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."

    Unless we get nuclear winter, and plants cannot grow anymore- no more food. Or radiation levels become so high that people die before reaching adulthood or cannot reproduce.

    The conventional bombs we have to detonate to kill a couple of people are peanuts compared to MIRV missiles with 10 warheads each having 0.5 MT yield. And we have thousands of these.

    I dunno, I don't think a "few" bombs going off would be as devastating as you think. Hell, if a "few" bombs could irradiate the ocean, the ocean would already be dead because that's where most nuclear testing took place.

    As for actual damage, even the Tzar Bomba only did damage up to 620 miles away. That's a lot of destructive power, but it'd still take more than a few of them to really fuck things up. After a few hundred miles from the drop zone it was mostly just breaking windows.

    I think the biggest threat of nuclear war isn't a few bombs, but the "mutually assured destruction" scenarios where everybody just says "fuck it" and just launches all of their nukes at everybody else. In that case you're looking at thousands of nukes aimed specifically at cities.

    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.

    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.

    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.

    He never predicted "global cooling", even so his predictions were still wrong. In the autumn of 1990, Sagan made his most serious scientific blunder. Short version: Sagan assumed that the soot from the fires could reach stratosphere, which then would endanger food production in Asia. He was wrong about that - however, the ecology of Kuwait was damaged, temperatures going down more than 4 degrees C.

    Also, Sagan was only one of 5 people who wrote the paper on Nuclear Winter. A simple oil well fire (no matter how big) simply can't reach the stratosphere, an atomic explosion does - and thousands do to.

  21. The Spaghetti Monster and the Maya, UPC codes... by Fmuctohekerr · · Score: 5, Interesting

    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.
