Climate Change–Part 1: Human Health—Friday Feature

March 29, 2008

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 posts, “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 historic 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 with 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, abrupt 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 productivity 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.

Nina’s Booktour Continues

March 27, 2008

Almost two weeks ago, and with great coverage by the local press (the Surrey Leader), I fulfilled a fantasy by appearing at the Strawberry Hill Chapters store in Surrey, British Columbia, to sign my book, Darwin’s Paradox. Once or twice a month I used to meet three other friends who’d formed a writer’s group we’d called Critical Ms. Starbucks coffee in hand, I met them in the small alcove with comfortable chairs to trade industry stories, critique each other’s work, and dream of having my book on the shelf behind us (it was the science fiction section of the store). Last week I realized that dream and more! What’s really cool is that one of the other Critical Ms writers, Lois J. Peterson, is also launching her book this fall. It’s a YA novel called, Meeting Miss 405 by Orca Press. I even had a surprise visit from Brian Hades of Edge Publishing, the parent company of Dragon Moon Press—he was just passing through town… Sure! Brian had found these cool see-into-the-future glasses at a strange Vancouver antique shop and thought of me… funny that…But don’t I look intelligent in them?…

My signing at the Granville & Broadway Chapters store in Vancouver the following week was yet another adventure. As always, I met very interesting patrons, including two Romanian ladies (Silvia Boiceanu and Maria Moise) who, after introducing themselves, decided to linger and watch me “in action” and occasionally waved at me, smiling. I also met Twyla Anderson, a budding novelist and practiced my French with Agnes Lacombe, an elegant lady from France. Hildegard Zander engaged me in a long philosophical conversation that ranged from the transcending songs of French singer Gilbert Becaud to the environmental basis of cultures.

Then Stephen Saint Laurent, Prince George videographer, stopped by and gave me an impromptu interview. I also had the unexpected pleasure of meeting a long-time friend who I hadn’t seen in a while. She’d spotted Chapter’s billboard advertisement outside the store and had noted the time. Barb Meier is a talented artist and craftsman who makes books from scratch (paper, cover and binding!). That’s Barb pointing at my display. My sister, Doina Maria (and my partner in imagination from when we were kids) is standing beside her. She’d come to lure me away with promises of calamari and red wine.

My book signing at the Granville store experienced some added excitement as a student rally of over 500 protesters passed the store in a flourish of banner waving and boisterous shouting. The patrons of the store, myself included, emerged to watch as police-escorted demonstrators waving “Free Tibet from China” signs and shouting slogans, marched past us. Tibetan supporters from Vernon to Victoria were rallying against the violence in the tumultuous Chinese-controlled region; they marched from the art gallery to the Chinese consulate, where they chanted, burned Chinese flags and acted out scenes of violence.

I will finalize my local book tour with a signing at Blackbond Books in Richmond and a Chapters store in Burnaby (Metrotown). Then I’ll be flying to Paris, France where… I think Darwin will take a holiday with me. Truthfully, I am travelling there (and possibly to Berlin) to research my next book, a historical fantasy about a young girl in medieval Prussia who discovers that she can alter history. More on that in another post…


Arthur C. Clarke—Homage to a Visionary

March 25, 2008

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 a 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 communication 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 produces 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.”

In 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 Flies over Enceladus

March 12, 2008

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 terrain’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 venting 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.
