This Is the Way the World Ends
Dave Knott writes "The CBC's weekly science radio show Quirks and Quarks this week features a countdown of the top ten planetary doomsday scenarios. Nine science professors and one science fiction author are asked to give (mostly) realistic hypotheses of the ways in which the planet Earth and its inhabitants can be destroyed. These possibilities for mankind's extinction include super-volcanoes, massive gamma ray bursts, and everybody's favorite, the killer asteroid. Perhaps the most terrifying prediction is the reversal of the Earth's magnetic field (combined with untimely solar activity), a periodic event which is currently 1/4 million years overdue."
not a single one of them even considered the possibility of streams getting crossed...for shame!

Wait till I find my r-37, space modulator.
I think I just cashed out all my cool points.
We still have those bombs, remember?
What about that? I think it's still much more likely than the other options listed. It wouldn't end the Earth (nor would for example Gamma burst), but it would end the civilization and/or kill all humans.

I always love it when people say these things. Point of fact, we don't have enough data points to make this prediction. At best, that's a wild conjecture.

I sincerely hope that we'll be able to set up colonies on other planets or in other solar systems before something snuffs out life on Earth. Our survival as a species will depend on it.

According to the International Earth-Destruction Advisory Board, the current "Earth-Destruction Alert Level" is "RED". Which means that the Earth has been destroyed.
A quote from the FAQ:

Anyway, for you deluded fools who think the Earth is still around, take head of this warning:
Obviously it's a little out of date now, 'cause those rascals at CERN managed the job, but still...
I note that the fools from the article don't actually want to destroy the Earth (well maybe one or two of the scenarios might break it apart or something), otherwise they would have come up with some scenarios like:
(Quote and methods from How to destroy the Earth.)
Fools, I'll show them all!

Even the most retarded religious fundamentalist understands that dropping a nuclear bomb on someone who has one, or has a country which has one for a friend, isn't such a bright idea.
No, more likely, the world (or more precisely Humanity, the planet would do better without than with us on it) will slip back to feudalism as cheap energy resources wane, and a sizable portion of the earth population will be destroyed by an ugly, multi-decade, low-level world war fueled by bigotry and poverty.
"Overdue" has no anthropomorphic undertone. If the Haley comet shows up one year late next time around, it'll be one year overdue.
As for the Earth's magnetic field reversal, they have occured regularly and very often in the past, so the next one is overdue, period. Same as the Big One in California. It has nothing to do with people promising anything, it's just a matter of probabilities.
Think of it as being past the 50th percentile on the probability distribution, not past the 100th percentile.
Perhaps the most terrifying prediction is the reversal of the Earth's magnetic field (combined with untimely solar activity), a periodic event which is currently 1/4 million years overdue.
From the record of paleomagnetism found in spreading ocean floors, the reversals are anything but periodic. Reversals recur, but the interval between reversals can be less than 25 thousand years, or longer than 35 million years. In other words, the intervals between reversals vary in duration by a factor of more than 1000.
The oceanic record is limited to the last 200 million years, at most. It has been extended further back by correlating measurements from continental rocks formed at different times, and relying on models for tectonic drift. This naturally yields inferences with lower confidence and limited time resolution. However, the results suggest that geomagnetic field has occasionally been stable for more than 50 million years at a time.
http://en.wikipedia.org/wiki/Magnetic_reversal
Given that their occurrence is erratic rather than periodic, and that there is no decent model for predicting their occurrence, the assertion that a magnetic reversal is "overdue" is absurd.
The scaremongering that a reversal would lead to "the end of the world" or mass extinctions is equally puerile. Reversals of the geomagnetic field show no particular correlation with extinctions in the past.

