  • Oil Now on 65 Miles of Shoreline; BP Will Try a “Top Kill” to Stop the Leak | 80beats

    PelicanOilThis week BP will try one more time to stop its massive leak in the Gulf of Mexico. The “top kill” plan that was supposed to go into action on Sunday will now commence on Wednesday, the company says.

    The process will involve pumping heavy fluids down two three-inch lines placed inside the wellhead. If successful, the fluids will temporarily stop the oil rush, which would then allow operators to seal the opening with cement. The wellhead, officials say, will never be used again for oil drilling [Christian Science Monitor].

    Just like the containment dome, though, a top kill has never been attempted on a leak gushing so far below the surface of the water—5,000 feet. But with BP’s other attempts ending in failure, this looks like the best shot the company has to stop the flow in a short term.

    As BP prepares this operation, the simmering anger at the company has seeped up to the higher levels of the U.S. government. Rear Admiral Mary Landry, who has been coordinating the Coast Guard’s response with BP, finally started to sound annoyed with the company’s actions—or lack thereof—as 65 miles of American shorelines have now been hit by oil, coating pelicans in Louisiana that were just removed from the endangered species list six months ago.

    Landry also criticized BP for allowing some equipment that could aid in efforts to block or clean up the spreading oil slick to sit unused, even as oil is washing up onto the Gulf Coast. “There is really no excuse for not having constant activity,” Landry said [New Orleans Times-Picayune].

    Other government officials, like Secretary of the Interior Ken Salazar, were more direct:

    In a news conference on Sunday outside the BP headquarters in Houston, Mr. Salazar repeated the phrase that the government would keep its “boot on BP’s neck” for results. He also said the company had repeatedly missed deadlines and had not been open with the public. Mr. Salazar added, “If we find they’re not doing what they’re supposed to be doing, we’ll push them out of the way appropriately” [The New York Times].

    The AP reports that the Justice Department is gathering information about the spill, but the White House wouldn’t say this weekend whether it intended to open a criminal investigation of BP. In the meantime, anger levels continue to rise as the oil slick gets wider.

    On Saturday, the tensions between BP and local authorities came to a boiling point in Jefferson Parish, when local officials declared they were going to commandeer 40 boats of fishermen who had signed up to help with the spill but had since remained idle. They had spotted oil moving past the shoreline beaches through passes into Barataria Bay, which is surrounded by wildlife-rich wetlands [The New York Times].

    But what of the EPA demand we covered on Friday, that BP must find an alternative chemical dispersant and switch within a few days? It seems that wasn’t such rigid ultimatum after all. BP replied over the weekend that no, they’d just as soon keep using the worrisome dispersant they’ve been using all along. The EPA flipped again and said that it might not force the switch.

  • How the Swedes became white | Gene Expression

    vikingsA few weeks ago I read Peter Heather’s Empires an Barbarians, but I had another book waiting in the wings which I had planned to tackle as a companion volume, Robert Ferguson’s The Vikings: A History. Heather covered the period of one thousand years between Arminius and the close of the Viking Age, but his real focus was on the three centuries between 300 and 600. It is telling that he spent more time on the rise and expansion of the domains of the Slavic speaking peoples than he did on the Viking assaults on Western civilization; an idiosyncratic take from the perspective of someone writing to an audience of English speakers. But within the larger narrative arc of Empires and Barbarians this was logical, the Slavs were far closer to the relevant action in terms of time and space than the Scandinavians who ravaged early medieval rather than post-Roman societies (where the latter bleeds into the former is up for debate). In Heather’s narrative the Viking invasions were a coda to the epoch of migration, the last efflorescence of the barbarian Europe beyond the gates of Rome before the emergence of a unified medieval Christian commonwealth. And these are the very reasons that Robert Ferguson’s narrative is a suitable complement to Peter Heather’s. Ferguson’s story begins after the central body of Heather’s, and most of its dramatic action is outside of the geographical purview of Empires and Barbarians. In The Vikings the post-Roman world has already congealed into the seeds of what we would term the Middle Ages, and it is this world which serves as the canvas upon which the Viking invasions are painted. Aside from what was Gaul the world of old Rome is on the peripheries of Ferguson’s narrative.


    It was refreshing to me that the author of The Vikings makes a concerted effort toward balance (despite what I perceive to be his clear identification as a scholar of the Vikings with the Scandinavian peoples of the period in a broadly sympathetic sense). He explicitly lays out the tendency of previous scholars and commentators to lean excessively toward the Vikings or their victims in weighing the veracity of narratives, or ascribing a moral high ground to one particular vantage point. More common perhaps of the two is the tendency toward depicting the Vikings in the manner that Christians of the time viewed them, as an avaricious force of nature whose role was to punish civilization for its sins (in our era we may secularize the events, but the tendency toward viewing barbarians as deterministic elements operating upon civilized agents often remains). As a reaction against such a one-sided classic framing some scholars have reinterpreted the Vikings as well-armed traders who were simply misunderstood and libeled by their Christian antagonists. In this telling the Vikings sacked the monasteries because they were locked out of trade networks due to their status as cultural outsiders. Raiding was simply a substitute for trading. Both of these normative and simplified frames really belong in a “First Book” for children; individual humans are more complex than that, and history is more complex than individual humans. When it comes to history true objectivity is probably impossible, but admitting that past workers have had strong biases is probably a good place to start.

