The past few weeks and months have reinforced my awareness that quite a lot of human habitation is precariously situated within a variety of hazard zones, predominantly but not exclusively along the coasts. The desirability of coastlines is obvious: life is especially abundant along such boundaries. Humans rely on other lifeforms for sustenance no less than any other organism, so exploiting available resources at the coasts is a no-brainer. Plus, we need fresh water, so habitation alongside lake and river systems have also been preferential sites when frontier communities were established.

Coastlines and riverbeds in particular are dynamic, changing over varying timescales as new conditions assert themselves. Some changes are quite substantial. For instance, there is evidence that a previous human civilization situated along the coasts during the last ice age (ending some 12,000 years ago) when sea level was about 400 feet lower was effectively destroyed and covered by the Biblical flood precipitated by ice sheets melting rapidly (within a few weeks, perhaps). Since then, sea level and global average atmospheric temperature have been remarkably consistent, but they’re slowly on the rise yet again. Causes may be up for debate, but there is little doubt that human civilization and industrial activity have contributed significantly.

Coasts are not being inundated all at once as before but by slow creep of rising tides onto formerly dry land. Once in a while, storm surges and tsunamis wash inland, warning of what’s to come as global warming accelerates, oceans (continue to) warm and expand, and sea level increases (by tens of meters if the most dire predictions prove correct). This is only one water-borne threat, rhyming with past human experience. Wild fires, earthquakes, volcanic eruptions, sink holes, hurricanes, tornadoes, and other natural disasters are striking all around us with increasing frequency according to this source — one reason the world is sometimes characterized as a slaughterhouse despite its amazing profundity. The three most recent disasters that amaze me (N. American bias showing here) are the California wildfires, the Hawaiian volcanic eruption on the big island, and the earthquake in Anchorage, Alaska. No need to go back in geological time; each has ample precedent in recent history. Yet we persist in living in these hazard zones and will likely rebuild and repopulate them as opportunity allows.

Whether to recommend abandonment of known hazard zones is not entirely clear to me, though I’ve ranted about the foolhardiness of rebuilding. If history is a reliable indicator and a major extinction event (process) has already commenced, it’s doubtful that anything we do or don’t do will affect outcomes to any significant extent.

I caught the presentation embedded below with Thomas L. Friedman and Yuval Noah Harari, nominally hosted by the New York Times. It’s a very interesting discussion but not a debate. For this now standard format (two or more people sitting across from each other with a moderator and an audience), I’m pleased to observe that Friedman and Harari truly engaged each others’ ideas and behaved with admirable restraint when the other was speaking. Most of these talks are rude and combative, marred by constant interruptions and gotchas. Such bad behavior might succeed in debate club but makes for a frustratingly poor presentation. My further comments follow below.

With a topic as open-ended as The Future of Humanity, arguments and support are extremely conjectural and wildly divergent depending on the speaker’s perspective. Both speakers here admit their unique perspectives are informed by their professions, which boils down to biases borne out of methodology, and to a lesser degree perhaps, personality. Fair enough. In my estimation, Harari does a much better job adopting a pose of objectivity. Friedman comes across as both salesman and a cheerleader for human potential.

Both speakers cite a trio of threats to human civilization and wellbeing going forward. For Harari, they’re nuclear war, climate change, and technological disruption. For Friedman, they’re the market (globalization), Mother Nature (climate change alongside population growth and loss of diversity), and Moore’s Law. Friedman argues that all three are accelerating beyond control but speaks of each metaphorically, such as when refers to changes in market conditions (e.g., from independent to interdependent) as “climate change.” The biggest issue from my perspective — climate change — was largely passed over in favor of more tractable problems.