Some of the fundamentalists BELIEVE in their god. They don't care if they all die, so long as they go to heaven.
People shouldn't still be anthropomorphizing natural phenomena.
Yeah, the universe hates that.
Do you happen to know which data points we have?
Anyway I think it will just be another year 2000 fiasco, lots of worries and then nothing happens.
Sure it may fuck up all satellites and some communication but so what? It's not the end of the world.
Actually we have data points going back millions of years. They show flips of the magnetic field happening more frequently, and the current state we are in (with north at the north pole) has been this way longer than most of the other flips lasted.
And no, it won't end the world at all. The world has been through millions of these flips and lasted just fine.
It's ironic how a lot of people confuse 'the end of the world' and 'the end of us'
But as a further point, it's not believed a pole reversal would just kill all humans.
When a flip happens, there are many poles, IE there could be 8 or 10 of each a north and south pole.
Each pole should roughly have a magnetic strength that totals our current one, thus each 'pole' is weaker.
Only people living under these roaming spots need worry, and even then its only expected to give another 10000 cases of cancer a year (give or take an order of magnitude, going from poor memory here)
Defiantly sucks, but not the end of anything.
Sadly, the same is true for a lot of things on the articles list. Only life is screwed (maybe), but the planet will be fine.
Overpopulation will kill us all before anything else...resources like oil and metals will be exhausted in the coming decades! the dramatic changes in the climate caused by human activity, the cutting down of rain forests will cause the populations of third world countries to migrate en mass to Europe and North America, further increasing the fights for the remaining resources...
Also don't forget that 99% of the life on earth has a lower life expectancy and thus faster propagation cycle than us. When an animal dies of cancer after 4 years that has a life expectancy of 6 and is fertile with two, life can go on.
When humans die at age 6 on average, we die out.
We used to have a Bill of Rights. Now, with the rights gone, all we have left is the bill.
No, "we" don't have thousands of ten warhead MIRV missiles (that would require a massive booster). Most MIRV missiles are in the range of two to four warheads, and the US only intends to have just over 2000 operational warheads in the near future (with a handful of two warhead MIRV missiles).
Also from the most recent material I have read the threat of a "nuclear winter" was a gross beat up. We have had multiple volcanic events that discharged more particles into the atmosphere than would happen with optimal usage of warheads to cause a "nuclear winter", and in a normal scenario they wouldn't be used optimally for that scenario.
Additionally long time large increases in radioactivity can not happen. Most fall out from a nuclear attack is gone in weeks, what is left is not enough to destroy life. Something like Chernobyl is far more dangerous to the bio-sphere, and the Chernobyl area is still teeming with life.
Global thermonuclear war is not an extinction level event with even the levels of armament at the peak of the Cold War.

That's just neocon propaganda. In reality the governments of Iran and North Korea are made up of rational people who will always act in their countries' long term best interests despite their rhetoric. They are totally unlike the US government which will screw up and start wars because of the sort term interest of the ruling class and/or a miscalculation and plunge the world into chaos.

Right. And you know this how? The Saudis are rich enough to have bought all the nukes they wanted (from Pakistan, North Korea, say). And they're as devout as they come. But they haven't sent us all to paradise/hell.
Funny thing, fundamentalist leaders don't sacrifice themselves. And that goes for Muslims as well as Christians and Communists.
The whole nuclear winter thing is a bunch of politics getting mixed up in science. Thus far, there has been no good proof that there's any sort of reality in it. For a decent paper on it have a look at http://www.uow.edu.au/arts/sts/bmartin/pubs/88spp.html he covers some of the background of the politicization of the concept.
As for Sagan himself on the issue, his research seems more speculative rather than concrete. Remember he also predicted that the first Iraq war would lead to global cooling because of the particulate matter generated from the oil fires Saddam threatened to set. Well indeed Saddam did set those fires as he threatened and it had no measurable impact on our climate.
Don't confuse scientists speculating on things with real empiricism. There's lots of interesting ideas and theories, something with mathematical or computer models to back them up. That doesn't mean any of it has a thing to do with reality. That proof is separate.
String theory would be a good example. It is, in fact, not a theory. It makes no testable prediction. It's a neat bit of math and who knows, might even be correct. However at this time all it is is a neat bit of math, a hypothesis on how things might work. It won't even be a theory until they figure out how to make some testable predictions and won't be at all something to hang your hat on until there've been some serious tests of those predictions.
I once read an anecdote, I don't know if this is true, that in the 1700s the British set couples of goats loose in desert islands. The rationale was that castaways who eventually arrived at those islands would have a source of meat and milk. However, when someone visited those islands years later, there wasn't any life at all in the islands, only goat skeletons everywhere. The goats reproduced as long as there was food, and after they had eaten every plant they all died.
One can imagine a similar scenario for humanity. Not that we would eat every plant on earth, but if civilization were destroyed by overpopulation, maybe some plague would kill the survivors. Look at AIDS in Africa to see how lethal is a disease that's left to evolve without control.
Everybody being wiped out is a low-probability scenario, I agree, but not completely impossible.
The world population is increasing exponentially. Nothing increases exponentially in a limited environment, so the most likely scenario is that we will simply continue growing our consumption until we run out of the resources which allow the growth. oil, water, energy etc. Then the carrying capacity of the earth will be drastically reduced and with that goes the number of living things. In the final stages of growth humans will displace most other lifeforms which compete for resources.
You could use yeast in a bottle as an example. It grows until all the sugar is consumed, or alcohol level is too high, then it all just dies off.
Our bottle is simply larger.

That's totally unrealistic. No self-respecting Geek would use a GUI to control nuclear weapons. He'd have a command line interface and some shell scripts to automate the more tedious processes.

