earth03 Climate Change  Part 2: Solastalgia

Solastalgia: the sadness caused by environmental change or loss.

Solastalgia: the distress caused by the lived experience of the transformation of one’s home and sense of belonging and is experienced through the feeling of desolation about its change.

“Australia is suffering through its worst dry spell in a millennium. The outback has turned into a dust bowl, crops are dying off at fantastic rates, cities are rationing water, coral reefs are dying, and the agricultural base is evaporating,” wrote Clive Thompson of Wired Magazine last December in a compelling article on “How the Next Victim of Climate Change Will Be Our Minds”.

Glenn Albrecht (professor at the School of Environmental and Life Sciences at the University of Newcastle) described his fellow Australians’ reactions:

“They’re getting sad.”

Australians described a deep sense of loss as they watched the landscape around them change and deteriorate: familiar plants not taking; gardens not growing; birds disappearing… Albrecht believes this to be a new type of sadness, a feeling of displacement. “They’re suffering symptoms eerily similar to those of indigenous populations who were forcibly removed from their traditional homelands,” said Thompson.

Albrecht gave this syndrome an evocative name: solastalgia. It encompasses the roots of solacium (solace) and nostos (return home) with algia (pain)—yet another paradox that aptly conjures the word nostalgia. In essence, says Thompson, it’s “pining for a lost environment.”

“The homesickness you feel when you’re still at home,” says Albrecht.

“It’s fascinating…to think about the impact of global warming,” says Thompson. “Everyone’s worrying about resource management and the spooky, unpredictable changes in the ecosystem. We fret over which areas will get flooded as sea levels rise. We estimate the odds of wars over clean water, and we tally up the species—polar bears, whales, wading birds—that’ll go extinct.” But, Thompson warns that we should also be concerned about the huge toll climate change will inflict on our mental health.

During his research, Albrecht noticed that the more quickly environmental change occurred, the more intense the solastalgia. For instance, in the Australian outback, where open-pit mining has created moonscapes seemingly overnight, the suicide rate in the region skyrocketed. In New Orleans, a Harvard study revealed that survivors of Hurricane Katrina reported suffering a “serious mental illness” at about double the rate of the city’s residents three years earlier. Although trauma and personal loss played a large role, one should not discount the powerful effect of physical environmental loss as well.

All this reminded me of the nightmare I suffered last month and the nagging thoughts of climate change that have lingered with me since then…nay, since my earlier experience of that unseasonal tornado in Louisville, Kentucky. Albrecht has given what I feel a name: Solastalgia.

Where I live I don’t personally experience strong environmental change (with the exception of the odd weather mishap like ice storms and atypical snow for this Med Climate Change  Part 2: Solastalgiaiterranean climate). In fact, we are having a wonderful spring season here, with the cherry trees and the crocuses in my garden already blooming and tulips not far behind. But, while I don’t see the devastation and change around me, I feel it. Acutely. Since childhood, I remember having this feeling, this emotional link to my beloved planet and a growing sadness for what we are doing to it (the reason I pursued a science degree and became an environmental consultant). I still remember being sternly lectured by a high school teacher about my “misdirected” efforts to enlighten my school about global pollution. “You’re putting up posters about taking care of the planet when you should be focusing on your neighbourhood,” he chided me. It was then that the penny dropped for me: not everyone thought about their planet like I did.

But, surely, we are all part of Gaia. Let me rephrase: surely, we ARE Gaia…the woman walking her child to school…the young grocery boy taking your bags to the car… the blooming cherry trees growing along the side of the road…the birds singing on the power lines…the clouds scudding overhead or the rain spattering our faces… We ARE the planet, the living, breathing planet Earth. And the malaise of our planet is our own malaise. Humanity’s malaise.

