SF Seasons

Happy New Year! The days begin to lengthen, even if imperceptibly at first, but nevertheless I have to brace myself for over two months more of early darkness and damp cold. We temperate-zone residents are used to a year divided into the conventional four seasons, recurring in a predictable annual rhythm. My family had a funny encounter many years ago at King's Dominion (an amusement park) in northern Virginia, while standing in line to check out of the hotel adjacent to the park. This happened on a day at the height of summer, and the weather was as expected in a Virginia summer, high humidity with temperatures in the eighties or low nineties. An apparently British couple in line with us asked whether "it was always this hot" all year around. Mentally (not aloud, of course) I collapsed with laughter. In this area we have four seasons just like most other locations in North America, with pleasant springs and falls and miserably cold winters. If our family's experience of living in Hawaii in the 1970s was typical, tropical regions have two basic seasons, rainy and dry, with little variation in temperature or length of daylight.

Science fiction and fantasy often feature imaginary worlds with seasons different from those familiar to us Earth dwellers, but the stories don't always take full advantage of the possibilities. The setting of the Game of Thrones saga famously suffers winters that last for years, whose timing and duration vary. Yet I don't remember noticing in either the novels or the TV series an explanation of how human civilization in Westeros survives those ordeals. How could enough food possibly be stored to sustain entire nations over a multi-year winter, especially with no way of knowing when the cold season will descend upon them? Maybe the southern regions of the inhabited world escape mainly unscathed and supply provisions for the affected areas? The economic effects would be calamitous, though, even if most people managed to scrape by. Isaac Asimov's classic story "Nightfall" takes place on a planet in the middle of a cluster of stars, so that it experiences full darkness only once in several centuries. Although a short story can't cover every aspect of worldbuilding, admittedly, even in the story's later novel-length expansion I don't recall any consideration of how different a culture that develops in perpetual light would be from ours. Agriculture alone would evolve in ways strange to us, wouldn't it? Recently I read SHADOW AND LIGHT and SHADOW RISING, the first two books in an excellent fantasy series by Peter Sartucci. They're set on a planet that revolves around a double star. No results of having two suns, in terms of either circadian rhythms or climate, are developed. As in "Nightfall" with its planet of multiple suns, not only weather but seismic phenomena would surely be affected. With more books to come, however, maybe this aspect of the setting will be elaborated later.

One novel I've read within the past year takes full advantage of its setting's weird seasons, as the title indicates: THE FIFTH SEASON, first book in the Broken Earth series by N. K. Jemisin, offers a devastating, in-depth portrayal of a world periodically ravaged by geological disasters of apocalyptic scope. Fifth Seasons appear at unpredictable intervals and can last from a few months or years to an entire century. At those times, worldwide tectonic cataclysms cause earthquakes, volcanoes, and tsunamis, with side effects such as climate change, crop failures, poisonous fungal growths, etc. Appropriately, this world's cultures are crucially shaped by the Fifth Season phenomenon, which includes the ambiguous role of the few people with the gift of controlling seismic events.

Here's a page that lists eight SF novels about climate change:

And here's a different list of fourteen novels focusing on climate catastrophes (including some overlap with the previous one, naturally):

Carter's Crypt

Microworlds

Imagine pores in a human skin. If you wish, imagine blackheads in pores in human skin. Now imagine each dark pore is teeming with life forms, and each one contains a slightly different and isolated ecosystem.

You'd have a one disgusting world, wouldn't you?  Or myriad disgusting microworlds.

There is a similar phenomenon in the world's glaciers, and there is a 3-page, illustrated story about it in this month's DISCOVER magazine. The authors of that article mention man-made global warming, and say that the cryoconite phenomenon is exacerbating the melting of the glaciers.

As I read about the sticky airborne bacteria flying through the air, gathering up dark dust and fragments of salts and minerals and black waterbears, then landing on glacial ice and absorbing sunlight into the dark matter and thus melting tiny holes the ice like road salt does on iced roads, I thought of all the recent volcanic activity.

I don't think the article mentioned volcanic ash, but the focus was on how the tiny dark pools form, and how ecosystems are created and fed by sunlight and photosynthesis, and how the dark dust sinks to the bottom, attracting warmth and sunlight, and increasing in size, and life thrives and evolves.

Volcanoes seemed more likely to me, especially since there was Eyjafjallojokull in 2010 (which shut down most of the European airports for several days) and then the biggest series of Icelandic volcanic eruptions in centuries through 2014, and more in 2015.  One can find a list of which volcanoes are currently erupting here: http://www.volcanodiscovery.com/erupting_volcanoes.html and more about volcanoes here: http://www.volcanodiscovery.com/news.html 

How can one talk about dark dust on glaciers and not talk about volcanoes?

So, I googled "volcanoes + cryoconite", and sure enough, someone--Patrick R Dugan PhD-- has written an excellent and highly informative book about the effect of volcanoes on "climate change" and on glaciers.

With my copyright activist hat on for a moment, I have to express my astonishment that Google displays over 40 consecutive pages of a 64 page book that is in copyright and for sale on Amazon. How that is an insignificant snippet of the work that cannot affect sales... is beyond my comprehension.

As one might expect, volcanoes throw up an uncommon mixture of minerals, salts, fragments of rock,  ash, dust, and no doubt bits of whatever happened to be living on the top or side of the mountain before it erupted. That explains the waterbears in the air!

As a writer of alien romances, I imagine alien worlds from time to time, and --forgive me if I've mentioned it previously-- I like the idea of multiple ecosystems developing in parallel, and in otherwise hostile surroundings.

All the best,