    In The Vikings Robert Ferguson regales us with in large part is an ancient “Clash of Civilizations.” He notes that the sources invariably distinguish between Christians and Heathens as opposed to English and Norse (or Franks and Norse), and in keeping with this he lays out a dichotomy between Christian civilization and “Heathendom.” Our view of the past is colored by the reality of the victory of the former against the latter, but the slow and inexorable expansion of the arc of Christian civilization among the Scandinavians which we view in hindsight as a process which has a clear terminus actually took nearly five centuries, with most of the Christian success at the expense of the Heathens occurring within the last one hundred and fifty years (despite missionary endeavors across the whole period, mostly out of Bremen and Hamburg). Ferguson convincingly argues the Heathens had a sense of their own identity, distinctiveness, and even superiority, in relation to the Christians during this period when Scandinavia was outside of the boundaries of the West. This is actually most evident in Muslim sources, who had more distance from the pagan Scandinavian culture and so could view it with more ethnographic third party objectivity (the Muslim sources were often engaging in trade or diplomacy). They report for example the argument of one Scandinavian that his peoples’ practice of burning was far superior to the inhumation that was the norm among Christians, Muslims and Jews, because the transition to the afterlife is far faster with the rapid disintegration of the body, as opposed to decomposition and later consumption by “worms” (this critique is almost a trope from what I can tell when it comes to the perception of peoples who burn the bodies of their dead of the customs of those who bury). What we see here is not some deep philosophical sense of superiority, but the native chauvinism and ethnocentrism which most peoples have in regards to their own mores and traditions. Heathens were not simply a negation of Christian civilization, in contemporary parlance they were an indigenous folk of northern Europe resisting the expansion of an international and globalist Christian culture.

    A more historically grounded rationale for Heathen sense of distinction from Christians, and their hostility toward Christian civilization generally, is the real history of forced conversion which they experienced at the hands of Christian powers. In particular the author points to the conquest and conversion of the Saxons by Charlemagne as a turning point. These German tribes were on the margins of the Scandinavian world, so word of their oppression, and ultimate destruction of their native traditions at the hands of outsiders, must have percolated to the north (Saxon warriors took refuge among the Danes). In The Vikings the author explicitly suggests that the savagery of the Norse in their assaults on Christian monasteries may be connected to the fear and hostility engendered toward the Christian religion by these instances of mass forced conversion and aggression. The analogy here may be the Boxer Rebellion, where indigenous anger at the expansion of foreign powers and their cultural mores exploded in targeted violence. The brutal nature of Christian conversion is highlighted vividly by the anecdote of Olaf Tryggvason, Norway’s first explicitly Christian king, threating to kill the three year old son of a British Norse warlord in front of his father unless he and his people submitted to immediate baptism. Ferguson observes that the Christian chronicler records this action approvingly, but certainly this sort of behavior on the part of Christians against the Heathen Scandinavians integrated over centuries may account for some of the motive for the violence of the Vikings against Christian holy sites and institutions. For the Heathen the Christian was the threatening Other, and so thoroughly dehumanized.

    But the relationship of Heathendom to Christian civilization, and the local and indigenous Scandinavian tradition to global cultures, was not simply one of hostility and mutual exploitation and brutality. One of the interesting aspects of the Scandinavian expansion of the 8th to 10th centuries is its geographic range. Their presence on the northwestern fringes of Europe as Vikings is well known in the English speaking world. But Scandinavian raiders were prominent in Muslim Spain, and even broke into the Mediterranean. Of more permanence was the influence and power of a group known as the Rus across the vast swaths of land from the Baltic to the Caspian. It seems probably that Slavicized Rus were the core of the early polities of Novgorod and Kiev, which later gave rise to Russian identity. In the generation of the grandfather of Vladimir I of Kiev, credited with bringing the Russians to Christianity, the elite of the Kiev seemed invariably to possess Scandinavian names. This was an empire of war, trade and colonization along the fringe of early medieval Christendom, and sweeping down toward the margins of the world of Islam on the Caspian.

    Why the expansion? A conventional explanation has been overpopulation. This doesn’t hold water, in pre-modern societies Malthusian dynamics were always at play. That is, growth was very slow because high fertility was counterbalanced by high mortality. In the event of an epidemic there may be a period when demographic expansion is possible, but these would be transient phases. There is evidence that across northern Europe in the first millennium there was underway a transition toward more productive forms of agriculture which allowed for a larger basal population, but this was a general feature of European societies, not one restricted to Scandinavia. In fact the increase in population was probably most pronounced in two regions to which the Vikings were most drawn to plunder: northern France and the Low Countries. And this may explain a cause for the Viking expansion, they sought wealth, and more wealth was to be gotten in the Christian lands than within Heathendom.