Most of us reading this post live in a fast-paced stressful world, where many of us find ourselves coping day-to-day to “survive” the copious demands on our time, energy, brains and feelings. How can anyone in that frame of mind be expected to willingly take on the burden of thinking about the entire planet?!? Are we trapped in a shockwave of fretful living without even realizing it? “In a world of cheap airfares, laptops, and the Internet, we proudly regard mobility as a sign of how advanced we are,” Thompson quips sarcastically, “Hey, we’re nomadic hipster capitalists!…Only losers get attached to their hometowns.” Only losers care about their environment…

I am reminded of Fritz Lang’s Metropolis, the 1927 classic dystopia about the social crisis of a world where the selfish “dreams of a few had turned to the curses of many” (Fritz Lang, Metropolis). There is a scene in this evocative film where creative men of antiquity decide to build a monument to the greatness of humanity, high enough to reach the stars and reminiscent of humanity’s hubristic construction of the Tower of Babel. It is a world domMetropolis new tower of babel Climate Change  Part 2: Solastalgiainated by technology and the greed of few; where the bulk of the people are dehumanized workers, who more resemble machines in their jerky rhythmic movements and laconic faces than the oppressed humans they are. It is a world whose “heart” (the intermediary) is missing between its “brain” (those who conceive and run the city) and its “hands” (those who labor to make it a reality).

And I am reminded of Sodom and Gomorrah, destroyed by “brimstone and fire from the Lord out of Heaven.” The rabbinic tradition, described in the Mishnah, teaches that the sin of Sodom was related to property: Sodomites believed that “what is mine is mine and what is yours is Sodom and Gomorrah Climate Change  Part 2: Solastalgiayours,” which was interpreted as lack of compassion. Classical Jewish texts describe the sins of Sodom as cruelty and lack of hospitality to the stranger.

In the Bible, God said: Now, this was the sin of Sodom: She and her daughters were arrogant, overfed and unconcerned; they did not help the poor and needy. They were haughty and did detestable things before me. Therefore I did away with them as you have seen—Ezekiel 16: 49-50.

Some Kabbalistic mystics (e.g., Menachem Tsioni; others) described the Tower of Babel as a functional flying craft, empowered by powerful magic and/or technology and originally intended for holy purposes but later misused to gain control over the world. An escape ship, perhaps? A kind of arc? We have no flying tower. We just have Gaia. Our home. And what are we doing to our home?

Laments Thompson, “In a world that’s quickly heating up and drying up, you can’t go home again—even if you never leave.”

earth Climate Change  Part 1: Human Health—Friday Feature

This is the first in a new series I’ll be posting that deals directly with climate change, a topic of great controversy among scientists still and one meriting discussion among us here. Okay, I lie: I posted several articles already that touch on this subject. I touched upon the chaotic nature and interrelatedness of climate and weather in my post on chaos theory. In two blog postal gore Climate Change  Part 1: Human Health—Friday Features, “Climate Change & the Nobel Peace Prize” and “Blog Action Day—Truth”, I devote lengthy discussion to the dedicated work of Al Gore, his film, “the Inconvenient Truth” and generate lively discussion on the topic (check out the comments pages!). In “Tornadoes Connected to Global Waming?” I described my own personal experience with the tornado02 Climate Change  Part 1: Human Health—Friday Featurehistoric unseasonal tornadoes in the US earlier this year and how some believe this is related to climate change and is a sign of more to come. In “Polar Cities” I describe Dan Bloom’s concept for surviving the aftermath of global warming and explore the need for paradigm changes. Then in “The Complexity of Nature” I discuss how perspective plays a role in our perception of both our future and that of our planet.

I left off with a discussion—actually a series of questions—related to “scale” and whether or not we should intervene, when everything that we are and do is PART of the global network already. Is it simply that we are being hubristic once again by seeing things from a strictly anthropomorphic view? Perhaps, it isn’t our place to succeed, but rather to secede to something more suited to what is yet to come… I’d like to think that it may be neither, rather that these global events will hasten our own evolution into a higher form. But I’m getting way ahead of my own series. Because today’s post is entirely from a human’s viewpoint and concerned with our own well being. Much of the information here is from an article written by the medical community in Nova Scotia, Canada. I start wclimate change01 Climate Change  Part 1: Human Health—Friday Featureith some very interesting statistics. For instance, did you know that:

  • Close to 8% of all non-accidental deaths in Canada are caused by air pollution resulting from by-products of burning fossil fuels.
  • Following smog days, hospital admissions for respiratory problems increase by 6%, admissions of infants with respiratory problems increase by 15%.
  • Forecasts show that without reductions in fossil fuel consumption, in 20 years there will be a 60% increase in particulate emissions with a corresponding increase in respiratory illnesses, hospitalization and health care costs.