We are the United States Government! We don't do that sort of thing.
Humans (the genus Homo) *have* experienced, and survived, several polarity reversals in the past: both short terms events as well as major reversals like the Brunhes-Matuyama reversal 0.8 Ma ago. Some of the smaller duration events (like the Mono Lakes, Laschamp and Blake events) happened while Homo sapiens was already around.
In other words, it seems past examples show we really do not have to fear the end of humanity when the earth geomagnetic filed reverses. There is no record of extinctions tied to reversal events.

And hey, if you're going to include a science fiction, why not include a couple biblical/religious predictions? I for one, welcome our 6-winged Seraphim overlords...
Now that I think about it, I'm pretty sure everything I just said is completely wrong.
For the world to truly end, as in no more planet Earth, scenario 4 is most probable in the near term and scenario 1 inescapable in the long run. If you are defining âoeend of the worldâ as in a major extinction event, with Homo sapiens in a staring roll, then there are a bunch of options. The ones suspected of causing or contributing to major extinction events in the past are outlined in chapter six of my book, The Resilient Earth (shameless plug). Here are the main ones from the book.
Our planet's past is filled with extinctions,some large, some small, some solitary. All the ages in the fossil record chronicle the departure of species from this Earth. The sweep of geologic time, comprising more than 90 recognized time periods, is partitioned by changes in the fossil record. What is most amazing is how gigantic an event has to be to be recorded in the strata.

Has anyone else heard such a thing? Or is the local evangelical pastor mixing up his Mayan and Biblical eschatologies?
Possibly. Most people, particularly bible-thumpers, have a problem with rational thinking in general. I am a Christian and I believe in "prophecy" but I know the difference between my faith and my "provable knowledge," and more importantly I know the difference between what our faith really teaches and what the "conventional wisdom" might be.
In other words, and to answer your question, there are several ways to get to 2012 in Christian eschatology. Most of this stems from the "rebirth of Israel" in 1949 and some things Christ said about His return which puts us within a decade or so of some events that will supposedly take 7 years to complete, significant milestones midway, and depending on certain calculations involving the Passover, you can get there. There is no formal connection to the Maya, but I doubt anyone who believes this would listen to you. Once you've heard a pastor talk about how many letters are in the 'Reagan,' UPC barcodes, or that Obama is going to lead a Muslim revolution, you tune out. A Christian business owner I know of once even switched from Unix to Windows because he watched a consultant type 'chmod 666.'
As soon as a Christian begins listening to their local 'inspired' pastor, watching the Discovery/History channel, reading Bible Codes, the "Left Behind" series, and throwing out logic and reason and indulging in magical thinking in general, all hope is lost for them making any sense. I don't know about your inlaws, but the 2012 stuff seems to fall into this category for me.
There IS a "star" that falls in the Revelation to John. It does "poison the waters" and it is called "wormwood." I don't really know what all that means, but it is clear that it is NOT the "end of the world" and there is absolutely NO reason to assume that it will happen in our lifetimes, or in 2012 for that matter. People who say things like that have abandoned reason, which is (according to Wesley) one of the four key paths to working out your personal theology.
Which is NOT to say that believing these (or some of these) prophecies are true is necessarily irrational. If you KNOW you don't have scientific or empirical proof, YET you still believe that God exists and that he spoke to one of us through a dream/hallucination/vision 2000 years ago, AND you find it consistent with other prophecies (Ezekiel, Isaiah) and things that Christ is supposed to have said, that is perfectly sound reasoning. You may be completely wrong in the end, but there is no logical error here. There are risks with assigning probabilities without all the facts, but hey, that's induction. And being human.
When presented with a choice and there is no proof either way (such as 'is there a God') you can either ignore the question, or make your best, inductive guess. Either position is reasonable.
Contrary to popular opinion around here, religious or philosophical beliefs are not necessarily irrational in themselves. Most of my "religious" beliefs are clearly conclusions I've come to WITHOUT conclusive evidence or proof. Knowing - and acknowledging - this is key. Most inductive reasoning (not mathematical induction) is the same, and is not necessarily illogical or without value. Logic and reason are not orthogonal to faith in a creator, or even a savior. Bible codes, Intelligent Design, "bibliolatry", and the circular reasoning rampant in religion (and of all faiths) are all very much mutually exclusive to sound reason.
Personally, I find the Judeo-Christian prophetic tradition to be very interesting, and required reading if you want to understand the faith(s). The book of Daniel is amazing to me (though technically not a prophecy) and is so amazing the writing has been dated to much later than traditionally held because, in part... it "predicts" the future... and that's impossible.
Let the reader decide.
Prophecy doesn't "predict"