    Ferguson seems to posit both push and pull dynamics. The push dynamics had to do with a restructuring of Scandinavian society in the centuries before 1000. This involved the emergence of more powerful apex leaders who marginalized the numerous figures lower down on the status hierarchy. A shift toward a more centralized political order would have concentrated power and wealth in the hands of few at the expense of the many. In this case the many in fact is going to be a minority of the population, free males who are part of the political and military class, and who collect rents from peasants and extract labor out of their human property (thralls). This dynamic is not conjecture, the migration of warlords to the British Isles in the wake of the rise of Harald I of Norway is apparently documented. The rise of a Great Man seems to invariably come at the expense of many less great men in a zero sum world. Similarly, the arrival of the reputed sons of Ragnar Lodbrok to British Isles may have had to do with political events in Denmark in the decades before the reemergence of the Jelling dynasty. But this push process can not be decoupled from wider social and historical events. In other words, the parameter is not purely endogenous. Rather, the events within Scandinavia were strongly shaped by the emergence of a global political and economic order which Heathendom was a participant, if at times a reluctant and belligerent party. Scandinavia’s political connection to other parts of Europe was clear even in the Late Antique period; Scandinavian warriors and kings were a presence at the courts of post-Roman figures such as Theodoric the Great of the Ostrogoths. Conversely, German peoples who were on the losing side in the post-Roman scramble would on occasion exercise an exit option of migration back to their homelands, which sometimes included southern Scandinavia.

    So the elites of Scandinavia were aware of the wider world well before the Viking Age, and certainly had a sense of the possibilities of unitary political systems as far back as Classical Antiquity. There is also a great deal of circumstantial evidence that the elaborated nature of late Scandinavian paganism has much do with the model which Christianity presented as a complex institutional religion. The mythos around Balder has often be assumed to have been influenced by the Christian mythos around Jesus, but we need not hinge our inference on literary recollections which may have been influenced by later generations who were Christian. There is a great deal of evidence from the Wends and Lithuanians, who persisted in their paganism even longer than the Scandinavians, of the development of a pagan “anti-Christianity” around which their ethnically based polities could coalesce (there are references to a shadowy pagan equivalent to the pope among the later Lithuanians during the apogee of their empire in the 14th century). In Empires and Barbarians and Empires of the Silk Road the authors argue that the emergence of more complex and large scale political and social orders beyond the limes of settled agricultural civilizations dominated by literate elites was a reaction to developments within the ecumene. For the nomadic confederations of the east Eurasian steppe it was the unification of China under Qin Shi Huangdi. For the Germanic tribes beyond the Roman limes it was Rome itself, which periodically erupted beyond its borders to engage in punitive expeditions (archaeology has been uncovering unrecorded Roman expeditions into Germania in the century following the defeat of Varus’ legions). For the Scandinavians it seems to have been the rise of the Frankish political order, and particular the Carolingian dynasty, which annexed and Christianized the lands of the Saxons just to the south of Scandinavia which served as a spur to their social and political revolution.

    With the rise of a powerful Christian state to its south bent on cultural, political and economic conquest and assimilation, there would naturally have been greater self-consciousness of the peoples of Scandinavia in regards to their indigenous traditions. Despite periodic attempts by powerful aristocrats and kings from the 9th century on there was stubborn resistance from sub-elites in acceding to the shift from their customary cults to the Christian religion. I think a little bit of Homo economicus in terms of rational behavior might allow us to explain this disjunction between the apex elites in the form of kings, and sub-elites. In societies without a tradition of autocracy under a singular individual a broad level of consent from numerous sub-elites of modest means was necessary for an individual to rise to kingship. But these sub-elites may not have been economically advanced enough to see any gains in integration into a globalized political order where their nations were part of a commonwealth of Christian monarchies. Rather, they perceived a dispossession of their traditional cultic roles under the aegis of a transnational church apparatus (albeit, one which operationally co-opted local elites rather rapidly after Christianization by assimilating them into the clerical superstructure). Put more simply, there was great gain to monarch in becoming part of the international order, but little for the population as a whole, even among the lesser nobility, who were dependent on local rents, not international trade or conquest.* In the world of the Malthusian trap the lives of the peasantry would be little changed by an ideological shift on high, so they were of no consequence (in fact, Protestant Reformers routinely complained that the Church had left the peasantry of many nations barely Christian in anything but name).

    Of course there was a way for sub-elites to become wealthy rather rapidly: steal from wealthier societies instead of depending on protection money (rent) from your poor peasants. It is notable that the Viking Age spans the period which saw the decline of Charlemagne’s political system, but before the emergence of the medieval antecedents of the nation-states which would crystallize in the early modern period. It was also during this time that northern France and the Low Countries, and to a lesser extent England, saw an expansion of aggregate wealth because of improved agricultural techniques and tools such as the three field system and the mould-board plough as well as the beginning of the Medieval Climatic Optimum. The idea that one could steal wealth was not an innovation of the Vikings, Charlemagne’s campaigns were in part motivated by the need to generate plunder to satisfy his vassals. Similarly the Roman wars of conquest were magnificently lucrative for the Republic’s aristocracy, and it can be argued that the wealth stolen from the early conquests were critical in maintaining Roman dynamism. It is possible that no imperial conquest after that of Dacia in the early second century was profitable, and it is this period which saw the high water mark of the Roman civilization, the century of the Good Emperors.

