I am pleased to announce that the first volume of the Blue Marble Space Short Story Collection is now available! This volume, titled Tales From Spaceship Earth, includes stories from six different scientists at the Blue Marble Space Institute of Science and is the first in an ongoing series of science-informed fiction.

This collection of stories reflects an intersection of each author’s knowledge of science and vision of the future. These unique perspectives range from the near-term evolution of the space station program, to the beginnings of martian colonies, to the ultimate end of life on Earth–all of which grapple with critical issues of our transformation into a spacefaring society.

This book is available from Amazon as in both paperback and Kindle formats. Proceeds from this collection directly support the research of BMSIS scientists.

Earth’s climate is vulnerable to potential climate catastrophes that could threaten the longevity of civilization. Continued increases in greenhouse gas forcing could lead to the collapse of major ice sheets, which would cause catastrophic sea level rise and could cause the oceanic thermohaline circulation to halt. Further warming could cause the heat stress index to exceed survival limits, inducing hyperthermia in humans and other mammals. Even more extreme warming could shift Earth into a runaway greenhouse regime that would lead to the loss of all oceans, and the end of all life.

Geoengineering refers to the large-scale use of technology to alter Earth’s global climate, and geoengineering has been suggested as a way to ameliorate contemporary climate change. Addressing these immediate climate challenges through a combined strategy of adaptation, mitigation, and (if needed) geoengineering is a critical issue facing us today. Whether or not we decide to engage in geoengineering today, we must still devise a long-term strategy to address our changing climate.

But in the longer-term, could we also use geoengineering techniques to increase the size of the polar ice caps? In a paper published in a special issue of the journal Futures, I raise the question, “Should we geoengineer larger ice caps?” By doing so, the global average temperature of Earth could be lowered from its current state to a new stable regime with much larger ice caps. Earth has experienced shifts in ice coverage in its past, and a prolonged program of geoengineering–say, lasting a thousand years or more–could allow us to permanently shift the energy balance of Earth. More ice at the poles increases the amount of sunlight reflected back to space, leading to cooler temperatures.

Of course, the unfortunate side effects of this idea would be mass migration of populations near the poles, shifts in global agricultural zones, and a required commitment of millenia in order to avoid undesired side-effects. Human civilization today probably lacks the fortitude to embark on such a long-term goal. Nevertheless, thinking about the long-term management of our planetary system helps us realize that we have already entered the epoch of the Anthropocene. Our civilization itself is fundamentally intertwined with our global climate, and we should allow humility, rather than hubris, guide decisions to control our environment.

Global catastrophes are events that could severely cripple or destroy the foundations of civilization. Potential global catastrophes include nuclear winter, large asteroid impacts, super-volcanic eruptions, and pandemics. Humans may not necessarily become extinct under such scenarios, but, without adequate advance preparation, rebuilding civilization following such a catastrophe could prove difficult.

In a paper published in a special issue of the journal Futures, my co-authors and I present several concepts of “Isolated refuges for surviving global catastrophes.” Although catastrophic events could destroy a significant portion of the human population, isolated refuges would provide a way to protect a small group of humans so that they survive long enough to rebuild civilization. We discuss several factors that are critical for ensuring the success of a refuge, including self-sufficiency, a continuous population, secrecy, and adequate monitoring of the outside world.

We also discuss the concept of surface-independence, suggesting that an underground, underwater, or space-based refuge might provide the greatest protection of its inhabitants from the effects of global catastrophes. Any of these refuges could significantly make the human species more resilient to catastrophic threats. Space-based refuges provide an exceptional degree of isolation from Earth, and the cost of such an extraterrestrial refuge might be best “piggybacked” onto existing scientific endeavors that seek to establish a permanent presence on the moon or elsewhere in space.

I’m a bit late on the updates this time, but I figured I’d still list our show dates for posterity.

Sep 5 – Mysterytrain @ Peace of Mind 5 (Elizabethville, PA)

Oct 2 – Mysterytrain @ Duck Duck Goose Family Campout 3 (Northumberland, PA)

Oct 3 – Mysterytrain @ Froggy Daze 2 (Narrowsburg, NY)

Nov 14 – Mysterytrain @ City Jam II (Reading, PA)

City Jam was lots of fun, and hopefully we’ll find ourselves back this winter. In the meantime, check out the newly-redesigned Mysterytrain website!