A report by the US National Academies’ National Research Council, Abrupt Climate Change: Inevitable Surprises, warns that people can expect “climate surprises” in the form of “large, climate change hurricane Climate Change  Part 1: Human Health—Friday Featureabrupt and unwelcome regional or global climatic events,” including drought, floods, extreme heat, hurricanes, (how about unseasonal tornadoes?…) and rising sea levels. Dr. Paul Epstein, associate director of the Center for Health and the Global Environment at Harvard Medical School, says the report indicates that “we’ve underestimated the rate of this change, we’ve underestimated the sensitivity of biological systems, we’ve underestimated the cost of global warming.”

Epstein and other authors published a paper in the Canadian Medical Association Journal where they suggested that the direct effects of climate change to humanity include: illness and deaths from heat waves, drought, floods, storms and the breakdown of systems in the aftermath of weather disasters. Indirect effects would include decreased crop productivitclimate change02 Climate Change  Part 1: Human Health—Friday Featurey owing to pests and climate change, changing water availability, lower air quality, rising sea levels and animal-based diseases appearing in regions in which they had previously been unheard of.

I dedicate this Friday Feature page to the stellar websites and blogs devoted to educating us, challenging us and guiding us on climate change, some of which appear below. Please check them out and let me know of any sites you think should be included that I’ve neglected to include.

arthur c clarke06 Arthur C. Clarke—Homage to a Visionary

The only way of finding the limits of the possible is by going beyond
them into the impossible
—Arthur C. Clarke

When I was in my early twenties (some time ago) I read Childhood’s End by Arthur C. Clarke. He’d written it a year before I was born. I remember being moved by the story’s grandness and scope about the transformation of humanity. On the slightly garish cover of the Ballantine science fiction classic book jacket Gilbert Highet’s endorsement said, “…a real staggerer by a man who is both a poetic dreamer and childhoods end Arthur C. Clarke—Homage to a Visionarya competent scientist.” This remains an apt assessment of this self-professed “mildly cheerful” British science fiction author, inventor, and futurist, perhaps best known for the novel 2001: a Space Odyssey (also about the transformation of humankind).

On March 19 of this year, Arthur C. Clarke died at age ninety in Colombo, Sri Lanka, where he’d made his home since 1956. He left behind a legacy of incredibly imaginative works, valuable scientific inventions and concepts and profoundly thoughtful discussions of the future.

During the time Clarke served in the Royal Air Force as a radar instructor and technician (from 1941 to 1946) he proposed satellite commuarthur c clarke02 Arthur C. Clarke—Homage to a Visionarynication systems, which won him the Franklin Institute Stuart Ballantine Gold Medal (in 1963) and a nomination in 1994 for a Nobel Prize. What you might not have known about him is that he was an avid scuba diver and helped fight for the preservation of lowland gorillas, which won him the UNESCO-Kalinga Prize in 1962. Clarke was also fascinated with the paranormal and admitted that it was part of the inspiration for his novel Childhood’s End. He was named a Grand Master by the Science Fiction Writers of America in 1986. And in 2000, he was knighted. Yes, he is Sir Arthur Charles Clarke. He served as the first Chancellor of the International Space University from 1989 to 2004, has an asteroid named in his honour and a species of ceratopsian dinosaur (Serendipaceratops arthurcclarkei), discovered in Inverloch in Australia.

Born in Minehead, Somerset, England, Clarke enjoyed stargazing and reading old American science fiction pulp magazines when he was a boy. His first professional sales (e.g., Loophole and Rescue Party)appeared in Astounding Science Fiction in 1946 at age 29. In 1948, Clarke wrote The Sentinel for a BBC competition; although it was rejected it represented a turning point in Clarke’s writing, which introduced a more mystical and cosmic element to his work (the Sentinel was the basis for his best known work, 2001: A Space Odyssey). Many of his subsequent works (including Childhood’s End) features the theme of a technologically advanced but prejudiced humankind being confronted by a superior alien intelligence—the encounter of which prarthur c clarke04 Arthur C. Clarke—Homage to a Visionaryoduces a conceptual breakthrough that accelerates humanity into the next stage of its evolution.

Among Clarke’s visionary science (fiction) and inventions, some of his most notable include the following:

  • Geostationary satellites as telecommunications relays (described in a paper in Wireless World, October 1945 entitled, Extra-Terrestrial Relays—Can Rocket Stations Give Worldwide Radio Coverage?) The geostationary orbit 36,000 km above the equator is officially recognized by the International Astronomical Union as a “Clarke Orbit”;
  • Space elevators (first described in The Fountains of Paradise, 1979); and,
  • A “global library” (in Profiles of the Future, 1962).