    Shifting back to the Vikings, the model then is rather easy to summarize. Step 1, Western civilization in the form of the Christian Frankish polities push north and east, toward the fringes of Scandinavia. Step 2, this results in a coalescence of counter-identities among the populations which are being impinged upon and destabilized. In the case of the Saxons under Widukind and his confederates resistance was futile, and they were absorbed into the new Christian order (in fact, Saxon Christian monarchs in the 10th century placed so much pressure on pagan Denmark that it probably facilitated the final absorption of the Jelling monarchy into the Christian state system as another lever to maintain their independence). But for populations further out, as in Scandinavia, or in the eastern marches which were inhabited by the West Slavs, the Frankish expansion lost its steam before it could fully absorb them. This left these populations in a stronger position in terms of the ability to engage in coordinated action than before, because they now had a common identity in the face of Christian expansion as well as more powerful military leaders who had come to the fore in the face of the threat from the alien superpower. Step 3, the collapse of the Frankish Empire into sub-states leaves the margins of Christian civilization more vulnerable as none of these polities now can bring to the fore overwhelming force against small groups of raiders. Step 4, the integrative phase within the cultures outside of Christian civilization combined with wealth differentials across civilizational boundaries produce the convulsions which result in the out-migration of militarized sub-elites. They are well aware enough of wealthier societies to understand the cost vs. benefit for them, and they lack ideological affinity with those wealthier societies, so their actions are unencumbered by any moral or ethical framework. In other words, Heathens and Christians exhibited a much less robust sense of empathy toward each other than they did those from within their own culture, so the depredation of one upon the other was particularly savage and utility maximizing (in the Middle Ages the paganism of many Baltic populations was somewhat convenient because Christians were allowed to enslave pagans, making them extremely economically profitable as tenants since they lacked human rights). Step 5, the military assault upon civilization by the barbarians eventually peters out and results in the assimilation to a great extent of the barbarians into the civilized order. Once the windfall wealth is spent the inevitable consequence is the absorption of the less numerous and organized society into the more numerous and organized one.

    These steps in general seem broadly applicable to the post-Roman and post-Han dynasty periods in Europe and China as well. In the end the barbarian societies which initially have a strong aversion to the civilized societies whom they oppose, are oppressed by, and often conquer, became ideologically identified with those societies. This generally occurs through religion, but also often through other aspects of assimilation in identity (e.g., the Franks became the Latinate French, the barbarian groups in China often became Chinese speaking and switch their ethnic identity to Han). The main exception to this general trend which I can think of is the case of the Arab Muslim conquest, and in this case the barbarians brought with them an ideology which was robust and in large part mimicked that of civilized societies.**

    We do not live in the world of the Vikings, where Malthusian parameters reign supreme, elites live off the toil of peasants, and religion is a matter of life and death (excepting parts of the Muslim world like Sudan or the Communist world like North Korea). But cultural identity still matters. Today when we speak of “indigenous people” we allude to relics of a bygone age, small-scale cultures on the margins. But as recently as one thousand years ago vast swaths of Europe, in particular its north and east, were populated by indigenous peoples, attempting to preserve their ancient traditions and customs in the face of Christian globalization. More broadly, in the period between 500 and 1000 numerous peoples outside of the Eurasian Rimland, to the north, east and west, contingent upon the point of reference, were affected by the expansion of ideological systems from the Rimland civilizations, which arrived through military, demographic and economic means. The Gauls of France lost almost all unique aspects of their identity, their language, their religion, even their name for themselves. Other populations, such as the Germans and the Turks retained much of their identity, and profited through integration into a broader civilization through which they channeled their cultural influence. But this process took centuries, and was not without tumult. The Viking Age was not an act of God, it was not an isolated case. It was rather an instance of a general process whereby the cultural configurations of the World Island were assigned in a manner which we would recognize today, with civilizational boundaries hardening into forms which were robust to exogenous shocks.

    One interesting aesthetic observation which I will take away from The Vikings: A History is that the peoples of the north were generally tattooed and made recourse to eye shadow and other such body adornment. Christian sources point to this only in a negative fashion, that is, the practice is explicitly banned for Christians in the north, presumably because this was previously a common practice (as well as the consumption of horseflesh, which had cultic significance). But the Muslim sources describe the obsession of the northern people with aesthetic detail thoroughly, and it notable to me that Otzi the Iceman was also tattooed. These sorts of markings have obvious functional purposes, in identifying a member of one tribe from another in an indelible fashion, but they also are perhaps reflective of societies where aesthetic expression was personalized and small scale. Their Pantheons were their bodies. This is familiar to us today from small-scale societies and small indigenous groups, who maintain these traditions and this outlook. It was only 1,000 years ago that many European peoples were still vigorously adhering to these folkways, before they became Christian, and therefore white.

    Note: I have avoided discussing the likely brisk trade between Scandinavia and the pre-Muslim and post-Muslim Middle East, which is vividly documented in coinage. The blockage of this trade by steppe powers such as the Khazars has been argued to be one of the major motives for the Rus exploration of the Dnieper and Volga river systems. It’s an interesting story, but takes us a bit afar, though illustrates another economic motive in the barbarian expansion.

    Additionally, in keeping with the tone of the book I have exhibited some broad empathy to the Viking societies transformed beyond recognition by assimilation into European society around 1000. But I will add into the record that as a personal normative preference I believe that cultural homogeneity, in particular in language and religion, can often be beneficial in generating economic and ethical economies of scale. Though I believe that there are diminishing returns on the margin here (there is harm when police states attempt to impose one language and one religion on the whole populace through extreme tactics).

    * In the late Roman Empire the aristocratic nobility remained pagan far longer than the Emperors and the service nobility dependent upon the Empire, as opposed their personal wealth.

