My friend
Ian recently asked if I might do an Ask Allie entry on self-fulfilling prophecies, namely "Will people freaking about eventual armageddon actually manage to bring it about?"
It's an excellent question, especially in the current political climate, because short of dogs and cats living together, humanity is reaching a point of mass hysteria. Ancient historical rivalries are reaching a breaking point in Israel and Palestine. Pakistan and India are likely going to come to blows as well. And to top it all off, America went and elected the Negro-Islamo-Antichrist for President. (<---That there is a joke, see? Well, to me anyway). We are also obsessing about natural phenomena that seem unprecedented, even though they truly aren't. There is a slight bit of terror underfoot about our planet being on the brink of destruction from massive floods, supervolcanoes, asteroids, rogue planets entering our orbit, and solar radiation, and if you spend enough time on the right websites with enough people who share the same amount of paranoia, you too might come to think that the end of days is right around the corner. Well the truth is, the "end of the world" has been imminent for millions of years.* This planet has been experiencing massive change on a geological scale since its formation, and it's going to continue to change--with or without our help. Let's go ahead and discuss a few of those things right now.
1. Asteroids/Meteors: There are not enough human beings on this planet who are smart enough or equipped enough to monitor every part of the celestial skies for incoming chunks of giant space rock. For every one that we have our eye on, there are thousands of others floating out there that could slam home at any time and either end human civilization "dino-style" or wipe out a good chunk of it. This has been the case since our early ancestors were clubbing their dinners to death, and it will continue to be the case long after we are gone. Our atmosphere is thick enough to burn up or bounce back into space the little guys that try to make landfall, but we engage in planetary Russian Roulette on a daily basis without even realizing it. The question is, how much sleep are you losing over it? And how much do you plan to? I hope not much. At least until we elect Morgan Freeman for President.
2. Yellowstone National Park/Supervolcanic Eruption: Many people were not aware of this until a few years ago when the Discovery Channel
made that movie that made a lot of people shit their pants, but much of Yellowstone National Park is actually one of a few gigantic underground volcanos (or "supervolcanoes") on this planet. The caldera at Yellowstone is about 35km across (or about 22 miles). All of the geothermal and seismic activity at Yellowstone is attributable to this. And according to some vulcanologists, it's overdue for an eruption. It apparently blows its gasket every 600,000 years and it's been 640,000 years since it has popped. If Mount St. Helens were the Hiroshima bomb of volcanoes, then Yellowstone would be several thousand of them going off at once. It would be the sort of eruption that would change the planet as we know it. It would spew billions of tons of ash into the atmosphere and blanket most of North America in a foot of it within a couple of days. It would then circulate around the world, block out the sun, kill all of the animals and vegetation, and bring about another ice age. I shouldn't need to remind people of the human casualties this would cause. There would be no escape from the effects of such a catastrophe.

What is causing the current fervor over this otherwise ignored (at large) ticking timebomb is the fact that there have been about 500 tiny earthquakes below the surface of Yellowstone Lake since December 27th or so, which is unprecedented in the 20 years we've been monitoring seismic activity at the park. This is causing many people to go "zOMG! VOLCANO!" Understandably so, especially if you live in or near Wyoming.
But let's think about this for a minute. The scenario I just described to you is "worst-case." If there is an eruption at Yellowstone, it would likely not be quite as catastrophic. Yes, it would definitely have an effect on the U.S., but it would not bring about an end to human civilization as we know it. Provided, of course, we don't kill each other over the last can of creamed corn in the grocery store. Also, there is no frigging way to stick an arbitrary time table on events such as these. If Yellowstone popped 640,000 years ago and it's "overdue," then in geological time--when a millenium equals a "couple of minutes"--that means Yellowstone could erupt in another 5,000 years. We simply can't be certain about such things. Also, since we've only been monitoring seismic activity for twenty of the several million years of this volcano's existence, we really can't judge with ANY accuracy about what is "unprecedented." Swarms of earthquakes come and go. They can signify a natural movement of tectonic plates or perhaps an encoraching geyser eruption. It has also been revealed that wind can have an effect on the equipment that measures harmonic wave activity, making it looks as if there is an earthquake swarm when there may only be a mighty wind blowing through the place. In other words, people are in a panic over something they know very little about. Yellowstone is indeed a sleeping giant, and one day it may wake up. But like with those unknown asteroids that come within striking distance every single day, we waste our time belly-aching over it.
3. Magentic Field Switcheroo: The sun's magnetic field shifts with some regularity, about every decade or so. What was once our star's magnetic north is currently in the south and it's expected to flip back in 2012. This happened a few years ago, and when it does happen, it basically means a lot of sunspots--which can have a bad effect on our telecommunication satellites. But it's been evidenced for quite sometime that the earth's magnetic field is also in the midst of a change, and it happens far less regularly on a human scale, but quite regularly on a geologic one--about every few hundred thousand years. In other words, there could come a day when your compass is pointing south rather than north. It is theorized that while this change is occurring, we will have far less protection from the sun's radiation. Oceans will heat up significantly and the planet will become unbearably hot. Humans, vegetation, and wildlife may not survive such a change. The people responsible for tracking such changes can only guess. At the moment, earth's magnetic field is weakened significantly, which could mean that we're in the process of a flip as we speak, but some trends show that the field weakens from time to time before resuming normal activity.
There are far more natural catastrophes that could end our time on this planet: rogue planets, melting ice caps, the earth tilting on its axis, an alien fucking invasion. But strangely enough, I am not worried about those things. They are out of our hands. Earth is just going about its earthly business, almost as if we aren't even here, and that's just fine. Meanwhile, its supposedly advanced inhabitants are busy threatening to nuke each other over who truly is entitled to a strip of "Holy" dirt. That is something worth worrying about. As a civilization, we haven't even begun to cut our teeth and it's very likely we will not even make it out of the toddler phase before we bring about our own destruction with one of our very own toys.

It all comes down to this: Humanity is engaged in a constant struggle between those who want to move forward and become enlightened, and those who are terrified of the wrath of some drummed-up mystical being with the manners of a spoiled child (thank you Robert Heinlein). Oh sure, we have other demons as well, but religion is the earth-ending doozy. Humans drummed those mystical beings to help them explain the mysteries of the universe during a time when we couldn't look to the heavens with telescopes or measure brain activity with EKGs. We invented them the way we invent Santa Claus and the Tooth Fairy to pacify young children into submission. To provide them with simpler answers until their minds have matured to grasp the bigger truths of the world. We all eventually grow out of our fascination with St. Nick and we come to understand that it is not a fat dude in a red outfit who is responsible for spreading good cheer. It is us. It's our bag. Our responsibility. It is my hope that we will come to feel the same way about our earthly fates and stop resting our laurels on myth and fantasy, or those myths will eventually destroy us, and far sooner than a burp from beneath Yellowstone.
Oh, and then there's the bird flu...