We get a good sense of Clarke’s beliefs and philosophy in his works. In his introduction of Mysterious World: Strange Skies, Clarke said, “I sometimes think that the universe is a machine designed for the perpetual astonishment of astronomers.” At the end of the episode, of the Star of Bethlehem (of which his favorite theory was that it was a pulsar) he added, “How romantic, if even now we can hear the dying voice of a star which heralded the Christian Era.”

Iarthur c clarke03 Arthur C. Clarke—Homage to a Visionaryn the 1973 revision of his 1962 book, Profiles of the Future, Clarke added two laws to create his famous three laws of prediction, aptly termed Clarke’s Three Laws:

1. When a distinguished but elderly scientist states that something is possible, he is almost certainly right. When he states that something is impossible, he is very probably wrong.
2. The only way of discovering the limits of the possible is to venture a little way past them into the impossible.
3. Any sufficiently advanced technology is indistinguishable from magic.

Fiction is more than non-fiction in some ways…you can stretch people’s minds, alerting them to the possibilities of the future, which is very important in an age where things are changing rapidly—Arthur C. Clarke

Clarke’s most notable works include 2001: A Space Odyssey, Rendezvous with Rama, Childhood’s End, The Fountains of Paradise.

cassini flyby5 Cassini Flies over Enceladus

Today “Cassini is set to begin a series of scraping Enceladus flybys that will take place in 2008 and will take us flying within a mere 50 km (~ 30 miles) over the equatorial region of the moon, approaching from the north and then departing towards the south, with passage through the edges of the moon’s famous south polar plume” said Catheryn Porco, Cassini Imaging Team Leader. At closest approach, the spacecraft will pass the moon at a speed of about 14 kilometers (9 miles) per second. “We will make several daring plunges over the surface of Enceladus and through its plume of vapor and icy particles,” said Porco. “These maneuvers will take us deep into the plume and allow many of Cassini’s instrument teams to improve their measurements of the region’s properties. The heat-sensing instrument will map the tcassini flyby3 Cassini Flies over Enceladuserrain’s thermal emission over a wider area than before in search of additional hot spots, and the instrument capable of sniffing out the plume’s composition will improve tenfold its measurements of the plume’s molecular concentrations. All of us are eager to learn if we are correct in suspecting that organic-rich, liquid water reservoirs are truly the sources of the moon’s dramatic geologic activity…We should come away, in particular, with a better measure than we’ve had up until now of the abundances of ammonia and some simple organic compounds, both of which are important to ascertaining the astrobiological potential of the source environment of the jets.”
The Voyagers showed that Enceladus is only 500 km in diameter and reflects almost 100% of the sunlight that strikes it. Voyager 1 found that Enceladus orbited in the densest part of Saturn’s diffuse E ring, indicating a possible association between the two, while Voyager 2 revealed that despite the moon’s small size, it had a wide range of terrains ranging from old, heavily cratered surfaces to young, tectonically deformed terrain, with some regions with surface ages as young as 100 million years old.

The Cassini spacecraft of the mid- to late 2000s acquired additional data on Enceladus, answering a number of the mysteries opened by the Voyager spacecraft and starting a few new ones. As a result of several close flybys of Enceladus in 2005, the probe discovered a water-rich plume vcassini flyby jetson enceladus Cassini Flies over Enceladusenting from the moon’s south polar region. This discovery, along with the presence of escaping internal heat and very few (if any) impact craters in the south polar region, shows that Enceladus is geologically active today. Moons in the extensive satellite systems of gas giants often become trapped in orbital resonances that lead to forced libration or orbital eccentricity; proximity to the planet can then lead to tidal heating of the satellite’s interior, offering a possible explanation for the activity.

Enceladus is one of only three outer solar system bodies (along with Jupiter‘s moon Io and Neptune‘s moon Triton) where active eruptions have been observed. Analysis of the outgassing suggests that it originates from a body of sub-surface liquid water, which along with the unique chemistry found in the plume, has fueled speculations that Enceladus may be important in the study of astrobiology.The discovery of the plume has added further weight to the argument that material released from Enceladus is the source of the E-ring (Wikipedia).