    ** There is a great deal of debate as to how Islam arose, and some scholars argue that Islam is actually a relatively late development out of a sect of Arab Christians. If this is true the Islamic exception is no exception at all, but serves as an alternative history where the Goths remain Arian and assimilate their Roman subjects to their religion and language.

  • What is the Air Force doing with space? | Bad Astronomy

    The military uses for space travel are legion: besides the obvious utility of being able to launch weapons much more quickly at a target, it can be used to prevent military action through advanced intelligence gathering.

    X-37_uprightThe Air Force has long been in the vanguard of space based operations, but of course much of that is secret (and rightly so). I had heard of the X-37 B — aka the Flying Twinkie — for some time, but since there was so little info on it I didn’t write anything. But interestingly, through Slashdot I learned that amateur satellite spotters have seen the X-37 B from the ground. Not many people know you can spot all sorts of satellites from your front yard; all you need in most cases is knowledge of your latitude and longitude and a website with satellite listings.

    Info about the X-37 B is relatively tight, so it’s unclear what it’s being tested for. Surveillance is assured, since any satellite can be used for that. The Air Force says it has no offensive capabilities — I wonder if they mean the test shot launched last month, or the X-37 B itself — but it does have a payload capability for small satellites, and can be operated in orbit for at least 9 months. Its orbit takes it from -40° to +40° latitude. Go look at a globe and see what countries lie in that range that might be of interest to the military…

    airforce_scramjetAlso of interest is that the Air Force is planning a test launch of a hypersonic scramjet called the X-51A, an aircraft capable of flight at speeds of at least Mach 6 — about 7000 kph! That launch may happen as soon as May 25. Scramjets are fiercely complex technologically; while technically rockets, they use oxygen from the air instead of carrying it on board. This saves a lot of mass, and has a huge range of uses; military of course, but also civilian uses for aircraft.

    I saw an early version of a scramjet a few years ago, and was awed by it; Mach 6 is fast, and these things have an upper speed that may exceed that by quite a bit. When this tech tests out, it may revolutionize the whole world. Imagine getting from the US to Japan in an hour, or basically from any point in the world to any other point in just a few of hours! In a hundred years, statements like that may seem quaint, but for now, it’s the future.

    Some people may knee-jerk and think the military will abuse this tech, but I understand that developing and using this sort of thing can help prevent conflicts… and may lead to a revolution as profound as the invention of the car, the airplane, and the spaceship. I hope the military can get all this working. I still have hopes that the near future will look like the one I read about when I was a kid.

  • Dear Entrepreneurs: There’s No Money in Geoengineering | The Intersection

    On the left wing, there’s this strange notion that geoengineering is a new corporate obsession. Scientists interested in the topic are accused of being part of a “geoengineering lobby” that wants to mess with the planet for fun and profit. Alas, there’s no evidence to support this idea. In fact, as recent Point of Inquiry guest Eli Kintisch reports over at CNN Money, government regulations so far have quashed those few attempts to profit off of geoengineering that have made it to the trial stage.

  • The Cretaceous Comes To My Front Yard | The Loom

    walking turtle600Sunday morning was cool and foggy, and so we were not surprised to discover the garden full of craters and trenches. A snapping turtle the size of a manhole cover was busy laying her eggs.

    This is an annual ritual in this part of New England. The first time I encountered a snapping turtle here, not long after we had moved into our house, I was terrified. Our children were toddlers, old enough to run but not old enough to know they should stay away from animals that can snap off your finger. Somehow I had to get the turtle out of my yard and back into the creek that runs behind our house. With no experience in turtle-wrangling, I decided to get a broomstick. I tapped the turtle on its shell, to signal that I wanted it to leave. It looked up at me with supreme indifference.

    My helplessness made me hallucinate. I feared the turtle was going to break into the house somehow and eat our cats. I called our town’s animal control line, and ended up talking to a policeman. He gave me a suprisingly detailed lecture on the natural history of the snapping turtle. On cool, foggy mornings in late spring, he explaned, females emerge from streams and wetlands to bury their eggs in the soft earth. They take care of their business in about an hour, and then they leave. He would not be coming to my house to rescue us.

    He was right. The turtle picked a lush bed of mulch and mud, near a rose bush, and laid her eggs. I stared at from the front door with my children until we got bored. When I checked back a few minutes later, it was gone. I never realized that a snapping turtle can disappear when it wants to. After a few weeks the eggs hatched. In the summer we discovred adorably vicious baby snapping turtles trying to find their way back to the water. Every spring since, the snapping turtles have returned, and we’ve gotten more comfortable with them. I don’t bother the police. Instead, we get reasonably close to the turtle to observe.

    We usually get one snapping turtle visiting us each year. We’re grateful, but we also know these visits are a shadow of a former glory. One of our neighbors, who grew up in our town, remembers armies of snapping turtles swarming up out of the creek in the spring. We live in biologically impoverished times, with constipated streams, filled-in marshes, and other assaults on the habitat of turtles in New England. Snapping turtles have been wandering out of marshes for millions of years. The oldest turtle fossils are about 220 million years old, but snapping turtles evolved much later. They belong to a 90-million-year-old lineage that also gave rise to species that span the extremes of turtle biology, from tiny mud turtles to leatherback turtles, the biggest reptiles on Earth, which swim across oceans.