Climate change has been in the public sphere as the subject of considerable debate and confusion for at least a couple decades now. I daresay it’s virtually impossible not to be aware of the horrific scenarios surrounding what is shaping up to be the end of the world as we know it (TEOTWAWKI). Yet as a global civilization, we’ve barely reacted except with rhetoric flowing in all directions and some greenwashing. Difficult to assess, but perhaps the appearance of more articles about surviving climate change (such as this one in Bloomberg Businessweek) demonstrates that more folks recognize we can no longer stem or stop climate change from rocking the world. This blog has had lots to say about the collapse of industrial civilization being part of a mass extinction event (not aimed at but triggered by and including humans), so for these two speakers to cite but then minimize the peril we face is, well, façile at the least.

Toward the end, the moderator finally spoke up and directed the conversation towards uplift (a/k/a the happy chapter), which almost immediately resulted in posturing on the optimism/pessimism continuum with Friedman staking his position on the positive side. Curiously, Harari invalidated the question and refused to be pigeonholed on the negative side. Attempts to shoehorn discussions into familiar if inapplicable narratives or false dichotomies is commonplace. I was glad to see Harari calling bullshit on it, though others (e.g., YouTube commenters) were easily led astray.

The entire discussion is dense with ideas, most of them already quite familiar to me. I agree wholeheartedly with one of Friedman’s remarks: if something can be done, it will be done. Here, he refers to technological innovation and development. Plenty of prohibitions throughout history not to make available disruptive technologies have gone unheeded. The atomic era is the handy example (among many others) as both weaponry and power plants stemming from cracking the atom come with huge existential risks and collateral psychological effects. Yet we prance forward headlong and hurriedly, hoping to exploit profitable opportunities without concern for collateral costs. Harari’s response was to recommend caution until true cause-effect relationships can be teased out. Without saying it manifestly, Harari is citing the precautionary principle. Harari also observed that some of those effects can be displaced hundreds and thousands of years.

Displacements resulting from the Agrarian Revolution, the Scientific Revolution, and the Industrial Revolution in particular (all significant historical “turnings” in human development) are converging on the early 21st century (the part we can see at least somewhat clearly so far). Neither speaker would come straight out and condemn humanity to the dustbin of history, but at least Harari noted that Mother Nature is quite keen on extinction (which elicited a nervous? uncomfortable? ironic? laugh from the audience) and wouldn’t care if humans were left behind. For his part, Friedman admits our destructive capacity but holds fast to our cleverness and adaptability winning out in the end. And although Harari notes that the future could bring highly divergent experiences for subsets of humanity, including the creation of enhanced humans from our reckless dabbling with genetic engineering, I believe cumulative and aggregate consequences of our behavior will deposit all of us into a grim future no sane person should wish to survive.

We’re trashing the planet. Everyone gets that, right? I’ve written several posts about trash, debris, and refuse littering and orbiting the planet, one of which is arguably among my greatest hits owing to the picture below of The Boneyard outside Tucson, Arizona. That particular scene no longer exists as those planes were long ago repurposed.


I’ve since learned that boneyards are a worldwide phenomenon (see this link) falling under the term urbex. Why re-redux? Two recent newbits attracted my attention. The first is an NPR article about Volkswagen buying back its diesel automobiles — several hundred thousand of them to the tune of over $7 billion. You remember: the ones that scandalously cheated emissions standards and ruined Volkswagen’s reputation. The article features a couple startling pictures of automobile boneyards, though the vehicles are still well within their usable life (many of them new, I surmise) rather than retired after a reasonable term. Here’s one pic:

The other newsbit is that the Great Pacific Garbage Patch is now as much as 16 times bigger than we thought it was — and getting bigger. Lots of news sites reported on this reassessment. This link is one. In fact, there are multiple garbage patches in the Pacific Ocean, as well as in other oceanic bodies, including the Arctic Ocean where all that sea ice used to be.

Though not specifically about trashing the planet (at least with trash), the Arctic sea ice issue looms large in my mind. Given the preponderance of land mass in the Northern Hemisphere and the Arctic’s foundational role in climate stabilization, the predicted disappearance of sea ice in the Arctic (at least in the summertime) may truly be the unrecoverable climate tipping point. I’m not a scientist and rarely recite data or studies in support of my understandings. Others handle that part of the climate change story far better than I could. However, the layperson’s explanation that makes sense to me is that, like ice floating in a glass of liquid, gradual melting and disappearance of ice keeps the surrounding liquid stable just above freezing. Once the ice is fully melted, however, the surrounding liquid warms rapidly to match ambient temperature. If the temperature of Arctic seawater rises high enough to slow or disallow reformation of winter ice, that could well be the quick, ugly end to things some of us expect.