Enceladus was named after the Titan Enceladus of Greek mythology. The name was chosen because Saturn, known in Greek mythology as Cronus, was the leader of the Titans.

The Cassini-Huygens mission is a cooperative project of NASA, the European Space Agency and the Italian Space Agency. The Jet Propulsion Laboratory, a division of the California Institute of Technology in Pasadena, manages the Cassini-Huygens mission for NASA’s Science Mission Directorate, Washington, D.C. The imaging team consists of scientists from the US, England, France, and Germany. The imaging operations center and team lead (Dr. C. Porco) are based at the Space Science Institute in Boulder, Colo.For more information about the Cassini-Huygens mission, visit http://saturn.jpl.nasa.gov and the Cassini imaging team home page, http://ciclops.org.

dreams01 Dreams, REM & Theta Rhythm

Dreams may reflect a memory-processing mechanism inherited from lower species
—Jonathan Winson


There are more things in heaven and earth, Horatio, Than are dreamt of in your philosophy–William Shakespeare

Human beings have long sought to understand the meaning or value of dreams. Ancient Egyptians were convinced that dreams possessed oracular powers. In other cultures dreams have been described as inspirational, curative or as alternative reality. Sigmund Freud suggested in his publication The Interpretation of Dreams in 1900 that dreams were “the royal road” to the unconscious, that they revealed in disguised form the deepest elements of a person’s inner life.
Since Freud, scientists have variously suggested that dreams were either totally meaningless—simply the result of random nerve cell activity—or that they were a way for the brain to rid itself of unnecessary information, like ‘unlearning’.

Recent work by scientists, including Jonathan Winson out of Rockefeller University, suggest that Rapid Eye Movement (REM) sleep and brain waves called theta rhythm play key roles in the processing of memory. It is only during REM sleep that we dream. Durindreams02 Dreams, REM & Theta Rhythmg REM sleep neural signals, called pontine-genidulate-occipital (PGO) cortex spikes, move from the brain stem to the centre of visual processing, the visual cortex. At the same time a sinusoidal wave is initiated in the hippocampus, called theta rhythm.
Discovered in 1954 by John D. Green and Arnaldo A. Arduini of the University of California at Los Angeles, theta rhythm was found in most animals tested, and mostly in awake animals. Researchers found that theta rhythm was evoked during moments when an animal was behaving in ways most crucial to its survival; in other words, it appeared during moments when they were responding to changing environmental information, rather than to something they were genetically encoded for, like feeding or sexual behaviour. The presence of theta rhythm during REM sleep, generated in the hippocampus—where memory processing occurs—suggested that theta rhythm reflected a neural process in which information essential to survival of a species, gathered during the day, was reprocessed into memory during REM sleep.
The dreams04 Dreams, REM & Theta Rhythmhippocampus, together with the neocortex, is believed to provide the neural basis for memory storage, according to Winson. His studies showed that theta rhythm was produced in two regions in the hippocampus: the dentate gyrus and the CA 1 neurons and that the rhythms of these two were synchronous. James N. Ranck, Jr. and Susan Mitchell of the State University of New York identified a third synchronous generator in the entorhinal cortex.
Robert Verdes of Wayne State University then discovered that neurons of the brain stem transmit signals to the septum of the forebrain to activate theta rhythm in the hippocampus and the entorhinal cortex.
Scientists in the 1970s demonstrated that a change in neural behaviour reflecting previous activity, called long-term potentiation (LTP) depended on the presence and phase of theta rhythm. For instance, as a rat explores, brain stem neurons activate theta rhythm.
Not all animals experience REM sleep; the echidna (a monotreme) experiedreams03 Dreams, REM & Theta Rhythmnces slow-wave but not REM sleep. As a consequence, it does not exhibit theta rhythm when asleep either. Without theta rhythm during REM sleep, the echidna must rely on its larger prefrontal cortex to perform a dual function: to react to incoming information and to evaluate based on past experience and store new information. Winsom suggests that REM sleep—and dreams—may have evolved to help an animal to survive, by helping to reprocess information.
It is interesting to note that infants and children spend a large amount of their sleep time in REM sleep. Newborns spend eight hours a day in REM sleep; by the time they’re two years old, children have reduced their REM sleep to three hours a day with adults spending about two hours in REM. Scientists suggest that REM sleep stimulates nerve growth.