    Laying turtle440This morning’s visitation was particularly mesmerizing, because the snapping turtle angled her body in such a way that we could see her eggs drop into the hole she had dug. They were the size and shape of eyeballs. As the eggs eased out of her cloaca, she tapped them with her right back foot into the hole, like a soccer player giving a ball the extra kick it needed to reach the goal. One after another, the eggs tumbled out. We counted a dozen, but snapping turtles can lay dozens more at a time. They pick these nests carefully. They chose these spots for their temperatures. Like many other turtle species, snapping turtles end up male or female depending on the temperature. At low and high temperatures, they produce females; at intermediate temperatures, they make males. Snapping turtles don’t have thermometers, but they have evolved a simple rule of thumb (or claw). They seek out soft, sandy soil, which tends to be the right temperature to produce a mix of males and females.

    Unfortunately, we may be setting ecological traps for the turtles. They sometimes lay eggs in yards underneath planted trees or near houses. The shadows cool the temperatures compared to sites they pick in natural habitats. On the other hand, global warming may send them in the other direction. In either case, we may cause them to make too few males. And because they live so long (they can live 40 years), they will be slow to evolve new preferences. I hope that my grandchildren will be able to come see snapping turtles rip up our garden, but I cannot be sure.

    Here’s the report that (I understand) airs tonight:
    Climate scientist Michael Mann has received hundreds of them — threatening e-mails and phone calls calling him a criminal, a communist or worse. “6 feet under, with the roots, is were you should be,” one e-mail reads. “How know 1 one has been the livin p*ss out of you yet, i was hopin i would see the news that you commited suicide, Do it.” “I’ve been called just about everything in the book,” Mann, who runs of the Earth System Science Center at Penn State University, told ABC News. “It’s an attempt to chill the discourse, and I think that’s what’s most disconcerting.” Mann is not the only one. The FBI says it’s seeing an uptick in threatening communications to climate scientists. Recently, a white supremacist website posted Mann’s picture alongside several of his colleagues with the word “Jew” next to each image. One climate scientist, who did not wish to be identified, told ABC News he’s had a dead animal left on his doorstep, and now sometimes travels with bodyguards. “Human-caused climate change is a reality,” Mann said. “There are clearly some who find that message inconvenient, and unfortunately they appear willing to turn to just about …

The session begins with an overview of the “theory” of science communication–why we must do it better, what the obstacles are, and how a changing media environment makes it much tougher than it was during the era when the dude at right was so popular (the same era when the dude at *top* right was about to deregulate the media…). Then, the session goes into a media “how to”–rules for interacting with journalists, media do’s and don’ts, and an overview of various key communication “technologies,” such as framing. Finally, it ends with a role playing in which the scientists get to try out their chops in a Colbert-style interview, and see if they can stay on message while traversing the very rockiest of media seas. I get the sense there is an increasing demand for this kind of training, which is often not provided in the standard science graduate curriculum. The hunger seems especially strong among the younger set of scientists. Why? Well, consider the write up for another all day sci comm boot camp I did at Princeton …


  • “Weedy” mice dominate a warming world while other small mammals suffer | Not Exactly Rocket Science

    Deer_mouseToday’s mammals are facing the twin threats of a rapidly warming planet and increasingly intrusive human activity. As usual, the big species hog the limelight. The world waits on bated breath to hear about the fates of polar bears, whales and elephants, while smaller and more unobtrusive species are ignored. But smaller mammals are still vital parts of their ecosystems and it’s important to know how they will fare in a warmer world. Now, thanks to Jessica Blois from Stanford University and a hoard of new fossils, we have an idea. As they say, all this has happened before

    Around 12,000 years ago, as the Pleistocene epoch drew to a close, the mammals of North America were also dealing with multiple threats. The last Ice Age was giving way to the far warmer Holocene and at the same time, humans arrived on the scene, wiping out species after species. Some of the larger losses are familiar, such as the mammoths and ground sloths, but a new treasure trove of fossils in California’s Samwell Cave has revealed the fate of their smaller kin.

    The common wisdom suggests that small mammals are relatively resistant to extinction, because they have large litters, they breed quickly and their populations grow at incredible rates (think mice and rabbits). The Samwell fossils support this idea but they also tell us that communities of small mammals were greatly affected by natural warming nonetheless. Their diversity plummeted, they became less evenly spread, and rare species became ever rarer.

    Not everything suffered though – ‘weedy’ species took over this new landscape. The deer mice did particularly well, doubling in abundance between 16,000 and 13,000 years ago. These rodents aren’t fussy about their homes and they’re often the first into a new area. Opportunistic and adaptable, these generalists flourished under changing circumstances that flummoxed others. And their rise to power accounted for much of the fall in overall species evenness during this time. There are signs that deer mice are doing the same today.

    To Blois, it’s clear that these changes were mainly driven by climate change. As the temperature rose, so the evenness and richness of the mammal communities fell, and the first signs of falling populations coincided neatly with the very rapid warming of the Bolling-Allerod period. Individual species supported these general trends. The Western pocket gopher and the mountain beaver both went locally extinct and today, they’re found in much cooler parts of California. Blois thinks that these rodents tracked the cooler weather to other more hospitable areas.

    Meanwhile, Blois also ruled out other possible explanations. Humans invaded North America during the end of the Pleistocene, but the shifts in small mammal populations predated them by around 1,500 years. The fall of the large beasts could have altered the local vegetation, creating new landscapes for species that scurry, but these new plant communities also appeared after the small mammal communities had already started to shift. Changing climate, it seems, is the best explanation.

