realize that even with the gross global warming and cooling trend reflected in the outbreak of ice ages, life is the central determinant.

sweet ive always wanted to ride a polar bear
its not that great kind of similar to riding a black bear.
This is all bullshit. There has never been an ice age, the bible would have mentioned something of it.
(this isn't WTF news by the way)
I want an answer.Wait a second! What about global warming?
I hear the voices inside my head. They counsel me. They understand. They talk to me.
This is the problem with discussing the Earth's climate, it's not a simple it's getting hotter or colder issue.I want an answer.
Case in point. What about global warming you ask? You mean the climatic warming trend which scientists predict will occur during the next 100 years or so as a result of human activity?
Are you really asking how this relates to this article's prediction of a major cooling trend occurring over the next 100 THOUSAND years or so because of another effect completely unrelated to anthropogenic global warming?

I thought we were going to die because we killed the ozone layer and that will make us burn up and the ice caps will melt to cause global flooding.
This is what the news tells me.
I hear the voices inside my head. They counsel me. They understand. They talk to me.
i am fairly certain the ozone layer has nothing to do with global climate change
also tidus if you are trolling this thread it is just plain annoying
Half-trolling.
I am actually curious as to the direct conflict that this "Ice Age" has with global warming.
I hear the voices inside my head. They counsel me. They understand. They talk to me.
Well it doesn't
if you read MrShrike's amazingly intelligent posts itt you'll see that what he's saying is that there seems to be a short-term trend of global warming, which is part of a situation that seems to forecast a long term global ice age.
i had a different idea, which was that global warming is basically a misnomer and "climate change" is the only accurate term for what's going on, but i'm glad to be corrected.
if you're making a serious point about how this conflicts with global warming, then you're to be taken no more seriously than the guys who say "look at all this cold weather! what happened to global warming, huh?"
Well, I'm not saying that I support global warming or detest it...I was just wondering how they fit together I guess. I've always thought the Earth was going through a cycle.
I reread Mr. Shrike's posts and it looks like he sort of says that.
Way to make me feel like a dumbass.(Shush, I know I am one.)