Returning to the discomforts of my culture-critic armchair just in time of best- and worst-of lists, years in review, summaries of celebrity deaths, etc., the past year, tumultuous in many respects, was also strangely stable. Absent were major political and economic crises and calamities of which myriad harbingers and forebodings warned. Present, however, were numerous natural disasters, primary among them a series of North American hurricanes and wildfires. (They are actually part of a larger, ongoing ecocide now being accelerated by the Trump Administration’s ideology-fueled rollback of environmental protections and regulations, but that’s a different blog post.) I don’t usually make predictions, but I do live on pins and needles with expectations things could take a decidedly bad turn at any moment. For example, continuity of government — specifically, the executive branch — was not expected to last the year by many pundits, yet it did, and we’ve settled into a new normal of exceedingly low expectations with regard to the dignity and effectiveness of high office.

I’ve been conflicted in my desire for stability — often understood pejoratively as either the status quo or business as usual — precisely because those things represent extension and intensification of the very trends that spell our collective doom. Yet I’m in no hurry to initiate the suffering and megadeath that will accompany the cascade collapse of industrial civilization, which will undoubtedly hasten my own demise. I usually express this conflict as not knowing what to hope for: a quick end to things that leaves room for survival of some part of the biosphere (not including large primates) or playing things out to their bitter end with the hope that my natural life is preserved (as opposed to an unnatural end to all of us).

The final paragraph at this blog post by PZ Myers, author of Pharyngula seen at left on my blogroll, states the case for stability:

… I grew up in the shadow of The Bomb, where there was fear of a looming apocalypse everywhere. We thought that what was going to kill us was our dangerous technological brilliance — we were just too dang smart for our own good. We were wrong. It’s our ignorance that is going to destroy us, our contempt for the social sciences and humanities, our dismissal of the importance of history, sociology, and psychology in maintaining a healthy, stable society that people would want to live in. A complex society requires a framework of cooperation and interdependence to survive, and without people who care about how it works and monitor its functioning, it’s susceptible to parasites and exploiters and random wreckers. Ignorance and malice allow a Brexit to happen, or a Trump to get elected, or a Sulla to march on Rome to ‘save the Republic’.

So there’s the rub: we developed human institutions and governments ideally meant to function for the benefit and welfare of all people but which have gone haywire and/or been corrupted. It’s probably true that being too dang smart for our own good is responsible for corruptions and dangerous technological brilliance, while not being dang smart enough (meaning even smarter or more clever than we already are) causes our collective failure to achieve anything remotely approaching the utopian institutions we conceive. Hell, I’d be happy for competence these days, but even that low bar eludes us.

Instead, civilization teeters dangerously close to collapse on numerous fronts. The faux stability that characterizes 2017 will carry into early 2018, but who knows how much farther? Curiously, having just finished reading Graham Hancock’s The Magicians of the Gods (no review coming from me), he ends ends with a brief discussion of the Younger Dryas impact hypothesis and the potential for additional impacts as Earth passes periodically through a region of space, a torus in geometry, littered with debris from the breakup of a large body. It’s a different death-from-above from that feared throughout the Atomic Age but even more fearsome. If we suffer anther impact (or several), it would not be self-annihilation stemming from our dim long-term view of forces we set in motion, but that hardly absolves us of anything.