    Blois says that since today’s climate is changing even more quickly, our current small mammals might face a similar fate to their Pleistocene counterparts. Their communities are likely to shift towards an impoverished and uneven selection of species. In this way, they could act as a colony of furry canaries, as “harbingers of imperilled ecosystems”.

  • A skeptic needs our help | Bad Astronomy

    michaelstriebLast year, at The Amaz!ng Meeting 7, I met a young skeptic who went by the handle Nobby Nobbs on the fora. His real name is Michael Strieb, and he has Amyotrophic Lateral Sclerosis, also called ALS or Lou Gehrig’s disease. This is the same condition Stephen Hawking has.

    In Michael’s case it confined him to a wheelchair and at TAM it was very difficult for him to speak. I just read from Rebecca at Skepchick that his condition has progressed, and now it’s impossible for him to talk. His mind is healthy and sharp, but his body is making it extremely difficult to communicate.

    Because of this, a group has set up a page where people can donate so that they can buy Michael an Eye Gaze System, an incredibly cool setup where a machine can measure where his eye is pointing, and use that to guide a cursor on a computer screen, allowing Michael to once again communicate. The device costs about $3200.

    Update: Someone who knows Michael has let me know that this is not the only source of their financial need. As you can imagine, his situation can put a strain on anyone’s budget. So please give what you can, and help out a guy — and his family — who could use a little relief.

    Michael’s one of the good guys. I just sent in my donation, so please, if you can, help him out.


  • Unruly Democracy: Pictures, Videos | The Intersection

    The conference on science blogging at the Harvard Kennedy School from last month now has a lot of multimedia available. There are Flickr pictures, like this one, showing a panel comprised of myself, Jessica Palmer, Francesca Grifo of the Union of Concerned Scientists, and moderator Sam Evans: And there are also 35 YouTube vids of the entire event. I am going to post some of these over the course of the week with commentary, but for now, you can start from the intro, by Harvard’s Sheila Jasanoff, and go from there…


  • Atlantis rides above the waves | Bad Astronomy

    atlantis_iss

    The Space Shuttle Atlantis will undock from the International Space Station for the last time Sunday at 11:22 a.m. EDT (15:22 UT), and is scheduled to land at Kennedy Space Center on May 26 at 08:48 ET (12:48 UT). This image was taken during the last scheduled mission of Atlantis, still attached to the ISS as it orbits over the ocean. You can watch how it go there, too: NASA has uploaded incredible video from cameras located on the solid rocket boosters during launch.

  • Martin Gardner, 1914 – 2010 | Bad Astronomy

    I am very sad to write that Martin Gardner, a skeptical giant and genius by any standard, died today in Tulsa Norman, Oklahoma.

    Martin_GardnerWikipedia has a list of his remarkable achievements. He was a lifelong friend of James Randi, who has written a brief statement at the JREF page. I’ve heard Randi tell many a tale about him. His love for Martin was worn on his sleeve.

    I never met Martin, but he influenced my life anyway. I don’t know exactly how old I was, but I think I was in sixth grade when I found a copy of one of his many books filled with brain teasers and math puzzles. I’ve always loved puzzles, but Martin’s books showed me how to think around some problems, how to take that needed step to the side to see the solution lying beyond… and more importantly, trained me how to find the path to that solution.

    Very few people wake up one day seeing the world rationally; it’s a series of steps that takes you there. Eventually you look around and realize it, and when you look behind you you see the footsteps that brought you to that place. Off in the distance, well behind me, but at a critical point in my life, I can see where Martin gave me a nudge. It was a small push, to be sure, just a gentle poke, but with time it acquired vast leverage.

    The skeptic community mourns the loss of one of our giants, but we know we’re all better off for the time we had him here.

  • The Rikers | Bad Astronomy

    “Star Trek: The Next Generation” premiered my first year of grad school, and the last episode aired my last year. It bookended my career as a student getting a PhD in astronomy, and so it has personal meaning for me. Also, I simply loved the show. And I mean love like grown-up love; I accepted its faults as well as the times it exceeded the sum of its parts.

    On reddit, I found a link to this video, an interview with Marina Sirtis (Troi) and Jonathan Frakes (Riker), and if you’re a TNG fan, it’s a must-see. It’s simply wonderful.


    Its starts off a little goofy and fun, and ends really quite warmly. They seem like genuinely nice people — and if you read Wil Wheaton’s Memories of the Future you’ll find out they really were. That’s nice to know.



  • Hurricane vs. Oil Slick | The Intersection

    I’ve just done a Slate piece elaborating on what would happen if a hurricane hit the Gulf oil slick, based upon further research and interviewing. Here’s an excerpt:
    Much depends on the angle at which the storm crosses the slick. In the Northern Hemisphere, hurricanes rotate counterclockwise, with the largest storm surge occurring where the winds blow in the direction the storm as a whole is traveling—that’s in front of the eye and off to the right. (Meteorologists worry over a hurricane’s dangerous “right-front quadrant.”) So if a powerful storm approached the slick from the southwest, say, its most potent winds would push the oil forward, instead of sweeping it off to the side and out of the storm’s path. If the storm then plowed into the Gulf Coast, you’d expect an oily landfall. And how would the slick affect the storm? Not much if at all:
    …by the time winds reach hurricane force (greater than 74 mph), they cause so much ocean mixing that any oil slick on the surface would be driven down into the depths and generally broken up. MIT hurricane expert Kerry Emanuel has tested the phenomenon on a small scale using an enclosed tank, half filled with water, …


  • Photo safari – barking owl | Not Exactly Rocket Science

    Barking_owl

    This is a barking owl, photographed at Caversham Wildlife Park in Perth. It’s a well-named creature, which, according to Wikipedia, emits noises that “range from a barking dog noise to a shrill woman-like scream of great intensity”. It’s said to be a potential source for Australia’s Bunyip legend, and I’m sure the striking yellow eyes don’t help either.