Four years, ago, the Daily Mail published an article with the scary title “HALF the world’s wild animals have disappeared in 40 years” [all caps in original just to grab your eyeballs]. This came as no surprise to anyone who’s been paying attention. I blogged on this very topic in my review of Vaclav Smil’s book Harvesting the Biosphere, which observed at the end a 50% decrease in wild mammal populations in the last hundred years. The estimated numbers vary according to which animal population and what time frame are under consideration. For instance, in 2003, CNN reported that only 10% of big ocean fish remain compared to 47 years prior. Predictions indicate that the oceans could be without any fish by midcentury. All this is old news, but it’s difficult to tell what we humans are doing about it other than worsening already horrific trends. The latest disappearing act is flying insects, whose number have decreased by 75% in the last 25 years according to this article in The Guardian. The article says, um, scientists are shocked. I don’t know why; these articles and indicators of impending ecological collapse have been appearing regularly for decades. Similar Malthusian prophesies are far older. Remember colony collapse disorder? Are they surprised it’s happening now, as opposed to the end of the 21st century, safely after nearly everyone now alive is long dead? C’mon, pay attention!

Just a couple days ago, the World Meteorological Association issued a press release indicating that greenhouse gases have surged to a new post-ice age record. Says the press release rather dryly, “The abrupt changes in the atmosphere witnessed in the past 70 years are without precedent.” You don’t say. Even more astoundingly, the popular online news site Engadget had this idiotic headline: “Scientists can’t explain a ‘worrying’ rise in methane levels” (sourcing Professor Euan Nisbet of Royal Holloway University of London). Um, what’s to explain? We’ve been burning the shit out of planetary resources, temperatures are rising, and methane formerly sequestered in frozen tundra and below polar sea floors is seeping out. As I said, old news. How far up his or her ass has any reputable scientist’s head got to be to make such an outta-touch pronouncement? My answer to my own question: suffocation. Engadget made up that dude just for the quote, right? Nope.

Not to draw too direct a connection between these two issues (wildlife disappearances and greenhouse gases — hey, I said pay attention!) because, ya know, reckless conjecture and unproven conclusions (the future hasn’t happened yet, duh, it’s the future, forever telescoping away from us), but a changing ecosystem means evolutionary niches that used to support nature’s profundity are no longer doing so reliably. Plus, we just plain ate a large percentage of the animals or drove them to extinction, fully or nearly (for now). As these articles routinely and tenderly suggest, trends are “worrying” for humans. After all, how are we gonna put seafood on our plates when all the fish have been displaced by plastic?

rant off/

Here’s a familiar inspirational phrase from The Bible: the truth shall set you free (John 8:32). Indeed, most of us take it as, um, well, gospel that knowledge and understanding are unqualified goods. However, the information age has turned out to be a mixed blessing. Any clear-eyed view of the the way the world works and its long, tawdry history carries with it an inevitable awareness of injustice, inequity, suffering, and at the extreme end, some truly horrific episodes of groups victimizing each other. Some of the earliest bits of recorded history, as distinguished from oral history, are financial — keeping count (or keeping accounts). Today differs not so much in character as in the variety of counts being kept and the sophistication of information gathering.

The Bureau of Labor Statistics, a part of the U.S. Department of Labor, is one information clearinghouse that slices and dices available data according to a variety of demographic characteristics. The fundamental truth behind such assessments, regardless of the politics involved, is that when comparisons are made between unlike groups, say, between men and women or young and old, one should expect to find differences and indeed be rather surprised if comparisons revealed none. So the question of gender equality in the workplace, or its implied inverse, gender inequality in the workplace, is a form of begging the question, meaning that if one seeks differences, one shall most certainly find them. But those differences are not prima facie evidence of injustice in the sense of the popular meme that women are disadvantaged or otherwise discriminated against in the workplace. Indeed, the raw data can be interpreted according to any number of agendas, thus the phrase “lying with statistics,” and most of us lack the sophistication to contextualize statistics properly, which is to say, free of the emotional bias that plagues modern politics, and more specifically, identity politics.

The fellow who probably ran up against this difficulty the worst is Charles Murray in the aftermath of publication of his book The Bell Curve (1994), which deals with how intelligence manifests differently across demographic groups yet functions as the primary predictor of social outcomes. Murray is particularly well qualified to interpret data and statistics dispassionately, and in true seek-and-find fashion, differences between groups did appear. It is unclear how much his resulting prescriptions for social programs are borne out of data vs. ideology, but most of us are completely at sea wading through the issues without specialized academic training to make sense of the evidence.

More recently, another fellow caught in the crosshairs on issues of difference is James Damore, who was fired from his job at Google after writing what is being called an anti-diversity manifesto (but might be better termed an internal memo) that was leaked and then went viral. The document can be found here. I have not dug deeply into the details, but my impression is that Damore attempted a fairly academic unpacking of the issue of gender differences in the workplace as they conflicted with institutional policy only to face a hard-set ideology that is more RightThink than truth. In Damore’s case, the truth did set him free — free from employment. Even the NY Times recognizes that the Thought Police sprang into action yet again to demand that its pet illusions about society be supported rather than dispelled. These witch hunts and shaming rituals (vigilante justice carried out in the court of public opinion) are occurring with remarkable regularity.

In a day and age where so much information (too much information, as it turns out) is available to us to guide our thinking, one might hope for careful, rational analysis and critical thinking. However, trends point to the reverse: a return to tribalism, xenophobia, scapegoating, and victimization. There is also a victimization Olympics at work, with identity groups vying for imaginary medals awarded to whoever’s got it worst. I’m no Pollyanna when it comes to the notion that all men are brothers and, shucks, can’t we all just get along? That’s not our nature. But the marked indifference of the natural world to our suffering as it besets us with drought, fire, floods, earthquakes, tsunamis, hurricanes, tornadoes, and the like (and this was just the last week!) might seem like the perfect opportunity to find within ourselves a little grace and recognize our common struggles in the world rather than add to them.

According to Hal Smith of The Compulsive Explainer (see my blogroll), the tragedy of our time is, simply put, failed social engineering. Most of his blog post is quoted below:

Americans, for example, have decided to let other forces manage their nation — and not let Americans themselves manage it. At least this is what I see happening, with the election of Trump. They have handed the management of their country over to a man with a collection of wacky ideas — and they feel comfortable with this. Mismanagement is going on everywhere — and why not include the government in this?

This is typical behavior for a successful society in decline. They cannot see what made them successful, has been taken too far — and is now working against them. The sensible thing for them to do is back off for awhile, analyze their situation — and ask “What is going wrong here?” But they never do this — and a collapse ensues.

In our present case, the collapse involves a global society based on Capitalism — that cannot adapt itself to a Computer-based economy. The Software ecosystem operates differently — it is based on cooperation, not competition.

Capitalism was based on just that — Capital — money making money. And it was very successful — for those it favored. Money is still important in the Computer economy — people still have to be paid. But what they are being paid for has changed — information is now being managed, something different entirely.

Hardware is still important — but that is not where the Big Money is being made. It is now being made in Computers, and their Software.

I’m sympathetic to this view but believe that a look back through history reveals something other than missed opportunities and too-slow adaptation as we fumbled our way forward, namely, repeated catastrophic failures. Such epic fails include regional and global wars, genocides, and societal collapses that rise well above the rather bland term mismanagement. A really dour view of history, taking into account more than a few truly vicious, barbaric episodes, might regard the world as a nearly continuous stage of horrors from which we periodically take refuge, and the last of these phases is drawing quickly to a close.

The breakneck speed of technological innovation and information exchange has resulted not in Fukuyama’s mistakenly exuberant “end of history” (kinda-sorta winning the Cold War but nevertheless losing the peace?) but instead an epoch where humans are frankly left behind by follow-on effects of their own unrestrained restlessness. Further, if history is a stage of horrors, then geopolitics is theater of the absurd. News reports throughout the new U.S. presidential administration, still less than 6 months in (more precisely, 161 days or 23 weeks), tell of massive economic and geopolitical instabilities threatening to collapse the house of cards with only a slight breeze. Contortions press agents and politicized news organs go through to provide cover for tweets, lies, and inanities emanating from the disturbed mind of 45 are carnival freak show acts. Admittedly, not much has changed over the previous two administrations — alterations of degree only, not kind — except perhaps to demonstrate beyond any shadow of doubt that our elected, appointed, and purchased leaders (acknowledging many paths to power) are fundamentally incompetent to deal effectively with human affairs, much less enact social engineering projects beyond the false happiness of Facebook algorithms that hide bad news. Look no further than the egregious awfulness of both presidential candidates in the last election coughed up like hairballs from the mouths of their respective parties. The aftermath of those institutional failures finds both major parties in shambles, further degraded than their already deplorable states prior to the election.

So how much worse can things get? Well, scary as it sounds, lots. The electrical grid is still working, water is still flowing to the taps, and supply lines continue to keep store shelves stocked with booze and brats for extravagant holiday celebrations. More importantly, we in the U.S. have (for now, unlike Europe) avoided repetition of any major terrorist attacks. But everyone with an honest ear to the ground recognizes our current condition as the proverbial calm before the storm. For instance, we’re threatened by the first ice-free Arctic in the history of mankind later this year and a giant cleaving off of the Larsen C Ice Shelf in Antarctica within days. In addition, drought in the Dakotas will result in a failed wheat harvest. Guy McPherson (in particular, may well be others) has been predicting for years that abrupt, nonlinear climate change when the poles warm will end the ability to grow grain at scale, leading to worldwide famine, collapse, and near-term extinction. Seems like we’re passing the knee of the curve. Makes concerns about maladaptation and failed social engineering pale by comparison.

When I first wrote about this topic back in July 2007, I had only just learned of the Great Pacific Garbage Patch (and similar garbage gyres in others oceans). Though I’d like to report simply that nothing has changed, the truth is that conditions have worsened. Some commentators have rationalized contextualized the issue by observing that the Earth, the environment, the ecosphere, the biosphere, Gaia, or whatever one wishes to call the natural world has always been under assault by humans, that we’ve never truly lived in balance with nature. While that perspective may be true in a literal sense, I can’t help gnashing my teeth over the sheer scale of the assault in the modern industrial age (extending back 250+ years but really getting going once the steam engine was utilized widely). At that point, production and population curves angled steeply upwards, where they continue point as though there be no biophysical limits to growth or the amount and degree of destruction that can be absorbed by the biosphere. Thus, at some undetermined point, industrial scale became planetary scale and humans became terraformers.

News reports came in earlier this month that the remote and uninhabited (by humans) Henderson Island in the Pacific is now an inadvertent garbage dump, with estimates of over 17 tons of debris littering its once-pristine shores.

17hendersonisland1-superjumbo

This despoliation is a collateral effect of human activity, not the predictable result of direct action, such as with the Alberta Tar Sands, another ecological disaster (among many, many others). In the U.S., the Environmental Protection Agency (EPA) describes its mission as protecting human health and the environment and has established a Superfund to clean up contaminated sites. Think of this as a corporate subsidy, since the principal contaminators typically inflict damage in the course of doing business and extracting profit then either move on or cease to exist. Standard Oil is one such notorious entity. Now that the EPA is in the process of being defunded (and presumably on its way to being deauthorized) by the current administration of maniacs, the ongoing death-by-a-thousand-cuts suffered by the natural world will likely need to be revised to death-by-millions-of-cuts, a heedless acceleration of the death sentence humans have set in motion. In the meantime, industry is being given a freer hand to pollute and destroy. What could possibly go wrong?

If all this weren’t enough, another development darkened my brow recently: the horrific amount of space debris from decades of missions to put men, communications and surveillance satellites, and (one would presume) weapons in orbit. (Maybe the evil brainchild of inveterate cold warriors known unironically as “Star Wars” never actually came into being, but I wouldn’t place any bets on that.) This video from the Discovery Network gives one pause, no?

Admittedly, the dots are not actual size and so would not be as dense or even visible from the point of view of the visualization, but the number of items (20,000+ pieces) is pretty astonishing. (See this link as well.) This report describes some exotic technologies being bandied about to address problem of space junk. Of course, that’s just so that more satellites and spacecraft can be launched into orbit as private industry takes on the mantle once enjoyed exclusively by NASA and the Soviet space program. I suppose the explorer’s mindset never diminishes even as the most remote places on and now around Earth are no longer untouched but human refuse.

From the not-really-surprising-news category comes a New Scientist report earlier this month that the entire world was irradiated by follow-on effects of the Fukushima disaster. Perhaps it’s exactly as the article states: the equivalent of one X-ray. I can’t know with certainty, nor can bupkis be done about it by the typical Earth inhabitant (or the atypical inhabitant, I might add). Also earlier this month, a tunnel collapse at the Dept. of Energy’s Hanford nuclear waste storage site in Washington State gave everyone a start regarding possible or potential nearby release of radiation. Similar to Fukushima, I judge there is little by way of trust regarding accurate news or disclosure and fuck all anyone can do about any of it.

I’m far too convinced of collapse by now to worry too much about these Tinkerbells, knowing full well that what’s to come will be worse by many magnitudes of order when the firecrackers start popping due to inaction and inevitability. Could be years or decades away still; but as with other aspects of collapse, who knows precisely when? Risky energy plant operations and nuclear waste disposal issues promise to be with us for a very long time indeed. Makes it astonishing to think that we plunged full-steam ahead without realistic (i.e., politically acceptable) plans to contain the problems before creating them. Further, nuclear power is still not economically viable without substantial government subsidy. The likelihood of abandonment of this technological boondoggle seems pretty remote, though perhaps not as remote as the enormous expense of decommissioning all the sites currently operating.

These newsbits and events also reminded me of the despair I felt in 1986 on the heels of the Chernobyl disaster. Maybe in hindsight it’s not such a horrible thing to cede entire districts to nature for a period of several hundred years as what some have called exclusion or sacrifice zones. Absent human presence, such regions demonstrate remarkable resilience and profundity in a relatively short time. Still, it boggles the mind, doesn’t it, to think of two exclusion zones now, Chernobyl and Fukushima, where no one should go until, at the very least, the radioactive half-life has expired? Interestingly, that light at the end of the tunnel, so to speak, seems to be telescoping even farther away from the date of the disaster, a somewhat predictable shifting of the goalposts. I’d conjecture that’s because contamination has not yet ceased and is actually ongoing, but again, what do I know?

On a lighter note, all this also put me in mind of the hardiness of various foodstuffs. God knows we consume loads of crap that can hardly be called food anymore, from shelf-stable fruit juices and bakery items (e.g., Twinkies) that never go bad to not-cheese used by Taco Bell and nearly every burger joint in existence to McDonald’s burgers and fries that refuse to spoil even when left out for months to test that very thing. It give me considerable pause to consider that foodstuff half-lives have been radically and unnaturally extended by creating abominable Frankenfoods that beggar the imagination. For example, strawberries and tomatoes used to be known to spoil rather quickly and thus couldn’t withstand long supply lines from farm to table; nor were they available year round. Rather sensibly, people grew their own when they could. Today’s fruits and veggies still spoil, but interventions undertaken to extend their stability have frequently come at the expense of taste and nutrition. Organic and heirloom markets have sprung up to fill those niches, which suggest the true cost of growing and distributing everyday foods that will not survive a nuclear holocaust.

As I read into Fingerprints of the Gods by Graham Hancock and learn more about antiquity, it becomes clear that weather conditions on Earth were far more hostile then (say, 15,000 years ago) than now. Looking way, way back into millions of years ago, scientists have plotted global average temperature and atmospheric carbon, mostly using ice cores as I understand it, yielding this graph:

co2-levels-over-time1

I’ve seen this graph before, which is often used by climate change deniers to show a lack of correlation between carbon and temperature. That’s not what concerns me. Instead, the amazing thing is how temperature careens up and down quickly (in geological time) between two limits, 12°C and 22°C, and forms steady states known at Ice Age Earth and Hot House Earth. According to the graph, we’re close to the lower limit. It’s worth noting that because of the extremely long timescale, the graph is considerably smoothed.