  • Yammerings: San Diego, New York, and TV | The Loom

    I’ve got some public face time coming up:

    Tuesday, May 25, 5:30 pm: In San Diego, I’ll be talking at the American Society for Microbiology. I was asked to speak at the President’s Forum, “Tell the Story of Science.” My own talk is, “Newspapers, Blogs, And Other Vectors: Infecting Minds With Science In the Age of New Media.”

    Random House will be kindly providing copies of Microcosm for sale at the meeting. I will spend some time signing them all when I get to the conference Monday. The books will be available at the American Society for Microbiology Press Booth. (I’ll update this post when I know exactly where the booth is located.)

    I’ll also plan on hanging out at the booth at some point on Wednesday, hoping that I can meet face to face with some of the Loom’s microbiologist readers. (Again, I’ll update this post about exactly when I’ll be there once I get to the meeting.)

    Thursday, June 3, 7 pm: The World Science Festival returns to New York for its third year, and I’m delighted to enter my third year of moderating panels for them. I’ll be part of “Modern MacGyvers,” a gathering of innovative thinkers who are designing solar panels for camels, cook stoves that could save millions of lives, and other important inventions.

    I may be asked to moderate other panels; if so, I’ll update this post accordingly. I will definitely be going to some other sessions as an audience member: the line-up looks great.

    Thursday June 3, 8 pm and 10 pm: The Science Channel is airing, “Creating Synthetic Life,” a show about Craig Venter’s new hand-made cell. The producers asked me to talk about the research Craig Venter and his team have been carrying out for the past fifteen years on the path to creating artificial life. At the time they interviewed me (a few weeks ago), I knew there was some big news coming down the pike, but wasn’t able to talk about the particulars. So I expect that I’ll turn up on the show speaking in hazy generalities set in the future tense. Feel free to set your TV on mute when I show up. But based on the previews, I think the rest of the show is worth checking out.


  • New Point of Inquiry: Michael Specter on the Menace of Denialism | The Intersection

    My seventh hosted Point of Inquiry episode is now up–it’s with Michael Specter of The New Yorker, and yes, it is about denialism. You can stream it here, and download/subscribe here. Here’s the write up:
    This week, we learned that J. Craig Venter has at long last created a synthetic organism—a simple life form constructed, for the first time, by man. Let the controversy begin—and if New Yorker staff writer Michael Specter is correct, the denial of science will be riding hard alongside it.
    In his recent book Denialism: How Irrational Thinking Hinders Scientific Progress, Harms the Planet, and Threatens Our Lives, Specter charts how our resistance to vaccination and genetically modified foods, and our wild embrace of questionable health remedies, are the latest hallmarks of an all-too-trendy form of fuzzy thinking—one that exists just as much on the political left as on the right.
    And it’s not just on current science-based issues that denialism occurs. The phenomenon also threatens our ability to handle emerging science policy problems—over the development of personalized medicine, for instance, or of synthetic biology. How can we make good decisions when again and again, much of the public resists inconvenient facts, statistical thinking, and the sensible balancing of …


  • Texas: doomed | Bad Astronomy

    Well, that’s that. Congratulations, Texas State Board of Education and the far-right creationist historical revisionists on it. This outcome is not a surprise, but that doesn’t make it any less infuriating, or any less sad. After all the fighting, all the negative publicity, and all the people — including teachers and educational experts — who showed them clearly why they were wrong, the antireality majority on the BoE did what we knew they would do.

    If I were a parent of a school-age child in Texas, I would seriously consider moving to a different state. Because…

  • NCBI ROFL: Kinky quails fertilize more eggs. | Discoblog

    Sexual fetishism in a quail (Coturnix japonica) model system: test of reproductive success.
    “In the present study, the authors explored the reproductive consequences of fetishistic behavior in a previously developed animal model of sexual fetishism (F. Köksal et al., 2004). Male domesticated quail (Coturnix japonica) received sexual conditioning trials in which a terrycloth object (the conditioned stimulus [CS]) was paired with the opportunity to copulate with a female quail (the unconditioned stimulus). Approximately half of the male quail came to copulate with the CS object and were considered to have developed fetishistic behavior. Each of the male quail was then tested with a female quail, whose eggs were incubated to determine rates of fertilization. The CS object was present for 30 s before and during the copulation test. Fetishistic male quail were slower to achieve cloacal contact with the female quail and showed less efficient copulatory behavior. However, they fertilized a greater proportion of eggs than nonfetishistic male quail. These results are unexpected from previous studies of the relationship between reproductive success and copulatory behavior and are discussed in terms of how fetishistic behavior directed toward an inanimate object may modify male-female interactions.” Photo: flickr/ingridtaylar Related content:
